The science of Alzheimer’s disease and dementia is changing rapidly. Advances in biomarkers, diagnostics, treatments, and prevention could allow clinicians to identify disease earlier than ever before, sometimes even before noticeable symptoms emerge.

In this special episode of The Health Advocates, recorded for Steven Newmark’s visit to London for the 2026 World Dementia Council Summit, Steven explores what this new era could mean for patients, caregivers, and health systems.

What happens when someone receives a diagnosis before they feel sick? Are health systems prepared for greater demand for testing and treatment? How could AI, digital tools, and biomarkers change dementia care? And how do we make sure scientific progress reaches patients equitably?

Steven examines why the next challenge in dementia may not simply be advancing the science, but building the policies, infrastructure, workforce, and patient support needed to put that science into practice.

S9, Ep 23- The New Dementia Patient: Rethinking Diagnosis, Treatment, and Care

Colorectal cancer screening can save lives, yet millions of eligible Americans still do not complete recommended screening. Could a simple blood draw help reach some of the people who currently go unscreened?

In this episode of The Health Advocates, Steven Newmark speaks with Dr. Sam Asgarian, Chief Medical Officer at Guardant Health, and Oliver Rocroi, Advocacy Relations Officer at Guardant Health, about the emerging role of blood-based colorectal cancer screening.

They discuss how these tests work, who may qualify, their benefits and limitations, what happens after a positive result, and how blood-based testing fits alongside colonoscopy and stool-based screening. The conversation also explores the broader public health question of whether giving people additional screening options could help overcome barriers and lead to more cancers being detected earlier.

Plus, Oliver rejoins the program with an important update on recent changes to the U.S. Preventive Services Task Force and what those developments could mean for future consideration of newer colorectal cancer screening options.

The message for patients remains simple: understand your risk, know your screening options, and talk with your healthcare provider about the approach that makes sense for you.

S9, Ep 22- Could a Blood Test Change Colorectal Cancer Screening? What Patients Should Know

Osteoarthritis affects millions of people, but living with OA can involve much more than joint pain. It can change how people work, exercise, socialize, sleep, and participate in everyday life. And for many patients, the path from conservative treatments to possible joint replacement can feel frustrating and unclear. 

In this episode of The Health Advocates, we speak with orthopedic surgeon and researcher Dr. Vinod Dasa about what patients should understand about osteoarthritis today. We discuss how OA develops, when to seek care, available treatment options, shared decision-making, gaps in care between symptom management and surgery, and the barriers that can affect access to treatment. 

Dr. Dasa also shares his perspective on innovation in osteoarthritis and what emerging approaches could mean for patients in the years ahead. 

If you or someone you care about is living with osteoarthritis, this conversation offers practical questions to bring to your next appointment and a look at why expanding treatment options matters.

S9, Ep 21-  Osteoarthritis: Treatment, Innovation, and Giving Patients More Options

As fall approaches, flu and COVID-19 are once again moving to the forefront of public health. In this episode of The Health Advocates, Steven Newmark looks at what the Southern Hemisphere’s flu season may tell us about the months ahead, how this year’s flu vaccine has been updated, and when people should consider getting vaccinated.

He also breaks down the newest COVID-19 vaccine, including which variant it targets, when it will be available, who is currently eligible to receive it in the United States, and how much protection we can realistically expect against infection and severe illness.

The episode also explains why respiratory viruses often gain momentum as children return to school and people spend more time indoors, with practical guidance for patients, caregivers, and people living with chronic illness as they prepare for fall virus season.
