I am 61 and for the last 30 yrs I have had recurring instantaneous mental spells in which I experience a strong sense of reliving a memory (a different memory each time) followed by a strong mental euphoria followed by a deep sense of sadness combined with a sick feeling in my stomach like I may vomit, but i never have. The whole episode takes maybe 5 seconds and it is like a computer crashing and it takes about another 30 seconds to totally recover. I do not loose consciousness and have had one when driving (able to keep driving safely but a little disoriented) a few times when talking (disoriented and not able to remember the topic) and 3 times running ( had to stop for a minute or two to get reoriented) but most often it is just when I am going about life (recently had a couple in the shower in the morning, and they seem to happen before midday) They started in 1982 following the suicide death of my dad and peaked during a nine year work assignment away from my family. At that time there were days that I would have as many as 6 spells in one day. I have gone many months without a spell and recently they are sporadic and I may average one a month. So the spells could be stress related. I am being treated for depression and have taken Zoloft or pristiq for 20 yrs. currently I take 100mg of pristiq but that helps but has been less effective in the last year or so and I intend to talk to my doc about trying something new. In the last year or so I also have been dealing with increased long term and short memory loss. A MRI from a few years ago show small 'white spots' throughout my brain that the doc says a dead cells but don't have a cause. I had one suspected TIA about 10 years ago. Any thoughts about what could be the cause of the spells and my increased memory loss and could some of the things I describe by connected. Thanks so much for your time
