In this episode of Longevity by Design, hosts Ashley Reaver and Dr. Gil Blander welcome Dr. Julie Andersen, a distinguished neuroscientist at the Buck Institute for Research on Aging, who discusses her groundbreaking work on neurodegenerative diseases, focusing on Parkinson's and Alzheimer's. She explains how the field of geroscience is transforming our understanding of aging, revealing that common underlying processes in various diseases could lead to universal therapeutic approaches.Dr. Andersen dives into the gut-brain connection, highlighting how gut health significantly impacts brain aging and the progression of neurodegenerative diseases. She also emphasizes the importance of cellular senescence, a process where aging cells stop dividing, contributing to diseases like Alzheimer's. Her research explores innovative ways to slow or prevent these processes, paving the way for new treatments.The episode concludes with Dr. Andersen advocating for lifestyle interventions, particularly exercise, as powerful tools in preventing neurodegenerative diseases. She underscores the potential of personalized medicine in tailoring treatments to individual aging patterns, offering hope for more effective and targeted therapies.Episode highlights:Introduction: 00:00:00Dementia as a side effect of aging: 00:06:00Dementia prevalence in the population: 00:10:00The environment and Alzheimer's disease: 00:15:00Biological sex effect on Dementia 00:17:00Ethnicity effect on Dementia 00:18:00What to expect when you are diagnosed with Dementia 00:19:00Biomarkers for Dementia 00:26:00The connection between the hallmarks of aging and Dementia: 00:30:00 Exercise and Dementia: 00:34:00disruption of REM sleep as an early sign of Parkinson's: 00:37:00What is the current treatment for Parkinson's: 00:38:00Cellular senescence and neurodegenerative diseases: 00:42:00Beta amyloid plaques and Alzheimer's disease: 00:50:00Autophagy and dementia: 01:00:00What would you recommend to a person who like to live better and longer: 01:08:00
