What are some non-medical treatments for parkinson disease dementia, coping mechanism?

Sort Of. At this time there are no medications specifically indicated for parkinson's dementia. I have used the current medications that are used for alzheimer's dementia as these are available. Coping mechanisms are the same for all dementia. Treat the brain as though it is a muscle and keep it exercised regularly. Stimulation like reading, playing cards, puzzles, and games. Also, physical exercise.
Dementia. Alleviate stress, balances diet, ti chi, yoga, stationary bike riding, calming teas, reading about the condition helps the care giver cope which in turn helps the patient.Join a support group.
