Electrophysiological (BAEPs) changes in subacute sclerosing panencephalitis.
Acta Neurologica Belgica
|March 1, 1984
Summary
Brainstem auditory evoked potentials (BAEPs) revealed abnormalities in subacute sclerosing panencephalitis (SSPE) that correlated with clinical status. Increased III-V interpeak latencies suggest potential CNS lesions or endogenous factors.
Area of Science:
- Neurology
- Neurophysiology
Background:
- Subacute sclerosing panencephalitis (SSPE) is a rare, progressive neurological disorder.
- Brainstem auditory evoked potentials (BAEPs) assess the integrity of the auditory pathway in the brainstem.
Observation:
- A case study of SSPE was monitored using BAEPs over time.
- Electrophysiological alterations, specifically increased III-V interpeak latencies, were observed.
Findings:
- BAEP abnormalities in SSPE were linked to the patient's clinical presentation.
- These abnormalities lessened during periods of clinical improvement.
- Pathological increases in III-V interpeak latencies were a key finding.
Implications:
- BAEPs can serve as a valuable tool for monitoring SSPE progression.
- Findings suggest BAEP alterations may reflect endogenous factors like edema or focal viral CNS lesions.
