RESULTS Conjunction analyses revealed overlapping hypoactivations between ADHD and sleep loss in executive function regions , notably the dorsal anterior cingulate cortex .
Sleep deprivation , however , was associated with significantly exaggerated hyperactivation in the thalamus .
Our study indicates that ADHD and sleep deprivation share a common neural signature : hypoactivation of executive function neuroanatomy .
In contrast , sleep loss , but not ADHD , was associated with thalamic hyperactivations , intimating a potential compensatory response in sleep loss not present in ADHD .
STUDY OBJECTIVES Sleep disruption is common in attention deficit hyperactivity disorder ( ADHD ) .
Likewise , deficits in attention are a hallmark of sleep deprivation in healthy individuals .
Whether ADHD and sleep deprivation modulate common , or disparate , neural systems is unknown .
No study has yet utilized functional magnetic resonance imaging ( fMRI ) to investigate sleep loss in ADHD .
We address this gap by performing a novel meta- analysis to compare patterns of fMRI activation during sleep deprivation and ADHD .
Effects of Acute Sleep Restriction on Behavior, Sustained Attention, and Response Inhibition in Children
This study examined the effects of acute sleep restriction on the daytime behavior and performance of healthy children and adolescents . 82 participants ( 8 to 15 years of age ) completed 5 nights of baseline sleep and were r and omly assigned to Optimized ( 10 hr . ) or Restricted ( 4 hr . ) sleep for an overnight lab visit . Behavior , performance , and sleepiness were assessed the following day . Sleep restriction was associated with shorter daytime sleep latency , increased subjective sleepiness , and increased sleepy and inattentive behaviors but was not associated with increased hyperactive-impulsive behavior or impaired performance on tests of response inhibition and sustained attention . Results are discussed in terms of current theories regarding effects of inadequate or disturbed sleep among children and adolescents
