How Ketones Support the Aging Brain & Psychiatric Meds Disrupt Brain Energy - Dr. Stephen Cunnane

Do psychiatric medications alter brain energy and metabolic health? Dr. Stephen Cunnane, a professor and researcher at the University of Sherbrooke, has been at the forefront of studying glucose and ketone metabolism in the aging brain, pioneering advanced imaging techniques to measure how the brain utilizes these critical energy sources with neurodegenerative conditions like Alzheimer’s and Parkinson’s. While glucose PET imaging has long been used to study brain energy metabolism, Dr. Cunnane’s team was the first to develop ketone PET imaging, allowing researchers to look at the relationship between glucose and ketone metabolism in the brain and understand how ketones support brain function when it struggles to use glucose for energy. Now, Dr. Cunnane has turned his attention to metabolic psychiatry and is working on a new study looking at brain energy metabolism in individuals experiencing first-episode psychosis. This study will allow researchers insights into the metabolic state of the brain at the onset of major mental illness and how psychiatric medications influence brain energy use. In this episode, you will learn: How the brain uses fuel as we age – Why glucose metabolism declines over time and how ketones may compensate in aging and neurodegenerative conditions. The first ketone PET imaging studies – How Dr. Cunnane’s team developed a method to directly measure ketone uptake in the brain and compare it to glucose metabolism Psychosis and brain energy metabolism – Examining glucose and ketone utilization in first-episode psychosis before and after antipsychotic treatment. Carbohydrate reduction in older adults – Findings from a study showing how moderate carb restriction improved metabolic and mental health in retirement home residents independent of weight loss. Parkinson’s disease and ketones – Investigating how exercise, exogenous ketones, and carbohydrate restriction may enhance brain energy supply and improve symptoms. Dr. Cunnane has been a pioneer in the field of ketogenic therapy and brain energy. In addition to all the incredible work he is doing in the aging brain, we are excited to see his new research focusing on such critical components of metabolic psychiatry.
