ScienceDaily (2011-03-04) — A new study indicates that the ability of children with attention deficit hyperactivity disorder to remain vigilant and attentive deteriorated significantly after losing less than one hour of nightly sleep for a week.

“Moderate sleep restriction leads to a detectable negative impact on the neurobehavioral functioning of children with ADHD and healthy controls, leading to a clinical level of impairment in children with ADHD,” said lead author and principal investigator Reut Gruber, PhD, assistant professor in the department of psychiatry at McGill University and director of the Attention, Behavior and Sleep Laboratory at Douglas Mental Health University Institute in Montreal, Québec.
