[Epileptic attacks in subacute sclerosing panencephalitis (SSPE)].

The analysis is reported of the frequency of epileptic seizures in 125 cases of subacute sclerosing panencephalitis (SSPE). Sporadic, periodic and recurrent seizures were isolated. Seizures developed in 42% of cases, mostly in the II phase of the disease. The most serious clinical problem are difficulties in the differentiation between involuntary movements of the type of complex moyclonia and atonic-myoclonic seizures. In the electrophysiological evaluation of use may be finding in EEG of triphasic sharp waves and spike-wave complexes, apart from generalized periodic discharges characteristic for SSPE. A greater possibility of differentiation between epileptic seizures and involuntary movements is opened by monitoring examination or 24-hour EEG recording.
