For decades, Alzheimer’s therapies assumed more acetylcholine = better memory. Our new paper in @alzdemjournals.bsky.social challenges this dogma, showing that the cholinergic system has opposite effects on memory depending on disease stage. 📌 alz-journals.onlinelibrary.wiley.com/doi/10.1002/...
The cholinergic system exerts opposing effects on memory at different stages of disease progression in Alzheimer's and Down syndrome model systems
INTRODUCTION The long-standing cholinergic hypothesis posits that cholinergic signaling is uniformly deficient in Alzheimer's disease (AD) and Down syndrome (DS). We tested the hypothesis that this ...

New paper out! We show that EEG biomarkers interact in opposite ways in Alzheimer’s disease (AD) vs. epilepsy. This could explain why epileptiform activity is inconsistently seen in AD—and highlights the need for wideband EEG to uncover these dynamics. #HFOnews www.sciencedirect.com/science/arti...
