What is the main cause of motor neuron disease?

It’s caused by a problem with cells in the brain and nerves called motor neurones. These cells gradually stop working over time. It’s not known why this happens. Having a close relative with motor neurone disease, or a related condition called frontotemporal dementia, can sometimes mean you’re more likely to get it.

Can you prevent motor neuron disease?

Certain dietary factors, such as higher intake of antioxidants and vitamin E, have been shown, at least in some studies, to decrease the risk of MND. Interestingly, increased physical fitness and lower body mass index (BMI) have been shown to be associated with a higher risk of MND.

Who is most likely to get motor neuron disease?

The condition can affect adults of all ages, including teenagers, although this is extremely rare. It’s usually diagnosed in people over 40, but most people with the condition first develop symptoms in their 60s. It affects slightly more men than women.

How long does motor neurone disease take to develop?

The onset of symptoms varies but most commonly the disease is first recognized between 20 and 40 years of age. Generally, the disease progresses very slowly. Early symptoms may include tremor of outstretched hands, muscle cramps during physical activity, and muscle twitches.

Is motor neuron disease genetically inherited?

About 10% of MND is ‘familial’; that is, there is or has been more than one affected person in a family. The remaining 90% of people with MND are the only affected person in their family and are said to have ‘sporadic’ MND. People with familial MND have the disorder because of a mutation in a gene.

Where does motor neurone disease start?

Motor neurone disease is an uncommon condition that mainly affects people in their 60s and 70s, but it can affect adults of all ages. It’s caused by a problem with cells in the brain and nerves called motor neurones. These cells gradually stop working over time.

What are the chances of getting motor neuron disease?

The estimated lifetime risk of developing MND was approximately 1 in 350 for men and 1 in 500 for women.

Has anyone been cured of MND?

Motor neurone disease (MND) sees muscles waste away after a loss of nerve cells that control movement, speech and breathing. There is no effective treatment or cure and half of the 1,500 people diagnosed each year die within 24 months.

Is exercise good for motor neurone disease?

Physical exercise can help maintain or improve strength in the muscles not affected by MND, and maintain flexibility in muscles that are affected. It can help prevent stiffness in the joints. Physiotherapy may also help people with breathing difficulties to clear their chests and maintain lung capacity.

How long does MND take to kill?

Research has given us a greater understanding of MND but there is no cure, and no effective treatment. It kills a third of people within a year and more than half within two years of diagnosis. Although the disease will progress, symptoms can be managed to help achieve the best possible quality of life.

Is MND painful?

MND is generally not a painful condition, but muscle stiffness can be uncomfortable at times. Some people experienced twinges, aches and cramps.

Can stress cause motor neuron disease?

There is strong evidence that oxidative stress plays an important role in the pathogenesis of motor neurone disease (MND).

How long do you live with MND?

People with MND become increasingly disabled. Life expectancy after diagnosis is one to five years, with 10 per cent of people with MND living 10 years or more. The needs of people with MND are complex and vary from person to person.
