What are the Different Forms of Depression?
There are several forms of depressive disorders that occur in both women and men. The most common are major depressive disorder and dysthymic disorder. Minor depression is also common.
Minor depression may also occur. Symptoms of minor depression are similar to major depression and dysthymia, but they are less severe and/or are usually shorter term.
Some forms of depressive disorder have slightly different characteristics than those described above, or they may develop under unique circumstances. However, not all scientists agree on how to characterize and define these forms of depression. They include the following:
What is a “Mixed” State?
A mixed state is when symptoms of mania and depression occur at the same time. During a mixed state depressed mood accompanies manic activation.
What is Rapid Cycling?
Sometimes individuals may experience an increased frequency of episodes. When four or more episodes of illness occur within a 12-month period, the individual is said to have bipolar disorder with rapid cycling. Rapid cycling is more common in women.
What are the Causes of Bipolar Disorder?
While the exact cause of bipolar disorder is not known, most scientists believe that bipolar disorder is likely caused by multiple factors that interact with each other to produce a chemical imbalance affecting certain parts of the brain. Bipolar disorder often runs in families, and studies suggest a genetic component to the illness. A stressful environment or negative life events may interact with an underlying genetic or biological vulnerability to produce the disorder. There are other possible “triggers” of bipolar episodes: the treatment of depression with an antidepressant medication may trigger a switch into mania, sleep deprivation may trigger mania, or hypothyroidism may produce depression or mood instability. It is important to note that bipolar episodes can and often do occur without any obvious trigger.
How is Bipolar Disorder Treated?
While there is no cure for bipolar disorder, it is a treatable and manageable illness. After an accurate diagnosis, most people can achieve an optimal level of wellness. Medication is an essential element of successful treatment for people with bipolar disorder. In addition, psychosocial therapies including cognitive-behavioral therapy, interpersonal therapy, family therapy, and psychoeducation are important to help people understand the illness and to internalize skills to cope with the stresses that can trigger episodes. Changes in medications or doses may be necessary, as well as changes in treatment plans during different stages of the illness.
