Electrophysiological (BAEPs) changes in subacute sclerosing panencephalitis.
Over a period of time, the authors have studied a case of subacute sclerosing panencephalitis (SSPE), by means of brainstem auditory evoked potentials (BAEPs). The observed abnormalities of the conduction time along the early auditory pathways appeared to be related to the clinical picture; in fact, during periods of transitory clinical improvement these abnormalities were less evident. In addition, the encountered electrophysiological alterations consisted of a marked pathologic increase in the III-V interpeak latencies. The authors suggest that the BAEPs findings in their case could have been influenced by either unfavourable endogenous conditions (edema, electrolyte changes, etc.) or CNS segmental lesions due to focal viral distribution.
