MND is uncommon but not rare. Recent statistics estimate there are over 2,000 people in Australia currently diagnosed with MND and every day 2 Australians are diagnosed with MND. The average age of onset is 50.
However about 10% of cases are inherited (familial) and the genetic fault of about 60% of these cases is now known in Australian families. The risk of developing MND over a lifetime is about 1 in 300 people, with the risk increasing steadily with age (Martin S, Al Khleifat A and Al-Chalabi A.
1 The incidence of MND in Western populations, including Australia, is about 2e3 per 100 000, with a national prevalence of about 8 per 100000. 2 Currently, 1500 Australian patients suffer from the disease.
There is a 1 in 300 risk of getting MND across a lifetime. It can affect adults of any age, but is more likely to affect people over 50.
Motor neurone is the world's third most common neuro-degenerative disorder and is more commonly seen in older people. Video Player is loading. This is a modal window.
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.
Nutrients. There is some evidence that motor neurones become more likely to develop MND because of a lack of nutrients. One form of such nutrients is a group of chemicals called 'neurotrophic factors' (meaning 'nerve nourishing factors').
Researchers have hypothesized that vigorous physical activity might increase exposure to environmental toxins, facilitate the transport of toxins to the brain, increase the absorption of toxins, or increase the athlete''''s susceptibility to motor neuron disease through added physical stress.
There are treatments that can help people with MND, but there is no cure. It can reduce life expectancy significantly and eventually leads to death. The condition gradually worsens over time, and things like moving around, swallowing, and breathing become more difficult.
Inherited MND affects up to 1 in 10 people with MND and means they probably have a family history of the disease. Where this is the case, it is impossible to predict when or if a family history means MND will happen. Other triggers may still be needed for the disease to begin.
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.
In 2019, age-standardized DALY rate were 12.66 (95% UI, 11.98–13.29) per 100,000 population and age-standardized death rate were 0.48 (95% UI, 0.45–0.51) per 100,000 person-years associated with MND around the world.
This study adds to the evidence that repeated head injury with concussion, playing sports in general, and playing football (soccer) in particular, are associated with an increased risk of MND.
Motor neuron disease (MND) is a fatal neurodegenerative disease caused by both genetic and environmental factors, many of which remain to be elucidated. Worldwide MND incidence and prevalence have been shown to be increasing in the last decades.
Those carrying a fault in a gene leading to MND have a 50 percent (one in two) chance of passing the genetic error on to their children. However, the risk of someone carrying the faulty gene actually developing MND may be lower than 50 percent in some cases.
Generally, MND is believed to be caused because of a combination of environmental, lifestyle and genetic factors. Most cases of MND develop without an obvious cause. Around 1 in 10 cases are 'familial', meaning the condition is inherited. This is due to a genetic mutation, or an error in the gene.
Is MND painful? Motor neurones do not transmit or modify pain signals, so the disease itself is not inherently painful. 2 However, pain may be experienced as the disease progresses. Pain may occur at any stage of MND, including early on, with no relationship between pain intensity and length of time since diagnosis.
You are considered at risk with COVID-19 if you have a chronic neurological disease, such as motor neurone disease (MND). New strains of COVID-19: these pass on more easily, but are not thought to cause a higher risk of complications.
There is strong evidence that oxidative stress plays an important role in the pathogenesis of motor neurone disease (MND).
The research from the University of Sheffield, published in the journal EBioMedicine, suggests a causal relationship between exercise and MND, with high intensity physical activity likely to contribute to motor neurone injury in people who have a predisposing genetic profile.
MND is not a common disease. It affects adults and sometimes younger adults. You are likely to be more than 40 years old at diagnosis, and most people with MND are aged between 50 and 70. Men are affected almost twice as often as women, but this varies.
Classical ALS phenotype of MND
Despite this, and the clinical variability discussed above, the misdiagnosis rate for MND is relatively low at 7–8%.
Living With a Motor Neuron Disease
Some are milder and progress more slowly than others. Although there is no cure for motor neuron diseases, medicines and therapy can ease symptoms and improve your quality of life.
A new drug, called Amantadine Hydrochloride, was added to the trial in April 2023. New drugs will be selected for investigation in MND-SMART based on continuous review of constantly updated scientific evidence as well as findings from state-of-the-art human stem cell based drug discovery platforms.
