Good riddance. Psychiatry by and large is a sham field. Physicians who practice it love seeing themselves as artists who are experts in identifying the subtleties of human behavior. That's their way of saying there's very little underlying science guiding their practice.

Many of the diagnoses given are pulled out of thin air and made to justify a patient's admission, or to appease a patient's desire to feel as if they have a treatable illness. I would ask psychiatrists I trained with to explain why a drug worked or why a disease developed. They would do nothing more than give me the same surface-level information we all know: SSRIs block serotonin reuptake, leading to more serotonin in the synaptic cleft that would then cause increased stimulation, and voila, you're not depressed. This is information anyone can attain with a google search. The majority of their knowledge dealt with pharmacological dynamics.

I sat in on a psychiatry conference one afternoon where the docs discussed the treatment of several patients. Never was a scientific article or concept uttered. It was all "well, let's try him on seroquel and olanzapine, let's also throw Paxil in there." It was evident that their treatment protocol was largely one of extremely unsupported trial-and-error based on very, very unique experiences, anecdotes, and preferences each psychiatrist had.

Now, I don't want to discredit the entire field. I do know friends and family who have benefited from psychiatric medications, although that could entirely be due to placebo effect. What needs to happen first is that we need to attain a much deeper understanding of how the brain works on the low and high levels, mechanically and abstractly. Mechanically so that we may develop effective meds, abstractly so that we may learn how to manipulate cognitive processes, like with what we see with CBT, which has worked wonders for many with depression -- no medication involved.

tl;dr: Psychiatry is a very, very loose and abstract field. You can't run any diagnostic tests on patients. It's mostly a field of educated guessing and confirmation bias. We need better mechanical and abstract understanding of the mind before we douse it in chemicals.

As a young engineer-type with no exposure to the psych field, I had about the same opinion when I was in my early 20's.

However, a few decades of real life later I've seen first-hand, successes and turnarounds for people who either found themselves in bad situations or were just plain genetically vulnerable. In fact, I'll go as far as saying that counseling or therapy are nothing compared to the difference that the right medication(s) can make in a life. Finding it is hit-or-miss, and there are still people who ultimately can't be helped but there are countless success stories - they just aren't worth reporting, like every time antibiotics work as expected.

Re:The psychiatric drug crisis by kyro on Saturday September 07, 2013 @09:31PM (#6347430)
I agree with you for the most part. There are people with severe, debilitating conditions that may require medical intervention.

There are many, many more that have been labeled due to loose diagnosing guidelines to have a psychiatric disorder. A psychiatrist might just notice that your affect is slightly off, and label you with schizoaffective disorder, which is pretty well known as the diagnosis you give when you can't really put your finger on what's wrong, and yet they still treat medically.

How many people diagnosed with MDD or hypomania, do you think, genuinely deserve treatment with muddy medications? How many of them do you think may have other rectifiable issues that are leading to their disposition? Psychiatrists tend to overlook identifying those issues, and jump to asking the questions needed to diagnose a disease as per the DSM-IV.

Exactly right. Missing from the article is a sense of just how far these drugs have allowed us to come as a society. Researching the history of mental illness treatments is almost as horrifying as reading about slavery. For serious illnesses it could be horrific.

Today, many powerful mental illnesses can be brought under control by medication. For example, the brother of a close friend suffers from schizophrenia. His drugs work so well that the biggest risk he faces is deciding that he feels so normal that he's cured, and can stop taking the drugs (which would result in a relapse).

Re:The psychiatric drug crisis by jdietrich on Sunday September 08, 2013 @12:54AM (#6347875)
Homeopaths and faith healers say exactly the same thing. Personal anecdotes are not data.

Most mental health disorders are inherently self-limiting and will disappear without any treatment, which makes psychiatry look far more effective than it really is. If you're depressed, you're statistically likely to not be depressed in six months time, regardless of whether you seek treatment or not. In these circumstances, it's easy for a completely ineffective treatment to look like a miracle cure. The key outcome measures for most psychiatric drug trials are episode duration and likelihood of relapse, which speaks volumes.

From Wiki http://en.wikipedia.org/wiki/Major_depressive_episode:

If left untreated, a typical major depressive episode may last for about six months, while about 20% of these episodes can last two years or more, with 50% of depressive episodes ending spontaneously.

I can probably find you an article reference if you want. But I have learned this kind of research findings in psychology class.

Re:The psychiatric drug crisis by mtdewcmu on Sunday September 08, 2013 @09:24AM (#6348614)
There's also a such thing as chronic depression, and reason to think that major depression follows a relapsing-remitting course, at least in some people, and may turn into or be a warning sign of developing chronic depression.

