Bipolar Disorder: Symptoms & Signs

The symptoms of bipolar disorder depend upon whether the sufferer is experiencing a depressive or manic episode. A person must have experienced at least one manic episode to be diagnosed with bipolar disorder. Symptoms and signs of manic episodes include

  • elevated or expansive mood,
  • rushed or pressured speech,
  • racing thoughts,
  • decreased need for sleep,
  • poor judgment,
  • increased goal-directed activity,
  • impulsivity,
  • grandiose thoughts (thinking one has superpowers or special abilities), and

Major depressive episodes often alternate with manic episodes in bipolar disorder. These episodes can be characterized by

  • feelings of hopelessness,
  • depressed mood,
  • decreased interest in pleasurable activities,
  • changes in appetite,
