My husband of 50 years diagnosed with vascular dementia 2 years ago. This past year he no longer drives, doesn't want to leave the house, won't shower, shave or get his haircut. Sometimes refuses to go to doctor appts. He won't let anyone help him with difficult tasks. When children come to visit, he visits a while and then retreats to his room. Hasn't participated in family activities for quite awhile. Suggestions on how to get him to attend to personal hygiene issues. I know it is hard for him, but he emphatically refuses help.
