[Vascular mechanisms in Meniere's disease]

Area of Science:

• Neurology
• Otolaryngology

Background:

• Meniere's disease (MD) is a chronic condition linked to endolymphatic hydrops with unknown causes.
• Vascular factors are increasingly implicated in MD pathogenesis.

Purpose of the Study:

• To review the potential vascular mechanisms contributing to Meniere's disease.
• To explore the relationship between Meniere's disease and migraine.

Main Methods:

• Literature review focusing on vascular aspects of Meniere's disease.
• Analysis of comorbidity data between Meniere's disease and migraine.

Main Results:

• Vascular dysregulation, labyrinthine ischemia, and venous drainage issues may cause endolymphatic hydrops.
• High comorbidity suggests a potential shared trigeminovascular dysfunction in MD and migraine.

Conclusions:

• Vascular mechanisms are critical in Meniere's disease.
• Further research into trigeminovascular dysfunction and vascular treatments like betahistine is warranted.
