Objectives: The aim of this study was to determine the efficacy and tolerability of gastrin-releasing peptide (GRP) for core symptoms of autism spectrum disorder.
Methods: This is a prospective, open-label study with 160 pmol/kg of GRP tested in 10 children with autism. Outcome measures used were the Clinical Global Impressions-Improvement Scale, Aberrant Behavior Checklist (ABC), Childhood Autism Rating Scale, and Autism Diagnostic Interview-Revised.
Purpose: To investigate the relationship between language regression and the subsequent social-communicative development of preschool children with Autism Spectrum Disorder (ASD).
Methods: Thirty children with ASD participated in the study and were divided into two groups: with (n=6) and without (n=24) language regression. Language regression was assessed by the Autism Diagnostic Interview-Revised and the social-communicative development was measured by the Autism Diagnostic Observation Schedule.
