We have seen data associating attention-deficit/hyperactivity disorder with sleep disorders, and many experts believe that a sleep assessment should be performed routinely in these patients. Is it all about insufficient sleep and sleep patterns? Or are there polysomnographic differences that may identify those who are at risk for ADHD? Can poor sleep in early childhood predict a diagnosis of ADHD in adolescence? Dr. Jessica Lundsford-Avery shares her research in this field and helps us understand the relationship between childhood sleep and adolescent ADHD.
