Thanks for this thread, blue!

It's my understaning that it's natural for us to lose some IQ points as we age, even without meds or mental illness.

That said, I have found my cognitive abilities fluctuate, sometimes greatly. This was true long before taking any meds.

I have read, repeatedly, we'd benefit from:

Fish oil
Stimulation, even solving puzzles, etc.
Exercise - increases circulation.

These are some of the basic, as I understand this.
