Major depression of late lifeEdit
Major Depression is a mental disorder characterized by an all-encompassing low mood accompanied by low self-esteem, and loss of interest or pleasure in normally enjoyable activities.Nearly 5 million of the 31 million Americans who are 65 years or older are clinically depressed, and 1 million have major depression. Approximately 3 percent of healthy elderly persons living in the community have major depression. Recurrence may be as high as 40 percent. Suicide rates are nearly twice as high in depressed patients as in the general population. Major depression is more common in medically ill patients who are older than 70 years and hospitalized or institutionalized. Severe or chronic diseases associated with high rates of depression include stroke (30 to 60 percent), coronary heart disease (8 to 44 percent), cancer (1 to 40 percent), Parkinson’s disease (40 percent), Alzheimer’s disease (20 to 40 percent), and dementia (17 to 31 percent).
Minor depression of late lifeEdit
Minor depression is a clinically significant depressive disorder that does not fulfill the duration criterion or the number of symptoms necessary for the diagnosis of major depression. Minor depression, which is more common than major depression in elderly patients, may follow a major depressive episode. It also can be a reaction to routine stressors in older populations. Fifteen to 50 percent of patients with minor depression develop major depression within two years.
