Memory Loss and Forgetfulness
Is there anyone here with any experience dealing with difficulty remembering recently past events, and any suggested courses of action, causes, or effective treatments?
I have long suffered from very poor short-term memory. I'll set out in my car, only to forget 5 minutes later where I was intending to go, sometimes driving for 20 minutes in an irrelevant direction. I would visit friends over the weekend, and have little recollection of the weekend by the following Monday. Then I'd visit the same friend a few weeks later, suddenly remember what I did the last time I saw her, only to forget the time in between. I frequently have periods of up to 4 hours where I sort of blank out, suddenly realize several hours have passed with no rememberance of what I did during that time. I have for years attributed these memory lapses to purely psychological causes - I have a relatively faint but discernable DID (dissociative identity, a.k.a. multiple personality) disorder, along with PTSD and mild depression. But I was still shocked to see the results of a recent formal psychiatric evaluation that showed my memory disturbances were just about off the scale, even worse than average DID patients. My scores for everything else were much closer to the normal range, albeit still elevated for most categories. So I'm beginning to suspect there may be something else going on here, a physical condition. It probably doesn't help that I've used MDMA (ecstacy) in the past, which has been linked to killing brain cells.
Should I be seeing a neurologist, or some other type of doctor, about this? What are other causes of memory loss that would affect an otherwise reasonably healthy 39yo male? This is becoming almost unmanageable and a huge disruption to almost every aspect of my life and I'm at a loss as to what to do. My GP doesn't seem to be all that familiar with these conditions.
Thanks in advance for any help.
