The professor of psychiatry and cell biology at NYU Langone pleaded his case for why the Alzheimer community should begin to turn to other drug development strategies, including the relatively young phenomenon of autophagy. [WATCH TIME: 3 minutes]

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

The chief medical officer and cofounder of Linus Health provided insight on the outlook of acoustic measures and machine learning to further classify cognitive impairment. [WATCH TIME: 4 minutes]

The FDA expressed concerns about the limitations of the data included in the submission, and recommended that Acadia conduct an additional trial in AD psychosis with pimavanserin (Nuplazid).

Inflammatory coagulation pathway activator positive extracellular vesicles were significantly increased in women with a history of severe preeclampsia compared with controls and those with milder cases.

The neurologist at Cleveland Clinic’s Lou Ruvo Center for Brain Health detailed new findings on whether initial cognitive symptoms have similar rates of functional decline across a handful of neurodegenerative disorders. [WATCH TIME: 3 minutes]

In addition to significant associations between executive memory and cognition, baseline neurofilament light levels and age trended toward significance.

The chief medical officer and cofounder of Linus Health provided background on the reasoning for the measures used in a new machine learning algorithm that classifies cognitive status. [WATCH TIME: 3 minutes]

During a Focused Topic Session at the 2022 Alzheimer’s Association International Conference, NeurologyLive® inquired with a panel of experts about the possibility of exploring a combination approach to Alzheimer disease as the future of treatment.

All severities of Alzheimer disease showed statistically significant benefits from the exercise program relative to controls, with more mild groups demonstrating the most improvement.

The assistant director of computational biology at Stanford University discussed the knowns and unknowns of 2 rare missense variants and their associations with decreased Alzheimer disease risk. [WATCH TIME: 4 minutes]

The professor of psychiatry and cell biology at NYU Langone provided insight on new findings that uncover the sources of neuronal damage in Alzheimer disease that may explain the failures of antiamyloid therapies.

The monoclonal antibody that preferentially targets Aß oligomers failed to meet either of its coprimary end points—despite favorable results over the placebo group—in individuals who were unimpaired but at risk for AD.

Using several large-scale cohorts, findings showed that cumulative incidence of Alzheimer disease grows faster with age in R145C variant carriers compared with noncarriers, contradicting prior research results.
