Sleep problems focus of new study on Kiwi kids with autism

New research will look at developing effective treatments for sleep problems that affect the growing number of New Zealand children and young people with autism spectrum disorder (ASD).

University of Canterbury up-and-coming researcher Dr Laurie McLay has received an emerging researcher first grant from the Health Research Council of New Zealand (HRC) to investigate the use of functional behavioural assessment1 to develop individualised, comprehensive sleep treatments for children with ASD. She will be working with a team of psychologists including Associate Professor Karyn France and Professor Neville Blampied, both from the University of Canterbury.

Sleep disruptions such as delayed sleep onset and frequent and prolonged night-time awakenings, can have an enormous impact on how children function during the day and within their families. Such sleep problems are associated with poorer physical and mental health and wellbeing (e.g., obesity, diabetes, mood disorders, and substance abuse), quality of life, cognitive functioning, learning, and academic performance.

Dr McLay says that up to 83 per cent of children with ASD experience sleep disturbances, and that these are unlikely to abate over time in these children without effective treatment.

Although these sleep problems are complex in origin, she says evidence suggests there is a learned component that requires behavioural solutions.

“There are poorly understood biochemical differences in children with autism, such as irregular melatonin production and secretion, however, pharmacological strategies like melatonin and sedative medications only offer partial solutions. There is a large, treatable behavioural component to the sleep problem that becomes entwined with the parental behaviours that can unintentionally exacerbate it,” says Dr McLay.

For this HRC-funded study, Dr McLay and her team will recruit children throughout New Zealand aged between three and 18 who have been formally diagnosed with ASD and whose parents have reported sleep disturbances.

HRC Chief Executive Professor Kath McPherson says the results from this study could significantly improve the effectiveness of clinical treatments for sleep disturbances in children with ASD, but also have further general benefits “given that sleep problems in children with ASD have a major impact on their daytime behaviour, the severity of their ASD symptoms, and the wellbeing of their parents and families”.

Dr McLay is one of 13 researchers to receive emerging researcher first grants valued at a combined total of $3.03 million in the HRC’s 2017 funding round, up from $1.45 million in 2016.

“By targeting support to New Zealand’s most promising emerging researchers in priority health areas such as our young people, we’re helping to ensure that the research workforce can meet the needs of the healthcare system and our unique population, both now and into the future,” says Professor McPherson.

1 Functional behavioural assessment is a broad term used to describe a number of different methods that allow researchers and practitioners to identify the reason behind a specific behaviour.
