Vestibular vertigo. A form of polyneuritis?

Area of Science:

• Neurology
• Otolaryngology
• Virology

Background:

• Vestibular vertigo is often attributed to viral infections.
• Specific forms like acute vestibular neuronitis may represent viral cranial polyneuritis.

Purpose of the Study:

• To investigate the hypothesis that acute vestibular vertigo is a manifestation of viral cranial polyneuritis.
• To assess otoneurologic signs and viral titers in vertigo patients.

Main Methods:

• Evaluated 16 patients with acute vertigo for otoneurologic signs and serum complement-fixation titers to herpes simplex and herpes zoster.
• Compared findings with 100 control subjects without otoneurologic issues.
• Monitored patients during acute attacks and several weeks post-onset.

Main Results:

• All vertigo patients exhibited vestibular nerve abnormalities.
• Additionally, all patients showed transient cranial nerve abnormalities that resolved within four weeks.
• Serum titers were analyzed, though specific results are pending further investigation.

Conclusions:

• Transient acute cranial nerve abnormalities in vestibular vertigo patients support the concept of inflammatory polyneuritis.
• Preliminary findings suggest that anti-inflammatory agents, such as prednisone, may be an effective treatment modality.
