Insights

Pediatric excessive daytime sleepiness (EDS) can stem from various sleep disorders, including narcolepsy and delayed sleep phase disorder. A comprehensive diagnostic approach is crucial for accurate identification and treatment.

Area of Science:

  • Pediatric Sleep Medicine
  • Neurology
  • Psychiatry

Background:

  • Excessive daytime sleepiness (EDS) is a common concern in pediatric populations.
  • Identifying the underlying causes of EDS is essential for effective management.
  • Sleep disorders and psychological factors can contribute to EDS in children.

Purpose of the Study:

  • To characterize the clinical and polysomnography (PSG) features of sleep disorders in children experiencing EDS.
  • To investigate the prevalence of different sleep disorders and associated conditions in this cohort.

Main Methods:

  • Retrospective review of 133 pediatric patients with EDS without obstructive sleep apnea (OSA).
  • Evaluation included overnight polysomnography (PSG) and the Multiple Sleep Latency Test.
  • Data collected encompassed medical records, sleep habit questionnaires, and depression assessments.

Main Results:

  • Narcolepsy was the most frequent diagnosis (n=78), followed by delayed sleep phase disorder (DSPD) (n=17) and idiopathic hypersomnia (n=12).
  • Over half of the patients (53/102) reported depressive feelings, with no significant difference across specific sleep disorders.
  • Thirty-four patients had normal PSG results; 17 had no identified sleep disorder, while others were diagnosed with DSPD.

Conclusions:

  • Pediatric EDS is associated with a spectrum of sleep disorders, and some cases may not have an identifiable sleep disorder.
  • Depressive feelings are prevalent in children with EDS and can impact their daily functioning.
  • A systematic diagnostic strategy, incorporating sleep habit and emotion questionnaires alongside PSG, is vital for accurate diagnosis and treatment of pediatric EDS.

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).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

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....

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...

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...
