Brain networks differ among those with severe schizophrenia, CAMH study shows

A new study by CAMH reveals that people with severe schizophrenia have distinct differences in their brain networks compared to those with schizophrenia, bipolar disorder, and healthy individuals. The research provides strong evidence that schizophrenia is not one but rather multiple brain disorders.
