A new online activity has been launched to help explain the relationship between multiple sclerosis (MS) and coronavirus to children.
The activity, designed by Digesting Science and aimed at families with six- to 12-year-olds, takes around 20 to 30 minutes, and covers the immune system and how white blood cells fight infections like coronavirus and whether treating MS makes you more vulnerable to coronavirus.
Those wanting to try the activity will need some props, including pasta, paper or card, scissors, drinking glasses, a bowl, a blindfold, a pen and some tape.
Digesting Science recently hosted a series of online events for young people with MS covering the disease and issues around Covid-19, emotion, diet and lifestyle, and cognitive changes in school.
Eight families from Evelina London Children’s Hospital and Great Ormond Street Hospital involving young people between the ages of 13 to 18. After completing the activity, families were asked how confident they felt discussing MS and Covid-19 before and after completing the activity.
Before the activity most participants reported that they were “somewhat” confident about talking about MS and covid-19, and after the activity, they were generally “confident” or “very confident” about doing so.
Alison Thomson, lecturer in Public Engagement and Public Engagement in Science at Queen Mary University of London, works with the MS research team and the Royal London hospitals they have clinical services.
She has been working on Digesting Science for the last decade, aiming to help improve public engagement and bridge the gap between researchers and patients and their families to educate on MS.
“I don’t have scientific background, so when I first met the researchers, I had no idea what MS was,” she tells NR Times.
“I gave them plasticine and objects and asked them to make models of their research, and from that one activity we were able to develop educational talks about how to communicate MS in simple forms, using plain English and objects to demonstrate meaning.”
Before the virus, the events took place in person, in spaces including charities, therapy centres and science events across the country. But when the pandemic came, they knew they would have to adapt.
“When the pandemic started, from a neurology service side of things, MS patients wanted to know what was going on, whether they were at risk, should they be shielding,” Thomson says.
“As our scientists began learning more about Covid 19 and how it interacted with the immune system and different therapies MS patients are on, they talked to me about how to communicate that quickly to audiences.
“We put together this activity, which is bridging the gap between the basics we already know and this is new information about Covid-19. We also spoke to families about the questions they were getting asked by their children.”
Thomson and her researchers worked with families to make sure they understood what the online activity was communicating, and scientists to ensure everything was factually correct, before introducing it to families through Evelina London Children’s Hospital and Great Ormond Street Hospital.
Thomson says that, while the activities are aimed at children, they also help adults to better understand MS.
“A lot of adult participants learn a lot through it, as well. The minute you’re diagnosed with MS, there’s a lot of jargon. It can get very confusing very quickly.
“We generally don’t update our scientific knowledge beyond school until someone is diagnosed with something, so if we’re not used to learning about science or using those processes of academic publishing, then it can be very scary.”
“Some people do become very engaged in learning about science so they can have those conversations and ask questions,” Thomson says.
MS research reveals sight breakthrough
Vision in patients with multiple sclerosis (MS) could be improved through the use of medication, a new study has found.
A mice study investigated the effect of indazole chloride (IndCl) on the pathology and function of the afferent visual pathway for the first time, which includes the eyes, optic nerve, and all brain structures responsible for receiving, transmitting, and processing visual information.
“IndCl has been previously shown in mice to reduce motor disability, increase myelination, and neuroprotection in the spinal cord and corpus callosum,” says Seema Tiwari-Woodruff, a professor of biomedical sciences at the UC Riverside School of Medicine and the study’s lead author.
“Its effects in the visual system, however, were not evaluated until now.
“Our study shows the optic nerve and optic tract, which undergo significant inflammation, demyelination, and axonal damage, are able to restore some function with IndCl treatment with successful attenuation in inflammation and an increase in remyelination.”
In MS, damage can often be caused to the optic nerve and other parts of the visual system, which results in around 50 per cent of patients with MS experiences optic neuritis – inflammatory demyelination of the optic nerve – prior to showing initial symptoms.
Almost all MS patients have impaired vision at some point during disease progression. Symptoms can include eye pain, blurred vision, and progressive vision loss that can lead to blindness, among other visual impairments.
The researchers used IndCl to assess the impact on demyelinating visual pathway axons. The treatment induced remyelination and mitigated some damage to the axons that resulted in partial functional improvement in vision.
The visual pathway in mice is similar to that in humans, say researchers. In the lab, Professor Tiwari-Woodruff and her research group first induced the mouse model of MS. They let the disease progress for about 60 days, and when the disease reached a peak between 15 and 21 days, they administered IndCl to half the mice.
At the end of the experiment, they performed functional assay to measure the visual electrical signal, and immunohistochemistry to examine the visual pathway.
The mice that received the drug showed improvement in myelination, with visual function improving by about 50%.
“Measuring visual function and recovery in the presence of novel therapies can be used to screen more effective therapies that will protect axons, stimulate axon remyelination, and prevent ongoing axon damage,” says Professor Tiwari-Woodruff.
Currently approved MS drugs reduce inflammation but do not prevent neurodegeneration or initiate remyelination. Further, they only partially prevent the onset of permanent disability in patients with MS.
“We treated the MS mice with IndCl at peak disease,” Professor Tiwari-Woodruff says.
“If the brain is highly diseased, some of the axons that could potentially restore visual function are too damaged and will not recover. There’s a point of no return.
