A prescription-only device for migraine treatment, Cefaly uses external trigeminal nerve stimulation, or e-TNS, to either relieve migraine pain or prevent a migraine from occurring.
Your trigeminal nerve is the largest of the 12 cranial nerves, and it transmits sensory information -- like pain -- to your brain. Cefaly, a self-adhesive device you wear between your eyes, aims to intercept pain signals along that nerve. If you think Cefaly might be right for you, talk to your doctor about a prescription.
This is the same sort of therapy used in the newly FDA-approved NeuroSigma, the first at-home medical device approved for treating ADHD in children.
