People experiencing the lows of bipolar disorder and depression may have unexplained crying spells, become easily angry or worried, have an inability to concentrate and be unable to take pleasure in former interests, explains the Depression and Bipolar Support Alliance. In extreme cases, recurring thoughts of death or suicide may occur. Individuals with symptoms of bipolar or depression should consult with a medical professional for assistance.
Individuals with bipolar disorder experience a different set of symptoms during the mania stage, according to Depression and Bipolar Support Alliance. These symptoms include increased energy and mental activity, excessive irritability or aggressive behavior, racing thoughts and speech, and reckless behavior. Some individuals may also have exaggerated optimism or self-confidence, act impulsively or experience grandiose delusions. In addition, increased energy may cause a decreased need for sleep and a flight of ideas that are difficult to manage. In severe cases, patients may also experience hallucinations and delusions.
