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 »
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.
Most 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 »
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!
The International Alliance of ALS/MND Associationshas 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 »
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 »
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 »
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 »
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.
‘Big data’ projects require detailed analysis of unimaginably large volumes of complex data. This is especially true in the realm of MND gene discovery when searching for MND-associated genes – where the greater the number of samples analysed, the greater the possibility of finding the relatively less frequently occurring genetic causes (known as ‘rare’ variants). Literally a needle in a haystack.
These discoveries are no less important, as each new discovery is highly significant and provides another piece of the puzzle in our understanding of the causes and avenues to target for potential treatments. A clear example of this is collecting and mining the data from tens of thousands of human ‘genomes’ to identify the genes responsible for MND. By working together, researchers can greatly increase their ability to tease out the difficult to find discoveries.Read More »
Physical activity has always been at the forefront of factors associated with MND, but studies investigating its effect have often been conflicting. The reason why we might see contrasting results is often due to different cohorts and numbers of people included in the study, the method by which the data was collected, or the types of questions asked and the way they were presented. Increased number of studies on the same topic might then improve the way these are conducted in the future and provide more reliable conclusions.
The most recent multi-centre study that included over 1,500 people with MND and nearly 3,000 control participants was conducted by the Euro-MOTOR consortium under the leadership of Prof Leonard van den Berg. Today (24 April), the group published a paper on their findings in the Journal of Neurology, Neurosurgery and Psychiatry . The study collected data using thorough questionnaires, presented to Dutch, Irish and Italian participants either face-to-face or on paper, asking about their exposure to smoking, alcohol, and the type and amount of physical activity throughout their lifetime – both occupational and leisure. A score was then assigned to each person based on the amount of energy expenditure each activity requires – this is called metabolic equivalent of task (MET).Read More »
In recent news, a number of press releases highlighted a paper published in the journal Cell, in which scientists, under the leadership of the University of Toronto’s Professor Peter St George-Hyslop, and in collaboration with University of Cambridge, described the process of how the FUS protein leads to the development of motor neurone disease (MND) and frontotemporal dementia (FTD).
MND and FTD – what is the connection?
We know that there is a link between MND and FTD, which in most part is caused by a mutation in the C9ORF72 gene, causing familial MND in around 35% cases and FTD in 25% of cases. Mistakes in the gene disrupt normal processes leading to toxic accumulation of TDP-43 protein in the neurons, and their subsequent death. There is however another protein toxic to neurons which results in the development of MND and FTD – the one that makes it slightly easier for us science writers to come up with witty titles: FUS (see one of our previous articles ‘What’s the FUS all about’).Read More »
