The number of Americans living with Alzheimer's Disease (AD) continues to grow at an exponential rate. Currently, more than 6 million Americans have AD, and that number is expected to double by 2050. But recent research findings are beginning to show the important role diagnostics may play in the next era of AD. New diagnostic innovations could unleash a future of effective therapies, treatments, and improved outcomes for patients who suffer from this disease.

In this episode, host Dr Pat Alagia, senior medical director for Women’s and Reproductive Health at Quest Diagnostics, welcomes Dr Michael K. Racke to discuss:

  • The current tools and methods available to physicians when diagnosing AD
  • The important role of blood-based biomarkers in AD and the high impact this new testing solution can have on early diagnosis, as well as management of the disease
  • Encouraging new treatments and diagnostic pathways for AD aiming to slow disease progression and improve quality of life
  • Multilayered interventions to help prevent or delay risk of AD including a healthy diet, exercise, and cognitive stimulation
