FAMILIAL PAROXYSMAL ATAXIA

The paper provides clinical and paraclinical findings on 3 patients fr om one family (two brothers and father) suffering from familial paroxy smal ataxia. The authors observed psychosensory disturbances not typic al, according to the literature for attacks of ataxia, disarthria and nystagmus. The evidence obtained on cerebral and spinal evoked potenti als made it possible to diagnose multilevel impairment of nervous impu lse conduction in the somatosensory system which may be due to metabol ic disturbances underlying the disease.
