Depression and Alzheimer's Disease

Key points
- Depression is very common among people who have Alzheimer's disease.
- It may be difficult for you to know if your family member is depressed.
- The doctor will also ask you and other family members and caregivers whether the person has any new or changed behaviors.
- Antidepressant medicines can be very helpful for people who have Alzheimer's disease and depression.
Do people who have Alzheimer's disease become depressed?
Yes. Depression is very common among people who have Alzheimer's disease. In many cases, they become depressed when they realize that their memory and ability to function are getting worse.
Unfortunately, depression may make it even harder for a person who has Alzheimer's disease to function, to remember things and to enjoy life.
How can I tell if my family member who has Alzheimer's disease is depressed?
It may be difficult for you to know if your family member is depressed. You can look for some of the typical signs of depression, which include the following:
- Not wanting to move or do things (called apathy)
- Expressing feelings of worthlessness and sadness
- Refusing to eat and losing weight
- Sleeping too much or too little
Other signs of depression include crying and being unusually emotional, being angry or agitated, and being confused. Your family member who has Alzheimer's disease may refuse to help with his or her own personal care (for example, getting dressed or taking medicines). He or she may wander away from home more often.
Alzheimer's disease and depression have many symptoms that are alike. It can be hard to tell the difference between them. If you think that depression is a problem for your relative who has Alzheimer's disease, talk to his or her family doctor.
How can the doctor help?
The doctor will talk with your relative. The doctor will also ask you and other family members and caregivers whether the person has any new or changed behaviors. The doctor will check your relative and may wish to do some tests to rule out other medical problems. He or she may suggest medicines to help your family member feel better. The doctor may also have some advice for you and other family members and caregivers on how to cope. He or she may recommend support groups that can help you.
What medicines can help reduce depression?
Antidepressant medicines can be very helpful for people who have Alzheimer's disease and depression. These medicines can improve the symptoms of sadness and apathy, and they may also improve appetite and sleep problems. Don't worry-these medicines are not habit-forming. The doctor may also suggest other medicines that can help reduce upsetting problems, such as hallucinations or anxiety.
