Question: What is (are) Depression ?
Answer: Everyone feels blue or sad now and then, but these feelings don't usually last long and pass within a couple of days. When a person has depression, it interferes with daily life and normal functioning, and causes pain for both the person with depression and those who care about him or her. Doctors call this condition "depressive disorder," or "clinical depression." Depression in Older Adults Important life changes that happen as we get older may cause feelings of uneasiness, stress, and sadness. For instance, the death of a loved one, moving from work into retirement, or dealing with a serious illness can leave people feeling sad or anxious. After a period of adjustment, many older adults can regain their emotional balance, but others do not and may develop depression. Depression is a common problem among older adults, but it is NOT a normal part of aging. In fact, studies show that most older adults feel satisfied with their lives, despite having more physical ailments. However, when older adults do suffer from depression, it may be overlooked because they may be less willing to talk about feelings of sadness or grief, or they may show different, less obvious symptoms, and doctors may be less likely to suspect or spot it. Sometimes it can be difficult to distinguish grief from major depression. Grief after loss of a loved one is a normal reaction to the loss and generally does not require professional mental health treatment. However, grief that lasts for a very long time following a loss may require treatment. Test Depression and Suicide Though it is widely believed that suicide more often affects young people, suicide is a serious problem among older adults, too  particularly among older men  and depression is usually a major contributing factor. Adults 65 and older have a suicide rate that is higher than the rate for the national population, but there are some major differences between older men and women. While suicide rates for older women are somewhat lower than those for young and middle-aged women, rates among men 75 and older are higher than those for younger men. In fact, white men age 85 and older have the highest suicide rate in the United States. Types of Depression There are several types of depression. The most common types are major depressive disorder and dysthymic disorder. - Major depressive disorder, also called major depression or clinical depression, is characterized by a combination of symptoms that interfere with a person's ability to work, sleep, concentrate, eat, and enjoy activities he or she once liked. Major depression prevents a person from functioning normally. An episode of major depression may occur only once in a person's lifetime, but more often, it recurs throughout a person's life.   - Dysthymic disorder, also called dysthymia, is a less severe but more long-lasting form of depression. Dysthymia is characterized by symptoms lasting two years or longer that keep a person from functioning normally or feeling well. People with dysthymia may also experience one or more episodes of major depression during their lifetime.

Other types of depression include subsyndromal depression, psychotic depression. and bipolar depression. - Subsyndromal depression  is common among older adults. It includes less severe but clear symptoms of depression that fall short of being major depression or dysthymia. Having subsyndromal depression may increase a person's risk of developing major depression.  - Psychotic depression occurs when a person has severe depression plus some form of psychosis, such as having disturbing false beliefs or a break with reality (delusions), or hearing or seeing upsetting things that others cannot hear or see (hallucinations).  - Bipolar depression, also called manic-depressive illness, is not as common as major depression or dysthymia. Bipolar disorder is characterized by cycling mood changesfrom extreme highs (e.g., mania) to extreme lows (e.g., depression).  Subsyndromal depression  is common among older adults.
