We evaluated this relationship in 75 autistic children from 6 to 11 years old. Autism symptom severity change was evaluated for total autism symptoms using the autism diagnostic observation schedule calibrated severity score, as well as social-communication symptoms calibrated severity score, and restricted/repetitive behaviors calibrated severity score. Children were grouped based on their symptom severity change patterns. Mental health symptoms (attention-deficit hyperactivity disorder, anxiety, disruptive behavior problems) were assessed via parental interview and questionnaire and compared across the groups. Co-occurring mental health symptoms were more strongly associated with change in social-communication symptom or restricted/repetitive behavior severity than with total autism symptom severity. Two relevant groups were identified. The social-communication symptom-increasing-severity-group (21.3%) had elevated and increasing levels of anxiety, attention-deficit hyperactivity disorder, and disruptive behavior problems compared with children with stable social-communication symptom severity. The restricted/repetitive behavior-decreasing-severity-group (22.7%) had elevated and increasing levels of anxiety; 94% of these children met criteria for an anxiety disorder. Autism symptom severity change during middle childhood is associated with co-occurring mental health symptoms. Children that increase in social-communication symptom severity are also likely to demonstrate greater psychopathology, while decreases in restricted/repetitive behavior severity are associated with higher levels of anxiety. Lay abstract For many autistic children, the severity of their autism symptoms changes during middle childhood. We studied whether these changes are associated with the emergence of other mental health challenges such as anxiety and attention-deficit hyperactivity disorder. Children who had increased social-communication challenges had more anxiety and attention-deficit hyperactivity disorder symptoms and disruptive behavior problems than other children. Children who decreased their restricted and repetitive behaviors, on the contrary, had more anxiety. We discuss why these changes in autism symptoms may lead to increases in other mental health concerns.

Hypothalamic volume is associated with dysregulated sleep in autistic and non-autistic young children / Burt HATCH in Autism, 29-11 (November 2025)

This study tested associations between subcortical regions implicated in sleep processes and measures of dysregulated sleep initiation/maintenance in autistic and non-autistic 2- to 4-year-olds. The role of co-occurring externalizing and internalizing symptoms in these associations was also evaluated. Participants included 203 autistic (131 males, 72 females) and 92 non-autistic (49 males, 43 females) 2- to 4-year-olds who completed magnetic resonance imaging. A subscale of items from the Children’s Sleep Habits Questionnaire, previously shown to be reliable across both autistic and non-autistic children, was used to measure dysregulated sleep initiation/maintenance. Externalizing and internalizing symptoms were evaluated using the Child Behavior Checklist–Preschool. Associations between volumes for nine subcortical structures known to be implicated in sleep were separately modeled. Mediation analyses explored whether such associations could be accounted for by externalizing or internalizing symptoms. Smaller right hypothalamus volume was associated with dysregulated sleep initiation/maintenance in both autistic and non-autistic children. Externalizing (but not internalizing) problems partially mediated this association. Findings implicate the right hypothalamus in sleep initiation and maintenance issues for both autistic and non-autistic young children, supporting prior evidence of its central role in sleep regulation.Lay Abstract Difficulty initiating or maintaining sleep is common among autistic individuals and often goes alongside difficulties regulating emotions and behavior during the day. Although there is a body of research suggesting that subcortical brain regions, including a brain region known as the hypothalamus, play important roles regulating sleep, few studies have examined whether this extends to young autistic children. Using data from a sample of 203 autistic (131 males, 72 females) and 92 non-autistic (49 males, 43 females) 2- to 4-year-olds, we examined whether size of subcortical brain regions implicated in sleep processes is associated with difficulties initiating and/or maintaining sleep. In addition, we examined whether daytime behaviors and emotions were also implicated in these associations. We found that smaller right hypothalamus volume was associated with dysregulated sleep initiation/maintenance in both autistic and non-autistic children. This relationship remained evident even after accounting for externalizing behaviors and emotions like anger that were also associated with both the hypothalamus and dysregulated sleep initiation/maintenance. The strength of association between right hypothalamus volumes and dysregulated sleep initiation/maintenance was similar for autistic and non-autistic children. These findings suggest that for both young autistic and non-autistic children, the hypothalamus plays unique roles in regulating both sleep and externalizing behaviors. For managing sleep initiation and maintenance difficulties in clinical practice, the findings underscore the importance of considering environmental (e.g. not having a regular bedtime routine) and neurobiological factors, for both autistic and non-autistic young children.

