A new pocket-sized wearable device is available to help treat and prevent migraine headaches.

Cefaly Technology has released the Cefaly II, an updated version of the Cefaly I, which is worn over the forehead like a headband and uses small electrical impulses to stimulate the trigeminal nerve, which has been associated with migraine headaches.

The Cefaly II is much smaller and fits in the palm of a hand. Like its predecessor, the device is worn on the forehead, but is held more securely in place by a magnet. Because of its smaller size, the manufacturer believes the Cefaly II will be more accessible and easier to use.

“This compact device is so easy to tuck in a pocket or purse and I am hopeful it will further increase compliance and bring an even larger reduction in migraine attacks to patients,” said Dr. Pierre Rigaux, Chief Executive Officer of Belgium-based Cefaly Technology.

“Now that the device is so small, it’s a big deal because patients can have their Cefaly II with them wherever they go, which means they’ll be able to use it more readily, at their most convenient time.”

The Cefaly II uses a magnet to attach itself to a self-adhesive electrode worn directly on the forehead. The rechargeable, battery powered device sends tiny electrical impulses through the skin to desensitize the upper branches of the trigeminal nerve and reduce the frequency of migraine attacks. Patients have full control of their daily 20-minute session and can ramp up the intensity to their own comfort level.

In a small study of 20 migraine sufferers, published in The Journal of Headache and Pain, the Cefaly I provided "statistically significant" pain relief and an 81 percent reduction in the number of migraine attacks. Patients in the study also said they used significantly less migraine medication.

The electrode and output of the Cefaly II is identical to the Cefaly I, according to the company.

Here’s a company produced video of how the Cefaly II works:

The Cefaly II is only available by prescription and costs $349, with a 60-day money back guarantee. The device can be ordered online by clicking here. The Cefaly I will no longer be offered, but the electrodes for it will be available for another 5 years. Cefaly Technology has sold about 20,000 of the devices in United States and 80,000 outside the U.S.

Migraine is thought to affect a billion people worldwide and about 36 million adults in the United States, according to the American Migraine Foundation. It affects three times as many women as men. In addition to headache pain and nausea, migraine can also cause vomiting, blurriness or visual disturbances, and sensitivity to light and sound.
