According to the Mayo Clinic, there are several types of bipolar disorder, each with their own unique symptoms. The exact symptoms vary from person to person and include rapid speech, aggressive behavior, agitation, poor performance in school or work and a sense of euphoria for the manic episodes and hopelessness, depression, fatigue, trouble sleeping, loss of interest in activities once enjoyed by the patient and guilt in the depressive episodes.
Other signs of bipolar disorder, according to the Mayo Clinic, include seasonal changes in mood and rapid changes in mood. Symptoms can also include bouts of psychosis, which are bouts that result in a detachment from reality. These bouts can include the strong belief in false things or seeing things that are not really there. The most common symptoms in children and adolescents are aggression, an explosive temper, reckless behavior and rapid changes in mood, such as being happy one moment and then crying excessively in the next.
The Mayo Clinic suggests that one sees his doctor if he has symptoms of depression, as bipolar disorder does not get better on its own. Also, it is extremely important that one seeks immediate medical help if one begins feeling hopeless or has thoughts of committing suicide.
