Bipolar Disorder
By Dr Ananya Mandal, MD
Bipolar disorder is a mental health disorder that was previously called manic depressive psychosis or manic depression. The condition is typically characterized by a mood that "swings" from a depressive state where an individual may feel down and lethargic to a manic phase that may cause them to feel hyperactive and jittery.
In a healthy individual, mood swings are usually transient, lasting for a few hours or a day. However, in the case of bipolar disorder, moods may last for weeks or months at a time with a normal mood being the exception.