This study sought to determine the longitudinal trajectory of gastrointestinal symptoms without a medical etiology in children with autism compared to similar aged participants with typical development. A total of 475 children enrolled in this longitudinal study (322 autism spectrum disorder and 153 typical development groups) were evaluated at up to three time points between 2 and 12 years of age. Nine common gastrointestinal symptoms and formal medical gastrointestinal diagnosis were assessed using a physician-administered parent interview. A rigorous symptom classification was performed by physicians via clinical consensus. The frequency and persistence of gastrointestinal symptoms across childhood were compared between groups. Associations between gastrointestinal symptoms and measures of internalizing and externalizing behaviors, sleep problems, sensory problems, restricted and repetitive behaviors, and social communication were also evaluated. Children with autism presented with more gastrointestinal symptoms at each time point, and they were also more likely to experience multiple and persistent gastrointestinal symptoms. The presence and number of gastrointestinal symptoms were associated with greater impairment in internalizing behaviors, sleep, communication, sensory processing, and repetitive behaviors. Participants in the autism spectrum disorder group reported more gastrointestinal symptoms without known etiology throughout childhood in this longitudinal well-characterized sample.Lay Abstract Children with autism have been found to experience more medical issues including gastrointestinal symptoms. In this study, participants in the autism group were more likely to experience gastrointestinal symptoms than their typically developing peers. They were also more likely to experience multiple gastrointestinal symptoms at the same time and more likely to have persistent gastrointestinal symptoms throughout their childhood. Increased gastrointestinal symptoms were associated with more challenges with sleep, communication, sensory processing, and repetitive behaviors. Clinicians and parents should become more aware of the high occurrence of gastrointestinal problems in children with autism. If identified, these symptoms are often treatable which may improve their well-being.

Patterns of sensory processing in young children with autism: Differences in autism characteristics, adaptive skills, and attentional problems / Girija KADLASKAR in Autism, 27-3 (April 2023)

However, our understanding of sensory profiles in this population has been complicated due to the heterogeneous presentation of sensory symptoms. We addressed this by using latent profile analysis, allowing for the identification of more homogeneous sensory classes in a large cohort (n=211 (52 females), 2-4 years) of autistic children using subscale scores from the Short Sensory Profile. Based on the patterns of both severity and sensory modality, four classes emerged: Moderate/Mixed (35.5%), Severe/Mixed (8.5%), Moderate/Broad (14.6%), and Low/Mixed (41.1%). While a subset of children displayed normative sensory-related behaviors, the majority showed a combination of both hypo- and hyper-reactivity across various sensory modalities. Subsequent analyses showed that the class characterized by Severe/Mixed sensory differences exhibited greater problems in a variety of areas such as social and adaptive skills and attention-deficit/hyperactivity disorder symptoms, whereas the Low/Mixed class showed overall fewer problems. Identification of homogeneous classes may be useful for neurophysiological/imaging studies focusing on studying underlying mechanisms linked with specific sensory patterns. These findings may help clinicians identify children with particular sensory profiles that might relate to other social, adaptive, or behavioral domains with potential implications for intervention.Lay abstractResearch has found differences in responding to various sensory stimuli among autistic individuals, which are associated with social and adaptive skills. However, our understanding of sensory profiles in autism has been complicated due to the variable presentation of sensory symptoms. One way to better understand variability in sensory symptoms is to use advanced statistical approaches, such as latent profile analysis, that allow for the identification of more similar sensory classes in otherwise variable groups. We used the Short Sensory Profile to identify homogeneous classes of sensory reactivity in autistic children based on both severity and modality and examined whether sensory classes differed in terms of autism characteristics, adaptive skills, and attention-deficit/hyperactivity disorder symptoms. Based on the pattern of both severity and modality, four sensory classes emerged and were named Moderate/Mixed (35.5%; probable-to-definite differences in all modalities except in movement sensitivity and low energy/weakness), Severe/Mixed (8.5%; definite sensory differences in all modalities except in low energy/weakness), Moderate/Broad (14.6%; probable-to-definite differences in all modalities), and Low/Mixed (41.1%; typical scores in most modalities with probable differences in taste/smell sensitivity, under-responsive/seeks sensation, and auditory filtering). The Severe/Mixed class exhibited greater problems in a variety of areas such as social, adaptive, and attention-deficit/hyperactivity disorder symptoms, whereas the Low/Mixed class showed overall fewer problems. This may provide insight for clinicians and researchers aiming to understand whether autistic children who exhibit distinct sensory patterns are more or less likely to also experience social, adaptive, and/or attention/behavior-related difficulties.
