Sleep is an incredibly complex process that goes beyond body rest. Disturbance in sleep can lead to several short-term and long-term consequences. Research suggests that neurodivergent individuals are more prone to sleep issues. For instance, over half of children with autism have one or more chronic sleep problems, and these issues often carry over into teenage and adult years. Similarly, an estimated 25% to 50% of people with ADHD experience sleep problems.
Neurodivergent individuals may need more sleep due to unique brain structures that cause delays in the circadian rhythm or changes in natural melatonin production. Additionally, stimulant and psychotropic medications commonly prescribed for neurodivergence can have significant sleep-disrupting side effects.
Addressing sleep issues is crucial for neurodivergent individuals as it can impact their executive functioning and social skills.

What You'll Learn
Sleep and executive functioning
Neurodivergent individuals often experience sleep issues, with research indicating that over half of autistic children and 25-50% of people with ADHD have sleep problems. These issues can persist into adulthood, and the resulting sleep deprivation can negatively impact executive functioning.
For example, a lack of sleep can lead to difficulties with planning and attentional control, making it harder to maintain the habits and behaviours that support healthy sleep. This can create a negative cycle, where sleep deprivation exacerbates executive functioning challenges, further disrupting sleep patterns.
Additionally, neurodivergence can impact sleep patterns due to structural differences in the brain and chemical production. Delays in the circadian rhythm, changes in melatonin production, and medication side effects can all contribute to sleep disturbances.
To improve sleep and support executive functioning, it is essential to establish healthy sleep habits and routines. This includes maintaining a consistent sleep schedule, limiting screen time before bed, and creating a relaxing bedtime routine. Addressing sleep issues is crucial for neurodivergent individuals to enhance their executive functioning and overall well-being.

Sleep and autism
Sleep is an essential component of physical and mental health, alongside good nutrition and exercise. However, for autistic people, sleep can be elusive. Research suggests that around 80% of autistic children experience sleep difficulties, and these issues often persist into adulthood.
Autistic people may struggle with sleep due to difficulties with relaxing or winding down, irregular melatonin levels, and irregular circadian rhythms. They may also have co-occurring conditions such as gastrointestinal problems, ADHD, or anxiety, which are known to disrupt sleep. Sensory sensitivities to light, sound, or touch can also make it challenging to fall and stay asleep.
The Impact of Sleep Problems
Sleep problems can worsen behavioral challenges, interfere with learning, and decrease the overall quality of life for autistic individuals. Research shows that autistic children who do not get enough sleep exhibit more severe repetitive behaviors and have a tougher time making friends. They also tend to score lower on intelligence tests and display higher levels of hyperactivity and inattentiveness.
Strategies to Improve Sleep
- Establish a bedtime routine: A consistent, predictable, and relaxing bedtime routine can help signal to the body that it's time to wind down and prepare for sleep. This routine should be relatively short (20-30 minutes) and include activities such as reading or listening to quiet music.
- Create a conducive sleep environment: The bedroom should be dark, quiet, and cool to minimize sensory distractions and promote comfort.
- Maintain a regular sleep/wake schedule: Stick to consistent bed and wake-up times, even on weekends, to establish a sleep schedule that makes falling and staying asleep more reliable.
- Limit screen time before bed: Avoid watching TV, playing video games, or using electronic devices before bed, as the blue light emitted by these devices can disrupt melatonin production and delay sleep.
- Engage in daytime exercise: Exercise can help make it easier to fall asleep, and it promotes deeper sleep. However, avoid exercising too close to bedtime as it may have a stimulating effect.
- Avoid caffeine: Caffeine interferes with the body's natural sleep signals and can increase anxiety, making it more difficult to fall and stay asleep.
- Limit naps: While naps are beneficial for preschool children, they can interfere with sleep for older kids and teenagers.
- Address medical or psychiatric issues: Certain medications or underlying medical conditions can impact sleep. It's important to address these issues and make any necessary adjustments to medications or treatment plans.
- Melatonin supplements: Melatonin is a natural hormone that controls sleep. Taking melatonin supplements can help regulate sleep patterns and improve sleep quality. However, it's important to consult a doctor before taking any supplements.
By implementing these strategies and working closely with healthcare professionals, autistic individuals and their families can improve their sleep habits and overall well-being.

