Insights

Melatonin effectively improves sleep in children with neurodevelopmental disorders, offering short-term benefits for sleep latency and duration. Other medications show limited efficacy for pediatric sleep issues.

Area of Science:

  • Pediatric Sleep Medicine
  • Neurodevelopmental Disorders Pharmacology
  • Clinical Trial Analysis

Background:

  • Sleep problems are prevalent in children, particularly those with neurodevelopmental disorders, impacting behavior and quality of life.
  • Pharmacologic interventions are often considered for pediatric sleep disorders, necessitating evidence-based efficacy and safety data.

Purpose of the Study:

  • To systematically review the efficacy and harms of pharmacologic treatments for sleep disorders in children and adolescents.
  • To evaluate specific medications including zolpidem, eszopiclone, diphenhydramine, and melatonin.

Main Methods:

  • Systematic review of 22 placebo-controlled randomized controlled trials (RCTs) published through June 2018.
  • Searches conducted in MEDLINE, Cochrane Library, and PsycINFO databases.
  • Included 1758 children and adolescents (mean age 8.2 years) across trials ranging from 1 to 13 weeks.

Main Results:

  • Zolpidem and eszopiclone showed no sleep improvement in children with attention-deficit/hyperactivity disorder (ADHD), though zolpidem improved Clinical Global Impression scores.
  • Diphenhydramine demonstrated minor improvements in sleep latency and duration (8-10 minutes) in a small RCT.
  • Melatonin significantly improved sleep latency (median 28 min) and duration (median 33 min) in 19 RCTs, particularly in children with autism spectrum disorder (ASD) and neurodevelopmental disorders.
  • Adverse events were infrequent with melatonin but more common with eszopiclone and zolpidem.

Conclusions:

  • Melatonin is a useful short-term treatment for specific sleep outcomes in children, especially those with comorbid ASD and neurodevelopmental disorders.
  • Current evidence for zolpidem, eszopiclone, and diphenhydramine in pediatric sleep disorders is limited or shows minimal benefit.
  • Further research is needed to adequately study other pharmacologic interventions and long-term outcomes for pediatric sleep disorders.

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.

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...

Treatment Strategies for Psychological Disorders

Treatment approaches for psychological disorders fall into three main categories: psychological, biological, and sociocultural. Each approach targets different aspects of mental health, requiring varying levels of education and training.
Psychological therapies focus on modifying emotions, thoughts, and behaviors through talking, interpreting, listening, rewarding, challenging, and modeling. Clinical psychologists, counselors, and social workers commonly practice psychotherapy. Clinical...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

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...
