How does the Cefaly work?
Most headaches and migraines involve the trigeminal nerve. Its superior branch ends at the exit of the eye socket, underneath the skin of the forehead.
Neurostimulation of the trigeminal nerve with:
- Cefaly acute setting (high frequency, single long session) produces a sedative effect on the nervous system that relieves headache pain.
- Cefaly prevent setting (low frequency, daily short sessions) restores progressively a normal metabolism in the fronto-temporal cortex of migraineurs; that is to say an improvement of the migraine-triggering threshold, which consequently reduces the frequency of migraine attacks.
