My father has Parkinsons. He lives in Holland, and has had very good care so far. Recently he was admitted for assessment, as his condition was deteriorating and he was having many falls. He also has the form of dementia associated with Parkinsons disease.
While in the hospital, he was prescribed an antipsychotic specifically to keep him from getting out of bed and wandering. The guidelines in Holland are the same as they are here - these drugs should only be prescribed in elderly people with dementia if they are aggressive, violent and in danger of harming themselves. They pose a considerable health risk to elderly people, are only effective in 20% of people and then for no longer than 6 weeks.
My father was given them to keep him quiet. He gets irritable, but is never violent - just restless. He can be distracted. The people looking after him knew what they were dealing with and were supposed to be specialists.
My DM is pursuing this with the hospital, she discharged him as soon as she found out, got medical advice about stopping the antipsychotics and followed it - he is now off them. She will be putting in an official complaint.
I am angry and sad - the relationship of trust between my parents and the medical profession is now lost. My father will now not ever go into a nursing home, which may well be the best option for him, because my mother will never trust anyone with him ever again.
