Major depression

Alternate Names : Depression - major, Unipolar depression, Major depressive disorder

Symptoms & Signs

Depression can change or distort the way adolescents see themselves and their lives, as well as other people around them. People who have depression usually see everything with a more negative attitude, unable to imagine that any problem or situation can be solved in a positive way.

Symptoms 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

Depression can appear as anger and discouragement, rather than as feelings of hopelessness and helplessness. Use of alcohol or illegal substances may be more likely to occur.

If depression is very severe, there may also be psychotic symptoms, such as hallucinations and delusions. These symptoms may focus on themes of guilt, inadequacy, or disease.

Diagnosis & Tests

Major depression is diagnosed if a person reports having five or more depressive symptoms for at least 2 weeks. Beck's Depression Scale Inventory or other screening tests for depression can be helpful in making the diagnosis.

Before diagnosing depression, the health care provider should rule out medical conditions that can cause symptoms of depression.
