The brain differences found in people with schizophrenia are mainly the result of the disease itself or its treatment, as opposed to being caused by genetic factors, according to a Dutch study.
Schizophrenia is a mental disorder that significantly affects cognition and usually contributes to chronic problems with behavior and emotion. Along with a breakdown of thought processes, the disorder is also characterized by poor emotional responsiveness, paranoia, auditory hallucinations and delusions.
People with schizophrenia are likely to have additional conditions, including major depression and anxiety.
The strong familial link of schizophrenia is thought to be as high as 81 percent, and researchers have suggested that schizophrenia-related brain abnormalities may be present in unaffected relatives, a notion that has been supported by several studies.
