Strain and negative events in life can lead to depression and affect the psychological stability of older people. Depression may occur in elderly people due to fears of disability and death. Studies show that depression can be attributed to a function of disability, social isolation or poverty, all of which tend to increase with age. When these problems are controlled, and fears are overcome, depression can be prevented. Depression can appear in many ways. Symptoms may include sleep disturbance, such as sleeping too much or too little, poor appetite, feelings of worthlessness or guilt, and loss of interest in usual activities. Treatment for depression can consist of counseling, sometimes aided by the use of anti-depressants. Anti-depressants assist in relieving some of the tension, enabling the patient to be more open in discussing personal problems. The best treatment involves the combined use of medical, educational, and psychological assistance. For more information on depression in seniors, consult a health care provider.
