The fact that he has Parkinson's and "dementia" may lead one to take a close hard look at his meds. Generally Parkinson's patients are on Sinemet dopaminergic agonist therapy, dementia patients are on acetylcholinesterase inhibitors, and severe dementia patients are usually on neuroleptics.
This is the wonderful world of polypharmacy we live in, along with Physicians diagnosing "dementia" as if they were 3rd year medical students.
Parkinson's Disease > 2 years followed by the emergence of dementia = Parkinsons Disease Dementia. Parkinsonian symptoms emerging closely spaced in time with dementia = Dementia with Lewy bodies.
Either dementia patient generally should not receive neuroletpics, but we all know they do.
Anything like this based on this type of patient I assume is it a medication adverse event until proven otherwise, unless there are focal neurological signs present.
Did he recently start an acetylcholinesterase inhibitor for dementia, or did he recently discontinue one abruptly? Or was he on an antipsychotic?
