Magnets may help migraines
Migraine sufferers 'may benefit from magnet therapy'
A magnet device can be used to treat some types of migraine, new UK guidance advises.
The watchdog NICE says although there is limited evidence, transcranial magnetic stimulation (TMS) may help ease symptoms in some patients. It says that the procedure is still relatively new and that more date is needed about its long-term safety and efficacy. But it may be useful for patients for whom other treatments have failed.
Migraine is common - it affects about one in four women and one in 12 men in the UK.
There are several typres - with and without aura and with or without headache - and several treatment options, including common painkillers, such as paracetamol.
Although there is no cure for migraine, it is often possible to prevent or lessen the severity of attacks.
NICE recommends various medications, as well as acupuncture, and now also TMS, under the supervision of a specialist doctor - although it has not assessed whether it would be a cost effective therapy for the NHS.
TMS involves using a portable device that is placed on the scalp to deliver a bried magnetic pulse.
NICE says doctors and patents might wish to try TMS, but they should be aware about the treatment's uncertainties. Reduction in migrain symptoms may be moderate, it says.
Prof Peter Goadsby, chairman of the British Association for the Study of Headache, said many migraine patients stood to benefit from trying TMS. In a trial in 164 patients, TMS worked twice as well as sham or placebo therapy and about 40% were pain-free two hours after using the device.
Wendy Thomas, chief executive at the charity the Migraine Trust, said: "Huge numbers of sufferers find their lives blighted by migraine. We welcome NICE guidance that may help deliver brighter futures to many people for whom other treatments have not worked.
"What we say - Since we started to spread the word about magnotherapy back in 1997, we've had lots of feedback from customers who have tried magnotherapy and have reported that it has significantly reduced the number of migraines and/or reduced their severity. Everybody is different and will respond differently to magnotherapy, so really, there is only one way to find out if this could help you. All of our wristbands come with a money back guarantee, so maybe now is the time to try one?
