Just do a Google search for "mania grey matter" or "bipolar grey matter" and you'll find lots about how episodes cause the loss of grey matter, the stuff our brain is made of.

Then search for "bipolar neuroprotective" for articles about how lithium protects the brain. That's just lithium but maybe some more digging will turn up something about the benefits of other meds.

I think my memory issues are a result of my depression, also based on what my doctors have told me over the years, and I'm hoping that once I find a combo that works I'll at least stop the loss of memory.

Having been on meds for years, I haven't lost any of my intelligence though.

I hope you find information that helps you blue.
