Summary
Subacute sclerosing panencephalitis (SSPE) diagnosis can be improved by recognizing atypical EEG patterns. Early identification of these features aids timely management and prevents misdiagnosis of SSPE.
Area of Science:
- Neurology
- Pediatric Neurology
- Neurophysiology
Background:
- Subacute sclerosing panencephalitis (SSPE) is a rare, progressive neurological disorder.
- Early diagnosis is crucial for managing SSPE and preventing long-term complications.
Purpose of the Study:
- To identify and define atypical clinical and electroencephalogram (EEG) features of SSPE.
- To provide an overview for differential diagnosis of SSPE.
Main Methods:
- Retrospective analysis of 66 EEGs from 53 patients with serologically confirmed SSPE.
- Inclusion of sleep-waking EEGs/video-EEG records (≥2 hours) and cranial MRIs.
Main Results:
- Epileptogenic activities detected in 83% of EEGs, predominantly in frontal regions.
- Epilepsy diagnosed in 43% of patients, with generalized tonic-clonic seizures being most common.
- Uncommon EEG findings included unilateral/bilateral diffuse paroxysmal discharges in 59% of EEGs.
Conclusions:
- Recognizing uncommon clinical and EEG findings in SSPE is vital, especially in regions where SSPE is not eradicated.
- Improved diagnostic accuracy can prevent misdiagnosis and delays in managing treatable SSPE cases.
