What Are Common Sleep Disorders in Autism?

Introduction

Sleep problems are one of the most common challenges faced by individuals with autism spectrum disorder (ASD). Research shows that up to 80% of autistic individuals experience some form of sleep disturbance—far more than the general population. These disruptions can impact not only the individual’s well-being but also that of their caregivers and family.

Have you ever wondered why sleep is such a struggle for many people on the spectrum? It’s not just about tossing and turning at night—it’s often rooted in neurological, sensory, and behavioral factors that are unique to autism. From difficulty falling asleep to staying asleep, or waking up too early, sleep disorders in autism can manifest in many ways.

Insomnia in Autism

Difficulty falling asleep, staying asleep, or waking up too early

Insomnia is the most common sleep disorder experienced by individuals with autism. It often begins in early childhood and may persist into adulthood, making restful sleep a daily challenge for many families.

Why Insomnia Is So Prevalent in Autism:

• Sensory sensitivities: Sounds, textures, or light levels that may seem minor to others can overwhelm a person with autism and prevent relaxation.
• Melatonin imbalances: Many individuals on the spectrum have lower nighttime melatonin production, which disrupts their natural sleep-wake cycle.
• Anxiety and hyperarousal: Heightened stress levels, racing thoughts, and difficulty winding down can delay sleep onset.
• Rigid routines or transitions: Changes in bedtime or environment can trigger distress, making it harder to settle down.

Signs of Insomnia in Individuals with Autism:

• Taking more than 30 minutes to fall asleep
• Frequent nighttime awakenings
• Early morning waking and inability to return to sleep
• Daytime fatigue, irritability, or reduced focus

What You Can Do:

• Establish a consistent bedtime routine with calming activities (e.g., warm bath, storytime, dim lighting).
• Use melatonin supplements (under medical supervision).
• Incorporate sensory-friendly sleep aids like white noise machines or weighted blankets.
• Avoid screens and stimulating activities at least one hour before bed.

Addressing insomnia in autism requires a tailored, compassionate approach that accounts for sensory, emotional, and behavioral needs.

Circadian Rhythm Sleep-Wake Disorders in Autism

Disruptions in the internal body clock that regulates the sleep-wake cycle

Many individuals with autism experience circadian rhythm disturbances, meaning their internal biological clock doesn’t align with typical day-night cycles. This can lead to irregular sleep patterns, fatigue during the day, and nighttime restlessness.

Why Circadian Rhythm Disorders Happen in Autism:

• Melatonin production is often delayed or irregular, causing sleep onset to occur much later than normal.
• Reduced sensitivity to light cues, which are essential for regulating circadian rhythms.
• Low exposure to natural light during the day or excessive artificial light at night can confuse the body’s timing system.
• Difficulty with environmental transitions, such as seasonal changes or travel, can make rhythms more erratic.

Common Types of Circadian Rhythm Disorders in Autism:

• Delayed Sleep Phase Disorder (DSPD): Falling asleep very late and struggling to wake in the morning.
• Irregular Sleep-Wake Rhythm: Sleep times are fragmented and unpredictable.
• Non-24-Hour Sleep-Wake Disorder: A continually shifting sleep schedule, more common in individuals with low light sensitivity.

How to Support Healthy Sleep-Wake Cycles:

• Light therapy using lamps like the Philips SmartSleep to simulate sunrise/sunset.
• Consistent sleep and wake times, even on weekends.
• Daily exposure to natural light, ideally in the morning.
• Melatonin supplements timed correctly to reset the internal clock (consult a healthcare provider).

Circadian rhythm disorders in autism aren’t just about staying up late—they’re deeply rooted in biology and require structured, sensory-aware solutions.

Sleep Apnea and Breathing-Related Issues in Autism

Interrupted breathing during sleep that affects oxygen flow and overall sleep quality

Sleep-disordered breathing, especially obstructive sleep apnea (OSA), is another common concern in individuals with autism. Though it may go undiagnosed, it can have serious impacts on both physical health and behavior.

Why People with Autism May Be at Higher Risk for Sleep Apnea:

• Low muscle tone (hypotonia) affecting airway stability.
• Enlarged tonsils or adenoids, which can block the airway during sleep.
• Higher prevalence of obesity, especially in adolescents and adults with limited physical activity.
• Craniofacial differences, sometimes associated with autism or related syndromes.

