Insights

Rapid eye movement (REM) sleep impacts neurobehavioral functions differently in children with and without developmental psychiatric disorders. REM sleep alterations correlate with inattention and IQ, suggesting distinct roles in brain development.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Sleep Medicine

Background:

  • Rapid eye movement (REM) sleep is linked to cognitive and behavioral functions, but its role in developmental psychiatric disorders remains unclear.
  • Understanding REM sleep's function is crucial for addressing neurodevelopmental conditions.

Purpose of the Study:

  • To investigate the association between polysomnographic (PSG) REM sleep measures and neurobehavioral functions in children with ADHD, Tourette syndrome/tic disorder (TD), comorbid ADHD/TD, and typically developing children (TDC).

Main Methods:

  • A two-night PSG was conducted on 47 children with developmental psychiatric conditions and 22 TDC, matched for age and gender.
  • Psychopathological scores and intelligence quotient (IQ) were assessed.
  • Multiple regression analyses were used to examine correlations between REM sleep parameters and neurobehavioral measures.

Main Results:

  • Children with psychiatric disorders exhibited increased REM sleep and shorter REM latency compared to TDC.
  • In children with developmental psychopathology, REM sleep proportion positively correlated with inattention and negatively with performance IQ.
  • Conversely, in TDC, REM sleep proportion negatively correlated with inattention and positively with performance IQ.

Conclusions:

  • REM sleep appears to have an opposite impact on neurobehavioral functioning depending on the presence or absence of developmental psychiatric disorders.
  • These findings suggest that REM sleep interacts differently with brain maturation pathways in children with and without psychiatric conditions.

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.

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.

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.

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).

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.
