December 9, 2003
  • Persistent sad or empty feelings
  • Feelings of hopelessness or pessimism
  • Loss of interest or pleasure in activities that were previously enjoyable, including sex
  • Fatigue or decreased energy 
  • Difficulty concentrating, making decisions or remembering
  • Trouble sleeping, including early morning awakening or sleeping too much
  • Appetite or weight changes 
  • Restlessness or irritability 
  • Persistent physical problems that don't respond to medical treatment
    thoughts of death or suicide

All of these symptoms need not be present for a diagnosis of depression. Some individuals experience only a few, others many. The symptoms also may change in intensity over time.
