The Role of Left Prefrontal Transcranial Magnetic Stimulation in Episodic Migraine Prophylaxis
Episodic Migraine, Prophylaxis
About this trial
This is an interventional prevention trial for Episodic Migraine focused on measuring rTMS = repetitive transcranial magnetic stimulation, LDLPFC = Left dorsolateral prefrontal cortex, HIT 6 = Headache Impact test, NPRS = Numeric Pain Rating Scale, ICHD = The international classfication of Headache disorder, MT= Motor threshold

Receiving repetitive transcranial magnetic stimulation (rTMS)
Group receiving placebo rTMS
This group received 5 rTMS sessions, delivered over one week over the left dorsolateral prefrontal cortex (LDLPFC ) at 5-Hz frequency and 100% motor threshold intensity.
This group received Placebo rTMS was given with the same stimulation frequency at a fixed intensity of 50% of the machine output