“Our paper stresses that to acquire vision improvement, treatment must start early. Early treatment can recover 75%-80% of the original function.”
Tiwari-Woodruff stresses that although additional studies are required, the new findings show the dynamics of visual pathway dysfunction and disability in MS mice, along with the importance of early treatment to mitigate axon damage.
“There is a strong and urgent need to find a therapeutic candidate that restores neurological function in patients with MS,” Professor Tiwari-Woodruff adds.
“Therapeutics must target remyelination and prevent further axonal degeneration and neuronal loss. The good oestrogens, which have neuroprotective and immunomodulatory benefits, could be candidates for MS treatment.”
New research assesses impact of medication on MS symptom
The effect of medication Tysabri on cognitive fatigue in people with multiple sclerosis (MS) is to be analysed in a new research study.
The study will look at how the medication, also known as natalizumab, impacts cognitive fatigue in individuals with relapsing and remitting MS.
Most people living with MS report symptoms of cognitive fatigue, which can adversely affect their ability to perform activities in their everyday lives.
Statistics show that over 40 per cent consider such fatigue their most troubling symptom.
However, despite its impact, there are few treatment options, with none of the widely-used interventions used to slow progression of physical symptoms proven to treat cognitive fatigue.
In this study, led by the Kessler Foundation, the potential efficacy of Tysabri in alleviating cognitive fatigue among those with MS will be explored, in what could have transformational effects for people with the condition.
“Using this rigorous study design, we will add to our understanding of the neural mechanisms associated with Tysabri therapy,” says Dr John DeLuca, who is leading the study.
“We expect to draw firm conclusions about the effect of Tysabri on cognitive fatigue, which may be an important step toward expanding the options for treating this disabling symptom.”
The latest neuroimaging techniques are being used in the project, resulting in the identification and validation of a physiological biomarker, which will be used in determining the outcomes of this study.
The biomarker defines the brain activity patterns associated with cognitive fatigue, according to Dr DeLuca, senior vice president of Research and Training at Kessler Foundation.
“The biomarker enables us to objectively study disease-modifying therapies for MS such as Tysabri for their effects on cognitive fatigue,” he says.
The study will compare ten healthy controls with 15 individuals with MS who are planning to start Tysabri treatment.
During the initial six months of treatment, researchers will use functional MRI to measure the brain activation associated with cognitive fatigue induced by performing a cognitively challenging task.
They will also look at changes in the timing of the onset of cognitive fatigue as treatment progresses through the study, which is titled ‘Biomarker for Cognitive Fatigue using Functional Imaging in Multiple Sclerosis’.
It marks the latest major study from Kessler Foundation, a global leader in rehabilitation research that seeks to improve cognition, mobility and long-term outcomes, including employment, for people with neurological disabilities caused by diseases and injuries of the brain and spinal cord.
Groundbreaking research into MS could enable development of new treatments
The types of nerve cells which are lost through developing Multiple Sclerosis (MS) have been identified for the first time, in a breakthrough which could yield the development of new nerve-protecting treatments.
In a new study, researchers found that the inhibitory interneurons are lost in people who have MS.
Previously, it was only known that myelin, the protective coating around nerves, is damaged in MS – but pinpointing the selective loss of specific nerve cells has now been established.
The research, from the MS Society Edinburgh Centre for MS Research, could now lead to steps forward in the development of treatments to help protect the nerves most at risk.
Using brain tissue samples from the MS Society Tissue Bank, Professor Anna Williams and her team found a dramatic reduction in the number of inhibitory interneurons in tissue from people who had been living with MS, compared to people without the condition.
Another type of neuron – stimulating neurons – remained the same, even in people who had MS for decades.
Current treatments for MS target the immune system and reduce damage to the myelin, but by identifying how to replace lost myelin and protect nerves is the goal for researchers – and has been brought closer by this research.
“Our research has shown that a specific type of neuron, called an inhibitory interneuron, is damaged in people with MS,” says Professor Williams, who led the study.
“This is really important because, in the search for new treatments, it focuses our efforts on trying to stop the damage and death of these special cells.
“Our next step is to convert this knowledge into new treatments that protect nerves and prevent neurodegeneration – and ultimately disability – in people living with MS.”
The research team also generated a new mouse model of myelin damage, which showed the same selective loss of inhibitory neurons seen in humans – showing that myelin damage leads directly to nerve damage.
Researchers will now be able to test new treatments in the mice to see if they can prevent the inhibitory neurons from being damaged. This will help develop new treatments to protect nerves in MS.
Dr Lida Zoupi, who worked on this study, says: “In our mouse model, we show that demyelination directly leads to neurodegeneration, answering a long-standing debate between MS researchers in the process.
“By confirming this, we have a vital new insight into the mechanisms behind neurodegeneration, which could potentially be used as a model for the development of neuroprotective treatments.”
The research was hailed as a vital step in the ongoing efforts to understand MS and develop treatments as a result.
“We’ve made huge progress in finding treatments that target the immune system, but many people living with MS still don’t have access to effective treatments,” says Dr Emma Gray, assistant director of research at the MS Society.
“We believe this study represents a vital step in our mission to stop MS.
“Work like this, which is based at our Edinburgh Centre and used samples from the MS Society Tissue Bank, shows just how important charity funded research is to the overall research landscape, and we’re proud to have made it possible.”
