I’ve yet to hear someone describe ADHD in the third way and this thread is the only time I’ve seen folks ever mention it.
Someone with a more neuro-typical brain might not be thrilled about mundane experiences, but can still tolerate the situation.
In an ADHD brain, mundane experiences over-engage areas of the brain associated with physical/emotional distress (amygdala). ADHD brains are also impacted by abnormal dopamine regulation, which affects the reward cycle for accomplishing mundane things.
Here are some comics to help contextualize: https://twitter.com/adhd_alien/status/1182670794633207813
I think one of the reasons so many people showed up to post about ADHD here is this, from the OP:
> Although, it seems quite trivial, for me this is a huge live hurdle
My school grades as a kid were fine, but I was studying at least 2 different books at same time because after a single paragraph it was already "boring as hell", even being genuinely intrigued by the problem and the possible outcomes. So to study simple math, multiplication for instance, I had a science magazine open beside to constantly remember the outcomes of studying math (understand astrophysics that apparently is cool), at same time I was studying history with a history book and the cover of Red Alert 2 to remember what can happen if don't understand the outcomes of a possible domination by a authoritarian leader.
So 4 fucking things at same time. All of that to just get a C or B- grade.
I was amazed recently to be able to do just few tasks properly done and managing to rest and remember to eat. Few properly done tasks was usually a result of super/hyperfocus where the toll later was extremely high, like eating lots of garbage food to compensate the lack of food during the previous hours, sometimes as high as 20 straight hours.
1) Hyperfocus for hours at a time, often forgetting about physical needs like food/drink/bathroom.
2) Extreme trouble getting started on a task (inability to overcome inertia) and constant distraction once started.
3) Switching hobbies, jobs, roles, spouses, etc because the initial stimulation of something new is more rewarding than old interests.
ADHD's symptoms are caused by a deficiency in reward dopamine systems. The "craving" for dopamine is stronger in ADHD brains, which is why impulsive/risky behaviors are common in people with ADHD.
Talk to a medical professional if that resonates. Therapy is also helpful, since the behaviors associated with ADHD can lead to built-up shame / self-doubt.
Medication helps (for me, it was like putting on glasses for the first time), but re-modeling behavior and self-image were equally important for me.
