Dr. Richard Isaacson was featured by CNN discussing new research linking excessive daytime sleepiness to motoric cognitive risk syndrome, a condition characterized by slower walking speed and memory complaints that may precede dementia. While the study found an association rather than a cause-and-effect relationship, it highlights the growing importance of sleep as an early indicator of brain health.

Dr. Isaacson emphasized that sleep disturbances can be an early warning sign of underlying neurological changes and encouraged people experiencing persistent daytime sleepiness to speak with their healthcare provider. He noted that sleep evaluations—including questionnaires and, when appropriate, at-home or in-lab sleep studies—can help identify treatable sleep disorders, and that both medical and non-drug approaches may improve sleep and support long-term cognitive health.
