Dr. De Felice led innovative studies on the actions of hormones in Alzheimer’s disease. She conducted seminal work on the mechanisms leading to defective insulin signaling in Alzheimer’s disease. Her recent study showing that irisin, an exercise-linked hormone, has protective actions in AD has received widespread interest from the scientific community and media all over the World. Her studies, along with clinical observations, have contribute to understand how neuronal dysfunction occurs in the brains of AD patients and are contributing to comprehend how lifestyle interventions, in particular physical exercise, have the potential to preserve brain health and prevent or delay AD.
