Dr. Richard Isaacson was featured by CNN discussing new research suggesting that losing deep, slow-wave sleep with age may increase the risk of developing dementia. The study found that each annual decline in slow-wave sleep was associated with a higher risk of dementia over nearly two decades of follow-up, reinforcing the growing body of evidence linking sleep quality to long-term brain health.

Commenting on the findings, Dr. Isaacson emphasized that both the quantity and quality of sleep are important for protecting cognitive health. He noted that monitoring sleep quality, identifying underlying sleep disorders, and adopting healthy sleep habits may help support brain health as part of a broader strategy that includes nutrition, exercise, and cardiovascular risk reduction.
