MDPRC retreat 2025

Hey everyone! Join our journal club on October 10th (12pm EST) to discuss two short papers on weight stigma and language. JC is drop in format: come once, come when you can. Reach out to @shanaadise.bsky.social or myself to get the zoom link and papers. Please share! @ssibsociety.bsky.social

Obesity increases the risk of Alzheimer’s disease, yet it remained unclear whether #obesity causes #neurodegeneration through the same mechanisms. A new study by Filip Morys in the lab of Alain Dagher used #OpenScience brain data to find the answer. 📑 journals.sagepub.com/doi/full/10....

Our big behavioral precision mapping preprint is out. Based on 1,486,950 observed choices in a reward learning task, we show that BMI is associated with higher and more variable learning rates. Binge eating was associated with lower reward sensitivity. #neuroskyence 🩺 www.medrxiv.org/content/10.1...

🧵 Beautiful new preprint by @marishishi.bsky.social on the genetic architecture of impulsivity. With the UCSD team of Sandra Sanchez-Roige, Abe Palmer et al. and Lang Liu, Ziv Gan-Or @ukuvainik.bsky.social @filipkmorys.bsky.social @misicbata.bsky.social and others www.biorxiv.org/content/10.1...

Ravitsemus | Pitkälle jalostettu valmisruoka voi aiheuttaa rakenteellisia muutoksia aivoissa, kertoo tuore tutkimus

Ongelmallisia ovat esimerkiksi prosessoidut lihatuotteet, jotka sisältävät paljon kemiallisesti muokattuja ainesosia ja lisäaineita.

New research from The Neuro shows that eating lots of ultra-processed foods is linked not just to obesity, but to changes in brain structure related to appetite and metabolism. These brain effects may help explain why these foods drive overeating. Learn more: www.nature.com/articles/s44...

New paper! In ~30k people from UKBB we show that ultra-processed food consumption 🍔 is associated with structural integrity of feeding-related brain regions (Hpth/NAcc) 🧠 Some of the changes occur independent of obesity, through inflammation. www.nature.com/articles/s44... @alaindagher.bsky.social

Preprint w/ @filipkmorys.bsky.social on interplay of adiposity and AD genetics. Genetic risk ascertained from MAPT (H1), ApoE (E4) and polygenic risk score. Both adiposity and genetic risk are associated with brain atrophy in adulthood, but effects appear independent. www.medrxiv.org/content/10.1...

Obesity-related brain atrophy occurs through mechanisms independent of Alzheimer's disease pathology

Obesity increases the risk for Alzheimer's disease (AD) and related dementias, likely through structural brain changes in the same regions as AD. The mechanisms underpinning brain atrophy in AD involv...

I made a starter pack for the Society for the Study of Ingestive Behavior #SSIB for all interested in being a #SSIBling. Please let me know if you would like to join the starter pack! go.bsky.app/8Zvp83e
