REM-sleep motor disorder in children

In 1986, Schenck and coworkers described REM-sleep behavior disorder as a treatable parasomnia affecting older males. This disorder is characterized by intermittent loss of the muscle atonia, which normally characterizes the rapid eye movement (REM) sleep state. Complex motor behaviors occur that are often injurious and are associated with dreaming. We have identified five children who meet the criteria for REM-sleep behavior disorder and describe the clinical and polysomnographic characteristics of these patients, along with corresponding polysomnographic characteristics of matched comparison subjects.
