Insomnia in Children Affected by Autism Spectrum Disorder: The Role of Melatonin in Treatment



For many families with children on the Autism Spectrum Disorder (ASD) spectrum, bedtime can be a battleground. Difficulty falling asleep, frequent awakenings, and restless nights are all too common. These sleep issues not only disrupt the child’s well-being, but also take a toll on caregivers.

A new ray of hope emerges from a May 2024 research paper titled “Insomnia in Children Affected by Autism Spectrum Disorder: The Role of Melatonin in Treatment.” This study sheds light on the effectiveness and safety of melatonin as a treatment option for children with ASD experiencing insomnia.

Unveiling the Insomnia Struggle in Children with ASD


Insomnia, characterized by trouble falling asleep or staying asleep, is a significant concern for children with ASD. Estimates suggest that compared to neurotypical children, children with ASD are two to three times more likely to experience sleep problems.

The reasons behind this disparity are multi-faceted:

  • Disrupted Sleep-Wake Cycles: Children with ASD may have difficulty regulating their circadian rhythms, the internal body clock that governs sleep and wakefulness. This can lead to inconsistent sleep schedules and difficulty falling asleep at appropriate times.
  • Sensory Sensitivities: The world can be an overwhelming place for children with ASD. Bright lights, loud noises, or uncomfortable textures in the bedroom environment can make it challenging to relax and fall asleep.
  • Anxiety and Repetitive Behaviors: Anxiety, a common co-occurring condition with ASD, can fuel worry and make it difficult to quiet the mind for sleep. Additionally, repetitive behaviors that interfere with bedtime routines can disrupt sleep patterns.

Melatonin: A Potential Ally for Sleep


Melatonin is a naturally occurring hormone produced in the pineal gland, a tiny pinecone-shaped structure located deep within the brain. Melatonin plays a crucial role in regulating sleep-wake cycles.

Researchers have been exploring the potential of melatonin as a treatment for insomnia in children with ASD for some time. The May 2024 study, led by Dr. Oliviero Bruni and colleagues, adds valuable insights to this field.

Here are the key takeaways from the research:

  • Melatonin Offers Relief: The study found melatonin to be an effective and safe treatment for insomnia in children with ASD. This benefit was observed for both short-term and long-term use.
  • Prolonged-Release Formulation Shines: Prolonged-release melatonin appears to be the most effective option. This formulation is specifically designed for gradual release of melatonin into the bloodstream, mimicking the body’s natural production. It is already approved for use in children with ASD and sleep problems, ages 2-18.
  • Improved Sleep Quality: The benefits of melatonin included falling asleep faster (improved sleep latency), increased total sleep duration, and improved sleep efficiency (less time awake during sleep). The prolonged-release form of melatonin was particularly effective in reducing nighttime awakenings.
  • Beyond Sleep: Daytime Benefits: Some studies suggest that improved sleep with melatonin use can lead to better daytime functioning in children with ASD. This may involve improved mood, reduced behavioral difficulties, and enhanced focus.
  • Purity Matters: The study emphasizes the importance of using high-purity melatonin, especially pharmaceutical-grade formulations. Concerns about accidental ingestion of melatonin highlight the need for safe and reliable products.
  • Unlocking the Mechanism: The research delves into the emerging science behind how melatonin works in the body. Understanding these mechanisms paves the way for the development of even more targeted treatment approaches in the future.

Considering Melatonin for Your Child with ASD


While the May 2024 study is encouraging, it’s important to approach melatonin use with informed caution. Here are some key points to remember:

  • Consult a Healthcare Professional: Before starting any new supplement or medication, discuss your child’s sleep struggles with a healthcare professional. They can assess your child’s individual needs and determine if melatonin is an appropriate option.
  • Medication Interactions: Melatonin may interact with other medications your child is taking. It’s crucial to disclose all medications to your doctor to avoid potential complications.
  • Dosage and Formulation: The appropriate dosage and formulation of melatonin will vary depending on your child’s age, weight, and specific sleep issues. A healthcare professional can determine the best approach for your child.
  • Melatonin is a Tool: Melatonin should be used alongside behavioral interventions for optimal sleep improvement. These interventions may include establishing a consistent sleep schedule, creating a calming bedtime routine, and addressing any sensory sensitivities that disrupt sleep.
