OBJECTIVES Bipolar disorder and schizophrenia share common pathophysiological processes and may have similar perceptual abnormalities. Mismatch negativity (MMN) and P3a - event-related potentials associated with auditory preattentional processing - have been extensively studied in schizophrenia, but rarely in bipolar disorder. Furthermore, MMN and P3a have not been examined between diagnostic s...

The sample consisted of 837 outpatients from mental health and substance abuse centres. We used the Mini Internatio...
