My parents are 88yrs old. Stepfather has Parkinson's Disease and beginning of dementia. It's just him and Mom in CA. He is a retired marine LtCol. and gets 3 hours weekday mornings caregiver. However that's 3 hours out of 24 hours. Pops is condition causes him to want to be busy so he tends to want to work on electronic things unplugging everything and wanting to take things apart and his dementia is causing hallucinations. His mind often seems intact as he still tracks with conversations most of the time.
Mom is tired and stressed and months older than him. She is now limping and has to take anxiety pills.
