Dad is 6 yrs. post stroke. He was fine for 3 months then spiraled into deep depression. We tried all kinds of pills, counseling, but nothing. Now he is at a new stage of combative meanness. He doesn't care a hoot about his hygiene, he believes my mom is trying to poison his food, he questions everything and believes nothing, We need him to get to dr's appts. but he refuses, he's hiding pills and saying he took them, he has been physical once w/ mom, otherwise he's just killing her w/ irrational, terrible words.
I am not a doc but one thing I know for sure is that dementia presents itself in so many ways and we think that the person is being mean when they are really demented. Mad as a hatter. They end up dangerous to themselves and to everyone around them.
If he slips a wheel again, by all means call 911 and save everybody involved but know that this is probably some kind of dementia caused by stroke or ?
I used Namenda on my mom who was mean as a snake when I intervened to be her caregiver. That med worked so well and it got her to not be so mean and abusive.
Good luck and know that you have a lot of support here on this site. Vent and live. It really works.
