Akesh,

Not much to add. The Syndopa and other medication I have not heard of.

Ayurcedic medicine called for tummeric and black pepper. Still a good combination.

One cognitive issues, my mind was wondering more than I wished. I do have some issue recalling words and location, but when I had a full blood panel done it was obvious I was lacking Vitamin D. So I am taking 4000IU daily, and it seems to help (I'm still working -- Electronic Engineer; Oh company CEO is a well known native of India, and does his daily Yoga excercises).

Where in India is your father located?
