Probably since I was 25 I am 32 currently it just got progressively worse. I have had a few seizures so memory loss might be due to that. When I exersize my memory seems to be a lot clearer. The meds make me feel Sudated and cause memory loss it's like being in a fog. I have had a lot of traumatic events in a short amount of time.. Which may have triggered it, I am thinking memory loss is a sort of protection to prevent major overload of stress on the brain. But it's pretty miserable having no direction that's how I feel. Hopefully something changes soon ...😔
