Mood Disorders

How much of the population is affected by mood disorders?
Each year, almost 44 million Americans experience a mental disorder. In fact, mental illnesses are among the most common conditions affecting health today.
What causes mood disorders / mental illness? Researchers believe most serious mental illnesses are caused by complex imbalances in the brain's chemical activity. They also believe environmental factors can play a part in triggering, or cushioning against, the onset of mental illness.

Are mood disorders treatable?
Like other diseases, mental illnesses can be treated. The good news is that most people who have mental illnesses, even serious ones, can lead productive lives with proper treatment. Mood disorders are one form of serious mental illness.

What are some common mood disorders?
Two of the most common mood disorders are depression and bipolar disorder, also known as manic-depressive illness.

Bipolar Disorder

Description: Extreme mood swings punctuated by periods of generally even-keeled behavior characterize this disorder. Bipolar disorder tends to run in families. This disorder typically begins in the mid-twenties and continues throughout life. Without treatment, people who have bipolar disorder often go through devastating life events such as marital breakups, job loss, substance abuse, and suicide.

Symptoms: Mania-expansive or irritable mood, inflated self-esteem, decreased need for sleep; increased energy; racing thoughts; feelings of invulnerability; poor judgment; heightened sex drive; and denial that anything is wrong. Depression-feelings of hopelessness, guilt, worthlessness, or melancholy; fatigue; loss of appetite for food or sex; sleep disturbances, thoughts of death or suicide; and suicide attempts. Mania and depression may vary in both duration and degree of intensity.

Depression

Description: When a person's feelings of sadness persist beyond a few weeks, he or she may have depression. According to the National Institute for Mental Health, three to four million men are affected by depression; it affects twice as many women. Researchers do not know the exact mechanisms that trigger depression. Two neurotransmitters-natural substances that allow brain cells to communicate with one another-are implicated in depression: serotonin and norepinephrine.
Symptoms: Changes in appetite and sleeping patterns; feelings of worthlessness, hopelessness, and inappropriate guilt; loss of interest or pleasure in formerly important activities; fatigue; inability to concentrate; overwhelming sadness; disturbed thinking; physical symptoms such as headaches or stomachaches; and suicidal thoughts or behaviors.
