Replay: How Genes and Daily Choices Shape Dementia Risk with Dr. Robert Sutherland

Dr. Robert Sutherland, neuroscientist and director at the Canadian Centre for Behavioural Neuroscience, joins us to share how his work and life have been shaped by dementia. He reflects on the impact of dementia in his own family and explains what current science tells us about causes, prevention and treatment.

Dr. Sutherland discusses how research is evolving, what surprises him most in the lab and why addressing dementia requires more than a single solution. He also speaks to the importance of improving care, reducing misinformation and expanding access to services that can help.

Key Takeaways

Multiple Causes – Alzheimer’s isn’t one disease with one cause. Many processes in the brain can lead to it. Amyloid and Tau – These proteins play a role, but more amyloid doesn’t always mean worse symptoms. Modifiable Risk – Hearing loss, hypertension, and heart health matter. Lifestyle changes can reduce risk. Care and Access – People often aren’t prescribed helpful treatments early enough. Better systems are needed. Long-Term Hope – With continued research and collaboration, he hopes to slow or even prevent most cases.
