I don't know if my husband may have mpd or not. There has been a few times within this year that my husband would go through this" personality change". It starts when i put to much stress on him when we argue. Its like one minute he's himself then the next out of the blue he goes into this daze. Then his personality changes to really sweet or really aggressive. His personality would change like 2 of three times. When he is coming out of it, its like he goes through a seizure...well kinda. He would have no memory of anything that happened except for maybe when the argument first started. He thought he was sleeping. Could anyone tell me if this could be the onset of mpd or something else????. There also has been times when he tried to rape me or hurt me lol. Its really weird. I have ptsd so I worry a little.
