How magnets are altering drugs

Cleopatra could have recognized a factor or 2 in regards to the therapeutic energy of magnets. History books hint magnetic remedy again to the Egyptian queen, and the traditional Greeks used them to treatment all the pieces from aches and pains to illnesses.

Today, magnetic remedy remains to be used to deal with a variety of well being points. It’s typically related to easing osteoarthritic ache, however the jury’s nonetheless out on whether or not it really works. What science has confirmed, nonetheless, is magnetic remedy’s effectiveness at treating depression, migraines and coronary heart arrhythmias, and there is additionally new hope for these dwelling with a number of sclerosis. We take a look at the advances the medical consultants are enthusiastic about.

Multiple sclerosis

Magnets could maintain the important thing to slowing the progress of multiple sclerosis (MS), a situation of the central nervous system through which there is a lack of myelin, the insulating layer round nerve fibres within the mind and spinal twine.

When myelin is misplaced it results in signs equivalent to muscular spasms, issues with stability and arm and leg perform, pins and needles, and reminiscence loss.

More than 23,000 Australians have MS, with most recognized between the ages of 20 and 40.

Australian MS researcher Dr Kaylene Young is exploring how a painless process referred to as transcranial magnetic stimulation (TMS) might restore myelin and so cut back the results of MS.

It entails a round magnetic coil being positioned simply above the pinnacle, the place it produces light magnetic stimulation to the mind.

This triggers new insulating cells to develop and wrap round nerve fibres. While its potential as an MS remedy has up to now solely been examined on mice, Young says the outcomes have been encouraging.

“The treatment speeds up cell maturation, increases their survival and increases the insulation laid down,” she says, including that she plans to conduct human trials at Royal Hobart Hospital subsequent yr.

“At the moment, there’s nothing to promote brain repair for people with MS,” she explains. “If we can use this treatment, the long-term damage of MS could be a lot less and people could live normal lives.”

Wonky tooth

Magnets have been utilized in dentistry for 40 years, particularly in the case of maintaining dentures in place. For this, a magnet is positioned within the bone the place the dentures will likely be fitted, then the opposing pole magnets are positioned within the dentures. The magnets entice, maintaining them firmly in place.

Small magnets have additionally been used to carry jaw and face prostheses in place following most cancers surgical procedure.

Magnets at the moment are getting used for orthodontics to assist straighten and area tooth. These ‘magnetic dental attachments’ – that are being utilized by some orthodontists in Australia – are much more discrete than the normal braces many people needed to put on.

“The magnets used in orthodontics attract the teeth, or push them away from each other, using magnetic force,” Dr Scott Davis of the Australian Dental Association says. “This means you do not want cumbersome springs, bands or wires.


In the UK and US, magnets and TMS are getting used to deal with migraines. A research by TMS system producer Neuralieve discovered that 74 per cent of customers had success utilizing the remedy to relieve a migraine, experiencing little to no ache 2 hours later, with related reductions in gentle and sound sensitivity.

In Australia, about 15 per cent of individuals undergo a migraine at some point of their life. At the second, TMS for migraine is not being utilized in Australia.

TMS units have been accredited as a remedy for migraines by the National Institute for Health and Care Excellence within the UK, and by the Food and Drug Administration within the US.

“This is a breakthrough remedy for individuals who cannot tolerate or do not reply to present remedy, and it opens the door for a brand new period in treating migraine complications,” Dr Fayyaz Ahmed of The Migraine Trust within the UK says.

Irregular heartbeats

Abnormal coronary heart rhythms – arrhythmias – have an effect on about 5 per cent of girls and 6 per cent of males of their mid-50s and above. The electrical indicators that coordinate our heartbeat grow to be dysfunctional so the guts beats too quick, too slowly or irregularly.

This could cause fatigue, dizziness and shortness of breath.

In the US and UK, researchers are investigating a cutting-edge magnetic navigation system to hold out a remedy referred to as catheter ablation. Usually, a catheter is manually manipulated because it’s inserted into the affected person and used to scar small areas of coronary heart tissue to cease the defective indicators. The new remedy makes use of magnetic catheters that may higher entry hard-to-reach and delicate areas within the coronary heart.

“Catheters with magnetic properties aren’t extensively utilized in cardiovascular drugs but however they are often higher at negotiating difficult bends within the coronary heart,” Professor Garry Jennings, chief medical advisor of the Heart Foundation, says.

And, he provides, magnets produce other advantages for coronary heart remedy:

“We additionally use them for programming pacemakers.

They reply to electrical impulses or magnetic fields and we use exterior magnets to vary the speed as wanted.”

Magnets trialled for sleep apnoea

Each morning, hundreds of Australians get up after an evening of damaged sleep attributable to obstructive sleep apnoea. Standard remedy is a machine related to a face masks through a tube that lightly pumps air down the throat to maintain the airways open. But a brand new possibility could possibly be on the horizon, with trials within the US of a tool referred to as Magnap that makes use of magnets to carry the airways open at evening. A small magnet is positioned below the pores and skin of the neck through a small incision. While asleep, sufferers put on a neck collar containing an opposing pole magnet that draws the implanted magnet and retains the airways open.


When remedy and psychological therapies do not work, magnets will help some folks handle despair.

TMS is used to create a magnetic area that stimulates a small space of the mind concerned with regulating temper.

Dr Stephen Carbone from Beyondblue says the remedy takes about 15-30 minutes a day for 3 to 4 weeks.

“TMS induces a change within the electrical circuitry of the mind and this modifications the chemistry and the best way the mind cells discuss to one another,” he explains.

TMS was first trialled as a remedy for despair in Australia in 1997, nevertheless it’s principally utilized in non-public hospitals and clinics as the prices aren’t lined by Medicare as but.

“No remedy for despair is ideal however TMS has a spot for individuals who do not get higher with normal remedy procedures,” Carbone says. “It’s fairly easy, it would not require any anaesthetic and it has no main uncomfortable side effects.

When folks do reply to remedy, it actually can change their life.”
