I am 23 year old guy from a metropolitan South Indian city. I was working in a startup for more than a year after my Engineering graduation until I resigned a couple of month ago. I had quite a problems in remembering things, dates, tasks etc., that was delegated to me due to which I was doing poorly in my job. The same problems effected my life as I was not able to concentrate on anything. I am an introvert person and I have few friends with whom I shared this problem. They tried to console but they could not give a solution. In 2011, on a roadtrip, I met with an accident in National Highways but got away with small bruises. I sometimes doubt whether I am having these problems due to the accident because I have NO memory of how that accident happened and I fell down and fainted (Even I did not feel any pain when I met with the accident) Only I could remember was that I got up myself after few minutes (It was night time so no one was around to help that time). I am afraid to open this up to my parents as I feel they will get worried too much. When I go out sometimes I get panicked as to where I am and how I ended up in that place. As a result, I always try to be aloof as much as possible. Also, I had a great vocabulary since childhood but I find it difficult to converse with anyone now a days. I compare these symptoms to Dementia, Alzheimers and I get more confused.
