Migraine is a primary headache with high prevalence in the general population but is considered a disabling medical condition. It is suggested that obesity is a risk factor for chronic migraine. Thus treatment with drugs, such as topiramate, which reduces pain and weight, is ideal for obese patients with migraine. The aim of this study was to evaluate the effects of topiramate on body composition in patients with chronic migraine and to verify whether these effects could be related to nutritional status. We studied 26 female patients with age ranging from 18 to 45 years with prophylactic treatment with topiramate (50 mg/day) for three months. Body composition indexes (body mass index, BMI; body fat, BF; fat-free mass, FFM) were obtained through anthropometric assessment. After treatment, topiramate reduced BMI (0,82 kg/m2) and in BF (3.3 %), but increased FFM (1.1 kg). When considering nutritional status, FFM was increased only in obese patients. In conclusion, our main finding is that besides the reduction in BMI and BF, topiramate led to an increase in FFM in overweight and obese patients. Our results open new perspectives for future studies on the relationship between body composition and migraine, indicating that more studies on this body compartment are needed, especially in patients with chronic migraine.
