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.

Cortical Thickness Differences in Autistic Children With and Without Intellectual Disability / Derek S. ANDREWS in Autism Research, 18-3 (March 2025)

The cortex has been widely implicated in neural processes underlying autistic behaviors as well as intellectual ability. Thus, neuroimaging features such as cortical thickness are of particular interest as a possible biomarkers of the condition. However, neuroimaging studies often fail to include autistic individuals with ID. As a result, there are few studies of cortical thickness in autistic individuals across the entire range of intellectual abilities. This study used MRI to evaluate cortical thickness in young autistic children (n?=?88, mean age 5.37?years) with a large range of intellectual ability (IQ 19?133) as well as nonautistic, nondevelopmentally delayed (referred to here as typically developing [TD]) peers (n?=?53, mean age 5.29?years). We first investigated associations between full scale IQ and cortical thickness in both autistic and TD children. Autistic children had significant negative associations (i.e., thinner cortex, higher IQ) in bilateral entorhinal cortex, right fusiform gyrus, superior, middle and inferior temporal gyri, and right temporal pole that were not present in TD children. Significantly thicker cortex was also observed in these regions for autistic children with ID (i.e., IQ???70) compared with those without. Last, given the reported correspondence between the severity of autism symptoms and intellectual ability, we compared cortical thickness associations with both IQ and ADOS Calibrated Severity Scores and found these patterns overlapped to a significant degree across the cortex.

Developmental-behavioral profiles in children with autism spectrum disorder and co-occurring gastrointestinal symptoms / Bibiana RESTREPO in Autism Research, 13-10 (October 2020)  

Public ISBD [article]  inAutism Research > 13-10 (October 2020) . - p.1778-1789 Titre : Developmental-behavioral profiles in children with autism spectrum disorder and co-occurring gastrointestinal symptoms Type de document : Texte imprimé et/ou numérique Auteurs : Bibiana RESTREPO, Auteur ; Kathleen ANGKUSTSIRI, Auteur ; Sandra L.

NORDAHL, Auteur Article en page(s) : p.1778-1789 Langues : Anglais (eng) Mots-clés : GI dysfunction  GI symptoms  autism  autism spectrum disorder  co-occurring  coexisting  comorbidities  gastrointestinal problems  repetitive behavior Index. décimale : PER Périodiques Résumé : Gastrointestinal (GI) symptoms are frequently reported in children with autism spectrum disorder (ASD). We evaluated the frequency and severity of GI symptoms in preschool-aged children with ASD compared to participants with typical development (TD). Our goal was to ascertain whether GI symptoms are associated with differences in sex or developmental and behavioral measures. Participants were between 2 and 3.5?years of age and included 255 children with ASD (184 males/71 females) and 129 age-matched TD controls (75 males/54 females). A parent interview was used to assess GI symptoms (abdominal pain, gaseousness/bloating, diarrhea, constipation, pain on stooling, vomiting, difficulty swallowing, blood in stool or in vomit). Children with GI symptoms in each diagnostic group were compared to children without GI symptoms on measures of developmental, behavioral, and adaptive functioning. GI symptoms were reported more frequently in children with ASD compared to the TD group (47.8% vs. 17.8%, respectively). Children with ASD were also more likely to experience multiple GI symptoms (30.6% vs. 5.4%). GI symptoms were equally common in males and females across both diagnostic groups. There were no statistically significant differences in developmental or adaptive measures based on presence of GI symptoms in either ASD or TD children. Co-occurring GI symptoms were, however, associated with increased self-injurious behaviors, restricted stereotyped behaviors, aggressive behaviors, sleep problems and attention problems in both ASD and TD children. In children with ASD, a higher number of GI symptoms was associated with an increase in self-injurious behaviors, somatic complaints, reduced sleep duration, and increased parasomnias. LAY SUMMARY: ASD is characterized by challenges in social communication and repetitive behaviors. But, people with autism have many other difficulties including gastrointestinal problems. Children with ASD were three times more likely to experience GI symptoms than typically developing peers. Increased GI symptoms are associated with increased problem behaviors such as sleep problems, self-injury, and body aches. Since GI symptoms are often treatable, it is important to recognize them as soon as possible. Both clinicians and parents should become more aware of the high occurrence of GI problems in autistic people.

