Adjusted volumetric changes from baseline to 12 months in adolescents with bipolar disorder (n=30), adolescents with attention deficit hyperactivity disorder (ADHD; n=29), and healthy (n=24) adolescents in A. left amygdala (mixed model group*time effect, p=0.005) and B. right amygdala (mixed model group*time effect, p=0.002).

* At 12 months, adolescents with bipolar disorder exhibit statistically significantly differences in A. left amygdala volume compared with adolescents with attention deficit hyperactivity disorder (ADHD; p=0.0002) and healthy adolescents (p=0.0002) and B. in right amygdala volume compared with adolescents with attention deficit hyperactivity disorder (ADHD; p=0.0002) and healthy adolescents (p=0.003)

** Volume change from baseline to 12 months is significant for: A. left amygdala in healthy adolescents (p=0.008) and adolescents with attention deficit hyperactivity disorder (ADHD; p=0.0009) and B. right amygdala in adolescents with attention deficit hyperactivity disorder (ADHD; p<0.0001).
