Pediatric bipolar disorder is commonly characterized by outbursts of anger, irritability and psychosis, rather than euphoric mania, which is more likely to be seen in adults. Early onset bipolar disorder is more likely to manifest as depression rather than mania or hypomania.
Some have frequent mood disruptions, while others experience only a few over a lifetime. There are four types of mood episodes in bipolar disorder: mania, hypomania, depression, and mixed episodes. Each type of bipolar disorder mood episode has a unique set of symptoms. In the manic phase of bipolar disorder, feelings of heightened energy, creativity, and euphoria are common.
