DEPRESSION | Warning signs

The elderly are the highest-risk population in the United States for suicide. But few suicide-prevention programs target them — a result, advocates say, of scarce funding and lack of concern for older Americans. A look at some signs of depression, a top risk factor for suicide.

Persistent sad, anxious or “empty” mood.

Feelings of hopelessness, pessimism, guilt.

Loss of interest in hobbies and other activities that were once enjoyed.

Fatigue, restlessness, irritability.

Difficulty concentrating, remembering, making decisions.

Insomnia or oversleeping.

Significant weight change.

Persistent physical symptoms that do not respond to treatment, such as headaches, digestive disorders and chronic pain.

Thoughts of death.

Other factors that put elderly people at risk for suicide include:

Previous suicide attempts or family history of suicide.

Existing or past mental disorders.

History of alcohol and substance abuse.

Loss of personal, social or professional ties.

Illness, isolation, access to lethal weapons.
