Cefaly is an External Trigeminal Nerve Stimulation device (e-TNS) for migraine treatment. A self-adhesive electrode is placed on the forehead and the Cefaly device is magnetically connected to this electrode. Precise micro-impulses are then sent through the electrode to the upper branch of the trigeminal nerve to either relieve the headache pain during a migraine attack (Acute setting) or to prevent future migraine attacks (Prevent setting).
Who is Cefaly for? Cefaly is intended for patients who suffer from migraine with or without aura particularly when drug consumption needs to be reduced.
The Acute setting is indicated for the acute treatment of migraine attacks.
The Prevent setting is indicated for migraineurs who have frequent attacks (3 or more per month) and need a migraine prophylaxis to reduce the frequency of attacks.
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.
