Dementia and Alzheimer Disease

Take 5 minutes to catch up on NeurologyLive®'s highlights from the week ending July 24, 2026.

Yogesh Shah, MD, explains the biological basis of P-tau217 and why blood-based biomarker testing is emerging as a practical, highly accurate tool for identifying Alzheimer's pathology.

Stephen Williams, PhD, chief scientific officer of Alamar Biosciences, discusses the potential of eMTBR-tau measurement, multiplex biomarker testing, and AI-driven approaches to improve the characterization of Alzheimer disease and its coexisting pathologies.

Kristen Harris, MD, Medical Director of the Extended Recovery Unit at Hackensack Meridian JFK Johnson Rehabilitation Institute, discussed new findings on functional recovery and community discharge rates in acquired brain injury patients undergoing skilled nursing facility rehabilitation.

At AAIC 2026, the head of sciences at the Alzheimer Center Amsterdam, discusses the growing role of biomarkers in understanding the biological complexity of Alzheimer disease and advancing more personalized approaches to diagnosis and treatment. [WATCH TIME: 3 minutes]

Ahead of World Brain Day, NeurologyLive explores 5 emerging strategies for preventing neurologic disease, from modifiable dementia risk factors to GLP-1 drugs, sleep science, the gut brain axis, and wearable technology.

From concussion recognition to blood-based biomarkers and the long-term effects of repetitive heading, neurologists discuss how emerging research is changing the understanding of brain injury in the world's most popular sport.

Laura Nisenbaum, PhD, Interim Chief Science Officer at the Alzheimer's Drug Discovery Foundation, shares her perspective on the FDA's approval of a subcutaneous starting dose for lecanemab and what it means for access, clinical practice, and the future of Alzheimer disease treatment.

Understanding how amyloid pathology develops years before symptoms emerge is essential to appreciating the growing role of blood-based biomarkers in earlier Alzheimer disease detection.

The $100 million PROTECT-Cog trial will test whether adding a GLP-1 drug to the proven U.S. POINTER lifestyle intervention further cuts dementia risk in at-risk older adults.

PrevenTRON, a study of trontinemab, will enroll 1600 cognitively unimpaired participants identified by elevated plasma p-tau217, using time to clinical progression as the primary endpoint.

SAR448851 showed favorable safety, high CNS penetration, and up to 50% reductions in CSF soluble TREM2 in phase 1, supporting the design of TREMHANCE, a phase 2 trial now in final planning with p-tau217 as its primary endpoint.

The global phase 3 registration trial enrolled 1535 patients across 240 sites and has completed its 52-week double-blind treatment phase, with no unexpected safety signals observed, even in participants on concomitant antiamyloid therapies.

Across 3 first-in-human studies in healthy volunteers and cognitively impaired adults, MK-2214 demonstrated dose-proportional pharmacokinetics, an approximately 80-day half-life, and near-complete suppression of free pS413 tau in CSF at doses of 20 mg and above.

The assistant professor in the Department of Behavioral Science at the University of Kentucky discusses a nonpharmacologic intervention designed to address sensory processing impairments in older adults with dementia. [WATCH TIME: 5 minutes]

At AAIC 2026, the senior research professor of neurology at Indiana University School of Medicine discussed the evolving role of blood-based Alzheimer disease biomarkers, particularly p-tau217.

At AAIC 2026, professor of neurology at Washington University in St. Louis discussed how integrating clinical assessment with amyloid biomarkers can improve diagnostic accuracy in Alzheimer disease. [WATCH TIME: 5 minutes]

The 60 mg dose showed the largest treatment effect, slowing decline by 26% on CDR-SB, 42% on ADAS-Cog13, and 50% on MMSE at 18 months, while all doses produced 50% to 65% reductions in CSF total tau and unprecedented tau PET reductions across brain regions.

At AAIC 2026, associate professor of neurology at Albert Einstein College of Medicine discussed a culinary medicine intervention to improve MIND diet adherence and mood in older adults with type 2 diabetes. [WATCH TIME: 5 minutes]

MCLENA-1 enrolled only 6 completers due to funding constraints but demonstrated 12 months of continuous lenalidomide was safe and tolerable, with nonsignificant trends favoring treatment on cognition and global outcomes.

A new phase 2 trial, presented at AAIC 2026, aims to evaluate the effects of urolithin A on mitophagy/autophagy activity, oxidative stress, multi-omic profiling, and cognitive function in APOE4 carriers.

The approval allows patients to begin lecanemab treatment at home via weekly subcutaneous injection, eliminating the 18-month IV requirement that previously preceded any at-home dosing.
