Clinical and Neurophysiological Effects of tDCS to Visual and Motor Cortex in Migraine

tDCS can be offered as an alternative to migraine patients who have frequent and severe attacks and who are resistant to or unresponsive to preventive drug therapy. Additionally, this technique may also be an option for patients who refuse or have contraindications to taking anti-migraine medications. A decrease in headache severity and frequency is expected with this neuromodulation applied to migraine patients with frequent attacks. Based on this hypothesis; This tested whether simultaneous modulation of motor (M1, left) and visual cortex (O1 or O2, ipsilateral) with tDCS applied for 3 consecutive days is an effective treatment for migraine patients for the following specific purposes . No significant undesirable effects are expected, except for possible side effects that are simple and do not require medical intervention, such as tingling or itching in the area where the electrodes are attached, moderate fatigue, mild headache, nausea at a rate of less than 3%, and insomnia at a rate of less than 1%. . The research will be conducted within the framework of ethical principles and in accordance with the good clinical practice protocol. A) The primary purpose of this study is to determine whether transcranial direct current stimulation applied simultaneously to the motor and visual cortex in migraine patients provides a significant reduction in pain due to migraine attacks compared to sham tDCS. Additionally, to evaluate the effects of this treatment, They will be measured changes in the number of migraine attacks, abortive medication intake (e.g., opioids, triptans), as well as overall improvement in cognitive status and quality of life. In addition, electrophysiological EEG evaluations, before and after treatment, and the results of these measurements, as a potential biomarker in migraine, will be compared in the active and sham groups. B) It is aimed to determine whether the clinical effects of tDCS are long-lasting. Therefore, It will compared whether there is
