Bipolar disorder (manic-depressive illness)
SUMMARY: Bipolar disorder (manic-depressive illness) is a neurobiological brain disorder that affects approximately 2.3 million Americans today, or almost 1 percent of the population. Individuals diagnosed with this disease have mood swings that alternate from periods of severe highs (mania) to extreme lows (depression). Suicide is the number one cause of premature death among people with bipolar disorder, with 15 percent to 17 percent taking their own lives as a result of negative symptoms that come from untreated illness.Individuals diagnosed with manic-depressive illness, or bipolar disorder, have mood swings that alternate from periods of severe highs (mania) to extreme lows (depression). These mood swings, which are out of proportion or totally unrelated to events in a person’s life, affect thoughts, feelings, physical health, behavior, and functioning.
Bipolar disorder is a neurobiological brain disorder that affects approximately 2.3 million Americans today, or almost 1 percent of the population.
Although bipolar disorder usually begins in adolescence or early adulthood, it can sometimes start in early childhood or as late as age 40 or 50.
Generally, people with bipolar disorder consult three to four doctors and spend more than eight years seeking treatment before they receive a correct diagnosis.
The average person has four episodes of mania or depression during the first 10 years of the illness. Men are more likely to start with a manic episode, and women are more likely to begin with a depressive episode.
Symptoms of bipolar disorder
Although no single pattern of symptoms fits every individual with bipolar disorder, there are four distinct types of mood episodes that can occur over the course of the illness
Mania often begin with a pleasurable sense of heightened energy, creativity, and social ease – feelings that without proper medical treatment can quickly escalate out of control into a full-blown manic episode. People experiencing mania typically lack self-awareness, deny anything is wrong, and angrily blame anyone who points out a problem. In addition to feeling unusually “high,” euphoric or irritable, the person also may exhibit symptoms such as:
Hypomania is a milder form of mania with similar yet less severe symptoms and less overall impairment. In hypomania, for example, the individual may have an elevated mood, feel better than usual, and be more productive. These episodes often feel good, and the quest for hypomania may even cause people to stop taking their medication.
Depression takes away the capacity to experience pleasure, often causing profound sadness and irritability, changes in sleep patterns, a decrease in appetite, an inability to concentrate, low self-esteem, and thoughts of suicide. Severe depressions also may include hallucinations or delusions.
Mixed episode is perhaps the most disabling since an individual can experience both mania and depression simultaneously or at different times throughout the day.
Treating bipolar disorder
Although there is no cure for bipolar disorder, it is a highly treatable disease. According to the National Advisory Mental Health Council, the treatment success rate for bipolar disorder is a remarkable 80 percent.
It is important to diagnose and treat bipolar disorder as early as possible to help people avoid or reduce relapses and rehospitalizations. Several promising, large-scale studies suggest early intervention may forestall the worst long-term outcomes of this devastating brain disorder.
Individuals experiencing mania often lack self-awareness and do not recognize that they are ill, a clinical symptom called anosognosia. They may require treatment in the hospital to prevent self-destructive, impulsive, or aggressive behavior. Hospital stays can be as brief as two weeks and as long as six months.
The most important types of medication used to control the symptoms of bipolar disorder are mood stabilizers and antidepressants.
