Insights

Attention deficit/hyperactivity disorder (ADHD) symptoms are strongly linked to periodic limb movement disorder (PLMD) in children. Bedtime resistance may also independently contribute to ADHD symptoms by reducing sleep duration.

Area of Science:

  • Pediatric Sleep Medicine
  • Neurodevelopmental Disorders
  • Behavioral Sleep Medicine

Background:

  • Attention deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder.
  • Sleep problems are frequently reported in children with ADHD.
  • The specific sleep disorder associations with ADHD symptoms require further elucidation.

Purpose of the Study:

  • To compare the strength of association between ADHD symptoms and specific sleep disorders.
  • To investigate the relationship between ADHD symptoms, sleep disordered breathing (SDB), periodic limb movement disorder (PLMD), and bedtime resistance behaviors (BRBs).

Main Methods:

  • Parental completion of the Pediatric Sleep Questionnaire for 283 children.
  • Derivation of scales to assess risk for specific sleep disorders.
  • Correlation analysis between sleep disorder risk scales and ADHD symptoms.

Main Results:

  • Strong, independent interrelationships were found between periodic limb movement disorder (PLMD) symptoms and attention deficit/hyperactivity disorder (ADHD) symptoms.
  • Bedtime resistance behaviors (BRBs) showed potential additional contributions to ADHD symptoms.
  • These associations persisted after controlling for age, SDB, and sleepiness.

Conclusions:

  • ADHD symptoms appear particularly related to periodic limb movement disorder (PLMD).
  • Insufficient sleep duration due to bedtime resistance may independently contribute to ADHD symptoms.
  • Further research into the complex interplay between sleep disturbances and ADHD is warranted.

Sleepwalking and Sleep Talking01:17

Sleepwalking and Sleep Talking

Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...
REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Restless Leg Syndrome and Night Terrors

Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...
Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...
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.
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.
