Could my memory loss really be depression?updated: Tue Mar 29 2011 18:27:00

I am having significant memory problems that my M.D. thinks are due to depression, but I wonder if such severe problems can be accounted for by depression. I have had dysthymia my whole life. I admit I have a lot of stress in my life and may even be more depressed than I have been in the past, but I have never had these problems before. Here are some examples of things I forget on a daily basis (multiple times a day, actually) : not knowing why I'm in the car driving, not able to remember longtime friends' names, my dog's name, can't remember the names of common objects, putting keys, laundry, etc. in the refrigerator. This is affecting my professional and personal life. Could this really be just depression?

Can depression cause memory loss?updated: Tue Dec 15 2009 12:09:00

My husband, age 39, was diagnosed with manic depression/bipolar disorder approximately two years ago. He suffers from recurrent bouts of depression and is currently in a depressive phase. He does not have very many manic phases at all. His short-term memory is getting progressively worse. Lately he cannot seem to remember how to get to places that he had just visited two or three days before. This has happened three times in the past week alone. Is there a correlation between recurrent bouts of depression and memory loss? I would question the medications as a factor, but he has not changed meds in many months and the episodes of memory loss have been in recent weeks. I would appreciate any information you can give me, as the primary caregiver you can imagine that this whole ordeal is very difficult.
