An estimated 45% of dementia cases are preventable – find out how you can reduce your risk by targeting these fourteen modifiable factors. In Episode #337, I sit down with Dr Kellyann Niotis, the first fellowship-trained preventive neurologist, to explore the latest research on dementia prevention and how simple lifestyle changes can significantly reduce your risk of cognitive decline.
“Neurodegenerative diseases are very similar to cardiovascular disease in that they form decades before – in the body – the first obvious symptoms develop.”
Dr Kellyann Niotis leads the preventive neurology program within Dr Peter Attia’s medical practice, Early Medical, where she focuses on the applied science of longevity. She is also the Director of Parkinson’s Disease & Lewy Body Dementia Prevention Research at the Institute for Neurodegenerative Diseases Florida. Dr Niotis was previously the manager of the country’s first Alzheimer’s Prevention Clinic at Weill Cornell Medical College and is the first fellowship-trained preventive neurologist in the U.S. She has published extensively in peer-reviewed journals and her expertise has been featured in major media outlets, including CNN.
“It’s never too late to start thinking about your brain; of course, the earlier you start the better.”
In this episode, we break down the fourteen modifiable risk factors for dementia as outlined in the latest Lancet Commission report. From managing LDL cholesterol and staying physically active to addressing hearing loss and maintaining mental health, Dr Niotis explains how these factors can help reduce your risk of dementia. You’ll also learn about the links between nutrition, sleep, and brain health, and why it’s never too early – or too late – to start taking care of your brain.

Additional notes
Recent research suggests that certain blood pressure medications may offer superior protection against dementia. These include:
- Thiazides
- Angiotensin 1 receptor blockers (ARBs)
- Dihydropterin calcium channel blockers
These compounds are being studied for their potential benefits in preventing dementia, providing further insight into how we can proactively protect our brain health.
