Longitudinal assessment of the course of major psychiatric disorders has been advanced by studies from onset, but only rarely have large numbers of patients with a range of psychotic and major affective disorders been studied simultaneously and systematically from illness-onset. The decade-long McLean-Harvard First Episode Project & International Consortium for Bipolar Disorder Research has systematically followed-up large numbers of patients with DSM-IV bipolar or psychotic disorders from first hospitalization. Major findings among patients with bipolar I disorder include: [a] full functional recovery from initial episodes was uncommon, and full symptomatic recovery, much slower than early syndromal recovery; [b] risks of relapse, recurrence, and switching were very high in the first two years; [c] most early morbidity was depressive-dysphoric, as reported in mid-course; [d] initial depression or mixed-states predicted more later depressive and overall morbidity, whereas initial mania or psychosis predicted later mania and a better prognosis; [e] based on within-subject modeling, most patients did not show progressive cycling over time, and illness-course was rather chaotic within and among patients; [f] treatment-latency or episode-counts were unassociated with responsiveness to long-term mood-stabilizing treatment; [g] very high rates of suicidal behavior and accidents occurred early; [h] early substance-use comorbidity associated with anxiety; [i] factor-analysis of prodromal symptoms predicted bipolar disorder much better than non-affective psychotic disorders. Project findings indicate that the course of bipolar I disorder is much less favorable than had been believed formerly, despite clinical treatment with modern mood-stabilizing and other treatments.
