Changes in Autism and Co-Occurring Conditions from Preschool to Adolescence: Considerations for Precision Monitoring and Treatment Planning.

Purpose: To describe retention of an autism spectrum disorder (ASD) diagnosis from preschool to adolescence and the most common co-occurring diagnoses among children with ASD in preschool and adolescence. A second objective was to identify co-occurring diagnoses more likely to emerge between preschool and adolescence among children with ASD vs. another developmental or mental health diagnosis in preschool.

Depressive symptoms and activity engagement in autistic adolescents and those with other developmental disabilities.

Background: Autistic adults and those with other developmental disabilities (DD) have increased depressive symptoms and decreased activity engagement when compared to those with no DD. Few studies explore activities related to depressive symptoms in autistic people and those with other DD during adolescence.

Objective: The objectives of this analysis were to describe depressive symptoms and activity engagement among autistic adolescents and those with other DD and no DD and explore types of activities associated with depressive symptoms, stratified by study group.

Risk factors and clinical correlates of sensory dysfunction in preschool children with and without autism spectrum disorder.

Sensory dysfunction is a common feature of autism spectrum disorder (ASD). The objectives of this analysis were to examine risk factors and clinical correlates of sensory dysfunction in preschool children with and without ASD. Children aged 2-5 years were enrolled in a multi-site case-control study.
