The goal of this clinical trial is to study and describe the effects of bilateral tDCS applied to dorso-lateral-prefrontal cortex (DLPC) in patients with drug-resistant migraine in terms of reduction in frequency of pain, impact of pain in daily life, quality of sleep and psychological measures. We finally planned to include high frequency and chronic migraine patients. The main questions it aims to answer are: * Will bilateral DLPC tDCS be feasible, well tolerated and safe in drug resistant migraine patients? * Will bilateral DLPC tDCS be effective in reducing pain frequency, intensity and its impact in daily life activities? * Will bilateral DLPC tDCS be effective in ameliorating sleep and psychological associated symptoms? * Will bilateral DLPC tDCS be such effective in reducing pain frequency, intensity and its impact in daily life activities as anti-CGRP treatments? Participants will undergo 2 tDCS sessions daily for 2 consecutive weeks. Patients will be blinded to treatment and will be divided in two groups (real vs placebo). A third group of patients, age-matched to the other two, will undergo anti-CGRP treatment. Patients will be asked to complete Patient-Reported Outcomes (PROMs) scales at baseline, one week after the end of the treatment and at 6 months after the end of the treatment. Researchers (blinded to the treatment) will compare the group that underwent real tDCS treatment vs the one that underwent placebo tDCS vs the one that underwent anti-CGRP drugs to see if bilateral DLPC tDCS is effective in reducing migraine frequency, intensity and impact and if bilateral DLPC tDCS is such effective as anti-CGRP treatment.

TDCS was delivered by a DC-Stimulator (Newronika, Italy) over both DLPC. The electrodes (35 cm2) were soaked in 0.9% NaCl. The anode was positioned on the left dorsolateral prefrontal cortex and the cathode on the right dorsolateral prefrontal cortex.
CGRP-mAbs have been the first target-driven treatment to be approved for migraine prevention. Their efficacy and safety have been demonstrated in randomized controlled trials (RCT) as well as, in real-world evidence (RWE) studies
Clinica de Intervencion en Neurociencias
Talavera de la Reina, Toledo, Spain
Migraine attacks monthly frequency
Patients will report migraine monthly frequency for the 3 different time-points
Time frame: baseline, 2 weeks after the end of the treatment, 6 months
Headache Impact Test (HIT-6) score
HIT-6 is a tool used to measure the impact headaches have on patient's ability to function on the job, at school, at home and in social situations.
Time frame: baseline, 2 weeks after the end of the treatment, 6 months
Pain killer drugs monthly taken
Patients will report pain-killer drugs taken during a month for the 3 different time-points
Time frame: baseline, 2 weeks after the end of the treatment, 6 months
The Pittsburgh Sleep Quality Index (PSQI)
PSQI is a self-report questionnaire that assesses sleep quality over a 1-month time interval. The measure consists of 19 individual items, creating 7 components that produce one global score, and takes 5-10 minutes to complete.
Time frame: baseline, 2 weeks after the end of the treatment, 6 months
Brief Symptom Inventory (BSI)
The Brief Symptom Inventory (BSI) consists of 53 items covering nine symptom dimensions: Somatization, Obsession-Compulsion, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic anxiety, Paranoid ideation and Psychoticism; and three global indices of distress: Global Severity Index, Positive Symptom Distress Index, and Positive Symptom Total. The global indices measure current or past level of symptomatology, intensity of symptoms, and number of reported symptoms, respectively.
Time frame: baseline, 2 weeks after the end of the treatment, 6 months
