Parkinson’s disease is a chronic disorder that is going to greatly affect your father for the rest of his life. When someone finds out they have a chronic condition like this, their shock can quickly turn into denial of the disease.
You can help your loved one overcome Parkinson’s disease denial by being supportive. Help them learn everything they can about their condition. Help make sure they are taking medications and following their treatment plan. Try and schedule some time for your father’s physician to sit with them and go over all of their concerns.
