This study found significant sex differences in spontaneous cervical artery dissection (SCAD). Men had higher rates of hypertension, while women experienced more frequent multiple dissections, migraine, and tinnitus, with similar outcomes for both sexes.

Area of Science:

  • Neurology
  • Vascular Medicine
  • Epidemiology

Background:

  • Spontaneous cervical artery dissection (SCAD) is a significant cause of stroke, particularly in younger adults.
  • Understanding sex-specific differences in SCAD is crucial for targeted prevention and treatment strategies.

Purpose of the Study:

  • To investigate and delineate the distinct clinical characteristics and risk factors between men and women diagnosed with spontaneous cervical artery dissection.
  • To identify potential sex-based disparities in the presentation and associated comorbidities of SCAD.

Main Methods:

  • Retrospective analysis of a cohort of 696 patients diagnosed with spontaneous cervical artery dissection.
  • Comparison of demographic data, clinical presentation, comorbidities, and outcomes between male and female patient groups.

  • Statistical analysis to determine the significance of observed differences (p-values provided).

    • Main Results:

    • A higher proportion of men (n = 399) were identified in the study cohort.
    • Men exhibited a significantly higher prevalence of hypertension (31% vs. 15%, p < 0.0001).
    • Women were younger on average and presented more frequently with multiple dissections (18% vs. 10%, p = 0.001), migraine (47% vs. 20%, p < 0.0001), and tinnitus (16% vs. 8%, p = 0.001).

    Conclusions:

    • Significant sex-based differences exist in the clinical presentation and associated conditions of spontaneous cervical artery dissection.
    • While hypertension is more common in men with SCAD, women are more likely to experience multiple dissections and specific neurological symptoms like migraine and tinnitus.
    • Despite these differences, the overall outcome and mortality rates for SCAD were comparable between sexes.
