What’s going on inside? Possible mechanisms associated with physical activity and MND

Physical activity and MND – part 3

This is the final blog article in our trio of blogs that are looking at physical activity and MND. The first two have addressed the questions ‘did the amount of physical activity I undertook before my diagnosis cause my MND?’ and ‘can I continue with physical activity after my diagnosis, or will this make my MND worse?’

Despite the evidence reported by Visser and colleagues, which showed an increase of 6% in the risk of developing MND in people with high activity levels (discussed in the first of these blogs), there is limited evidence to support a relationship between physical activity and the development of MND, that is, what exactly is it about physical activity that would lead to MND-specific neurodegeneration. The available evidence tends to suggest it is more likely that there are other, as yet unidentified, factors associated with physical activity that might drive the risk. However, several credible explanations for how exercise could directly cause MND have been proposed and studied and we are going to take a more in-depth look at some of these here.Read More »
