Active clinical trials for "Autism Spectrum Disorder"

This study investigates the prevalence, phenomenology, and correlates of anxiety in preschool children with autism spectrum disorder (ASD) across a two-year period. Attention bias to threat, a potential objective marker of anxiety, also is examined using eye tracking methods.

The purpose of this study is to develop an Auditory Brainstem Response (ABR) based neurological screening method to detect increased risk for Autism Spectrum Disorders (ASD) and other neurological conditions in newborns.

The main objective for this research study is to gather additional information to help confirm identification of new subgroups within the autism spectrum.

The study is a prospective randomized repeatability and reproducibility (R&R) study of the EarliPoint DeviceTM in pediatric subjects 16-30 months of age. The study will enroll subjects who are both clinically-positive and clinically-negative for ASD. The study will be conducted at a single center in the US. The Study consists of a screening period in order to review the subject's medical history to determine subject eligibility, followed by a device administration period during which subjects will undergo testing with the EarliPoint Devices and Expert Clinician Diagnosis (ECD) procedures to determine if they are clinically-positive or clinically-negative for ASD.

Although motor limitations are not currently considered a as clinical manifestation of autism spectrum disorder, they should not be ignored due to their high incidence and considerable influence on life quality functional activity

The purpose of this study is to provide a detailed description of language and cognitive profiles found among children and adolescents diagnosed with autism spectrum disorders (ASD). Participants with ASD ages 4-17;12 years who have limited verbal skills will be given comprehensive behavioral assessments to collect data that will advance our understanding of language-related processes in individuals with ASD, the knowledge of which will help in designing future interventions for this population.

The purpose of this study is tTho establish test-retest reliability of electrodermal markers used to quantify physiologic response to sensation using the Sensory Challenge Protocol in children with and without Autism Spectrum Disorder (ASD).

This study will prospectively enroll approximately 660 children, at least 18 months and less than 5 years of age, who have been referred to a pediatric developmental evaluation centers. Enrolled children will have blood drawn for RNA gene expression analysis and undergo a clinical evaluation to determine the presence or absence of a diagnosis of ASD. The sequential co-primary objectives of this study are: To develop an algorithm to classify blood RNA gene expression patterns to maximize agreement between the classification and a clinical assessment of presence or absence of Autism Spectrum Disorders (ASD). To prospectively assess the clinical sensitivity and specificity of the blood RNA gene expression classification algorithm (the SDX-002 test) in children referred to a developmental evaluation clinic for a possible developmental disorder.

This research is being done to determine whether transcranial direct current stimulation (tDCS) can improve certain mental abilities, such as speech, language and other efforts at communication in individuals with autism. In this research, battery powered device is used to deliver very weak electrical current to the surface of the scalp while participants are involved in tasks aimed at training or measuring communicative efforts, speech, language or related cognitive functions. Our aim is to find out whether tDCS will improve these mental abilities.

The purpose of this research study is to help us learn if children with Autism Spectrum Disorder (ASD) have gastrointestinal (stomach and intestine) problems more frequently than children without ASD do. The investigators hope to learn if children with ASD and gastrointestinal (GI) disorders have certain Problem Behaviors (PB), such as self-injury and aggression, more than children with ASD but no GI disorders do. The investigators want to learn if the Gastrointestinal Symptoms Questionnaire (GIQ) can help us tell which children with ASD also have gastrointestinal disorders. Hypothesis 1: Children with ASD exhibit high rates of symptomatic GI dysfunction that are not identified by current diagnostic evaluation. Hypothesis 2: Painful or discomfort-causing gastrointestinal dysfunctions contribute to an elevated incidence or severity of PB in an identifiable subpopulation of PB-expressing children. The investigators anticipate that the proposed study will raise the standard of medical care for children with ASD by improving current methods of identifying GI dysfunction and determining whether there is a significant relationship between GI dysfunction and PB in this population.
