    • An important objective for researchers and clinicians is to gain a better understanding of the factors that underlie autism spectrum disorders (ASDs). It is possible that investigating objective and quantitative behavioral phenotypes and their relationship to clinical characteristics, such as autistic traits and other emotional/behavioral problems, might facilitate this process. Given this, in the current study we examined the link between locomotor dynamics and clinical characteristics, including autistic traits and emotional/behavioral problems, in children with ASD (n = 14) and typically developing (TD) children (n = 13). A watch-type actigraph was used to continuously measure locomotor activity which was assessed in terms of mean activity levels and the skewness of activity. Parents assessed quantitative autistic traits using the Japanese version of the Social Responsiveness Scale (SRS) and emotional and behavioral problems using the Japanese version of the Strengths and Difficulties Questionnaire (SDQ). Results showed that among all children, all-day activity was more negatively skewed, suggesting sporadic large all-day “troughs” in activity and was significantly correlated with the SRS social awareness subscale score (ρ = −0.446, p = 0.038). In addition, the more negatively skewed daytime locomotor activity was associated with the SDQ Hyperactivity Inattention subscale score (ρ = −0.493, p = 0.020). The results of this study indicate that investigating locomotor dynamics may provide one way to increase understanding of the neurophysiological mechanisms underlying the clinical characteristics of ASD.

  • Attention-deficit/hyperactivity disorder and physical multimorbidity : A population-based study
  • 2017
  • Ingår i: European psychiatry. - : Elsevier. - 0924-9338 .- 1778-3585. ; 45, s. 227-234

    • Background: There has been little research on the association of attention-deficit/hyperactivity disorder (ADHD) with co-occurring physical diseases. The aim of this study was to examine the association between possible ADHD and physical multimorbidity (i.e. >= 2 physical diseases) among adults in the English general population.Methods: Data were analyzed from 7274 individuals aged >= 18 years that came from the Adult Psychiatric Morbidity Survey 2007. ADHD symptoms were assessed with the Adult Self-Report Scale (ASRS) Screener. Information was also obtained on 20 self-reported doctor/other health professional diagnosed physical health conditions present in the past 12 months. Multivariable logistic regression and mediation analyses were conducted to assess the associations.Results: There was a monotonic relation between the number of physical diseases and possible ADHD (ASRS score >= 14). Compared to those with no diseases, individuals with >= 5 diseases had over 3 times higher odds for possible ADHD (odds ratio [OR]: 3.30, 95% confidence interval [CI]: 2.48-4.37). This association was observed in all age groups. Stressful life events (% mediated 10.3-24.3%), disordered eating (6.8%), depression (12.8%), and anxiety (24.8%) were significant mediators in the association between possible ADHD and physical multimorbidity.Conclusion: Adults that screen positive for ADHD are at an increased risk for multimorbidity and several factors are important in this association. As many adults with ADHD remain undiagnosed, the results of this study highlight the importance of detecting adult ADHD as it may confer an increased risk for poorer health outcomes, including physical multimorbidity.

  • Brief Report : Best Discriminators for Identifying Children with Autism Spectrum Disorder at an 18-Month Health Check-Up in Japan
  • 2015
  • Ingår i: Journal of autism and developmental disorders. - : Springer. - 0162-3257 .- 1573-3432. ; 45:12, s. 1447-1453

    • To determine the best discriminative items for identifying young children with autism spectrum disorders (ASD), we conducted a secondary analysis using longitudinal cohort data that included the Japanese version of the 23-item modified checklist for autism in toddlers (M-CHAT-JV). M-CHAT-JV data at 18 months of age and diagnostic information evaluated at age 3 or later from 1851 Japanese children was used to isolate six highly discriminative items. Using data from two different community samples (n = 1851, n = 665) these items were shown to have comparable psychometric values with those of the full version. Our results suggest that these items might work as a short form screener for early identification of ASD in primary care settings where there are time constraints on screening. © 2015 The Author(s)

  • Association Between Autistic Traits in Preschool Children and Later Emotional/Behavioral Outcomes
  • 2017
  • Ingår i: Journal of autism and developmental disorders. - : Springer. - 0162-3257 .- 1573-3432. ; 47:11, s. 3333-3346
  • Tidskriftsartikel (refereegranskat)abstract
    • Although children with a greater number of autistic traits are likely to have other mental health problems, research on the association between earlier autistic traits in preschool children and later emotional/behavioral outcomes is scarce. Using data from 189 Japanese community-based children, this study examined whether autistic traits at age 5 were related to emotional/behavioral outcomes at age 7. The results showed that prior autistic traits were subsequently associated with all emotional/behavioral domains. After controlling for baseline emotional/behavioral scores autistic traits continued to predict later emotional symptoms and peer problems. This study highlights that in addition to clinical ASD, it is also important to focus on subthreshold autistic traits in preschool children for better subsequent emotional/behavioral outcomes.

  • Stability of the acoustic startle response and its modulation in children with typical development and those with autism spectrum disorders : A one-year follow-up
  • 2017
  • Ingår i: Autism Research. - : John Wiley & Sons. - 1939-3792 .- 1939-3806. ; 10:4, s. 673-679

    • Auditory hyper-reactivity is a common sensory-perceptual abnormality that interrupts behavioral adaptations in autism spectrum disorders (ASD). Recently, prolonged acoustic startle response (ASR) latency and hyper-reactivity to weak acoustic stimuli were reported in children with ASD. Indexes of ASR and its modulation are known to be stable biological markers for translational research in the adult population. However, little is known about the stability of these indexes in children. Thus, the objective of our study was to investigate the stability of neurophysiological ASR indexes in children with ASD and typical development (TD). Participants included 12 children with ASD and 24 with TD. Mean startle magnitudes to acoustic stimuli presented at 65-105 dB in increments of 10 dB were analyzed. Average peak startle latency (PSL), ASR modulation of habituation, and prepulse inhibition were also analyzed. These startle measures were examined after a follow-up period of 15.7±5.1 months from baseline. At both baseline and in the follow-up period, children with ASD had significantly greater startle magnitudes to weak stimuli of 65-85 dB and more prolonged PSL compared with controls. Intraclass correlation coefficients for these ASR measures between both periods were 0.499-0.705. None of the ASR measures differed significantly between the two periods. Our results suggest that prolonged PSL and greater startle magnitudes to weak stimuli in children with ASD might serve as moderately stable neurophysiological indexes of ASD.
