Bipolar disorder is a mental condition characterized by extreme mood swings between mania and depression. During manic episodes, people with bipolar disorder experience elevated mood, decreased need for sleep, impulsivity, and increased activity or energy. Depressive episodes involve feelings of guilt, anxiety, and sadness that can last for days or weeks. There are four main types of bipolar disorder that are differentiated based on the severity and frequency of manic episodes. Genetics, biological traits like neurotransmitter imbalances, and environmental stressors can all potentially contribute to the development of bipolar disorder. Self-help strategies include establishing routines, getting enough sleep, avoiding drugs, and seeking help to manage symptoms.