Signs of Sleep Apnea in Autism:

• Loud or irregular snoring
• Gasping or choking sounds during sleep
• Restless tossing and turning
• Excessive daytime sleepiness or irritability
• Difficulty concentrating or behavioral regression

Diagnosis and Treatment Options:

• Polysomnography (overnight sleep study): The gold standard for diagnosing sleep apnea.
• CPAP (Continuous Positive Airway Pressure) machines: Helps keep airways open but may require sensory accommodations.
• Tonsillectomy/adenoidectomy: May be recommended in severe anatomical cases.
• Weight management and exercise programs tailored for children or adults on the spectrum.

Parent/Caregiver Tips:

• Keep a sleep journal to track breathing patterns, snoring, and awakenings.
• Use video baby monitors for younger children to monitor unusual sleep behavior.
• Work with a pediatric sleep specialist familiar with autism-related sensory needs.

Undiagnosed sleep apnea can mimic behavioral issues seen in autism—treating it can lead to dramatic improvements in mood, attention, and energy.

Restless Sleep & Periodic Limb Movement Disorder (PLMD) in Autism

Involuntary limb movements that disrupt sleep quality and cause nighttime awakenings

Individuals with autism often exhibit restless or fragmented sleep, and in some cases, this is due to a lesser-known condition called Periodic Limb Movement Disorder (PLMD). This neurological condition causes involuntary leg or arm movements during sleep, which can disturb rest and impact daytime functioning.

What Causes PLMD or Restless Sleep in Autism?

• Neurological differences that affect muscle regulation during sleep.
• Iron deficiency, which is strongly linked to PLMD and is also more common in autism.
• Co-existing conditions like ADHD or anxiety, both of which may increase restlessness at night.
• Overstimulation before bedtime, leading to an inability to fully “switch off.”

Signs of PLMD or Restless Sleep:

• Frequent kicking, twitching, or jerking during sleep
• Waking up tired despite being in bed all night
• Disruption of sleep for co-sleeping parents or siblings
• Daytime crankiness or hyperactivity (especially in children)

How to Manage PLMD in Autism:

• Have iron levels checked—low ferritin may require supplementation.
• Create a sensory-safe sleep environment with minimal distractions.
• Use calming strategies before bed, like massage, yoga, or weighted blankets.
• Consult a pediatric neurologist or sleep medicine specialist if symptoms persist.

Helpful Tools & Practices:

• Sleep trackers (wearables or apps) to log nighttime movements.
• Compression sheets to provide gentle resistance and reduce limb flailing.
• Low-intensity evening activities like puzzle games or coloring to wind down.

Restless sleep and PLMD can severely impact quality of life, but with the right interventions, individuals with autism can enjoy deeper, more restorative sleep.

Night Terrors and Other Parasomnias in Autism

Unusual behaviors during sleep such as screaming, walking, or confusion

Parasomnias are sleep disturbances that involve abnormal behaviors during transitions between sleep stages. In autism, these events—especially night terrors—can be more frequent and intense, often leaving caregivers alarmed and sleep-deprived.

Common Parasomnias Seen in Autism:

• Night terrors: Sudden arousals with screaming, thrashing, rapid heart rate, and confusion—usually without memory of the event.
• Sleepwalking: Walking or performing tasks while partially asleep.
• Confusional arousals: Disoriented behavior upon waking, often combined with vocal outbursts.
• Sleep talking or moaning: Can occur with or without full waking.

Why Parasomnias May Be More Common in Autism:

• Difficulty transitioning between sleep stages
• Increased anxiety or hyperarousal before bed
• Sensory overstimulation that affects REM and deep sleep cycles
• Changes in routine or environment, triggering subconscious distress

How to Manage Parasomnias in Autism:

• Maintain a consistent bedtime schedule to reduce sleep fragmentation.
• Avoid overtiredness, which is a major trigger for parasomnias.
• Create a safe sleep space—use door alarms, padded bed rails, or child-proofing if sleepwalking is a concern.
• Avoid stimulating food or drink (like sugar or caffeine) close to bedtime.
• Monitor and limit stressors—anxiety often amplifies nighttime disruptions.

When to Seek Professional Help:

• If night terrors are frequent (more than once a week).
• If there’s risk of injury due to sleepwalking or violent movements.
• If parasomnias are worsening behavior or mood during the day.

Parasomnias in autism can be distressing, but understanding the root causes—and taking proactive steps—can help make nights safer and more peaceful for everyone involved.
