Do try to keep in mind a lot of the world had a bit of a social crash and reboot during the pandemic

Of course stay aware of your health, but allow some wiggle room for that when it comes to social concerns

If you have young kids.. that's it. Apparently it gets better. It did for me, had a big dip then came up smarter. Now with our third in the "terrible two" phase I'm in a terrible dip. This time next year I'll be back to my horrific smart, egotistical and demanding self :-)

Interesting. I'd never heard that that could be a cause of cognitive decline.

In any case, no, I have teens. I've been wondering if maybe I caught covid without knowing it (asymptomatic) and this is brain fog.

Something like this turned out to be Lyme for me. Good luck.

Thankfully not a thing in my country :)

Encouraging to hear it gets better, I have a 13 month old and feeling quite slow witted lately.

This could be beginning of alzheimer's. Alzheimer's, like balding, is too often put away like an unpleasant thought until it's really too late to do anything about it. There is an obvious advice here of going to a good doc and having your lifestyle in order, but barring that there really is no sufficiently good treatment yet which is validated by large clinical trials.

But as a last resort, I'd check these papers and search for a doctor or an acquaintance who could help you make sense of the current cutting-edge research and possibly apply it for your case:

Do not go gentle into that good night.

We do have dementia in the family (grandmother and aunt), but they both got it after 70. I'm only 40.

I appreciate those links; thank you so much for that. I'll read them, and I'll see a doctor.

See a doc mate. Fix sleep, stress, nutrition, exercise.
