Getting enough sleep is widely considered crucial to our well-being. However, for some individuals with Autism, getting enough quality sleep is not as easy as it sounds.<\/span> Autism Spectrum Disorder (ASD) is a developmental disorder that widely affects the U.S. population, as 1 in 36 children aged eight has been diagnosed with autism (CDC, 2023). The kind and severity of the symptoms that individuals with ASD may exhibit can vary along the ASD spectrum.\u00a0 Sleeping, in particular, is a common challenge for those with ASD, as many suffer from problems related to the REM (Rapid Eye Movement) sleep phase, a phase critical for memory consolidation (Devnani & Hedge, 2015). This can quickly become a vicious cycle for some, as lack of sleep can increase the severity of other Autism-related symptoms but also affect both the individual and the quality of life of their family or caretakers.\u00a0<\/span><\/p>\n

To investigate possible treatments, a recent study by Malow et al.<\/span> focuses on the pharmacological approach of using melatonin to treat sleep disorders. Melatonin is a hormone produced by the body\u2019s pineal gland to regulate circadian rhythm, allowing the body to relax according to the appropriate light-darkness cycles of the day. This study uses a small, long-release tablet (PedPRM) used to mimic endogenous melatonin secretion. It focused mainly on a younger population, from children to adolescents, who met two criteria. The first was that they had confirmed diagnoses of either Autism or Smith-Magenis syndrome and had also experienced sleep abnormalities. Smith-Magenis syndrome is also a developmental disorder that involves symptoms similar to those of ASD, affecting behavior, cognition, and sleep. They also had to have not previously seen improvements when using sleep hygiene treatments to be included in the study, such as establishing a strict bedtime routine and taking steps to provide a calm and comfortable sleep environment (CHOC, 2023).<\/span><\/p>\n

\"\"<\/p>\n

With the study sample set, the study wa<\/span>s conducted over 108 weeks and divided into four phases (Graph I). Thro<\/span>ughout the four phases, participants\u2019 caregivers would document sleep quality and total sleep time in a sleep and nap diary to record the efficacy of treatment. The study participants started the first stage with a 2-week period in which they were given placebos. If participants showed improvement while receiving a placebo, they would be removed from the study to reduce the possibility of external factors affecting the results (Scott et al., 2021). After clearing Phase 1, participants entered the second phase, which consisted of a double-blinded 13-week period in which they were randomly placed into either a placebo or treatment group (PedPRM). After this, Phase 3 comprised a longer 91-week open-label period in which both groups were combined. For the final phase of the study, participants were placed again in a 2-week single-blind placebo period to ensure that the drug had been completely removed from the participants with no adverse effects after stopping treatment.<\/p>\n

\"\"<\/p>\n

Upon concluding the experimental period, the results to be considered for this study could be divided into three groups: participants’ sleep quality, caregivers’ well-being, and the participants’ growth development. With this data, the researchers found a significant<\/span><\/p>\n

\u00a0decrease in sleep disturbance (Graph II-A) and an increase in caregiver satisfaction (II-B) and quality of life (II-C). These were most pronounced during the first half of the treatment. In the latter half of treatment, sleep disturbance continued to decrease but at a slower pace than the initial treatment phase. Fortunately, there were no reported deaths, and most adverse reactions included daytime fatigue and mood swings. However, the severity and extent of these were not detailed in the results of the study and offer the potential to be analyzed further.\u00a0\u00a0<\/span><\/p>\n

The study shows compelling initial evidence that PedPRM is an effective treatment for sleep disorders in individuals with ASD. However, as noted by the researchers, it also shows that constant active treatment is required as most sleep quality improvements are removed upon halting treatment. Since medications for children are generally more strictly controlled, PedPRM consistently demonstrates a possibility for effective pediatric treatment, even if for long-term medication. In particular, these findings are essential as it has been found that rapid-release melatonin is not helpful with maintaining sleep a couple of hours after administration, and it had long been considered a challenge to find small, swallowable prolonged-release tablets for children (Fliesler, 2022). As sleep interruption is something that mainly affects those with neurodevelopmental disorders, this is a significant step towards adequate treatment. However, it is essential to note that this pharmacological alternative should only be considered if behavioral interventions and sleep hygiene modifications have been attempted but have been found unsuccessful.\u00a0<\/span><\/p>\n
