Professional football and MND – looking at the evidence

Last year professional football players, Len Johnrose and Stephen Darby, announced they’d been diagnosed with motor neurone disease (MND). This follows previous announcements from other prominent footballers in this country and across the world in recent years.

Is it the case that professional football players are more prone to developing MND than the general population? Or is this just the impression created by the high-profile nature of these professionals and the corresponding media coverage these cases bring? What does the science suggest?

Here we look at some of the studies that investigate the incidence (rate of newly diagnosed cases) of MND in professional football players and take a closer look at the suggested causes.Read More »

GLT8D1: new gene identifies novel disease mechanism

MND Association-supported clinical fellow Dr Johnathan Cooper-Knock, and a PhD student Tobias Moll, report mutations in a new MND gene which has uncovered a previously unknown disease mechanism. The new MND causing gene holds instructions for a class of proteins, called glycosyltransferase (GLT8D1), which has not previously been associated with neurodegeneration.

During the experiments, published in the journal Cell Reports, the research team read the genetic code from two related patients with an unknown familial (inherited) form of MND and found a change in the gene that makes an enzyme called GLT8D1. They went on to examine a larger sample of 103 people with inherited MND and found that five of these also had this gene abnormality, indicating that this change causes MND. Because the enzyme and its mechanism have never previously been associated with MND, this study has uncovered a new genetic and biological cause of the disease.Read More »

Disease mechanisms: Highlights from Glasgow

This blog is part of the ‘Highlights from Glasgow’ collection of articles, where you can read about the content of some of the talks and posters presented at the 29th International Symposium on ALS/MND.

Several sessions at the Symposium focused on how impairments in key neuronal structures in MND contribute to the development and progression of the disease, and how these could be targeted with therapeutics.

Prof Spires-Jones (C16) opened session 4A with a discussion of the role of synapses in neurodegeneration. Synapse dysfunction and loss is seen in many neurological diseases, including MND, Alzheimer’s disease and Dementia with Lewy bodies. The commonality of synapse loss across these diseases makes it a key therapeutic target, and in addition, most neurological drugs work at the level of synapses, making them a very ‘druggable’ target. Prof Spires-Jones summarised data from her team and others that showed that in MND, synapse degeneration in the frontal cortex is associated with cognitive decline, and damaging TDP-43 protein is found in synapses. Targeting these pathways could be beneficial to prevent or treat MND.

We also heard an interesting talk from Prof Schiavo in session 5A (C29) on the use of axonal transport as a therapeutic target. Deficits in axonal transport are found in many neurological diseases, including MND.  These deficits appear before/at disease onset and are likely to be important in the development of MND. Schiavo talked us through data that showed that the p38 MAPK signalling cascade, which is important for axonal transport, is increased in the SOD1 mouse model of MND, and that long-term treatment with a p38 MAPK inhibitor partially restores physiological function in MND neurones in vitro and in vivo. Another example showed that inhibition of the insulin-like growth factor-1 receptor (IGF1R) (which is overexpressed in MND patients) restores axonal retrograde transport in a SOD1 mouse in vivo, providing further evidence of the possible beneficial effects of targeting key pathways linked to axonal transport. The take-home message was that axonal impairments are reversible and can be modulated by small molecule inhibitors.

Lifestyle & environment: Highlights from Glasgow

This blog is part of the ‘Highlights from Glasgow’ collection of articles, where you can read about the content of some of the talks and posters presented at the 29th International Symposium on ALS/MND.

In the Epidemiology session (5C), several talks focused on the risk associated with various lifetime events, and the demographics of people who develop MND categorised by onset at various body regions. Susan Peters (C37) and her colleagues studied a group of 1,500 people with MND and 3,000 control participants, and found that people who had suffered head trauma after the age of 55 had an increased risk of developing the disease compared to those without this type trauma. They further found reduced risk in people currently/recently taking antihypertensive and cholesterol-lowering medication, but this risk was significantly increased in people who were taking these medications earlier in life. These findings now need to be explored further to investigate the underlying mechanisms that would explain these differences.Read More »

MND and the mind – who is affected?

