Leon has recently been diagnosed with schizophrenia. He experiences frequent auditory hallucinations and believes his every movement is being monitored by a satellite. His identical twin brother, Marcus, was diagnosed with schizophrenia three years ago. A recent neuroimaging scan of Leon’s brain showed significantly enlarged ventricles and reduced activity in his ventral striatum compared to neurotypical individuals. His psychiatrist has prescribed him a classical (typical) antipsychotic medication, which has led to a significant reduction in the severity of his hallucinations.
