It is difficult to firmly establish the prognosis of first episode BD patients with respect to progression to other psychiatric illness or relapse to another psychotic episode. This is due to the fact that high quality follow-up studies of large cohorts of BD patients are unavailable in part because of the uncommon nature of the illness and non-standardization of diagnostic methods. Investigators attempting to define the prognosis in BD have used data from similar conditions, i.e. acute transient psychotic disorder (ATPD) and brief psychotic disorder (BPD). A meta-analysis involving 11,000 patients estimated the rate of recurrent psychotic episodes in ATPD and BPD patients was 51% at 30 months compared to first episode schizophrenia patients who had an 84% recurrence rate at 36 months. As suggested by the various definitions of BD discussed above, rapid recovery and return to pre-morbid level of function is expected, though quantitative data is lacking.
