Hello, I'd like to help you with your question.
It sounds like your father might be experiencing the beginnings of Dementia
. One of the most common symptoms of Dementia is the inability to control moods and an increase in aggression.
There are different kinds of dementia. One kind, called frontotemporal dementia, is marked by changes in personality and/or unusual behavior that is not the typical behavior of the person affected. They may also be rude to others and not show concern they are hurting the other person.
The first step to take is to have your father see his doctor. Dementia needs to be ruled out first before other possible mental health disorders are considered. The doctor can do a thorough check up and let you know if your father might have Dementia. If not, the doctor can refer your father for mental health services. There are very few mental health disorders that start late in life, however, so Dementia should be considered first.
You may also want to consider starting aging services in your father's home. There may be a Department of Aging in your area that you can contact either through the United Way or through your city or county's local government. They will often provide respite for your family, caregivers, meals on wheels and other services. Your father's doctor may also be able to order services for him, Check when your father goes for his appointment.
It can also help your family to get involved with aging support. Therapy and self help groups can help your family feel less stressed and find out about other resources that may help you cope with your fathers situation. Here are some resources to get you started:
