Schizophrenia is a mental disorder often characterized by abnormal social behaviour and failure to recognize what is real. Common symptoms include false beliefs,unclear or confused thinking,auditory hallucinations,reduced social engagement and emotional expression,and inactivity. Maps of the average annual rates of brain surface contraction in (a) individuals at ultra-high risk for developing psychosis who converted to psychosis (converters) versus those who did not convert (non converters),and (b) schizophrenia patients versus healthy controls. Converters and schizophrenia patients showed significantly greater brain-contraction rates compared with and healthy individuals,respectively. A similar pattern of prominent prefrontal surface contraction was shared across groups. For the top two rows,bluer areas indicate regions of higher surface motion,while red and pink areas indicate areas of negative motion,or contraction; in the bottom row,red |
