The Impact of Fibromyalgia on Disability, Anxiety, Depression, Sleep Disturbance, and Quality of Life in Patients with Migraine

The aim of the present study was to assess the impact of fibromyalgia (FM) comorbidity on disability, anxiety, depression, sleep disturbance, and quality of life in patients with migraine. Eighty-six consecutive migraine patients (age, 35.4±10.3 years; 69 women and 17 men) were enrolled in the study. The headache characteristics of the patients were recorded. FM was diagnosed based on the 1990 American College of Rheumatology classification criteria for the diagnosis of FM. All patients were asked to complete selfreport questionnaires, including the Fibromyalgia Impact Questionnaire (FIQ), Headache Impact Test (HIT-6), Migraine Disability Assessment Questionnaire (MIDAS), Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and the 36- Item Short Form Survey (SF-36) to assess their pain-related disability, migraine-related disability, depression, anxiety, sleep disturbance, and quality of life. Of the migraine patients, 28 (32.6%) met the criteria for FM. Migraine patients with FM showed significantly increased migraine frequency and BDI, BAI, and PSQI scores and decreased quality of life scores for all eight domains of the SF-36 compared to patients with migraine alone, whereas the mean HIT-6 and MIDAS values did not differ between the groups. FIQ score showed statistically significant positive correlations with BDI, BAI, PSQI, and MIDAS scores and with headache frequency (p
