Assessments of higher cortical functioning are often neglected in
patients with possible coarse neurobehavioral psychiatric disease, such as
dementia, stroke, or focal cerebral lesions. When performed, the short
Folstein Mini-Mental State Exam (MMSE) is typically used. The authors'
research on 45 neuropsychiatric patients compared the MMSE with a new
20-30-minute bedside examination, the Screening Cerebral Assessment of
Neppe (BROCAS SCAN). This screens 10 areas: recall, recognition,
orientation, organization of thought, concentration, calculation, agnosia,
apraxia, speech, and sensory-motor-reflex phenomena. The BROCAS SCAN
(total) correlated extremely well with neuropsychiatric prediction, MRI
changes, and neuropsychological testing, and distinguished diagnoses,
demonstrating construct and face validity. It also accounted for a larger
proportion of variance than the MMSE in correlating with these parameters
and was more sensitive in mildly cognitive impaired patients. The briefer
first section of the BROCAS SCAN, the core SCAN, also showed statistically
relevant relationships to age, diagnosis, MRI, and neuropsychiatric
prediction.Abstract Teaser
