Changes that many older individuals face - such as loss through the death of a spouse or multiple medical issues related to aging - can lead to depression. Those elderly individuals without a strong social support system are at high risk for depression. Depression doesn't have to be a part of aging. Most seniors actually are satisfied with their lives despite the challenges of growing older.

If depression in the elderly remains untreated it does not only prevent older adults from enjoying life in general, it also takes a potential toll on their general health. If the right treatment for depression is secured the elderly have a good chance of living vibrant and fulfilling lives. Treatment of depression in the elderly will also have a positive influence on the whole family system surrounding the elder person.
 
Many elderly adults face significant life changes and stresses that put them at risk for depression. Those at the highest risk include older adults with a personal or family history of depression, failing health, substance abuse problems, or inadequate social support.

Some of the causes and risk factors that contribute to depression in the elderly are:

• Loneliness and isolation – Living alone; a dwindling social circle due to deaths or relocation; decreased mobility due to illness or loss of driving privileges.

• Reduced sense of purpose - Feelings of purposelessness or loss of identity due to retirement or physical limitations on activities.

• Health problems – Illness and disability; chronic or severe pain; cognitive decline; damage to body image due to surgery or disease.

• Medications – Many prescription medications can trigger or exacerbate depression.

• Fears – Fear of death or dying; anxiety over financial problems or health issues.

• Recent bereavement - The death of friends, family members, and pets; the loss of a spouse or partner.
