As research expands beyond amyloid and tau, experts discuss how novel biomarkers could identify multiple coexisting neurodegenerative pathologies and pave the way for more personalized treatment approaches based on each patient’s unique disease profile. [WATCH TIME: 9 Minutes]

As research moves toward treating Alzheimer disease before symptoms emerge, experts highlight the potential of plasma biomarkers to identify at-risk individuals, guide clinical trial enrollment, and create a window for intervention before irreversible neuronal damage occurs. [WATCH TIME: 6 Mintes]

Experts discuss how plasma biomarkers may enable earlier detection of Alzheimer disease pathology, including in cognitively unimpaired individuals and those with subjective cognitive decline, while offering a more accessible alternative to CSF and PET-based assessment. [WATCH TIME: 8 Minutes]

Phase 1b data published in Nature Medicine and presented at AAIC 2026 showed target engagement and reductions in select cerebrospinal fluid biomarkers of neuronal and synaptic injury with the investigational anti-PD-L1 antibody.

Extended follow-up and new AAIC 2026 data show that tazbentetol, a first-in-class oral synaptic regenerative therapy, produced rapid and durable improvement in cognition and EEG biomarkers in patients with mild-to-moderate Alzheimer disease.

The Trojanowski Professor for Neurodegenerative Disease Research at the University of Pennsylvania, discusses how postmortem and longitudinal imaging findings provide new insights into the potential downstream effects of amyloid clearance on tau pathology and neurodegeneration in Alzheimer disease.

A 12-week, placebo-controlled phase 2 trial found that an oral THC/CBD combination significantly reduced agitation in hospice-eligible patients with Alzheimer disease and other dementias, meeting its primary and key secondary endpoints.

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]

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 APPLAUDS trial will evaluate mivelsiran, an intrathecally delivered siRNA targeting amyloid precursor protein, in cognitively stable adults aged 40 to 55 with early-stage Down syndrome and early-stage Alzheimer disease who have elevated amyloid burden.
