Cefaly

Cefaly is an external cranial neurostimulator indicated for the treatment and prevention of migraine and tension headaches. Cefaly is intended for patients who suffer from frequent severe migraines or headaches, especially when drugs consumption is to be reduced. The Cefaly technology can also be used in order to produce a sedative effect.

Biomedical principles
Cefaly is an electronic medical device that produces electrical micro-impulses. These pulses are intented to trigger excitations, i.e. action potentials on the nerve fibres of either the superior branch of the trigeminal nerve via an electrode placed on the forehead, or of the major occipital nerve (Arnold’s nerve) via a occipital electrode.

Neurostimulation
Cranial neurostimulation has generally been used with implantable devices similar to pacemakers. Cefaly’s great advantage is to allow this neurostimulation technique to be used in an external way that does not require any surgery as opposed to implanted devices. This external cranial neurostimulation technology is made possible thanks to the high specificity and precision of the electrical micro-impulses able to trigger the excitation of the focused nerve fibres (axons) without causing strong pain in cranial periosteum. Many recent studies have demonstrated the high safety and the efficacy of the Cefaly for the migraine treatment and prevention
