Went to sleep two weeks ago and woke up complete personality change short-term memory is gone I struggle with doing any kind of tasks and completing it and that's only if I can remember to do the task not safe to drive anymore having hard time keeping up with financial responsibilities and I talk very fast and constantly the speed of my speech has slowed because I slur my words and I cannot get my words out talking fast so I kind of talk like a robot I am aware of how I sound and look to others and I'm profoundly embarrassed my cat scan was clear did some memory test we'll get the results next week nothing has improved in the last two weeks I abused My Friends by talking constantly and for way too long I always apologize and they do know this incident has happened to me has anyone experienced this with their loved one
