Episodic Syndromes That May Be Associated with Migraine: Benign Paroxysmal Vertigo
摘要
Benign paroxysmal positional vertigo (BPPV) is a prevalent cause of episodic vertigo, often overlapping with vestibular migraine (VM), which is itself a frequent yet underdiagnosed condition in migraine patients. The shared vestibular symptoms of these disorders, including dizziness and vertigo, create diagnostic challenges and complicate management. This study explores the pathophysiology, diagnostic criteria, and treatment approaches for BPPV in the context of VM, emphasizing practical strategies to address their coexistence. Evidence suggests that interactions between the trigeminal and vestibular systems, coupled with neurotransmitter involvement, contribute to vestibular dysregulation. Differentiating between VM and BPPV requires thorough clinical assessment, incorporating maneuvers like Dix-Hallpike for BPPV and criteria established by the International Headache Society for VM. Effective management involves repositioning maneuvers for BPPV and prophylactic therapies such as beta-blockers, calcium channel blockers, anticonvulsants, and botulinum toxin for VM. Multimodal approaches, including vestibular rehabilitation, show promise in improving outcomes for patients with coexisting conditions.
