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.
A person with bipolar disorder may have distinct manic or depressed states. A person with mixed episodes experiences both extremes simultaneously or in rapid sequence. Severe bipolar episodes of mania or depression may also include psychotic symptoms such as hallucinations or delusions. Usually, these psychotic symptoms mirror a personâs extreme mood.