Which says nothing about the effectiveness of psychiatric treatments. But it does argue for aggressive early treatment, whatever that might mean, in the hope of halting the progression before it could become chronic.

Mental illness is fundamentally hard to study scientifically, and I'm not convinced that any of the treatments we have actually work. But it's humane to make the attempt.

No depression treatment is claimed to have an immediate effect. If you start taking SSRIs and immediately feel better, it's pure placebo - the marketers of those drugs say that SSRIs take weeks to show any noticeable effect.

One data point? You're talking about the 'how are we going to treat our current patients' conferences? I've been in a couple of those myself, and you're expecting something weird from them. It'd be like spending the afternoon with engineers and saying "I didn't hear any of them mention any of the laws of thermodynamics!".

I've worked with engineers building hardware, both medical and agricultural, and much of their day-to-day work is based on their innate understanding of the tasks at hand. At critical points in the design process, they will break out their formulas, but when they're discussing the generalities of what to do with their colleagues, they're not citing canonical resources. What you're desiring is a fantasy world.

You can't run any diagnostic tests on patients.

As someone who spent several years as a neuro tech, this isn't true. Some things have some tests. It is a very difficult field of study - possibly the most difficult in all of human experience - and it's true that there isn't a great amount of test coverage over the whole field. But you're mischaracterising it to say there are no tests.

We need better mechanical and abstract understanding of the mind before we douse it in chemicals.

That's a nice throwaway line. You make it sound like the mind is an easy thing to understand, and that it won't take long. And apparently, until we have this complete understanding, we should just say 'fuck you' to the people who are currently in need of help?

Overuse of pharmaceuticals is a problem, but the answer isn't to run screaming into the absolutist opposite direction.

Re:The psychiatric drug crisis by kyro on Saturday September 07, 2013 @10:46PM (#6347591)
1. I've sat in on multiple psych conferences. If you compare them with conferences in other specialties, you'll soon realize that there is a severe lack of scientific discourse happening. As I said, there is a belief that the field is an art and that the practitioners within are artists who rely heavily on their experience and preferences. Literature is hardly discussed. The DSM is the bible.

2. Yes, the best and most practical test we have is an EEG that, at best, tells you that something wonky is going on in this vague region of the brain. Good for seizure disorders, little else. The other tests we can run are to detect physiological causes of psychiatric symptoms external to the brain, like thyroid disorder, uremia, overdose, etc. Nobody sends a patient down for a routine fMRI. What tests are you referring to?

3. I'm not advocating to wait until we've achieved a complete understanding of the brain, but rather we explore more conservative managements while we get a better understanding of the mechanical workings on the brain. CBT, DBT, psychotherapy, etc, should be actively encouraged by psychiatrists as first-line options for many of these conditions. They simply aren't.

Re:The psychiatric drug crisis by neurotech1 on Saturday September 07, 2013 @11:56PM (#6347761)
The Quantitative EEG(qEEG) can determine more than seizure type disorders. The EEG relative signal amplitude is compared to a database. This can sometimes provide a useful differential diagnosis, but not substitute for good clinical assessment and lab work.

Unlike psychiatrists, I do not believe the DSM criteria can substitute for actual clinical diagnostic skills.

Re:The psychiatric drug crisis by shubb on Sunday September 08, 2013 @08:56AM (#6348563)
I find your comparison with engineers interesting. There is rigorous work on 'which agile methodology delivers most benefit' or 'what is the best way to architect a system', but largely that stays in academia. I don't think many programmers refer to high quality studies when choosing to do extreme programming over scrum.

The reason for that is the complexity and uniqueness of projects (Does that study at IBM really apply to my small company? If this is a good way for NASA to make hardware, is it a good way to design android aps?). But also because engineers are focused on doing a job using a body of knowledge they draw from school, experience, and a bit of reading. They are not academic engineers. This is probably a good thing.

Similarly, I think doctors are not academic researchers. They apply treatment algorithms, bending them to the patients specific situation is so far as won't get them sued.

If the algorithm doesn't say EEG, then why would they believe they know better than the professors that signed off on it?

If the insurer requires a diagnosis, they will look in the DSM and find something they could justify at an inquest. Then they will treat the diagnosis, according to the algorithm, fitted to the patient.

I think doctoring has more defined procedures than engineering. These are not academics, and I think expecting them to be is based on an assumption that 'dr means phd'. It doesn't for medical people.

