Throughout the progression of dementia, mood changes may occur and sometimes can be a complete surprise. Your family member may experience difficult mental, emotional and even physical challenges that cause these increasing mood changes. When a person can’t remember or is constantly confused they may be frustrated, fearful and even fighting the changes. It’s no wonder that mood swings are a common problem among those who have dementia. It is wise to accept and anticipate that dementia is the cause of the mood changes. Avoid thinking that one is having personality changes. Separate your loved one, the person you know and care about, from the disease and its symptoms.
