Auditory changes in multiple sclerosis (MS) are rare but treatable. This study details four cases, including the first reported instance of palinacousis, demonstrating successful individualized treatment for hearing dysfunction in MS patients.
Area of Science:
- Neurology
- Neuroimmunology
- Otolaryngology
Background:
- Auditory manifestations are less common presenting symptoms of multiple sclerosis (MS) compared to other neurological deficits.
- Hearing abnormalities in MS can significantly impact patient quality of life.
Purpose of the Study:
- To describe four cases of auditory dysfunction secondary to MS.
- To report the first known case of palinacousis (perseveration of hearing) in MS.
- To highlight individualized treatment strategies and their efficacy in managing MS-related hearing issues.
Main Methods:
- Case series analysis of four patients with auditory changes attributed to MS.
- Detailed characterization of initial complaints, diagnostic workup (including clinical examination, laboratory testing, and neuro-imaging).
- Documentation of specific, individualized treatment interventions for each patient.
Main Results:
- Successful remission of auditory symptoms in all four cases through tailored treatment regimens.
- Identification and description of palinacousis as a rare auditory manifestation of MS.
- Correlation of clinical findings, pathophysiologic mechanisms, and lesion localization with treatment outcomes.
Conclusions:
- Individualized treatment approaches are effective in managing auditory disturbances in MS.
- This case series exemplifies precision medicine in the context of neuroimmunologic disorders.
- Understanding the clinical manifestations and pathophysiology is crucial for strategic treatment planning in MS-related auditory dysfunction.
