Detection of Brain-Damage in Schizophrenics as Measured by the Whitaker Index of Schizophrenic Thinking and the Luria-Nebraska Neuropsychological Battery
Neuropsychological performance of schizophrenics with and without brain-damage was measured by the Whitaker Index of Schizophrenic Thinking and the Luria-Nebraska Neuropsychological Battery. Inpatient volunteers (11 brain-damaged and 15 non-brain-damaged) with a diagnosis of schizophrenia were administered both tests individually. Results indicated that 8 of the 14 summary scales of the Luria-Nebraska but none of the 5 scores on the Whitaker differentiated between groups. While cognitive variables as measured by the Whitaker may be further impaired with organicity, other variables measured by the Luria-Nebraska were more effective in differentiating between groups.