Re:The psychiatric drug crisis by skunkworks on Saturday September 07, 2013 @11:06PM (#6347642)
No, psychiatry is not a very, very loose and abstract field as much as it's an attempt to wrangle and understand a very, very loose and abstract subject, which is the essential nature of our thoughts and how we actionize them into behavior.

Criticism of its lack of rigor may be fair in many cases, but for you to call it a "sham field" is reactionary and completely inflammatory. Don't backpedal with "I don't want to discredit the entire field" when you're going to lead your comment with, "Good riddance."

I'm a psychiatrist, and I disagree with much of your post. I see below you mentioned going to a psychiatry conference many times, but if it was with the same docs why did you expect a higher level of scientific discourse? It's true that there are crummy psychiatrists, but please don't throw the rest of us under a bus. At our patient conferences, not being to cite articles to back up your treatment plan would be considered an embarrassment.

I think this article puts psychiatry's dilemma into some good perspective: http://www.sciencebasedmedicine.org/dsm-5-and-the-fight-for-...

I do think that it's interesting how people conceive of psychiatry. We cannot really objectively measure or test pain. There's no blood test or scan that confirms it. But as everyone has experienced it, nobody doubts it exists. There's migraine headaches, which are, like psychiatric illness, diagnosed based on history and symptoms. It's pretty uncontroversial. Yet, as everyone believes themselves to be an expert in behavior, if they have not experienced or known someone with mental illness, it's suddenly all invented.

Re:The psychiatric drug crisis by beagle3 on Sunday September 08, 2013 @03:27PM (#6349922)

I think the point stands, since that test is reliant on a patient reporting a sensation of pain. In the same way, psychiatrists must rely on patients expression the emotional problem they're feeling.

Reading that wiki entry, it looks like any objective measurements that arose from dolorimeters are not in active use, because they weren't helpful.

I strongly disagree.

It's an extremely young field, and like Artificial Intelligence, is rapidly growing and seeking to understand the brain (a very, very difficult thing to understand after all).

As evidence of that growth, NIMH just recently abandoned their vast use of an older method to diagnose patients. Until now that was the best thing they had. Fortunately, new technology opens new doors, and they are willing to walk through them. [1]

Psychiatry is a very young field, but it is very necessary.

Positive psychology is also a relatively new field which focuses on making patients happy, rather than diagnosing their problems, which seems to be major nitpick you have with psychiatry. Of course in some cases medicine is required simply due to physical malfunction.

"I do know friends and family who have benefited from psychiatric medications, although that could entirely be due to placebo effect."

It isn't just you. EVERYONE knows people that have benefited from medication. I've seen people go from horrible, twisted states of mind turn into happy, functional people within months by taking medication. The idea that this is just a placebo effect is completely counter-intuitive, for too many reasons to list.

Don't believe for a second the idea that studies or science have anything to do with the author's opinion. People have been saying the same things ever since these medications were first released, without any facts or reasoning to back up their claims.

It isn't a surprise that after 30 years they've been able to come up with a couple of studies to back up what they're saying. What is surprising is that they'd be willing to ignore the tens of thousands of doctors all over the country that have seen these medications work, and the millions of people that have benefited from them. Studies have shown that about 75% of patients treated with antidepressants make a recovery. This is a miracle of modern medicine.

The idea that treating depression is a "loose and abstract field" is absurd. Millions of patients suffer from a range of similar systems. They get treatment, those symptoms are gone. There is nothing abstract about it. Yes, patients react differently to different medications, which is true for thousands of non-psychiatric conditions as well. In these cases, doctors also use trial and error.

Public figures against antidepressants are no better than Christian scientists who encourage patients not to seek treatment for cancer. They're also much more influential: they've persuaded hundred of thousands of people suffering from depression not to seek treatment.

Look, if you have debilitating schizophrenia refractory to any therapy because the demons in your ears tell you the FBI is after you, then the benefits of symptomatic treatment may outweigh whatever unknown side-effects there are.

For the millions of those with 'psychiatric' disorders that are diagnosed using incredibly vague guidelines [0] -- do you ever feel tired? do you ever lose attention? do you ever feel really confident? -- using medications that do not have any observable and immediate symptomatic relief is not worth it. Many of these people have dysfunctions of cognitive processes or issues of their childhood that can be attacked in more conservative ways.

The problem you are pointing out is related to doctors' excessive eagerness to prescribe medicines, not any inherent flaw in the field of psychiatry. This is a problem with the culture among MDs in the US, it is not a global problem of psychiatry.

