I remember being at dinner with some friends a few years ago. We were reminiscing about the early infancies of our children and how we celebrated the moment when our youngsters began sleeping through the night (or somewhere close). We joined in the discussion with the enthusiasm typical of mothers speaking to other mothers who’ve “been there”, but whose travail was somewhere in the past. That is, most of us did. One of my dear friends reacted to the conversation by putting her hands over her ears and joking that she “didn’t want to hear it”. Her two children had AutismSpectrum Disorders and, into early elementary school, were not predictably sleeping through the night. While her reaction was impressively good-natured, the long-term struggle with something as basic as sleep had real-life, everyday ramifications for their family, and underneath her lightheartedness, it wasn’t a casual matter.
Practitioners and researchers who work with AutismSpectrum Disorder have increasingly taken notice of the wide-spread and serious matter of sleep disruption in ASD children, teens, and adults. Sleep problems are very common in this population, with studies indicating difficulties in this area occurring for between 50 and 83% of ASD children, often extending into adolescence. More and more, as professionals are developing intervention priorities, improving sleep is at the top of the list. Sleep difficulties can take different forms including:
The reasons for the rate of sleep disruption in this population is an on-going question for researchers, but some likely causes include:
It can be difficult, especially for new parents, to determine when a child has a problem with sleep that may require intervention, and those that fall in to the category of “typical” disruption. It may be helpful to use the following as a guideline for trying to determine whether normal variations in sleep have reached the level of a sleep disruption:
We have all experienced the effects of the lack of good sleep on our daytime functioning, but these effects may have more profound implications for children with ASD. Research has shown that ASD children with sleep problems have lowered cognitive functions (particularly with verbal skills that typically require more effort and concentration on their part), have more difficulty with social skills and increased emotional distress, increased hyperactivity, and poorer motor control. These impairments in turn make it difficult for ASD children to benefit as much as they might from the schedule of interventions that often make up their day. Sleep problems in an individual child have implications for the entire family: studies indicate that the parents of children with autism sleep less, have poorer sleep quality, and wake up earlier than parents of neurotypical children.
I want to pause for a moment to acknowledge the obvious: Parents of children with ASD want their children to sleep well and in many cases have gone to great lengths and have made personal sacrifices to accommodate, let alone address, their child’s sleep difficulties. Sleep (along with eating and toileting) is behavior that parents can not directly control by physically manipulating or exerting their will on their child. There is a significant amount of stress involved in attempting to improve sleep, and parents need to feel supported rather than judged as they begin to make changes. I will be making some suggestions about how to support better sleep in the next few paragraphs, but acknowledge that sleep difficulties are rooted in problems with neurobehavioral regulation and, as such, are often challenging to alter.
While keeping this in mind, parents should know that there is encouraging evidence to support the idea that parental efforts at improving sleep can lead to very positive outcomes. Researchers at Vanderbilt University have been studying sleep disruption in children with ASD for over a decade and have found that educating and supporting parents in understanding sleep disruption was critical to improving sleep for their children, and that most families in the study were able to make long-term improvements with parent-implemented interventions (Malow, Adkins, Reynold, Weiss, Log, Fawkes, Katz, Goldman, Madduri, Hundley, & Clemons, Parent-Based Sleep Education for Children with Autism Spectrum Disorders, Journal of Autism and Developmental Disorders, 2014 Jan 44(1): 216-228).
The first step in addressing sleep problems is to discuss the issue with your child’s primary health care professional. This is an important step because your doctor can help rule out potential medical issues or determine whether a more specialized appointment is necessary (such as a sleep specialist, ENT, or a neurologist). Your primary care provider would also be the appropriate person to see in order to discuss whether medication or a supplement such as Melatonin would be a reasonable avenue to consider. Melatonin is a naturally occurring neurochemical that assists in regulating the sleep-wake cycle. Children with Autism Spectrum Disorders have been found to have abnormal Melatonin levels, particularly at night. Over twenty clinical studies have shown a significant improvement in sleep length and sleep latency for ASD children who were given Melatonin before bedtime, even at relatively small doses (1-3 mg.). Negative side effects have been described as “minimal”, although experts note that long-term effects deserve further investigation. (Rossignol DA, Frye RE. Melatonin in Autism Spectrum Disorders, Current Issues in Clinical Pharmacology, 2014; 9(4):326-34). Medications used to treat other ASD symptoms can sometimes affect sleep regulations and sharing information about this dynamic will be important for your pediatrician or psychiatrist as they work with you to find an optimal regimen.
Regardless of the cause or nature of sleep disruption, there are environmental and behavioral mechanisms that can be put in place to support sleep. While the initial effort required to implement some of these strategies may seem overwhelming, often substantial change can be seen within a relatively short period of time (two weeks is a commonly reported time frame for seeing improved response). One of my preferred resources for sleep intervention is the “Tool Kit” offered without cost by Autism Speaks. A tool-kit is also available for teen and young-adults: (http://www.autismspeaks.org/docs/sciencedocs/atn/sleep-tool-kit.pdf). Their research-based suggestions focus on the following strategy for tackling sleep problems:
