Abnormalities of the acoustic reflex in multiple sclerosis

Area of Science:

• Neurology
• Audiology
• Neuroscience

Background:

• Multiple sclerosis (MS) is a chronic neurological disease.
• Acoustic reflex testing assesses auditory pathway function.
• Understanding MS-related auditory changes is crucial.

Purpose of the Study:

• To investigate acoustic reflex morphology in patients with definite multiple sclerosis.
• To identify common patterns of acoustic reflex abnormalities in MS.

Main Methods:

• Evaluated acoustic reflect morphology in 122 patients diagnosed with definite multiple sclerosis.
• Analyzed various dimensions of acoustic reflex morphology.

Main Results:

• 75% of the study population exhibited abnormalities in acoustic reflex morphology.
• The most common abnormality involved alterations in relative amplitude indices (afferent, efferent, central pathway).
• Other observed abnormalities included delayed latencies, reduced amplitude, and elevated thresholds.

Conclusions:

• Acoustic reflex morphology is frequently abnormal in multiple sclerosis.
• Alterations in amplitude indices are particularly prevalent in MS patients.
• Acoustic reflex testing may serve as a valuable tool for assessing neurological function in MS.
