My father has vascular dementia and he was discharged from the nursing home due to aggression. Where can we turn?

He should go to a geriatric psychiatric facility for as long as it takes to get him under control (many others on the forum have had to take this step). If he is still in the nursing home I would refuse to bring him home and push them to help you find him the help he needs.

We need more background information about your father's current living situation since he was discharged from the nursing home and health status regarding his ability to perform own ADLs. Where is your father living now? With you?