I've been in first-hand contact with a fair number of doctors, psychiatrists, psychologists and their patients in Scandinavia, and I haven't seen the rampant prescription of drugs to treat vague diagnoses that you describe. If you're in psychotic and in a mental hospital, they'll prescribe drugs, ditto if you have a mood disorder that is severely affecting your functioning. If you have something that reminds of ME or a similar poorly-understood conditions, the meds usually remain off the table and other forms of therapy attempted. Regardless of the situation, if meds are attempted, it's an ongoing experiment to figure out if something works.

Psychiatry would benefit tremendously from a better understanding of brain chemistry. But you're suggeating that we shut down our interim attempts at improving the lives of patients who are suffering greatly today. Psychiatry uses our best guesses yet, and is the best option we have. Its similarities to quack medicine are superficial and incidental.

If the drugs had no effect, then why are people (ab)using drugs like Adderall to improve cognition, etc?

A big problem with trying to make a science out of the brain, is that it can be very unique to the person. For example, in people that are blind since birth, the pathways in the brain that are normally used for visual processing can get re-purposed over a lifetime to be used for other things.

I'd almost say that the brain is sort of like an evolutionary algorithm. Given similar parameters, the results largely resemble each other, but alter things enough and the results can be way off.

Re:The psychiatric drug crisis by WildUtah on Saturday September 07, 2013 @08:39PM (#6347303)
Amphetamine is certainly effective and fairly well understood in its clinical effects. There is no doubt about its effectiveness and principal uses and side effects. (Adderall(^tm) is a brand name for amphetamine.)

Serotonin reuptake inhibitors used for mood management are just a matter of trying them and seeing if you like the way they feel. It's exactly as scientific as drinking liquor or smoking marijuana to see if it makes you more mellow.

But doctors are going around collecting rent on their prescription pads by writing scrips for Paxil and Prozac and the like as if they were technical and carefully calibrated professional tools that required twelve years of college and med school and internships and apprenticeships to master and administer. They're doing all that training and then providing the same service as witch doctors -- but for a lot more money.

You say the same thing that doctors say about SSRIs: is certainly effective and fairly well understood in its clinical effects.

Yeah, of course we see the effects, but we still don't really know how exactly it works. For example, no one can tell for sure why Dextroamphetamine and levoamphetamine have different effects (the former is a brain stimulant, while the latter affects mostly the body). Adderall is mostly dextroamphetamine, by the way.

You're making an assumption here -- that people's trust in, and use of, drugs argues that it's not a mere placebo effect. But there are any number of accounts of people persuading themselves that a drug is reliable, for a drug that is in fact a placebo. In fact, that's how the placebo effect is defined.

The only way to sort out these issues is with a double-blind prospective trial. Unfortunately, such trials are nearly nonexistent for this class of drugs, and those trials that have been conducted, are often run badly or published in very selective ways, creating the impression that the drugs are more effective than they really are.

Whoa, wait a second here. Your reference article is arguing that there isn't any difference between these drugs and placebos, so by definition it was a "placebo controlled trial". To say that "double-blind prospective trials are nearly non-existent" is very wrong. Unless you are referring to very old psychiatric drugs, most of them have gone through such trials.

There was a lot of disagreement about the paper you referenced. CNS drug are notoriously hard to get positive clinical trial data for. The reasons are: (1) placebo effect is notoriously difficult to control for in psychiatric trials, (2) the clinical trial endpoints are very blunt measures of efficacy.

But you know what? That's the best we have right now. There certainly is a strong requirement for efficacy in psychiatric drugs as evidenced by how many have failed to get approved by the FDA.

The sad thing is that most big drug companies have completely pulled out of doing R&D for new CNS drugs. They are just too hard to get approved. The end result is that patients with psychiatric illnesses will end up with fewer treatments options unless this changes.

Re:The psychiatric drug crisis by lutusp on Sunday September 08, 2013 @01:31AM (#6347927)
> To say that "double-blind prospective trials are nearly non-existent" is very wrong.

You need to read each word and think about it. In a prospective trial, subjects are chosen in advance, they aren't drawn from an existing population of people who have already decided to seek psychological help.

A "double-blind, prospective trial" would have to sign people up from a cross-section of the population who have no interest in, or association with, psychological treatments. Then they would be divided into two groups. One group would receive the drug under test, the other would receive a placebo. And the trial would have to be designed so that the two groups wold not be able to tell to which group they belonged. Unfortunately, about the drugs under test, most of them have side effects, which means the subjects aren't blinded (the placebo group have no problem realizing who they are).

Even will all its defects and shortcomings, what I have just described is unheard of in psychological testing.

> Unless you are referring to very old psychiatric drugs, most of them have gone through such trials.

