To demonstrate that the elevated prevalence of migraine in patients with vertigo disorders is due to enhanced sensitivity to dizziness, which could cause migraineurs to seek more, or earlier, medical care for vertigo disorders, confounding the ability to show causation.
This case-control study investigated whether migraineurs perceive dizziness more intensely than non-migraineurs by comparing caloric responses in migraineurs, non-migraineurs and possible migraineurs. The summed caloric responses in the best responding ear were reviewed.
The migraine group had higher caloric response values, with a mean of 37.97 degrees per second, which was statistically significant when compared to the values for the possible migraine group (30.74 degrees per second (p < 0.05)) and the non-migraine group (30.70 degrees per second (p < 0.001)).
The findings suggest that migraineurs experience vestibular stimuli more intensely compared to non-migraineurs, which might explain the association of migraine with vestibular disorders in general.
证明眩晕症患者中偏头痛患病率升高是由于对头晕的敏感性增强，这可能导致偏头痛患者因眩晕症寻求更多或更早的医疗护理，从而混淆了因果关系的显示能力。
这项病例对照研究通过比较偏头痛患者、非偏头痛患者和可能患有偏头痛的患者的冷热试验反应，调查偏头痛患者是否比非偏头痛患者对头晕的感知更强烈。对反应最佳耳朵的冷热试验反应总和进行了评估。
偏头痛组的冷热试验反应值更高，平均每秒37.97度，与可能患有偏头痛的组（每秒30.74度（p < 0.05））和非偏头痛组（每秒30.70度（p < 0.001））相比，具有统计学意义。
研究结果表明，与非偏头痛患者相比，偏头痛患者对前庭刺激的体验更强烈，这可能总体上解释了偏头痛与前庭疾病的关联。
