I have a theory, though. Neuroplasticity is the
brain learning new pathways, because the old ones no longer work.
Aricept was oddly enough like turning up the water so you'll have more pressure in the garden hose. I knew the holes were there, but I was able to think around them more easily. So perhaps Aricept helped my brain to learn new pathways.
At any rate, I would wait to fill my prescription until I could feel my brain reverting to its old foggy ways.
