Vestibular involvement in peripheral neuropathy: a review

Area of Science:

• Neurology
• Otolaryngology
• Neuroscience

Background:

• Peripheral neuropathies often involve cranial nerves, with auditory neuropathy being well-documented.
• Vestibular neuropathy, a related but less studied condition, affects the vestibular division of the eighth cranial nerve.
• Existing literature shows a significant gap in understanding vestibular nerve involvement in generalized neuropathies.

Purpose of the Study:

• To review the current literature on the involvement of the vestibular nerve in peripheral neuropathies.
• To highlight the prevalence and clinical significance of vestibular neuropathy.
• To provide background on neuropathies and vestibulocochlear nerve anatomy.

Main Methods:

• A comprehensive literature search was conducted.
• Included textbooks and peer-reviewed articles from online bibliographic databases.
• Focused on two major medical research databases.

Main Results:

• Vestibular involvement is a frequent and consistent finding across various peripheral neuropathies.
• Unsteadiness or ataxia disproportionate to somatosensory loss or muscle weakness suggests vestibular neuropathy.
• The review identified a commonality of vestibular involvement in neuropathies of diverse etiologies.

Conclusions:

• Vestibular neuropathy is a common condition associated with peripheral neuropathies.
• Recognizing vestibular neuropathy is essential for optimizing patient care and rehabilitation strategies.
• Further research and clinical attention to vestibular neuropathy are warranted.
