Loss of gray matter in the spinal cord clearly associates with greater disability in people with multiple sclerosis (MS), but determining the extent of its loss is limited by an inability to accurately measure gray matter in all patients, a small study in Spain reported. The true amount of…

Having at least one pregnancy may lower disability scores in women with multiple sclerosis (MS), but breastfeeding for longer than six months may worsen damage to the brain, an observational study in patients has found. Findings support the need for careful pregnancy planning, counseling, and treatment management to ensure…

Changes in the amount of grey matter in specific regions of the brain appear to occur early in relapsing multiple sclerosis (MS), while structural changes in white matter happen late in disease progression. These were among the findings of a recent study that tracked the sequence of events in…

In people with multiple sclerosis (MS) under age 50, the presence of cardiovascular risk factors is associated with a greater loss of brain volume, including white and grey matter, a study showed. The brain’s white matter mainly consists of nerve fibers and is typically affected by MS, while…

A high-dose chemotherapy combination given to wipe out the immune system before its rescue with autologous hematopoietic stem cell transplant (aHSCT) can cause “transient” damage to neurons and supporting cells of the central nervous system in people with aggressive multiple sclerosis (MS), a Canadian study reports. Nonetheless, its researchers believe…

A new radiotracer called [F-18]PBR06, used in positron emission tomography (PET) imaging, helps detect changes in the brain’s grey matter that are linked to progressive forms of multiple sclerosis (MS), a study shows. The findings support [F-18]PBR06’s potential for detecting signs of disease progression even before patients show…

A method based on cerebrospinal fluid measurements and magnetic resonance imaging (MRI) can aid in stratifying patients with multiple sclerosis (MS) at the time of diagnosis, which may help identify a tailored therapeutic approach for each patient from early disease stages. The data was presented by Roberta Magliozzi, from…

Diabetes, hypertension, and active smoking correlate with more brain shrinkage in multiple sclerosis (MS) patients, a new study shows. The study, “Assessing the burden of vascular risk factors on brain atrophy in multiple sclerosis: A case- control MRI study” was published in the journal Multiple Sclerosis and Related Disorders.

Being overweight is associated with accelerated grey matter volume loss in the brain, a mark of neurodegeneration, in multiple sclerosis (MS) patients, a five-year observational study shows. But vitamin D levels, often suggested as an MS risk factor, do not seem to affect brain volume over time.

In a new study entitled “Reduced cortical microvascular oxygenation in multiple sclerosis: a blinded, case-controlled study using a novel quantitative near-infrared spectroscopy method,” a team of researchers at the Hotchkiss Brain Institute, Cumming School of Medicine, University of Calgary investigated whether frequency domain near-infrared spectroscopy technology can measure the potential…
