In this informative discussion, Dr.Sanjeev Goel MD and Carmelia Ray delve into the topic of Alzheimer's and the genetic aspects that contribute to the risk of developing this disease. We focus on Chris Hemsworth's recent revelation on his show, "Limitless", about his genetic predisposition towards Alzheimer's. This has sparked a broader conversation about the importance of genetic testing and preventive measures. We explore the role of the APOE4 allele, its impact on Alzheimer's risk, and its presence in Hemsworth's genetic makeup. Additionally, we discuss lifestyle modifications and potential treatments for Alzheimer's. This video also briefly addresses Bruce Willis's recent diagnosis of frontotemporal dementia, a distinct but related condition. Join us as we unravel the complexities of these neurological disorders and discuss potential preventative measures.
