Applicability of the abbreviated neuropsychologic battery (NEUROPSI) in Alzheimer disease patients.

NEUROPSI is a brief neuropsychologic battery developed to briefly assess a wide spectrum of cognitive functions. The aim of this study was to examine the applicability of a Portuguese version of this battery and verify the efficacy in detecting cognitive impairment in Alzheimer disease (AD) patients. NEUROPSI was applied to 75 elderly people, 25 patients with probable AD in mild stage (AD1), 25 patients in moderate stage (AD2), and 25 healthy elderly persons (control group), matched with the AD patients for age and schooling. Before testing all participants were applied the Mini-Mental State Examination. Results showed significant differences in total scores of the tests; NEUROPSI (P<0.001) and Mini-Mental State Examination (P<0.001), and the control group scored highest in both of the tests followed by groups AD1 and AD2. Differences were also found between the initial phase and the moderate phase. Results indicate that NEUROPSI is an efficient instrument for detecting AD patients in the initial stage of the disease.
