A protocol for measuring sleep at home in children with autism using EEG headbands.
Article in Research square, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Autism spectrum disorders (ASD) are a group of neurodevelopmental disorders characterized by social and communication challenges and the presence of restricted interests, repetitive behaviors, and atypical sensory processing. Sleep disturbances are prevalent in ASD and worsen daytime functioning, yet their neural bases remain poorly understood. We hypothesize that thalamocortical circuit dysfunction contributes to poor sleep in ASD. To test this hypothesis, we employ sleep EEG to determine whether sleep spindles, biomarkers of thalamocortical circuit function, are reduced in ASD and correlate with sleep quality. Since laboratory-based overnight sleep studies are costly, burdensome, and particularly problematic for individuals with ASD, we use wearable EEG headbands to record sleep in the home. This paper describes the methodology of our ongoing study of sleep in adolescents with ASD, including those with profound autism. An optional desensitization protocol helps participants gradually acclimate to the headband, promoting inclusion of individuals with sensory sensitivities and greater support needs. Methods: We plan to enroll 80 adolescents with ASD and 80 of their typically developing peers. Participants and their families are trained remotely to use a wearable EEG headband. They also complete assessments and questionnaires. Participants who need time to acclimate follow a personalized 2-week desensitization protocol with a practice headband. Sleep is monitored at home for 3 consecutive nights, the first of which is for adaptation to sleeping with the headband. Sleep data quality is checked daily and remote technical support is provided as needed. Discussion: At-home sleep monitoring enables larger samples that are needed to characterize the neural underpinnings of sleep disturbances across the autism spectrum. The personalized desensitization protocol promotes inclusivity by accommodating individuals often excluded from research due to sensory or behavioral challenges. These methods are adaptable for other conditions and research goals beyond ASD, such as longitudinal studies across development or characterizing sleep in other neurodevelopmental disorders. Desensitization protocols may also increase the tolerability of diagnostic lab-based sleep studies and other medical procedures, improving both patient experience and quality of care.