Sleep and ADHD
Sleep problems are common in people with ADHD, with an estimated 25% to 50% of people with ADHD experiencing sleep issues. These sleep issues can range from insomnia to secondary sleep conditions. Sleep problems in people with ADHD can be caused by several factors, including delayed circadian rhythm, changes in melatonin production, medication side effects, and co-occurring mental health disorders.
Difficulty Falling Asleep
About three-fourths of adults with ADHD report an inability to "shut off my mind" at night, with their thoughts jumping from one worry to another. This can lead to a misdiagnosis of a mood disorder when it is actually the mental restlessness of ADHD. Prior to puberty, 10% to 15% of children with ADHD have trouble falling asleep, which increases to 50% by age 12.
Restless Sleep
When individuals with ADHD do fall asleep, their sleep is often restless, waking up at any noise and tossing and turning throughout the night. Their sleep is not refreshing, and they wake up as tired as when they went to bed.
Difficulty Waking Up
More than 80% of adults with ADHD in clinical settings report multiple awakenings until about 4 a.m., after which they fall into a deep sleep and have extreme difficulty getting up in the morning. They may sleep through multiple alarms and be irritable when woken up.
Treatment Options
Treatment options for ADHD-related sleep problems include behavioural interventions such as establishing a consistent bedtime routine and improving sleep hygiene, as well as pharmacological interventions such as melatonin, prescription medications, and stimulant-class medications.

Sleep and intellectual disabilities
Sleep is vital for physical and mental health. Research shows that sleep disorders and difficulties are prevalent among adults with intellectual disabilities. Despite this, sleep is often overlooked in this group, and its disorders are considered challenging to treat. The evidence base for sleep disorders in adults with intellectual disabilities is limited.
Sleep disorders, including sleep-disordered breathing and insomnia, are more common in adults with intellectual disabilities than in the general population. One systematic review found that 32% of individuals with intellectual disabilities experienced multiple sleep problems. Adults with intellectual disabilities experience more fragmented sleep compared to the general population, and those with more severe intellectual disabilities are at higher risk of sleep disturbances.
Autism spectrum disorder (ASD) is a common comorbidity in people with intellectual disabilities, with a prevalence of up to 39% in adults with moderate to profound intellectual disabilities. Sleep problems persist across a lifetime in individuals with ASD. A review by Cohen et al. discussed the multi-factorial aetiology for sleep problems in those with ASD, including evidence of biological abnormalities in the timing of melatonin secretion and sleep disruption secondary to co-occurring medical and psychiatric conditions.
Additionally, individuals with intellectual disabilities have a higher prevalence of attention-deficit hyperactivity disorder (ADHD) than those without, with reported rates of up to 19.6%. Sleep problems are a common issue in people with ADHD, reported in up to 50% of cases. Sleep disturbances in adults with intellectual disabilities may be labelled as 'challenging behaviour' rather than recognised as a symptom of ADHD.
The characteristic features of Down's syndrome, such as hypotonia, obesity, and craniofacial abnormalities, increase the risk of sleep-disordered breathing, including obstructive sleep apnoea (OSA). Patients with Smith-Magenis syndrome are at increased risk of circadian sleep-wake disorders, often presenting with an inverted sleep-wake cycle due to an aberrant melatonin pathway.
The role of the environment in the genesis of sleep disorders is crucial. Staffed residential homes may not be ideal for sleeping due to increased noise and lighting from staff checking on residents during the night. Other environmental factors include living with others with sleep difficulties, lack of access to outdoor activities, and reliance on support staff for simple measures like black-out blinds.
The management of sleep disorders is complicated by the heterogeneity of underlying causes and associated comorbidities. There is a lack of robust evidence regarding both non-pharmacological and pharmacological strategies for managing sleep disorders in adults with intellectual disabilities.

Sleep and mental health
Sleep is an incredibly complex process that goes beyond body resting. It is a state of involuntary activity in which the brain is relatively still and responds to internal stimuli. The exact purpose of sleep is not fully understood, but it has many functions, including neuronal plasticity, memory consolidation, immune function, growth, and mental health.
Sleep and Neurodivergence
Neurodivergent individuals often experience sleep issues, with over half of children with autism and an estimated 25% to 50% of people with ADHD experiencing sleep problems. These issues often carry over into teenage and adult years, creating challenges in falling and staying asleep. Structural differences in the brain and chemical production may be responsible for these disruptions. For example, ADHD, autism, and other forms of neurodivergence can cause delays in the circadian rhythm and changes in natural melatonin production, a critical chemical for healthy sleep.
Impact of Sleep on Overall Health
Not getting enough sleep is linked to various chronic diseases and conditions, including type 2 diabetes, heart disease, obesity, and depression. Sleep deprivation can lead to emotional disturbances, increased stress response, mood disorders, cognitive and performance deficits, and reduced quality of life.
Strategies for Improving Sleep
- Maintaining a consistent sleep schedule by going to bed and waking up at the same time every day.
- Creating a relaxing bedtime routine that includes activities such as reading or listening to calming music.
- Avoiding screen time before bed, as the blue light emitted by electronic devices can disrupt sleep.
- Engaging in physical activity during the day, especially outdoor activities, which can make it easier to fall asleep.
- Establishing a sleep routine for children, which may include a story or music, and visually presenting the routine using photos, drawings, or words.
Sleep is a critical component of physical and mental health, and addressing sleep issues is essential for improving overall well-being, especially for neurodivergent individuals who may be more susceptible to sleep disturbances. By understanding the impact of sleep on mental health and implementing strategies to improve sleep quality, individuals can enhance their overall health and daily functioning.
