Abstract
Schizophrenia is severe mental disorder. A genetic study is thought to be effective to reveal pathophysiology of schizophrenia since genetic factors are involved in developing the disease. Molecular biology has been performed to detect etiology of the mental illness. However, genetic studies have not found a causative mutation from patients with schizophrenia because the psychotic illness is large heterogeneous syndrome, not homogeueous disease. Mind is depending upon central nervous systems but is not equal to the brain. We need to study on not only the brain but also the mind.
