Abstract:
The performance of patients with amyotrophic lateral sclerosis (ALS) on selective neuropsychological tests was examined in regard to the applicability of such examinations to diagnosis. Eighteen patients with ALS, and 15 age- and education-matched controls were given a battery of tests designed to assess motor and intellectual functions. The ALS group displayed significantly lower scores on all tests than those in the control group. Correlation analyses on the several motor and neuropsychological results in ALS group revealed that there was a significant negative correlation between upper motor symptoms and mini-mental state examination, as well as memory tests.
