My mom is 89 yoa, with medium stage dementia. She knows us and our names. She has anxiety for years. Took different meds for agitation, nervous, anxiety. Now on zyprexa And klonopin First 3 weeks she was fabulous!!!! Then slow decline and 2 months later: shuffling gait, shakes legs, drooling, sleep all day or unable to keep eyes open, slur speech, hand tremors, jaw tremor. Is there a test to determine if too much zyprexa? Over medicated vs an advancement in dementia (which nursing home is stating). I think over medicated. Started reducing dosage of zyprexa this week.
