Description : Check out this medical PowerPoint presentation titled "Sleep Issues and Developmental Disabilities" by Michael Mak, MD, FRCPC.
This medical PowerPoint presentation discusses how sleep disturbances can have significant negative impacts on individuals with developmental disabilities.
Sleep issues are common among individuals with developmental disabilities. Some of the most common developmental disabilities associated with sleep disturbances include autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), Down syndrome, and cerebral palsy.
Individuals with ASD often have difficulty falling and staying asleep, as well as disrupted sleep patterns. This may be due to sensory processing difficulties, such as hypersensitivity to noise or light, which can make it difficult to fall asleep. Additionally, individuals with ASD may have anxiety or obsessive-compulsive behaviors that can interfere with sleep.
ADHD is also associated with sleep disturbances, including difficulty falling and staying asleep, and restless sleep. Children with ADHD may have trouble settling down at night due to hyperactivity or impulsivity, and they may have difficulty waking up in the morning.
Individuals with Down syndrome often have sleep apnea, which can cause snoring, pauses in breathing during sleep, and disrupted sleep. This is due to the characteristic facial features and small airways that are common in individuals with Down syndrome.
Cerebral palsy can also be associated with sleep disturbances, such as difficulty falling asleep and staying asleep, as well as frequent waking during the night. This may be due to physical discomfort or pain, spasticity or stiffness in the muscles, or other medical issues.
Sleep disturbances can have significant negative impacts on individuals with developmental disabilities, including impaired cognitive functioning, behavior problems, and poor quality of life. Therefore, it is important to identify and address sleep issues in individuals with developmental disabilities in order to improve their overall well-being.

Normal Sleep Architecture and Assessment Tools
Slide 6-

Sleep Architecture Two types of sleep: non-rapid eye-movement (NREM) sleep and rapid eye-movement (REM) sleep. NREM sleep is divided into stages 1, 2, and 3 (SWS), representing a continuum of relative depth. REM sleep is dream sleep. Each has unique characteristics including variations in brain wave patterns, eye movements, and muscle tone.

Slide 8-

REM vs NREM Sleep NREM and REM sleep alternate cyclically during sleep periods. The function of alternations between these two types of sleep is not yet understood, but irregular cycling and/or absent sleep stages are associated with sleep disorders. Example: an abrupt shift from deep sleep to light sleep and wakefulness may cause night terrors.
Slide 9-

NREM to REM Cycling Normal sleep begins with a short period of NREM stage 1 progressing through stage 2, followed by stages 3 and finally to REM. REM will cycle back to NREM sleep throughout the night. NREM sleep constitutes about 75 to 80 percent of total time spent in sleep, and REM sleep constitutes the remaining 20 to 25 percent. The average length of the first NREM-REM sleep cycle is 90 minutes. The second, and later, cycles are longer lasting (up to 120 minutes).
Slide 10-

NREM to REM Cycling SWS is seen in the first third of the night. As the sleep episode progresses, stage 2 begins to account for the majority of NREM sleep, and SWS may sometimes altogether disappear. REM sleep increases as the night progresses and is longest in the last third of the sleep episode.

Sleep Assessment Tools Sleep Diary Sleep History Physical Examination Actigraphy Polysomnography
Slide 13-

Sleep Diary
Slide 14-

Sleep History “Do you have any concerns regarding your child’s sleep?” “Does your child take more than 30 minutes to fall asleep at bedtime?” “Once asleep, does he stay asleep?” “Does your child seem excessively sleepy during daytime? “Have you heard your child snore or stop breathing during the night?”
Slide 15-

Actigraphy Worn on non-dominant hand Cheaper and less cumbersome than PSG Likely higher compliance
Slide 16-

Normal
Slide 17-

Polysomnography
Slide 18-

Polysomnography Measurements Electroencephalogram (EEG) – distinguishes between wakefulness and various sleep stages. Electrooculogram (EOG) – monitors eye movements. Electromyogram (EMG) – measures muscle tone on chin and limbs. ECG, airflow, video-recording, sound, effort of respiration, oxygen saturation, body positioning.
Slide 19-

Polysomnography Gold standard assessment tool for sleep disorders Not well tolerated by all Home testing an option
Slide 20-

Implication of Sleep Disturbances Sleep disturbances are a common problem in childhood – 25% in preschool and school-aged children Problems not only with children, but affects families. Increased parental stress, depression, poor marital relationships, and even child abuse
Slide 21-

Epidemiology in DD Population Sleep problems occur in up to 89% of ASD children, 86% of ID children, and 65% of children with Down Syndrome. Sleep disturbances likely associated with behavioural and psychological problems in developmental disability population.
Slide 22-

Summary Sleep divided into NREM and REM sleep. Evaluated by subjective and objective means. Sleep complaints common in young children. Even more common in developmental disabilities.
Slide 23-

Autism Spectrum Disorders
Slide 24-

ASD and Sleep Disturbances Insufficient sleep = worsening of core ASD symptoms Increased stereotypic behaviours, social, communication and cognitive difficulties Increased self-injury, non-compliance, irritability, tantrums and aggression Relationship of cognitive impairment and severity of sleep problems is mixed
Slide 25-

