TURSDAY June 26, 2008 (foodconsumer.org) -- Medtronic has
invented a device to treat migraines, which is claimed to be able to reduce monthly
episodes of headaches in a moderate percentage of patients who did not respond
to prescription medications by 50%, CNN reports.
Trial results to be presented Friday at this year's American
Headache Society annual meeting show that the pacemaker-like device did a
better job in alleviating pain in some migraine suffers than prescription
drugs.
The device is designed to be implanted in the back of the
neck to reduce pain associated with chronic migraines by sending electrical
impulses through the central nervous system.
Medtronic said in a statement that it tested its device in a
trial of 61 patients who experienced on average 15 or more headache days in a
month and whose condition did not respond to conventional medicine.
After three months, 39 percent of patients who used the
device and were able to control the pulses themselves experienced a 50 percent
or more reduction in the number of month headaches.
Among those who got the device, but were not able to adjust
it, only 6 percent experienced a positive effect.
In the control group of patients who did not get the device,
but took the standard migraine drugs, none achieved a 50 percent reduction.
Migraines are a condition associated with hormone fluctuation
more often occurring in women than men. The condition affects an estimated 28
million Americans.
CNN cited Medtronic
as saying that 3 to 14 percent of suffers are not responsive to medicine.
Migraines can be triggered by allergies, stress, smokes,
alcohol and certain foods including tyramine-containing foods such as aged
cheese, red wine and some beans and other foods like nuts, banana dairy products
among others.
