New study ties high CTE risk to former NFL players, urges safer head-impact limits

A British Medical Journal study of 878 former NFL players who died from 2016–2021 found 215 of 235 brain donors had chronic traumatic encephalopathy (CTE). The researchers estimate CTE prevalence among all decedents ranged from 24.5% (minimum) to 97.7% (maximum), underscoring a higher risk of neurodegenerative disease and dementia in this population and urging the NFL to reduce repetitive head impacts across levels of play.

GLP-1 Weight-Loss Drugs May Accelerate ALS Progress, Experts Warn

Some doctors warn that GLP-1 receptor agonists used for diabetes and obesity (e.g., semaglutide in Ozempic/Wegovy) could hasten ALS progression by triggering rapid weight loss; a 2025 ALS case study reported a 10-fold acceleration in decline after starting semaglutide, with stabilization after stopping, and ALS care guidelines emphasize maintaining or increasing weight; Novo Nordisk says ALS isn’t listed as a warning in their drug information.

Quadruple Risk: Study Links NFL Careers to Higher Neurodegenerative Deaths

A Mass General Brigham–Boston University–CTE Foundation study of nearly 20,000 NFL players finds death from neurodegenerative disease is about four times higher than in the general population, with dementia and Parkinson’s deaths 3–4x more common; longer careers (five-plus seasons) nearly double the risk versus shorter careers. CTE is considered the primary explanation, though players generally live longer overall due to other protective factors.

Hidden Brain Drain Path Discovered Along the Dura Near a Key Artery

Hidden Brain Drain Path Discovered Along the Dura Near a Key Artery

Researchers identified a slow, lymphatic-like drainage channel in the dura surrounding the middle meningeal artery in healthy adults, using dynamic MRI and postmortem tissue with lymphatic markers PROX1, PDPN, LYVE1. This pathway could help clear cerebrospinal and interstitial fluids, reshaping how we understand brain waste clearance and potentially impacting aging and diseases like Alzheimer’s, while reinforcing the dura as an active immune interface rather than a static barrier.

Psychiatric Medications Associated with Increased ALS Risk and Progression

Psychiatric Medications Associated with Increased ALS Risk and Progression

A Swedish study found that the use of psychiatric medications such as anxiolytics, hypnotics, sedatives, and antidepressants is associated with an increased risk of developing ALS and worse outcomes after diagnosis, including shorter survival and faster functional decline, suggesting a potential link between psychiatric symptoms, medications, and ALS progression.

QurAlis Begins Phase 1 Trial of QRL-101 for ALS Treatment

Quralis has initiated a Phase 1 clinical trial for QRL-101, a novel treatment aimed at reducing nerve cell overactivation in amyotrophic lateral sclerosis (ALS) patients, potentially slowing disease progression. The trial, conducted in the Netherlands, will assess the safety, tolerability, and pharmacological properties of QRL-101. This first-in-class therapy targets Kv7.2/7.3 ion channels to control motor neuron hyperexcitability, a key factor in ALS progression. Results from this study, along with parallel research, will guide future development of QRL-101.
