Brain Imaging of Cognition Inn Schizophrenia and Depression
Schizophrenia / Schizoaffective Disorder | Depression / Major Depressive DisorderSchizophrenia and depression are among the most disabling disorders in all of medicine. Cognitive deficits play a key role in patients' disability, affecting their capacity to contribute actively to society by sustaining employment or academic activity. Moreover, cognitive difficulties tend to persist even after the stabilization of other clinical symptoms. Verbal memory and emotion regulation are two important cognitive domains that are impaired in schizophrenia and depression and are associated with patients' functional outcomes. In this study, we are using brain imaging to investigate the brain mechanisms underlying these cognitive deficits in these populations.
