He was diagnosed with dementia a year ago last month.  His dementia has progressed rapidly in this past year.  I believe that the Ativan caused his dementia.  At this point he is thoroughly out of control.  We had to have him hospitalized in a psychiatric unit to detox him from Ativan, Seroquel and Depakote.  The last two drugs have only been prescribed since Feb. this year.  He was having periods of extreme agitation and aggressiveness that led to his hospitalization.  He was released last Friday after spending 8 days in the psychiatric unit.  His verbal abuse and threatening of harm to my mother has increased ten fold.  The slightest thing agitates him.  For the past few days I have spent 8 plus hours at there house making sure he gets his proper meds and that he eats.  My mother is overwhelmed and too upset to do these things for him anymore.  There are some family issues that have caused this situation to spiral out of control.  At this point I truly believe that a nursing home is no longer just an option it is imperative.  My last question posted here was in February and I am thankful for the feedback I received.  Any feedback on this current situation will be appreciated.