Absolutely false. The kind of design I am describing is simply unheard of. Most trials are of self-selected psychological treatment clients, and it's not uncommon for the "control group" to be what are euphemistically called "no-treatment controls". Guess what that means -- it means the experimental group is compared to people who are told to go home with no treatment and no sham treatment.

> There was a lot of disagreement about the paper you referenced.

Yes, of course -- and that's the way it should be. But there have been enough similar studies and meta-analyses that the outcome is not in question.

> But you know what? That's the best we have right now.

Different topic.

> There certainly is a strong requirement for efficacy in psychiatric drugs as evidenced by how many have failed to get approved by the FDA.

Most of the drugs that just were proven ineffective were not ever tested for efficacy as psychological drugs, they were prescribed off-label -- they were originally approved for some other purpose.

> The end result is that patients with psychiatric illnesses will end up with fewer treatments options unless this changes.

If the treatments were effective, that would be a shame. But they aren't, so it isn't.

Re:The psychiatric drug crisis by cdjk on Sunday September 08, 2013 @01:57AM (#6347973)
Prospective study was probably not the correct term, since that's an epidemiological study. "Placebo controlled study" is probably a better term. And a placebo controlled study is the best evidence for a medical treatment - doing epidemiological studies to determine medication effectiveness doesn't seem right.

Consider an SSRI study for depression. I want to know if someone who is depressed and takes it does better thank someone who is depressed and doesn't take it, or takes a different drug. I don't care what it does in a healthy population, since they probably won't be taking it. I mean, the effects of SSRIs in healthy individuals is an interesting topic, but not relevant if I'm investigating depression treatments.

Re:The psychiatric drug crisis by lutusp on Sunday September 08, 2013 @04:14AM (#6348158)
> And a placebo controlled study is the best evidence for a medical treatment ...

Yes, and with respect to the drugs we're talking about, subsequent meta-analyses show that the original studies were all biased in favor of their sponsors and all the drugs produce the same results, which argues for a massive placebo effect.

For years, studies were published that appeared to support various drug approaches to mental illness, but those studies have been invalidated by more careful analysis that included (as just one well-known example) unpublished studies that came to conclusions not favorable to the drug companies' outlook.

> Consider an SSRI study for depression.

Yes, let's do that. As things stand right now, studies of drugs that increase serotonin levels show the same effects as those drugs that decrease serotonin levels. This causes open-minded scientists to doubt the efficacy of this entire approach.

Reference: http://www.newyorker.com/online/blogs/elements/2013/09/psych...

Quote: "While S.S.R.I.s surely alter serotonin metabolism, those changes do not explain why the drugs work, nor do they explain why they have proven to be no more effective than placebos in clinical trials."

> I mean, the effects of SSRIs in healthy individuals is an interesting topic, but not relevant if I'm investigating depression treatments.

Such studies -- with the diagnosed depressed -- show no clinically significant result that can distinguish the outcome from the placebo effect. Those are the facts.

Re:The psychiatric drug crisis by pyre on Sunday September 08, 2013 @11:18AM (#6348950)
If SSRIs are no more effective than placebo, then:

The placebo effect. Surely you don't think everyone has the same placebo effect? Also, you're not describing the same study with the same participants and different drugs, you're describing different studies, different subjects, and different drugs -- all of which can change the outcome.

> * Why does increasing the dose of a specific SSRI have an increased effect?

The placebo effect. If people believe that a placebo is working, then more placebo produces more illusion.

Also, your use of the term "increased effect" is misleading. The largest doses show an effect, smaller doses show no effect. One theory about that is that the large-dose drug's side effects alert the subjects that they're not in the control group. A proposal has been made to create "active" placebos, placebos that mimic the side effects of the drug under test but not the property under test. This idea hasn't been tried yet.

> Is it not possible that the real reason that SSRIs might be no more effective than placebo in clinical trials is that we don't quite understand the reasons that they work yet?

You're overlooking the fact that placebos produce the same effects as the drugs under test. Our understanding or not understanding isn't an issue, because they've been demonstrated to be indistinguishable from a sugar pill.

And our not having a mechanism is definitely a criticism of this kind of treatment -- it would be like administering a mystery drug that proves essential to health, then deciding to increase the dosage, without understanding that the mystery drug is fatal in large doses (like vitamin A).

Wait a second, "prospective" trial does not mean that you draw patients from a pool who have no interest in treatment. Prospective simply means you have decided what the endpoints will be before the trial begins.

The inverse of a prospective trial is a retrospective trial where you have a set of data and you go looking for signals.

