Bipolar disorder affects 3% of the general population, with significant functional limitations and high rates of psychiatric hospitalization in children and adolescents. The diagnostic criteria for bipolar I disorder in adolescents include mania, euphoria, and irritability, while mixed episodes are common in this age group.
People with bipolar disorder experience excessive positive emotions, even in neutral situations, which can lead to reckless behavior and relationship problems. This persistent positivity may serve as an early warning sign for relapse.
