Abstract

Introduction

We have previously found an increased rapid eye movement (REM) sleep in children with attention-deficit/hyperactivity disorder (ADHD).

Objectives

To further investigate sleep characteristics in children with ADHD and their association with cognitive and neurobehavioral functions.

Aims

We asked whether and how REM sleep might have been associated with cognitive ability and neurobehavioral functions in children with ADHD compared with healthy children.

Methods

Twenty-three children with ADHD and 21 healthy controls underwent a two-night polysomnography and completed a number of standardized tests for cognitive and neurobehavioral functioning.

Results

Compared with controls, ADHD children exhibited a greater amount of REM sleep. In the ADHD group, the increased amount of REM sleep correlated positively with psychopathological scores (inattention) and negatively with performance intelligence quotient (IQ) (Fig. 1).

In contrast, in the healthy controls, the REM sleep amount correlated positively with performance IQ and negatively with psychopathological scores (inattention) (Fig. 2).

Conclusions

We conclude that REM sleep may have a bi-directional role in cognition and neurobehavioral functioning during childhood depending on the presence or absence of psychopathology.