Then it's a good thing that I never said or implied that. The subjects must be drawn from a uniform population, not from a population that have already come forward for treatment -- otherwise the result is biased by the experimental population at the outset.

> Prospective simply means you have decided what the endpoints will be before the trial begins.

No, it means the experimental design doesn't recruit from a pre-existing population of subjects with a history or established preferences, instead you choose random subjects from the population at large.

> The inverse of a prospective trial is a retrospective trial where you have a set of data and you go looking for signals.

There's nothing stopping you from actually learning what these terms mean. A prospective study recruits subjects from the population at large, people with no particular interest in, or knowledge of, the topic being studied. A retrospective study relies on self-selected subjects, people who are already engaged with what you want to study.

For example, let's say I want to study the link between daily vitamin use and intelligence -- do people who take a daily vitamin become more intelligent as a result?

I begin to design a study. Shall I enlist people who already take a daily vitamin (retrospective), or do I enlist people with no interest in the issue, divide them into two groups, make one of the two groups take a daily vitamin, and make the other group take a placebo (prospective)?

See the difference? In the retrospective, any conclusion I make may result from a confusion of cause and effect -- for example, if the vitamin-takers turn out to be more intelligent, that might result from a factor like intelligent people taking a vitamin because of their increased awareness of health issues, in other words, it might be an effect, not a cause.

The prospective experimental and control groups, one of which got a vitamin, and the other which got a placebo, is much more likely to produce a meaningful result.

Re:The psychiatric drug crisis by refurb on Sunday September 08, 2013 @09:17PM (#6351326)
Well you did a much better job describing how you define retrospective vs. prospective trial design. I still think the way you are defining it is not accurate, since retrospective trial designs have nothing to do with self-selection. That is a separate matter. All retrospective means is "looks back in time" at data that has already been collected.

However, you argument stills doesn't hold much water. How can a psychiatric drug be used retrospectively unless it has already been approved for use? If you're complaining about trial data on off-label use, then I won't argue, but the FDA does not accept retrospective trials to support drug approval.

Placebo effect is certainly an effect. But the claim is not that the drugs don't have an effect (though it's true, some work no more effective than a placebo), but that we have no sound explanation for their effects.

Do you have a citation for this? What drugs on the market today are "no more effective than placebo?"

There are many studies. Here's one:

http://jama.jamanetwork.com/article.aspx?articleid=185157

This study found that SSRIs provided little to no benefit over placebo for patients suffering from mild to moderate depression. SSRIs did provide a benefit to patients suffering from severe depression.

This raises the question, how many of the 30+ million Americans currently prescribed anti-depressants actually suffer from severe depression and benefit from the drugs? How many are taking it unnecessarily, subjecting themselves to unintended side effects and eventual withdrawal symptoms.

Let's play the devil's advocate here... I've known people who have lost their marbles once they stopped taking their meds. Are we rally saying that their grip on sanity was a placebo effect? Or are we saying that we're just treating the symptom? If it's just the symptom, who cares, as long as the drugs help people?

For context, I'm not on any psychiatric drugs, have never been on any, and think they're largely being abused by American society. But the extreme cases suggest to me that they have a use.

This and similar comments in this thread is a plausible guess, but it's fascinating how so many of the computer programmers here are domain experts that have thought of things that all the psychiatrists in the world haven't thought of yet. All psychiatrists have six years of basic scientific education before starting their specialization. They're not the unwashed idiots that people here seem to think.

"Discontinuation syndrome," AKA withdrawal: http://en.wikipedia.org/wiki/SSRI_discontinuation_syndrome

I'm a big "weird crime" geek and pretty much every single one of them, if you dig deep enough (and quick enough--I've seen news articles "cleaned up" after-the-fact to remove references about medications. Doesn't need to be a conspiracy when we have HIPAA), you find that the perpetrator had either been prescribed new meds/upped dosage in the past week or discontinued suddenly. Also, it's a little bit like a miscarriage--if you talk about it even a little, the private stories come out of the woodwork. Some tragedies, some "holy cow, am I glad I figured out what made me want to buy a gun." What kills me is not knowing how many suicides could have been avoided. And that the word isn't out yet, how many more will we see?

I am seriously a little terrified about a mass shortage of these medications (SSRIs and antipsychotics aren't the only medications that can cause akathisia, delusion, homicidal/suicidal ideation...we've got Larium, ADHD meds, I even just read about a weight loss drug with suicidal ideation as a side effect...banned in Europe but A-OK in the US). How irresponsible if pharmaceutical companies just cut these drugs out without giving their patients a method of safely withdrawing from them... Dig around for withdrawal-induced crimes (especially at the local level; more data there), and you'll see that it's actually murderous. The least they can do is research which genotypes are most susceptible to dangerous side effects (for example, is it possible that people with the MTHFR gene mutation or other characteristics are hit with serious withdrawal symptoms?) to share with prescribing doctors.

