Reaction time deficit in multiple sclerosis.
50 multiple sclerosis (MS) patients were evaluated, according to an objective weighting scale measuring neurologic deficit, and investigated with continuous reaction time (CRT). Compared to a group of 105 controls, the reaction times of the MS patients were significantly delayed. The CRT method could correctly classify 80% of the controls and 72% of the patients. The CRT was especially sensitive for patients in the progressive phase of the disease and independent of dyscoordination.
