Hi alphaomega. I recently spoke with a neuropsychologist about being tested for some things. I asked her how long before the brain returns to normal and she said for a long term chronic alcoholic, after two years you are back at your baseline provided you quit before 50 years of age. That's what she said, and she's a Dr, hope that helps. After fifty I don't know how long. I was asking about other things not PAWS but I imagine she meant all things affected by alcohol as far as the brain goes.
