Motor neurone disease (MND) is a neurodegenerative disease that causes rapidly progressive muscle weakness and eventually results in paralysis. MND causes muscle wasting which means limbs will become weaker over time. Muscle weakness. It is thought that MND is caused by a mix of genetic and environmental factors, and several possible factors have been suggested, including exposure to chemicals, fractures and injuries, smoking, military service, and engaging in some sports or high levels of exercise, but research studies have so far failed to find clear conclusive evidence. The messages allow people to make voluntary movements like walking, swallowing, talking and breathing. EMND affects lower motor neurons, interfering with neurological input into muscles. As these nerve cells die off the body can no longer activate these muscles, causing them to weaken and waste away. These can appear in a different order for each individual, but you may be diagnosed with a particular type of MND, due to the way symptoms present. the NHS has outlined the following seven symptoms patients can expect in the final stages of the disease.
