Neurological soft signs and psychopathology. I. Findings in schizophrenia

Systematic, standardized evaluations for neurological soft signs were conducted on five psychiatric populations and a control group of medical inpatients. Soft signs were grouped according to their probable clinical association with cortical lobe dysfunction. Preliminary results indicated that schizophrenics, compared to other groups, showed significant increased presence of soft signs presumably related to frontal and parietal lobe dysfunction.
