Abstract
OBJECTIVE: This study aimed to investigate the role of sex hormones in postmenopausal women with vestibular migraine. METHODS: This observational study included 242 female patients with vestibular migraine who were postmenopausal during April 2017 to December 2019. Serum levels of sex hormones, including estradiol, progesterone, testosterone, follicle-stimulating hormone, luteinizing hormone, and prolactin, were determined by radioimmunoassay. The duration and frequency (every month) of onset of vestibular migraine were recorded. The degree of vestibular migraine was measured by the visual analogue scale. RESULTS: Serum levels of estradiol, progesterone, and testosterone were significantly lower, while serum prolactin levels were significantly higher in postmenopausal patients with vestibular migraine compared with healthy controls. Serum estradiol levels were negatively correlated with the duration, frequency, and severity of onset of vestibular migraine. Patients with higher serum estradiol levels showed a longer disease-free survival time. CONCLUSION: Sex hormones are correlated with vestibular migraine in postmenopausal women. Additionally, estradiol levels are correlated with the duration, frequency, and severity of onset of vestibular migraine, as well as the disease-free survival time.
