Depression is a condition in which a person feels discouraged, sad, hopeless, unmotivated, or disinterested in life in general. When these feelings last for a short period of time, it may be a case of "the blues." But when such feelings last for more than two weeks and when the feelings interfere with daily activities such as taking care of family, spending time with friends, or going to work or school, it may be a major depressive episode.
Major depression is a treatable illness that affects the way a person thinks, feels, behaves, and functions. At any point in time, 3 to 5 percent of people suffer from major depression; the lifetime risk is about 17 percent. Campus data shows that almost 18% of students have experienced a negative impact on their academics due to symptoms of depression.
Types of Depression
Three main types of depressive disorders—major depression, persistent depressive disorder, and bipolar disorder—can occur with any of the anxiety disorders.
Major depression involves at least five of these symptoms for a two-week period. Such an episode is disabling and will interfere with the ability to work, study, eat, and sleep. Major depressive episodes may occur once or twice in a lifetime, or they may recur frequently. They may also take place spontaneously, during or after the death of a loved one, a romantic breakup, a medical illness, or other life event. Some people with major depression may feel that life is not worth living and some will attempt to end their lives.
Persistent depressive disorder, or PDD, (formerly called dysthymia) is a form of depression that usually continues for at least two years. Although it is less severe than major depression, it involves the same symptoms as major depression, mainly low energy, poor appetite or overeating, and insomnia or oversleeping. It can manifest as stress, irritability, and mild anhedonia, which is the inability to derive pleasure from most activities. People with PDD might be thought of as always seeing the glass as half empty.
Bipolar disorder, once called manic-depression, is characterized by a mood cycle that shifts from severe highs (mania) or mild highs (hypomania) to severe lows (depression). During the manic phase, a person may experience abnormal or excessive elation, irritability, a decreased need for sleep, grandiose notions, increased talking, racing thoughts, increased sexual desire, markedly increased energy, poor judgment, and inappropriate social behavior. During the depressive phase, a person experiences the same symptoms as would a sufferer of major depression. Mood swings from manic to depressive are often gradual, although occasionally they can occur abruptly.
Depression and Anxiety Disorders: Not the Same
Depression and anxiety disorders are different, but people with depression often experience symptoms similar to those of an anxiety disorder, such as nervousness, irritability, and problems sleeping and concentrating. But each disorder has its own causes and its own emotional and behavioral symptoms. Many people who develop depression have a history of an anxiety disorder earlier in life. There is no evidence one disorder causes the other, but there is clear evidence that many people suffer from both disorders.
