The aim of this study is to review the recent literature on the prevalence, correlates, consequences, and treatment patterns of bipolar II disorder. Recent findings In the past 2 years, several important studies have been conducted in the bipolar II field. The World Mental Health Survey initiative provides us with prevalence rate across 11 countries, while several meta-analyses on…

Findings demonstrate heterogeneity in major depressive disorder and support the validity of inclusion of subthreshold mania in the diagnostic classification and the broadening of criteria for bipolar disorder.

Examination of rates and predictors of progression to bipolar I and II diagnoses in a nonpatient sample of college-age participants with high General Behavior Inventory scores and childhood or adolescent onset of "soft" bipolar spectrum disorders followed longitudinally for 4.5 years confirms high BAS sensitivity and the interaction of high BAS and high Behavioral Inhibition System (BIS) sensitivities predicted greater likelihood of progressionto bipolar I.

This study showed, for the first time, that experiencing (hypo)manic symptoms is a common adolescent phenomenon that infrequently predicts mental health care use and suggests that the onset of bipolar disorder can be elucidated by studying the pathway from non-pathological behavioural expression to dysfunction and need for care.
