Sharper in the morning: Cognitive time of day effects revealed with high-frequency smartphone testing Decades of research has established a shift from an “eveningness” preference to a “morningness” preference with increasing age. Accordingly, older adults typically have better cognition in morning hou...

Thanks! And yes you are on to something with testing people under "stress" of different kinds. In another paper by my PhD student Hannah Wilks, we found that testing OAs in the evening revealed about 10% more memory deficits in those with AD pathology. pmc.ncbi.nlm.nih.gov/articles/PMC...

Overall, we think it sends a pretty positive message about the validity of remote, unsupervised #digitalcognition #EMA, in general. But of course we have to collect information about environments and especially distractions.

One surprise was that the number of sessions where participants reported distractions was about 12% of sessions. So distractions are very very common and its really important to allow participants to tell you when they experience them in remote studies. 4/n

However, for those with very mild dementia (consistent with Mild Cognitive Impairment), environments and distractions started to matter more. Taking tests away from home AND when around others impacted those with cognitive symptoms. 3/n

We followed 380 cognitively normal (CN) older adults and 37 with very mild dementia with our smartphone #EMA platform called ARC. For the CNs, it didn't seem to matter if tests were taken at home or around others. Even sessions where overt distractions were experienced didn't matter. 2/n

Top scientists warn that Trump policies are causing a 'climate of fear' in research Some 2,000 scientists, including dozens of Nobel Prize winners, have signed an open letter warning that the U.S. lead in science is being "decimated" by the Trump administration's cuts to research.

Researchers find a hint at how to delay Alzheimer's symptoms. Now they have to prove it An experimental treatment appears to postpone Alzheimer's symptoms in some people genetically destined to get the disease at a young age.

"This treatment has given me an extension to my life that I never banked on having." A groundbreaking Alzheimer’s study led by WashU Medicine researchers shows promise in delaying symptom onset that could change the lives of those genetically at risk. apnews.com/article/alzh...

Had a fantastic time visiting @ctrlab.org in STL, presenting at the Washington University Aging & Development seminar, watching Dr. Hassenstab kick a$$ teaching Psych students, great dinner with Wash U friends and finishing off with a brewery tour! Whirlwind couple of days. Thanks Jason!

Federal judge halts Trump administration cuts to NIH research payments in 22 states Attorneys general sued the Trump administration to block a NIH decision that would slash grant payments for research overhead

The entire landscape of medical research is shifting on an hour to hour basis. The whiplash is stupefying. As of now (Monday evening) the NIH 15% cap on indirects has been halted by a judge in 22 states but who knows what tomorrow brings www.statnews.com/2025/02/10/n...

What The NIH Cut To Indirect Cost Payments Could Cost Red States The Trump administration’s decision to cap how much NIH will pay for indirect costs on university research grants would cost 10 red states more than $1 billion.

Alzheimer’s disease is non-partisan. Cancer is non-partisan. Diabetes is non-partisan. This is a short-sighted policy that could cost thousands of jobs and set biomedical research progress back by years. Contact your local representatives and urge them to stand against this dangerous policy.

The brain’s action-mode is created by a dedicated action-mode network (AMN) rdcu.be/d5odm. In the brain’s mode continuum, AMN sits opposite DMN’s default-mode, as yin-yang. AMN might be key in pain, apathy, Parkinson’s. New @natrevneurosci.bsky.social w/ Marc Raichle & @gordonneuro.bsky.social 🧵 ⬇️

Incredible thread detailing a biochemist's experience as an expert witness. The supplement Prevagen is advertised widely and patients concerned about their memory often ask us if it is effective. TLDR: Most of the effective ingredient can't withstand more than 30 seconds in the stomach. #ENDALZ
