Youth with cyclothymic disorder show few differences from youth with medically unspecified bipolar disorder, according to a study published in the Journal of Affective Disorders. However, persistent subsyndromal mood symptoms could have implications for the severity and course of a disorder.
This study included 154 young participants, 29 of whom met criteria for a research diagnosis of cyclothymic disorder. Youth with this disorder showed a higher likelihood for disruptive behavior disorder (P =.014), irritability (P =.039), sensitivity to rejection, and mood reactivity. Youth with unspecified bipolar disorder were likelier to experience mood episodes during the follow-up period and were at higher risk of developing depression (P =.024) or hypomania (P =.016).
