A photo recap of our successful Yale Cognition Workshop, May 11-12; Look forward to our 2nd workshop in 2027🥂

Such a pleasure to work w fantastic colleagues to make it happen. Coincidentally, the same day in 2018 I was hosting CHPAMS meetings in New Haven w 300+ participants.🌍

Hard to believe the Yale Conference on AI in the Social Sciences is happening next week.

We’ve put together an exciting program featuring leading scholars on how AI is transforming measurement, causal inference, publishing, and the future of social science research.

Only a couple of spots remain due to space constraints.

Looking forward to welcoming everyone to Yale!

🌟New Publication🌟 Examining hearing-impaired older adults in 33 nations, effective hearing aid use is linked to reduced #dementia risk. The association is stronger in middle-income nations, suggesting quality hearing rehabilitation may reduce global dementia burden. @YaleSPH 1/

New paper out in The Gerontologist!

How does neighborhood stress impact aging bodies? 🏘️🧬

Our study of 14k+ older adults reveals that Blacks not only have a higher allostatic load but also a steeper longitudinal increase compared to Whites

Specialized geriatric care is proving to be a life-saver. We are very excited about these findings — it is the first national study showing that #Geriatric #Emergency Departments (GEDs) make a difference in patient outcomes.

Thank you, Dr. Omonigho Michael Bubu, for your insightful commentary on our systematic review of US-based phase III AD drug trials spanning 25+ yrs.

“The cost of inaction will grow, risking an inequitable therapeutic landscape in which those most affected again benefit last.”

[JAMA Network Open @JAMANetworkOpen]

Systematic review: Among 88 US-based phase 3 #Alzheimer disease clinical trials conducted between 1997 and 2023, nearly half did not report patient race or ethnicity, and most enrolled predominantly White patients.

CMS continually updates the CMS-HCC model (e.g., V28 in 2024–2026), adjusting how diagnoses like dementia contribute to payment. For 2027, CMS intends to refine payment methodologies, which may further affect how ADRD are managed within the overall risk-adjusted landscape.

[Xi Chen | 陈希 @xcyale]

Medicare Advantage (MA) capitation payments use risk adjustment—specifically Hierarchical Condition Categories (HCCs)—to increase monthly payments for beneficiaries with dementia, reflecting higher expected care costs.

🌟New publication alert🌟
Our study led by Wei Fu and Yuting Qian showed that reinstating #Alzheimer disease and related #dementias in 2020 decreased reported care access issues by 6.6 percentage points and reported medical financial burden by 9.2 percentage points.

1st IZA DP since the global network transitioned to its new home at @LISERinLUX. As an IZA Fellow, I fondly remember my visits to events in Bonn, Berlin, Munich, Buch/Ammersee, and the wonderful people I've met over the past 12 yrs. Wishing the new IZA@LISER chapter much success!
