Transcranial Direct Current Stimulation of the Occipital Cortex in Medication Overuse Headache: A Pilot Randomized Controlled Cross-Over Study
Mansour et al., 2020. Journal of Clinical Medicine
- Migraine days and severe migraine days per week decreased after 3 consecutive days of tDCS in patients with medication overuse headache.
- Occipital tDCS kept the benefit for 2 weeks, while the effect of prefrontal tDCS lasted only 1 week.
- Only occipital tDCS reduced daily use of pain medication, at both weeks 1 and 2.
- Sessions were given with Sooma tDCS, and no patients withdrew because of side effects.
- Cathodal occipital tDCS is suggested to improve clinical outcomes in medication overuse headache, but larger trials are needed.
