Cervical Vertigo: Historical Reviews and Advances

Area of Science:

• Neurology
• Orthopedics
• Otolaryngology

Background:

• Vertigo is a common patient presentation.
• Cervical vertigo, a debated cause of vertigo, has evolving theories regarding its origin.
• Early hypotheses linked it to cervical sympathetic nerves, but this is now largely discounted.

Observation:

• Abnormal sensory input from damaged upper cervical joint receptors was proposed as a cause.
• Further research indicates diseased cervical intervertebral discs are a likely source.
• Ingrowth of Ruffini corpuscles into diseased cervical discs is a recent finding associated with cervical vertigo.

Findings:

• Abnormal neck proprioception from Ruffini corpuscles in diseased discs and muscle spindles in tense neck muscles is implicated.
• This aberrant input is transmitted to the central nervous system.
• A sensory mismatch occurs between cervical signals and vestibular/other sensory information, causing vertigo.

Implications:

• Understanding the complex pathophysiology of cervical vertigo is crucial for diagnosis and management.
• Further research is needed to elucidate the exact mechanisms.
• This may lead to improved treatment strategies for patients experiencing vertigo related to neck conditions.
