Patients with migraine may exhibit higher prevalence of restless leg syndrome, fibromyalgia, and depressive symptoms compared with individuals not experiencing migraines, according to a study published in Neurological Sciences.
Patients with migraine (n=200) and healthy volunteer controls (n=200) were enrolled in this study. The presence of fibromyalgia and restless leg syndrome was determined by medical interview, and the Beck Depression Inventory and Beck Anxiety Inventory (BAI) were used to determine the frequency of depression and anxiety, respectively. Patients were asked whether they received treatment for their conditions, and investigators also questioned patients about relevant risk factors associated with restless leg syndrome, fibromyalgia, and depression/anxiety (eg, family history, polyneuropathy, Parkinson disease, caffeine use).
A greater percentage of patients in the migraine group were found to have restless leg syndrome compared with the control group (33% vs 9.5%, respectively; P =.0001). Restless leg syndrome was more frequent in patients with migraine with aura vs simple migraine (P =.001). The prevalence of a family history of restless leg syndrome as well as other risk factors for the disease were comparable in participants with and without migraine (family history: 24.2% vs 21.1%, respectively; P =.773; other risk factors: P =.638).
The frequency of fibromyalgia was higher in patients with vs without migraine (61% vs 10%, respectively; P =.0001), and more patients in the migraine group reported having depressive and anxiety symptoms compared with controls (depressive symptoms: 39% vs 13.5%, respectively; P =.0001; anxiety symptoms [BAI scores]: 33.83 vs 23.93, respectively; P =.0001). Patients with restless leg syndrome with and without migraine had comparable BAI scores (36.23 vs 32.80, respectively; P =.088).
Limitations of this study include the small number of patients and a reliance on interview and questionnaire data for determining conditions.
“Interviews focused on the symptoms of [restless leg syndrome], depression, and fibromyalgia with migraine patients may help to decide on the most appropriate treatment modality available,” concluded the study authors.
