Many people with ASD report problems with sleep, but most ASD sleep research to date has focused on children and adolescents, with only a few studies involving adults with ASD. We also know very little about which aspects of sleep are problematic; is it difficulties with going to sleep (sleep onset latency), staying asleep (total sleep time), frequent waking during the night (wake after sleep onset), or less total sleep. There is also very little research into how daytime functioning is affected in adults with ASD who sleep poorly. One of our students, Emma Baker, has therefore decided to study sleep problems and how they are related to daytime functioning in adults with ASD. Emma is studying for her PhD under the supervision of Associate Professor Amanda Richdale who is one of the international experts on sleep problems associated with ASD.
