[Paroxysmal attacks of dysarthria and ataxia in multiple sclerosis]

A description of 2 cases of disseminated sclerosis during exacerbations and paroxysms of dysarthria and ataxia in the clinical picture is given. These attacks are connected with processes of demyelinization and are differentiated with epilepsy. On the basis of neurophysiological studies the mechanisms of paroxysmal dysarthria and ataxia are discussed. The attacks were arrested under the influence of carbamazepine. The action of the drug is explained by its manifold properties.
