In this episode, Tommy delves into the complexities of age-related cognitive decline and explores interventions to counteract it. Drawing from his experience working with Formula 1 drivers, he highlights the connection between cognitive function and the right type of demands and training leading to improvement. Next, he explores the various theories on the different types of pathology in dementia and neurodegeneration. He makes the case that a large fraction of dementia is preventable through lifestyle choices and nutrient status, and provides an in-depth overview of interventions and supplements that support cognitive function. Finally, he provides a comprehensive overview of head injuries, including concussions and traumatic brain injuries (TBIs), discussing symptoms, how to mitigate damage following an incident, and long-term management.