> If it's just the symptom, who cares, as long as the drugs help people?

Because for many, these symptoms are not adequately addressed through more conservative means. There are numerous ways to attack an unusual disposition that do not involve medication -- exercising, weight loss, meditation, psychotherapy, cognitive behavioral therapy, rectifying family issues, finding a job. Many of these options are not adequately pursued. I have never seen a psychiatrist refer a patient to see a psychologist or a cognitive behavioral therapist, and they have no incentive to really.

Re:The psychiatric drug crisis by derefr on Saturday September 07, 2013 @10:59PM (#6347620)
On the other hand, where I live (a non-US country with public healthcare), you don't get in contact with a psychiatrist directly; you get referred to one from a therapist. The therapist decides which kind of treatment of your symptoms is best, where one of their options is to pass you off to a psychiatrist (who the therapist thinks of as "the guy who will mostly think of this in terms of prescribing medications.") Even when the therapist thinks medication is a good treatment regimen, they usually suggest combining it various forms of talk-therapy (in other words, to keep seeing them, as well as seeing the psychiatrist.) Those are some much more neatly-aligned incentives, I think.

---

I have to say, though, as a separate issue: neuroaffective medications of all kinds (whether for chemical imbalances, or hormonal imbalances, or pain-management, etc.) are basically like crutches.

Your problem might not be "just" a chemical imbalance, just like your problem might not be "just" pain. But even if the cause is external, and the "true solution" is external, the symptoms the external problem is causing in you might be too debilitating for you to pursue the external solution on your own, while you're still afflicted. That's when you need a crutch.

If you break your leg, walking on it enough to get it to heal is usually far too painful to do all on your own. So, you get crutches. Now you can get some support to lessen the pain, while still walking on it to help it heal. If you lost your job while you were in the hospital for the leg-break, the crutch can let you go back to work before you otherwise would, which can give you the motivation to keep pushing yourself to heal, rather than just sitting around. Once your leg has healed, you don't need the crutch.

If you're clinically depressed, going out and doing things you'd otherwise enjoy is hard. SSRIs and the like are a crutch that let you feel less pessimistic about your situation, so you can pursue real sources of happiness (getting a better job, finding a relationship, etc.) Once you've done those things, you might not need the crutch.

Sometimes, though, we need crutches for life. Once you're old enough to need a cane or a walker, you're never going to not need a cane or a walker. Some people are born with conditions that put them in a wheelchair for their entire lives. If your problem is inherent to your physiology, there's no external problem to solve--so you'll always need the crutch.

---

Here's the odd thing about neurotransmitter imbalances, though. I asked a psychiatrist friend of mine about whether, generally, his patients have obvious problems in their lives that could be possible causes of their symptoms, or whether they more often say things like "everything's great so I don't see why I'm so--". He said it was overwhelmingly the latter.

My pure guess to explain this data, is that something happened to our brain chemistry that paralleled the rise of near-/farsightedness as a genetic trait. After the rise of agriculture, sharp near/far vision stopped being something we had natural selection pressuring us to keep--and, unlike traits like height, it's hard to tell how well your partner can see, so it wasn't sexually selected, either. So the likelihood of your vision staying perfectly "in tune" with the reference point became pretty much random chance, with near-/far-sighted people mating with other near-/far-sighted people with no concern for the consequences.

So, just as our eyes have to be tuned to a certain reference point to work optimally, so do our neurotransmitter levels. And just like people don't much care if their partner can see well, people don't much care if their partner has strange moods sometimes (--in fact, some might prefer partners with a certain demeanor.) So we've let genetic drift and random crossovers take the place of selective pressure in determining our brain chemistry. A lot more people are born needing figurative wheelchairs than find themselves needing figurative crutches.

But a wheelchair is a bad metaphor, here, isn't it? A wheelchair is for someone who can't walk at all without it. Whereas, being slightly off your reference point, and using something to bring you back in line? Why, that's a lot more like wearing glasses!

Looks like that's exactly what you want to do. Luckily, you're not doing a good job of it.

Yes, and until then what? Do nothing and let the suffers suffer? Per your own admission many people are helped. Perhaps that should be your clue to lay off the righteous indignation at lack of precision. Yes, we all want something that works in all cases, but in the mean time we should use something that works occasionally.

