Researchers proposed a new solution for people suffering
from chronic migraines: a magnetic device that could replace classic
medication, and solve the problems of millions of people who’ve become intractable
to medical therapies.
How does a world without migraines sound? For some, who’ve
experienced excruciating headaches, nothing sounds better. The latest research
in the field suggests that people suffering from migraines will be able to
alleviate their pain without any medication.
The solution is a hand-held magnetic device that while held
against the back of the head, is able to send magnetic pulses capable of
short-circuiting the pain signals sent to the brain.
A typical migraine can last anything from 4 to 72 hours, and
sometimes can be accompanied by nausea and vomiting. While the exact causes
remain unknown, the migraine is often treated with prescription medication.
Approximately one third of the population is affected by
migraine at one point in their life; the prevalence is higher in females than
in males, however, that changes with age. Some people experience a more severe
form of migraine, called migraine with aura, which consists of neurological
phenomena that accompanies the attack, such as disturbance in vision, olfactory
hallucinations and sometimes even paresthesia.
Migraines have also been linked with an increased
cardiovascular risk: the risk of stroke is two to three times increased in
migraine sufferers. The risk is particularly increased in women who use oral
contraceptives, researchers warned.
The regular treatment consists of painkillers, but for those
who can’t stand taking medication, the new device might offer a useful
alternative.
Medtronic, the medical device maker, sponsored a study called
the Occipital Nerve Stimulation for the Treatment of Intractable Migraine
(ONSTIM), in which they collected data from 66 patients, who they followed for
three months.
According to Dr. Joel R. Saper, M.D., founder and director
of the Michigan Head Pain and Neurological Institute, occipital nerve
stimulation could prove to be the alternative therapy option for patients
suffering from chronic migraine.
The study consisted of planting thin lead wires under the
skin, near the occipital nerves, which were connected to a neurostimulator that
delivered controlled electrical pulses to the occipital nerves.
Patients were randomly divided into three groups: one group
received a neurostimulator, having the ability to control the level of
stimulation, others were given a neurostimulator as part of a device control
group, while the third group received standard medical treatment.
The occipital nerve stimulation therapy received a positive
response, with a 50 percent reduction in the number of headache days a month,
or a reduction in the pain intensity of three points on a 0-10 scale.
The effects of occipital nerve stimulation for chronic
migraine have not been fully studied yet, but according to Saper, the early
experience in the study was enough to prove that some chronic migraine patients
who have ran out of treatment options might benefit from it.
Approximately 28 million Americans suffer from migraines,
and 70 of them are women. The treatments available to date work in most cases,
however, 3 to 14 percent of people suffering from migraines become intractable
to medical therapies. According to Medtronic, these people could be perfect
candidates for the occipital nerve stimulation treatment.
The World Health Organization ranked severe migraine among
the highest seven disability classes, together with psychosis, dementia and
quadriplegia.
