摘要Background:Vestibular migraine(VM)is a common cause of dizziness that is underrecognized,under-diagnosed,and challenging to effectively treat.The prevalence,appropriate diagnostic workup,and therapies for VM in low-and lower-middle-income countries(LLMICs)remain understudied.The objective of this scoping review is to evaluate the current state of VM research in LLMICs.Methods:PubMed,Embase,and Web of Science databases were searched to execute a scoping review of VM.Keywords"vestibular diseases"and"vertigo"were used in combination with terms referring to LLMICs as defined by the World Bank.Title and abstract screening,full-text review,and data collection were conducted by two authors independently.Results:Twenty-six studies were included in the scoping review.Most studies were cross-sectional(57.7％)or case studies/series(23.1％)and were conducted in urban settings only(92.3％).Geographic distribution of studies was skewed,with 65.4％of articles originating from India.The prevalence of VM among clinic patients ranged from 0.3％to 33.3％.VM most frequently presented as headache,nausea and vomiting,and photophobia.Radiographic imaging,audiometry,and electronystagmography/video-nystagmography were the three most commonly utilized diagnostic modalities in the dizziness workup.The most studied pharmacotherapies included calcium channel blockers,followed by beta-blockers and antiepileptics.Case studies and series discussed less common VM pharmacotherapies,such as ayurvedic medicine.Conclusions:There is a need for more VM research in LLMICs,including innovative diagnostic approaches and therapies that can improve VM care globally.Equitable partnerships between LLMIC and high-income country researchers must expand vestibular research capacity and productivity in LLMICs.
