Insights

Children with attention-deficit/hyperactivity disorder (ADHD) exhibit more unstable sleep patterns compared to controls. Objective sleep measures accurately predicted ADHD classification, highlighting sleep instability as a key characteristic.

Area of Science:

  • Pediatric Neurology
  • Sleep Medicine
  • Neurodevelopmental Disorders

Background:

  • Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder.
  • Sleep disturbances are frequently reported in children with ADHD, but objective data on sleep-wake system stability are limited.

Purpose of the Study:

  • To objectively and subjectively compare the stability of the sleep-wake system in children with ADHD versus typically developing controls.
  • To determine if sleep measures can differentiate between children with and without ADHD.

Main Methods:

  • Actigraphy and sleep diaries were used to monitor sleep over 5 consecutive nights.
  • The study included 38 school-age boys diagnosed with ADHD and 64 control school-age boys.

Main Results:

  • The ADHD group demonstrated significantly increased instability in sleep onset, sleep duration, and true sleep compared to controls.
  • Discriminant analysis confirmed that sleep measures could significantly predict classification as either ADHD or control.

Conclusions:

  • Sleep-wake system instability is a characteristic feature of childhood ADHD.
  • These findings underscore the importance of assessing sleep disturbances in children with ADHD, given potential impacts on daytime functioning.

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:
Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...
Narcolepsy01:07

Narcolepsy

Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
Nightmares and Night Terrors01:18

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.