Motor Neurone Disease (MND), as the name suggests, is known as a disease of motor neurons, a specific type of neurons that co-ordinate our voluntary movement, leading to loss of the ability to move, speak and breathe. And perhaps because the main focus often falls on the rapidly-progressing physical symptoms and their management, the way MND affects the mind has often be overlooked.

brain networkMost literature on MND states that certain behavioural and cognitive (thinking) problems affect up to 50% people with MND, out of which 15% have a co-occurring diagnosis of frontotemporal dementia (FTD). Adding to this, a recent paper by Dr Christopher Crockford and colleagues, published in the journal Neurology, found that up to 80% of people living with MND will have some form of cognitive or behavioural impairment by the final stage of their disease (or in other words, only 20% will have an intact cognitive and behavioural processing).Read More »

MND research around the world

worldmap annotated and marked

In the last decade, the MND Association has invested millions in research within the UK and across the world. We are a leader in the funding and promotion of cutting-edge MND research and, with over 30 years experience of identifying the most promising projects, we only fund and support scientific and medical research of the highest quality and relevance to MND.

And the great news is, we are not the only ones!

alliance_logo_landscape_rightThe International Alliance of ALS/MND Associations has 54 member institutions, in 40 countries around the world – from Mongolia to Mexico, Malta to Malaysia – who are supporting, funding, collaborating in and carrying out MND research, and/or offering much needed care and support to people with MND and their families.

All the institutions listed by the Alliance are shown on the map above. If you want to take a look at some of these, they are easy to access through the International Alliance website. Some of the websites are not in English but you can use the Google Translate Web tool to translate the entire site into English (or any other language).

So let’s take a whistle-stop tour and explore some of the latest research and support projects that other institutions around the world are involved in. The institutions I mention are shown on the map with a yellow pointer.Read More »

Why do we need the MND Register?

Whilst we believe that there are currently around 5,000 adults in the UK living with MND at any one time, the precise figure is not known as there is no single source of information to confirm it. The MND Register of England, Wales and Northern Ireland is set to find a more accurate figure of the true number of people living with the disease. This research study, funded by the MND Association with the support of The Betty Messenger Charitable Foundation and a family trust that wishes to remain anonymous, is jointly led by Professor Ammar Al-Chalabi at King’s College London and Professor Kevin Talbot at the University of Oxford.

Despite our increasing knowledge of the role that genetics plays in MND, there is strong evidence to suggest that MND is a complex disease that is triggered by a combination of genetic predisposition to the disease and exposure to external environmental influences such as occupational and lifestyle factors.Read More »

Steps to understanding MND

Love them or loath them, the band Steps’ first single ‘5,6,7,8’ was a techno line dance song released in 1998 from their debut album ‘step one’, with the B side ‘words of wisdom’.

Using this forced and purely tenuous link and an equally awkward segue, I would like to share with you the news that the journal Neurology this week published further words of wisdom from Professor Adriano Chio, Professor Ammar Al-Chalabi and colleagues, that revisits the multistep hypothesis of MND. Their previous work showed that when no genetic cause is considered, developing MND is a six-step process. In their most recent work, the team investigated how many of the steps does a genetic mutation account for in this multistep process, with a focus on the most common MND causative genes SOD1, TARDBP, and C9ORF72.Read More »

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 »

Does physical activity cause MND? A fresh look at the evidence

Physical activity and MND – part 1

Every month the Research Information team looks at ‘the stats’ for the MND Research blog. These show us how many times each of our blogs are looked at and, every month, ‘Physical activity and MND – is there a link?’ features in the top five. This is possibly driven by media stories of professional sportspeople who have been diagnosed with MND. As we receive a lot of emails about this subject, we felt it was about time for an update as ‘the stats’ suggest this is a topic close to people’s hearts.

This is the first of three blog articles looking at MND and physical activity and other factors that may, or may not, play a role in the development of the disease.
