About

A short ketogenic diet (KD) treatment can prevent migraine attacks and correct excessive cortical response. Here, investigators aim to prove if the KD-related changes of cortical excitability are primarily due to cerebral cortex activity or are modulated by the brainstem.

Through the stimulation of the right supraorbital division of the trigeminal nerve, there will be concurrently interictally recorded the nociceptive blink reflex (nBR) and the pain-related evoked potentials (PREP) in 18 migraineurs patients without aura before and after 1-month on KD, while in metabolic ketosis. nBR and PREP reflect distinct brain structures activation: the brainstem and the cerebral cortex respectively. It will be estimated nBR R2 component area-under-the-curve as well as PREP amplitude habituation as the slope of the linear regression between the 1st and the 2nd block of 5 averaged responses.
