Composite Sleep Problems Observed Across Smith-Magenis Syndrome, MBD5-Associated Neurodevelopmental Disorder, Pitt-Hopkins Syndrome, and ASD.
Sleep trouble looks different in each rare syndrome—check for night wakings and scary dreams especially in SMS and MBD5.
01Research in Context
What this study did
Parents filled out a sleep survey. They had kids with Smith-Magenis, MBD5, Pitt-Hopkins, or plain ASD.
The team looked at which sleep problems showed up most in each group.
What they found
SMS and MBD5 kids had the roughest nights. They woke often and had scary dreams.
Pitt-Hopkins kids slept better than those two groups. ASD landed in the middle.
Each syndrome had its own "fingerprint" of night trouble.
How this fits with other research
Hodge et al. (2014) already showed ASD kids sleep worse than typical peers. The new data say even within ASD, the story changes once you pull in rare genes.
Allik et al. (2008) tracked ASD kids over time and saw little improvement. Anusha’s snapshot now warns that SMS and MAND nights are worse than classic ASD, so don’t lump them.
Berenguer et al. (2024) added ADHD to the mix and linked bad sleep to poor talking. Anusha didn’t test skills, but both papers shout: screen sleep in every neurodevelopmental case.
Why it matters
If you serve a child with SMS or MBD5, expect parasomnias and plan for night checks. Pitt-Hopkins families may need lighter supports. Tailor bedtime plans to the gene group, not just the ASD label.

03Original abstract
Caregivers of preschool and elementary school age children with Smith-Magenis syndrome (SMS), MBD5-associated neurodevelopmental disorder (MAND), and Pitt-Hopkins syndrome (PTHS) were surveyed to assess sleep disturbance and to identify disorder-specific sleep problems. Because of overlapping features of these rare genetic neurodevelopmental syndromes, data were compared to reports of sleep disturbance in children with autism spectrum disorder (ASD). While similarities were observed with ASD, specific concerns between disorders differed, including mean nighttime sleep duration, daytime sleepiness, night wakings, parasomnias, restless sleep, and bedwetting. Overall, sleep disturbance in PTHS is significant but less severe than in SMS and MAND. The complexity of these conditions and the challenges of underlying sleep disturbance indicate the need for more support, education, and ongoing management of sleep for these individuals.
