Clinical characteristics of vestibular migraine patients based on Caloric Test.

This study looked at vestibular migraine (VM) patients and their caloric test results. Researchers analyzed data from 126 VM patients and 100 healthy individuals. They focused on three key measures: canal paresis (CP), directional preponderance (DP), and fixation index (FI). Patients were divided into two groups: during migraine attacks and between attacks. Results showed that the attack group had higher CP, DP, and FI values than the interictal group. Specifically, CP was 37.3% in the attack group compared to 13.5% in the interictal group. The interictal group also had higher values than healthy controls. Healthy individuals showed no abnormal results. These findings suggest that caloric tests can help identify vestibular dysfunction in VM patients. This can improve diagnosis and treatment strategies for those suffering from vestibular migraines. Clinical relevance: This research indicates that caloric tests can effectively assess vestibular dysfunction in patients with vestibular migraines.
