Adding a bit from the Irish Motor Neuron Disease Association to explain what MND is:
What Is MND?
Motor Neurone Disease (MND) is a progressive neurological condition that attacks the motor neurones, or nerves, in the brain and spinal cord. This means messages gradually stop reaching the muscles, which leads to weakness and wasting.
MND can affect how you walk, talk, eat, drink and breathe. However, not all symptoms necessarily happen to everyone and it is unlikely they will all develop at the same time, or in any specific order.
The cause of MND is not known. There may be environmental factors that trigger the damage in people who are susceptible to the disease. On going research is necessary to find out the nature of these environmental factors, and what makes one person more susceptible than another.
MND strikes people of all ages and currently there is no cure, however symptoms can be managed to help the person achieve the best possible quality of life. The drug Riluzole (Rilutek) has shown to be helpful in slowing down the progress of the disease.
