📣Our new paper, led by Victoria Tennant, sets tau cut points in a large cohort of Hispanic, and non-Hispanic Black and White participants using PI-2620 PET. ⭐️The ability of our tau cut points to distinguish cognitively impaired vs unimpaired people varied by ethnoracial group.

👋Welcome to Patrick Walsh, who has joined our lab as a full time Project Assistant! Patrick has an MS in Neuroimaging and Informatics from USC (@USCNIIN). He will be working on projects whose goal is to better understand risk for Alzheimer's disease and related dementias 🧠

New paper - led by Dr. Allie Clark: bit.ly/3SGgNJg -People w/ low resources & high distress had smaller hippocampi & thinner cortex vs people w/ more resources & less distress. -Low resources (regardless of distress) were associated w/ faster brain aging.

🎉Congrats to Noelle Lee, who will start a software development engineer internship this summer! Noelle has been with the lab 4 years and her amazingly analytical mind, careful work, and fun personality made the lab a better place 🌟🧠. We miss you already, Noelle!

📣 New paper led by Dillys Lui (@KristineYaffe's lab) bit.ly/3HeZFb1 -⬆️light sleep% & longer REM sleep latency = thinner cortex in AD-related regions -⬆️ deep sleep % = thicker cortex (same regions) -⬆️ apnea hypopnea index in rapid eye movement sleep = ⬆️ WMH volume.

🎉Congrats to Phd student, Amaryllis Tsiknia @TsikniaAA, who led our new paper bit.ly/3ZndVVh studying how diabetes relates to cortical thickness in Hispanic & non-Hispanic Black & White older adults! Read more here: bit.ly/3GS0Ddj More on our findings soon...

🧠 Our new study from @TsikniaAA @MeredithBraskie & more finds a strong link between type 2 diabetes & brain atrophy in older adults—especially in memory-related regions. Managing blood sugar could be key to protecting brain health as we age. Learn more 👉 bit.ly/3GS0Ddj
