It is important to diagnose autism spectrum disorder at an early age and to start an early intervention program without delay. In this study, we aimed to validate the Rapid Interactive Screening Test for Autism in Toddlers (RITA-T) in a group of Turkish children and found that the RITA-T which has been shown to be a valid and reliable screening test for 18- to 36-month-old children in studies conducted in different countries, is also valid in Turkish children. Similar to previous studies, our results showed that the RITA-T has good sensitivity and specificity in distinguishing children with autism spectrum disorder.

This study aims to examine auditory processing, P300 values and functional impairment levels among children with Attention Deficit and Hyperactivity Disorder (ADHD), Specific Learning Disorder (SLD), ADHD+SLD and healthy controls. Children with ADHD (n = 17), SLD (n = 15), ADHD+SLD (n = 15), and healthy controls (n = 15) between the ages of 7-12 were evaluated with K-SADS, Weiss Functional Impairment Rating Scale, Turgay DSM-IV Disruptive Behavior Disorders Rating Scale, The Mathematics, Reading, Writing Assessment Scale and Children's Auditory Performance Scale (CHAPS). Auditory P300 event-related potentials and Spectral-Temporally Modulated Ripple Test (SMRT) were applied.

Introduction: The mechanism of ubiquitination-related abnormalities causing neural development problems is still unclear. We examined the association between autism and serum transactive response DNA-binding protein-43 (TDP-43) and ubiquitin c-terminal hydrolase-L1 (UCH-L1) levels, both of which are members of the ubiquitin-proteosome system.

Methods: We measured serum levels of TDP-43 and UCH-L1 in 24 children with autism and 24 healthy children.

Clinical diagnosis of autism spectrum disorder (ASD) can be conceptualized as the extreme end of the distribution of subclinical autistic traits related to genetic susceptibility factors (broad autism phenotype (BAP)) in the general population. Subclinical autistic traits are significantly more common among unaffected first-degree relatives of probands with autism. However, there is a significant heterogeneity of autistic traits in family members of individuals with ASD and severity of autistic traits are not significantly different from controls in the majority of these relatives.

α-Synuclein (α-syn) and tau proteins are thought to be related with the synaptic loss and cell death underlying several important neurodegenerative diseases. The aim of our study was to investigate serum α-syn and tau levels in autism.