ASD and Sleep Disturbances Appear to persist through lifetime. Most studies focused on high functioning ASD (greater communication and cooperation with PSG and actigraphy).
Slide 26-

ASD and Sleep Problems Mixed phenotype = NO ONE TYPICAL SLEEP PROBLEM Sleep problems often go untreated.
Slide 27-

Pathophysiology Disturbed reception to circadian rhythm entrainment - light, meal timing, social contacts. Disrupted melatonin secretion. Clock gene abnormalities. Comorbidities leading to sleep disruption: GI symptoms; epilepsy; anxiety, ADHD. Medications: SSRIs, antipsychotics.
Slide 28-

Polysomnographic Findings Decreased REM sleep and TST Increased leg movements, SWS, and REM sleep latency Higher loss of REM atonia
Slide 29-

ASD - Insomnia Prolonged sleep onset latency Increased wake after sleep onset Early morning awakenings May translate to increased bedtime resistance and excessive daytime sleepiness
Slide 30-

Non-Pharmacological Treatments Behavioural Therapy Parents overwhelmingly prefer non-medication treatments
Slide 31-

Non-Pharmacological Treatments Sleep hygiene Setting appropriate bedtime and set routine Minimizing TV/LCD/LED exposure Reducing emotional and behavioural stimulation at night
Slide 32-

Non-Pharmacological Treatments Elimination of association between sleep and prerequisite conditions (e.g. bottle of milk, co-sleeping, being on the couch). Structured behavioural program improved: pre-sleep disturbances, falling sleep alone, night waking and co-sleeping.
Slide 33-

Non-Pharmacological Treatments Bright light therapy AM exposure = advance sleep onset time PM exposure = delay sleep onset time
Slide 34-

Melatonin Endogenous hormone secreted by the pineal gland Nocturnal secretion beginning at nightfall, peaking at 0300AM Secretion is suppressed by light (suprachiasmatic nuclei of hypothalamus) Major role: regulation of sleep (timing of sleepiness and circadian rhythm control)
Slide 35-

Melatonin Sleep problems occur when melatonin secretion is disturbed. O’Hare et al; Kulman et al: low serum melatonin in autistic children Abnormally elevated night time melatonin levels in ASD - Malfunctioning melatonin function?
Slide 36-

Melatonin 0.3 – 3mg Timing subject to debate Shortens sleep onset latency Increases total sleep time Does not affect midsleep awakenings ?Safe Unregulated food product
Slide 37-

Clonidine 0.05 – 1mg Shortens sleep onset latency Decreases midsleep awakenings Caution re: rebound hypertension; in cardiac and depressed populations
Slide 38-

Other Medications Only in specific situations Sedating antipsychotics (olanzapine, quetiapine, risperidone) at bedtime in those with other indications Trazodone (beware of priapism) ?zolpidem/zopiclone
Slide 39-

Other Medications Not recommended Benzodiazepines - higher chance of paradoxical effect, cognitive impairment, limited by tolerance Chloral hydrate Diphenhydramine (Benadryl), hydroxyzine
Slide 40-

ASD - Parasomnias Abnormal behaviours in sleep Night Terrors Confusional Arousals
Slide 41-

ASD - Parasomnias 54% in children with ASD Treatment Time Last resort: clonazepam at bedtime (Caution re: paradoxical agitation)
Slide 42-

ASD – Circadian Rhythm Disorders Delayed Sleep Phase - associated with severe ASD. Irregular Sleep Wake Cycle - polyphasic sleep; early decrease in physiologic total sleep time. Advanced Sleep Phase - rare
Slide 43-

ASD – Circadian Rhythm Disorders Treatments Melatonin 0.3 – 3mg Bright light therapy Behavioural approaches – avoiding blue light; sound proofing
Slide 44-

Future Research Ares Low functioning ASD Longitudinal studies - ?Sleep improves with chronological vs. developmental age
Slide 45-

Trisomy 21: Down’s Syndrome
Slide 46-

Myriad of Sleep Disturbances Bedtime resistance Increased parasomnias Excessive daytime sleepiness Increased sleep anxiety (improving with age) Midsleep awakenings (improving with age) Long sleep onset latency (improving with age)

Intellectual Disability
Slide 57-

ID 39% of adults with severe intellectual disabilities have insomnia Melatonin shown to decrease SOL and WASO Very few of these receive CBT-i and those that do have mixed results (studies are confounded by use of melatonin)
Slide 58-

ID 34.6% of ID adults were obese (BMI > 30) vs. 20.6% from general population. 28.9% of ID adults were overweight (BMI 25 – 29.9) vs. 34.1% from general population. May exhibit disturbed circadian rhythms (esp. moderate to severe ID individuals) Obese patients more likely to have sleep disordered breathing and/or sleep-related hypoventilation
Slide 59-

Summary ID associated with insomnia Melatonin best studied treatment Higher rates of obesity = need for greater apnea screening
