Hemiplegic Migraine as Cause For Motor Vehicle Collision: A Case Report

Abstract

Abstract Introduction: Hemiplegic migraine (HM) is a rare, heterogenous form of migraine characterized by unilateral weakness. This motor aura can present with reversible visual, sensory, and language deficits. HM can be difficult to diagnose due to overlapping presentation with other complex conditions such as multiple sclerosis, seizure disorders, and transient ischemic attack (TIA). Case Presentation: We describe a case of a 40 year old with asymptomatic COVID-19 infection who presented after a motor vehicle collision caused by HM consistent with left sided weakness and loss of consciousness. Conclusions: To date, this is the first description of a patient with known complex migraines to have a motor vehicle collision as a result of HM. The risk of HM-associated neurologic symptoms while driving poses a significant public safety concern. We suggest driving restrictions be considered in patients with HM when migraine aura is present. This case presents support to examine active infection with SARS-CoV-2 as a trigger for HM.
