Outline of Final Research Achievements |
Duration and frequency mismatch negativity were recorded for subjects (first episode schizophrenia patients, ultra high risk patients and healthy controls). Cross sectional study showed that duration MMN is impaired in patients groups. Longitudinal study showed that these MMN do not change for 1 to 2 years. Duration mismatch negativity can be a biological marker for early stage schizophrenia.
