The authors compared Alz-50 immunoreactivity in the brain tissue of nine
cognitively impaired elderly schizophrenic patients and 13 elderly
comparison subjects, both without neuritic plaques or neurofibrillary
tangles, and 13 patients with Alzheimer's disease. Alz-50 reactivity was
absent in the schizophrenic patients, indicating that geriatric,
cognitively impaired patients are unlikely to display the pathology of
Alzheimer's disease.Abstract Teaser
