[Diagnostic criteria in multiple sclerosis]

Almost all the neurological diseases can imitate multiple sclerosis. No strictly specific laboratory test has become as yet available for its diagnosis. Information obtained by clinical examination of the patient--dissemination of different symptoms at the same time and the same symptom in various periods--supplemented by neuroradiological, neurophysiological and biological supplementary tests allow making diagnosis of multiple sclerosis with about hundred percent certainty.
