Age of first walking (AOW) is reported to be later in autism spectrum disorder (ASD) compared with typical development. However, the relationship between AOW and variations in ASD symptoms across different neurodevelopmental disorders is largely unknown. This study investigated AOW and its association with autism symptom severity in a large sample…

The autism spectrum disorder phenotype varies by social and communication ability and co-occurring developmental, behavioral, and medical conditions. Etiology is also diverse, with myriad potential genetic origins and environmental risk factors. Examining the influence of parental broader autism phenotype--a set of sub-clinical characteristics of…

Background: Evidence of the effectiveness of therapy for older children with (developmental) language disorder (DLD), and particularly those with receptive language impairments, is very limited. The few existing studies have focused on particular target areas, but none has looked at a whole area of a service. Aims: To establish whether for…

We compared ratings on the Three-Item Direct Observation Screen test for autism spectrum disorders completed by pediatric residents with the Social Communication Questionnaire parent reports as an augmentative tool for improving autism spectrum disorder screening performance. We examined three groups of children (18-60 months) comparable in age…

Each year, the Interagency Autism Coordinating Committee (IACC) releases its annual list of scientific advances that represent significant progress in the field. The 20 studies selected have given new insight into the underlying biology of autism spectrum disorder (ASD) and potential risk factors, tested approaches for improving early screening…

The prevalence of autism spectrum disorders (ASD) continues to be a source of debate among researchers and clinicians. Prevalence studies are of the utmost importance in order to obtain an accurate picture of the true prevalence rate of ASD and because these rates continue to be on the rise. To date, studies examining prevalence rates have…

This study investigated differences in co-occurring diagnoses made in females compared to males with autism spectrum disorders in 913 children (746 males and 167 females) living in the United States with a current autism spectrum disorder diagnosis identified via caregiver-reported data from the National Survey of Children's Health 2007. The…

Analysis of the data from Center for Disease Control's autism surveillance program found that the median age of identification of children with autism is 5.7 years. Being male, having an IQ of 70 or lower, and having developmental regression are the factors linked to a younger age of identification. There is a need for research, innovation, and…

As part of an ongoing clinical service program for children with developmental delay in an Asian developing country, we analyzed the cognitive attributes of 362 Taiwanese children (average age 48.5 plus or minus 12.9 month-old) with uneven/delayed cognitive development as they were assessed repeatedly with average duration of 39.7 plus or…

This cross-sectional study examined perceived access to services, quality of care, and family impact reported by caregivers of children aged 3-17 years with autism spectrum disorders, as compared to caregivers of children with other developmental disabilities and other mental health conditions. The 2009-2010 National Survey of Children with…
