Child ADHD & Insomnia

Insomnia & ADHD
Sleep disorders are one of the most common comorbidities reported in individuals with ADHD, affecting approximately 70% of children and adolescents. In 45% of cases, parents reported higher moderate or severe sleep problems when compared with typically developing children. Sleep problems are persistent and reported by up to 80% of adults with ADHD.
​
Most of the sleep complaints in children and adolescents with ADHD are not only difficulty in falling asleep (sleep onset) but also maintaining sleep due to irregular midsleep awakenings. Both contribute to a shortened night sleep duration.
​
People affected by ADHD already have numerous difficulties engaging in social interaction. Lack of sleep can make this even worse by causing daytime impairments such as increased hyperactivity and irritability, greater anxiety and higher sensory sensitivity. If left untreated, especially in children under 6 years of age, insomnia has the potential to exacerbate the core symptoms of ADHD.
​
Sleep disturbances may exacerbate the symptoms of ADHD - especially over the next day. In children with ADHD, sleep restriction deteriorated from subclinical levels to the clinical range of inattention. Therefore, the therapy of sleep disorders, in particular improving sleep duration. is associated with improved functioning in both children with ADHD and their whole family.

Etiology of insomnia in children with ASD​​

Neurobiological Factors
​
Altered dopamine activityâ€, ‬disrupted circadian rhythmâ€, ‬changes in brain regions controlling sleepâ€.

Behavioral Factorsâ€
Inconsistent bedtime routinesâ€, ‬difficulty with time managementâ€, ‬trouble self-regulatingâ€.

Medication Effects ‬â€
Some ADHD medicinesâ€, ‬especially stimulantsâ€, ‬can delay or disturb sleepâ€.
​

Melatonin Imbalance ‬â€
‬Many children with ADHD have irregular or delayed melatonin secretion patternsâ€.
Insomnia treatment goals
When treating insomnia in children with ADHD we should evaluate the child sleep according to the following DSM5 treatment goals:
-
Total sleep time (TST) within the acceptable range recommended by the national sleep foundation (NSF)
-
Sleep onset latency (SOL) < 30 minutes
-
Longest (uninterrupted) sleep episode (LSE)>6 hours
​​
When evaluating treatment success, a clinician should also evaluate the improvement in the child’s behavior and parents’ satisfaction from child sleep.
Sleep duration recommendation by the National Sleep Foundation:

Current insomnia treatment in children with ADHD
Current practices recommend sleep hygiene interventions including establishing bedtime routines as first-line treatment for pediatric insomnia in ADHDâ€. ‬Pharmacotherapy is often provided when sleep hygiene intervention is insufficientâ€.‬
Research on the management of sleep disorders in individuals with ADHD is limitedâ€. ‬To dateâ€, ‬evidence supports behavioral interventions and melatoninâ€- ‬especially prolonged-release melatonin to improve both sleep initiation and maintenanceâ€.‬‬​

Why prolonged-release matters
-
Prolonged-release melatoninâ€: ‬maintains melatonin levels through the nightâ€, ‬improves sleepâ€, ‬and restores the daily sleep-wake cycleâ€.‬
​​
-
Immediate-release melatoninâ€: ‬helps children fall asleep but wears off quicklyâ€, ‬leading to early awakeningsâ€. ‬unlicensed melatonin†‬preparations or food supplements are also usedâ€, ‬despite considerable concerns over the qualityâ€, ‬efficacy and potential safety hazardsâ€.‬
The USA National Sleep Foundation summarized the profile of the ideal pharmacological therapy for pediatric insomniaâ€. ‬One such therapy should be able to positively affect sleep parametersâ€, ‬be easy to administerâ€, ‬be dose adjustableâ€, ‬have a good safety profileâ€, ‬offer sustainable benefits and will not impair sleep architectureâ€. ‬

Slenyto® is the only prolonged-release melatonin (PRM) formulation designed to mimic the endogenous profile by releasing melatonin throughout the night helping to improve both sleep initiation and sleep maintenance without early awakenings.
​
Slenyto® is approved by EMA and other regulatory authorities for treating insomnia in children and adolescents with ASD, neurogenetic disorders and ADHD.
