The Impact of Ketogenic Diets on Cognitive Behavior, Motor Function, and Blood Lipids

BUFFALO, NY- April 17, 2024 – A new #researchpaper was #published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 7, entitled, “The impact of continuous and intermittent ketogenic diets on cognitive behavior, motor function, and blood lipids in TgF344-AD rats.” Studies suggest that ketogenic diets (KD) may improve memory in mouse models of aging and Alzheimer’s disease (AD). In this new study, researchers Jennifer M. Rutkowsky, Zabrisky Roland, Anthony Valenzuela, An B. Nguyen, Heui Hye Park, Natalie Six, Ilknur Dursun, Kyoungmi Kim, Pamela J. Lein, and Jon J. Ramsey from the University of California Davis and Istinye University determined whether a continuous or intermittent KD (IKD) enhanced cognitive behavior in the TgF344-AD rat model of AD. “[...] it remains to be determined whether long-term consumption of a ketogenic diet can mitigate declines in cognitive or motor behavior in a rat model of AD. Therefore, the current study aimed to determine whether a KD improves cognitive or motor behavior in the TgF344-AD rat.” At 6 months-old, TgF344-AD and wild-type (WT) littermates were placed on a control (CD), KD, or IKD (morning CD and afternoon KD) provided as two meals per day for 2 or 6 months. Cognitive and motor behavior and circulating β-hydroxybutyrate (BHB), AD biomarkers and blood lipids were assessed. Animals on a KD diet had elevated circulating BHB, with IKD levels intermediate to CD and KD. TgF344-AD rats displayed impaired spatial learning memory in the Barnes maze at 8 and 12 months of age and impaired motor coordination at 12 months of age. Neither KD nor IKD improved performance compared to CD. At 12 months of age, TgF344-AD animals had elevated blood lipids. IKD reduced lipids to WT levels with KD further reducing cholesterol below WT levels. “[...] the IKD or KD did not improve motor coordination or spatial learning memory compared to the control diet. However, KD, and to a lesser extent IKD, mitigated elevations in plasma lipids in the TgF344-AD rats. Furthermore, the KD diet decreased plasma levels of total Tau in females.” DOI - https://doi.org/10.18632/aging.205741 Corresponding author - Jennifer M.
