Defining Depression & Treatment

Depression is no small problem. The disorder, which affects 6.7 percent of the U.S. population, makes it difficult to work and handle daily tasks. At its worst, it can lead to dangerous and suicidal behavior. Depression can also cause pain and distress for friends, family members and others.

Although the exact cause of depression isn’t known, researchers believe that the disorder is due to a chemical imbalance in the brain. Contributing factors may be heredity, traumatic emotional events, medical conditions, alcohol or drug abuse, sleeping problems, social isolation, neglect or the side effects of certain medications.

Symptoms

Individuals suffering from depression typically experience prolonged sadness, anger, a sense of loss and/or extreme pessimism. Common characteristics of depression include:

• Agitation, restlessness, and irritability.
• Dramatic change in appetite, often with weight gain or loss.
• Extreme difficulty concentrating.
• Fatigue and lack of energy.
• Feelings of hopelessness and helplessness.
• Feelings of worthlessness, self-hate, and inappropriate guilt.
• Inactivity and withdrawal from usual activities, a loss of interest or pleasure in activities that were once enjoyed (such as sex).
• Thoughts of death or suicide.
• Trouble sleeping or excessive sleeping.

  Left untreated, depression can worsen.