That's what research is for and is doing, but in the meantime what you're suggesting is that we sit on the sidelines and watch those that need help suffer because what we know isn't up to your standard? So we're going to take your anecdotal experiences in the psychiatric community about how psychiatry is anecdotal and is thus largely discredited?

Would you really be willing to let millions of people suffer because of that hypocrisy? Very frightening.

Re:The psychiatric drug crisis by DannyBee on Sunday September 08, 2013 @02:13AM (#6347997)
I used to think much the same thing. I have, however, had the wonderful experience of being treated (for ADHD) by two very science oriented psychiatrists.

They know the research articles cold, suggest approaches based on actual research, can explain the best scientific understanding of why something should work, and when it doesn't, why that theory may be wrong, etc.

Now, as for " What needs to happen first is that we need to attain a much deeper understanding of how the brain works on the low and high levels, mechanically and abstractly."

I couldn't more strongly disagree. What you say could be applied to every area of medicine. We have been very wrong in very many fields about very many causes of very many diseases.

We only gain understand through trying and failing, and trying and succeeding. Sitting around waiting for scientific knowledge to magically increase through some unspecified process will do nothing.

If you want to argue psychiatrists are overconfident and usually wrong, that's one thing. If you want to argue that the diagnosis criteria are essentially vague bullshit that reads like the stuff they used to use to convict people of being witches, i'm right there with you. But you seem to be arguing we should stop trying with medications until we understand things better.

If we did that, we should stop roughly all modern medication, because in large part, we only know it works, not why or how, at any real level. We irradiate cells to try to solve cancer. This is basically at the level of using leeches.

We have theories. People are trying these theories out on real live people through making test medications, performing trials and treatments. Sometimes they pan out, sometimes they don't.

Sitting around doing MRI imaging studies (and any other kind of study you can think of) of the brains of various mentally ill people has been done, and the results analyzed. It has not helped.

So let's start simple: What exact process would you use to increase knowledge to the point you suggest?

Past that, if your real argument is that more conservative approaches should be favored over medication first, well, the problem there is simple at it's core:

Nobody is willing to pay for it.

Insurance companies are happy to cover a pill at 10 bucks a month for months.

Most people can't get outpatient CBT/DBT except at significant out of pocket cost.

So the fact that you have plenty of psychiatrists willing to sit around and prescribe med after med is partially an artifact of "that is what they can do for their patients".

First, you're very lucky! From what I understand, those psychiatrists are not only expensive (usually they are not on insurance plans), but also hard even to schedule (as they are rare, and in high demand)

Slightly OT, but were you diagnosed as a child or as an adult? If the former, did your treatments change as you grew older? If the latter, what was your impetus in getting diagnosed/treated?

Re:The psychiatric drug crisis by DannyBee on Sunday September 08, 2013 @07:02PM (#6350840)
It is true my psychiatrists are not on insurance plans. This is a larger problem with how mental illness treatment is funded/supported.

I was diagnosed as a child about 27 years ago (IE well before the current "popularity").

My treatments did change. I learned to cope with some aspects, the medications I used changed (I am on a non-stimulant now, Straterra, that works as well as my stimulants did).

Besides being able to be more introspective and self-aware as I got older, I also chose a path that would set me up for success.

I have a job that has multiple roles, and essentially requires me to pay short amounts of attention to a large number of things at once, which is somewhat ideal for my ADHD. The things that require longer amounts of focus tend to be lower priority.

That's interesting - thanks for sharing. IIRC Strattera is relatively new; I wonder if the drugs themselves are getting more effective, or if the most effective drug for a person changes over time based on physiological changes or external factors.

I don't have any personal experience to compare it with, but of my friends who have been treated for ADHD for more than 15 years, it seems all have had to switch medications multiple times.

I don't see your email address on your profile, but mine is my username at gmail - mind dropping me a line?

"That's interesting - thanks for sharing. IIRC Strattera is relatively new; I wonder if the drugs themselves are getting more effective, or if the most effective drug for a person changes over time based on physiological changes or external factors."

Yes, Straterra is relatively new. I became immune to ritalin (well, roughly) after taking it for so many years, and Adderall, even in the XR version, started becoming less and less effective for me. This is apparently normal, and medication switching is common over long term treatment.

My doctor said she could up the dosage, but that she'd rather try Stratterra first, given the advantages of that vs high-dose stimulants

Note that 20 years ago, the common viewpoint was that adult adhd did not exist, that it simply "wore off" as you got older.

Straterra has worked fine for years so far, and i have not seen any of the gradual reduction effect that was completely obvious in all the stimulants over time.

I'll drop you a line.
