Dementia and Alzheimer Disease

Here's some of what is coming soon to NeurologyLive® this week.

Using plasma p-tau217 shows promise as an effective, less invasive pre-screening method for identifying amyloid-β positive individuals in Alzheimer disease clinical trials.

In addition to showing a slowed disease progression, TPN-101-treated patients had lowered levels of key biomarkers involving neurodegeneration and neuroinflammation.

Take 5 minutes to catch up on NeurologyLive®'s highlights from the week ending August 2, 2024.

The 3-year data highlighted the safety profile of lecanemab and its disease-modifying effects on tau accumulation and other biomarkers related to AD pathology.

The use of a blood test significantly improved diagnostic accuracy compared with standard clinical evaluations for Alzheimer disease, especially in primary and secondary care settings.

Although the primary endpoint of cerebral glucose metabolic rate change was not met, secondary endpoints showed significant benefits in brain volume and cognitive measures, further supporting the potential of GLP-1 agonists in AD.

CT1812, a sigma-2 receptor ligand, showed favorable changes in biomarkers like Aß40, Aß42, and neurofilament light (NfL), indicating its potential as a synaptoprotective agent.

Higher MIND diet scores correlate with larger hippocampal volume in older adults, suggesting potential benefits for brain health.

A study recently presented at AAIC 2024 showed that higher consumption of processed red meat significantly increased the risk of dementia and cognitive decline among adults in the United States.

The director of the Brain Health Observatory at the University of Southern California discussed the potential impact of Alzheimer disease blood tests on reducing clinic wait times and improving the diagnostic process in primary care.

The co-founder and chief science officer at Longeveron provided commentary on the therapeutic potential of Lomecel-B, a living cell product in development for patients with Alzheimer disease. [WATCH TIME: 3 minutes]

A small clinical trial showed RG6289 dose-dependently altered amyloid-ß monomers in CSF, supporting its development for Alzheimer's disease.

The professor of neuroscience at Imperial College London talked about results from a study assessing a glucagon-like peptide-1 analogue, liraglutide, in patients with Alzheimer disease. [WATCH TIME: 5 minutes]

In Latino individuals, larger household size negatively affects MoCA scores, while higher education positively impacts cognitive outcomes, per SERVE OC trial data.

Over a 6-month treatment period, changes in apathy for methylphenidate-treated patients were not associated with performance on the remaining cognitive tests.

The chief medical officer at Eisai provided context towards the ongoing initiatives to further the efficacy and safety profile of lecanemab, an FDA-approved treatment for early Alzheimer disease. [WATCH TIME: 3 minutes]

The trial will use phase 2a to determine the optimal dosage while phase 2b will assess efficacy and long-term safety of the optimized dose against a placebo arm.

The drug showed a strong safety profile and met primary endpoints, showing efficacy in slowing clinical and biological decline and supporting further investigation in a phase 2/3 trial.

Marketed as Zunveyl for mild-to-moderate Alzheimer disease, ALPHA-1062 is considered a new-generation acetylcholinesterase inhibitor with expected minimal gastrointestinal adverse events.

A duo of experts talked about the association of long-term exposure to fine particulate matter from wildfires and the increased risk of dementia among older adults. [WATCH TIME: 7 minutes]

Here's some of what is coming soon to NeurologyLive® this week.

The vaccine induced a specific humoral immune response, positively affecting several AD-related biomarkers, and showed potential as a treatment for AD, with further trials planned.

The director of the Brain Health Observatory at the University of Southern California talked about integrating blood tests into primary care to better triage patients with Alzheimer disease, reduce unnecessary referrals, and shorten appointment wait times. [WATCH TIME: 7 minutes]
