MINNEAPOLIS – For people with multiple sclerosis (MS), having a COVID-19 infection is not associated with worsening MS symptoms or disability, according to a study published in the December 23, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology.
“Infections may be associated with more disability among people with MS,” said study author Amber Salter, PhD, of UT Southwestern Medical Center in Dallas, Texas, and a member of the American Academy of Neurology. “However, our study found that for COVID-19 infections specifically, this was not true. This is good news for people with MS, that they do not need to worry about long-term worsening of their MS symptoms after a COVID-19 infection.”
The study involved 2,132 adults with MS with an average age of 65. They were followed over 18 months.
Participants completed a questionnaire, reporting whether they ever had a COVID-19 infection that was confirmed by a test.
A total of 796 people reported having a COVID-19 infection and 1,336 people reported never having COVID-19.
Participants also reported the severity of their MS symptoms at least six times during the study. They were asked about walking, hand function, bodily pain, fatigue and memory and thinking. They were scored based on symptom severity.
Participants also reported their level of disability based on how their condition affects daily activities like walking or standing.
After adjusting for factors such as age, race and gender, researchers found that for both those with COVID-19 infection and those without, MS symptom severity increased nominally by 0.02 points per month, both before and after a COVID-19 infection. They found no difference in MS symptom severity between those with COVID-19 infection and those without.
For disability, researchers found similar results.
“Our study indicates that COVID-19 infection was not associated with immediate changes in symptom severity or disability, nor did it change the MS symptoms or disability trajectory for more than a year and a half after the infection,” said Salter. “While our study looked primarily at older people and results may not be the same for younger people, these findings help us better understand how this type of infection can affect people with MS.”
A limitation of the study was that tests for COVID-19 infection can produce incorrect results, so not everyone who had COVID-19 may have tested positive. Also, people may have had COVID-19 and did not know it.
The study was supported by the National Multiple Sclerosis Society.

Human-related activities continue to threaten global climate and productivity
2024-12-23
The pace at which anthropogenic climate change has altered the terrestrial carbon stores is making our current climate-change mitigation efforts seem fruitless, unless behaviors are quickly changed.
Climate change induced by human behaviors, or anthropogenic climate change, has been a hot topic for decades and is not going away. As with any problem, reviewing datasets from the past to analyze trends and garner information is one of the first steps towards a solution. Gross primary productivity, or GPP, is a key indicator of the overall health of an ecosystem and is the amount of CO2 fixed by plants per unit of time and area. Researchers ...
Public shows greater acceptance of RSV vaccine as vaccine hesitancy appears to have plateaued
2024-12-23
PHILADELPHIA – A year after becoming available, vaccines to protect against RSV in newborns and older adults are being more widely accepted by the American public, according to a new Annenberg Public Policy Center (APPC) health survey conducted in November 2024.
Over half of U.S. adults (52%) think the vaccine given to pregnant individuals to protect their infants from RSV (respiratory syncytial virus) is effective, up from 42% in October 2023, soon after the Centers for Disease Control and Prevention (CDC) recommended the vaccine. And 61% say the RSV vaccine for adults age 60 and older is effective, up from 54% ...
Unraveling the power and influence of language
2024-12-23
A choice was made to include each word in this sentence. Every message, even the most mundane, is crafted with a specific frame in mind that impacts how the message is perceived.
The study of framing effects is a multidisciplinary line of research that investigates when, how, and why language influences those who receive a message and how it impacts their response.
This multifaceted science is in the spotlight in the latest issue of Psychological Science in the Public Interest. Stephen Flusberg of Vassar College and his team provide a comprehensive review of ...
Gene editing tool reduces Alzheimer’s plaque precursor in mice
2024-12-23
CHAMPAIGN, Ill. — A new gene editing tool that helps cellular machinery skip parts of genes responsible for diseases has been applied to reduce the formation of amyloid-beta plaque precursors in a mouse model of Alzheimer’s disease, researchers at the University of Illinois Urbana-Champaign report.
The application in live mice shows the improved efficiency of the tool, called SPLICER, over the current standard in gene editing technology, as well as the potential for application in other diseases, the researchers said. Led by Pablo Perez-Pinera, a professor of bioengineering at ...
TNF inhibitors prevent complications in kids with Crohn's disease, recommended as first-line therapies
2024-12-23
Early treatment of pediatric Crohn’s disease with anti-tumor necrosis factor medications can substantially reduce the risk of perianal fistulas, a particularly debilitating complication of Crohn’s disease.
Michigan Medicine researchers confirmed this finding using prospective data.
The resulting paper, “Early tumour necrosis factor antagonist treatment prevents perianal fistula development in children with Crohn’s disease: Post-hoc analysis of the RISK study,” appeared in Gut.
A previous retrospective study from the same team had established a link between early treatment and reduced likelihood of perianal fistulas.
That research, however, ...
Twisted Edison: Bright, elliptically polarized incandescent light
2024-12-23
ANN ARBOR—Bright, twisted light can be produced with technology similar to an Edison light bulb, researchers at the University of Michigan have shown. The finding adds nuance to fundamental physics while offering a new avenue for robotic vision systems and other applications for light that traces out a helix in space.
"It's hard to generate enough brightness when producing twisted light with traditional ways like electron or photon luminescence," said Jun Lu, an adjunct research investigator in chemical engineering at U-M and first author of the study on the cover of this week's Science.
"We ...
Structural cell protein also directly regulates gene transcription
2024-12-23
ITHACA, N.Y. -- A cell protein previously believed only to provide a scaffolding for DNA has also been shown to directly influence DNA transcription into RNA – the first step of the process by which an organism’s genetic code expresses itself. The fundamental breakthrough was discovered in apple cells but is relevant to all living organisms made of nucleus-containing cells, including humans.
The finding, published Dec. 20 in Plant Cell, was co-authored by Cornell researchers and colleagues from the University of California, Davis, and Shandong Agricultural University in Shandong, China.

Breaking boundaries: Researchers isolate quantum coherence in classical light systems
2024-12-23
Understanding the boundary between classical and quantum physics has long been a central question in science. While thermal light fields have traditionally been viewed as classical, the team fragmented these fields into smaller multiphoton subsystems. Surprisingly, they uncovered quantum coherence—features such as particle interference previously thought unique to quantum systems—within a classical light source.
By using a sophisticated technique involving photon-number-resolving detection and orbital angular momentum (OAM) measurements, the researchers projected a classical pseudothermal light field into isolated multiphoton ...
Brain map clarifies neuronal connectivity behind motor function
2024-12-23
(MEMPHIS, Tenn. – December 23, 2024) Signals relayed to motor neurons from the brain enable muscle movement, but these signals typically pass through spinal interneurons before they reach their destination. How the brain and this highly diverse group of “switchboard operator” cells are connected is poorly understood. To address this, scientists at St. Jude Children’s Research Hospital created a whole-brain atlas visualizing regions of the brain that send direct inputs to V1 interneurons, a group of cells necessary for movement. The resulting atlas and accompanying three-dimensional interactive website provide a framework to further understand ...