Fear Potentiated Startle in Children With Autism Spectrum Disorder: Association With Anxiety Symptoms and Amygdala Volume / David HESSL in Autism Research, 14-3 (March 2021)  

Public ISBD [article]  inAutism Research > 14-3 (March 2021) . - p.450-463 Titre : Fear Potentiated Startle in Children With Autism Spectrum Disorder: Association With Anxiety Symptoms and Amygdala Volume Type de document : Texte imprimé et/ou numérique Auteurs : David HESSL, Auteur ; Lauren LIBERO, Auteur ; Andrea SCHNEIDER, Auteur ; Connor M. KERNS, Auteur ; Breanna WINDER-PATEL, Auteur ; Brianna HEATH, Auteur ; Joshua LEE, Auteur ; Cory COLEMAN, Auteur ; Natasha SHARMA, Auteur ; Marjorie SOLOMON, Auteur ; Christine W.

AMARAL, Auteur Article en page(s) : p.450-463 Langues : Anglais (eng) Mots-clés : Mri  anxiety  autism  autistic  fear conditioning Index. décimale : PER Périodiques Résumé : Atypical responses to fearful stimuli and the presence of various forms of anxiety are commonly seen in children with autism spectrum disorder (ASD). The fear potentiated startle paradigm (FPS), which has been studied both in relation to anxiety and as a probe for amygdala function, was carried out in 97 children aged 9-14?years including 48 (12 female) with ASD and 49 (14 female) with typical development (TD). In addition, exploratory analyses were conducted examining the association between FPS and amygdala volume as assessed with magnetic resonance imaging in a subset of the children with ASD with or without an anxiety disorder with available MRI data. While the startle latency was increased in the children with ASD, there was no group difference in FPS. FPS was not significantly associated with traditional Diagnostic and Statistical Manual (DSM) or "autism distinct" forms of anxiety. Within the autism group, FPS was negatively correlated with amygdala volume. Multiple regression analyses revealed that the association between FPS and anxiety severity was significantly moderated by the size of the amygdala, such that the association between FPS and anxiety was significantly more positive in children with larger amygdalas than smaller amygdalas. These findings highlight the heterogeneity of emotional reactivity associated with ASD and the difficulties in establishing biologically meaningful probes of altered brain function. LAY SUMMARY: Many children with autism spectrum disorder (ASD) have additional problems such as anxiety that can greatly impact their lives. How these co-occurring symptoms develop is not well understood. We studied the amygdala, a region of the brain critical for processing fear and a laboratory method called fear potentiated startle for measuring fear conditioning, in children with ASD (with and without an anxiety disorder) and typically developing children. Results showed that the connection between fear conditioning and anxiety is dependent on the size of the amygdala in children with ASD.

The prevalence and direction of change, however, are still not well understood. Nor are the characteristics of children that experience change. Symptom severity trajectories were evaluated from early to middle childhood (approximately ages 3-11) for 182 autistic children. Symptom severity change was evaluated using individual change scores and the Reliable Change Index. Fifty-one percent of participants experienced symptom severity change: 27% of children decreased in severity, 24% increased and 49% were stable. Symptom severity decreases were more common during early childhood. Severity increases occurred at both early and middle childhood but increase in social affect severity was especially prominent during middle childhood. Most children experienced significant change during only one period and remained stable during the other. Girls decreased more and increased less in symptom severity than boys. Children that increased in severity decreased in adaptive functioning across childhood. Exploratory analyses indicated that a decrease in severity was associated with higher parental education level and older parental age at the time of the child's birth. Conversely, increase in autism severity was associated with lower parental education level and younger parental age at the child's birth. These findings extend recent observations that symptom severity change is more likely than previously appreciated. An understanding of the role of both biological and sociodemographic factors in determining a child's symptom trajectory may factor into future decisions on allocation and type of interventions distributed to young autistic children. LAY SUMMARY: We studied whether a child's autism severity changed from initial diagnosis until middle childhood (ages 3-11). We found that 27% of the children decreased in severity, 24% increased and the rest stayed the same. Symptom severity decreases were more common during early childhood while severity increases were more prominent during middle childhood. We also found that girls were more likely to decrease than boys. Whether a child decreased or increased is related, in part, to parental characteristics.
