Summary
Multiple sclerosis (MS) patients show audiovestibular changes. Auditory brain stem response and VEMP tests help monitor MS evolution alongside MRI scans.
Area of Science:
- Neurology
- Neuroscience
- Audiology
Background:
- Multiple sclerosis (MS) is a central nervous system demyelinating disease.
- MS is characterized by plaques causing variable neurologic dysfunction.
- Audiovestibular dysfunction is a known complication of MS.
Observation:
- A 20-year-old woman with MS presented with audiovestibular symptoms.
- Pre-treatment tests revealed bilateral auditory brain stem response (ABR) prolongation, right ear canal paresis, absent right ear VEMP, and delayed left ear VEMP.
- MRI showed multiple demyelinating lesions in the brain and cerebellum.
Findings:
- After treatment, MRI showed spontaneous resolution of demyelinating plaques.
- Caloric responses were expected to recover.
- ABRs remained prolonged bilaterally, while VEMP showed a normal right ear and delayed left ear response post-treatment.
Implications:
- MRI, caloric tests, ABR, and VEMP are valuable for monitoring MS progression.
- These tests aid in assessing audiovestibular function evolution in MS patients.
- Understanding audiovestibular changes is crucial for comprehensive MS patient care.
