Active clinical trials for "Autism Spectrum Disorder"

This is an open, pilot study of neural mechanisms of cognitive-behavioral therapy for anxiety in children with high-functioning autism spectrum disorder (ASD). In addition to the core symptoms, approximately forty percent of children with ASD exhibit clinically significant levels of anxiety. Cognitive-Behavioral Therapy (CBT) is a promising treatment for anxiety in children with high-functioning ASD, but the neural mechanisms of this treatment have not been studied. CBT teaches emotion regulation skills such as cognitive reappraisal, followed by behavioral exposure to anxiety-provoking situations. The investigators propose to investigate the neural mechanisms of CBT for anxiety by evaluating fMRI indices of socioemotional functioning before and after treatment in children, ages 8 to 14, with high-functioning ASD. Dysfunction of the amygdala and its connectivity with prefrontal cortex has been implicated in co-occurring ASD and anxiety. In the investigators research, compared to typically developing controls, children with ASD have shown lower activation in several regions of prefrontal cortex and a lack of down-regulation in the amygdala during a task of emotion regulation. Based on these observations, the investigators propose that a positive response to CBT for anxiety in children with ASD will be associated with increased activation of several regions in the prefrontal cortex as well as increased functional connectivity between prefrontal regions the amygdala during the task of emotion regulation. The primary aim of this pilot study is to examine the effects of CBT on the neural basis of anxiety in ASD by collecting fMRI data during emotion regulation, face perception, and rest before and after treatment. The investigators hypothesize that CBT will increase prefrontal activity, decrease amygdala reactivity, and enhance amygdala-prefrontal functional connectivity during emotion regulation. The investigators also hypothesize that CBT will decrease amygdala reactivity during perception of emotional faces. Additional analyses will be conducted to explore change in resting-state functional connectivity before and after CBT for anxiety in children with ASD.

This is a Brazilian multisite study to test the efficacy of an Applied Behavior Analysis (ABA) parent training using video modeling to teach parents of children with Autism techniques to apply to their children in order to improve eye contact and joint attention behaviors. Our hypothesis is that children with Autism whose parents will be trained by videomodeling will have better eye contact and joint attention behaviors compared to children with Autism whose parents will not be trained.

This is a pilot, randomized, placebo-controlled trial of omega-3 fatty acids in autism. Autism, originally described by Kanner in 1943, is among the most severe of neurodevelopmental disorders. It is a Pervasive Developmental Disorder (PDD) affecting social and communicative functions and is also characterized by repetitive behaviors/restricted interests. It is also frequently accompanied by significant aggression, self-injury, irritability and hyperactivity, making care for these individuals an even greater challenge for families or institutional settings. Autism severely impacts the affected individual and family members, causing life-long functional impairment. In this protocol the investigators will use the terms "autism" and "autism spectrum disorder (ASD)" interchangeably to refer to Autistic disorder, Asperger Syndrome and PDD-Not Otherwise Specified (NOS).

Many children and adolescents with autism spectrum disorder (ASD) experience high levels of anxiety which can further inhibit their ability to master developmental tasks such as succeeding in school and developing and maintaining friendships. Despite the need for effective treatments for children with ASD and anxiety, there have been few studies that have addressed this issue. Recently, preliminary evidence has supported the use of cognitive-behavioral therapy (CBT) to treat anxiety disorders in children with ASD. This study will utilize a CBT treatment program called Coping Cat. Coping Cat has been found to be one of the most effective treatments for typically developing children with anxiety and has also been shown to be effective for treating anxiety in children with other disorders such as physical impairments, selective mutism, and Attention Deficit Hyperactivity Disorder. The investigators goal is to demonstrate that Coping Cat is an effective treatment for children with ASD and anxiety. Finding effective treatments for children with ASD and anxiety could increase adaptive social relationships, decrease stress among families, and prevent the maintenance of anxiety into adulthood.

This multi-center, randomized, double-blind, parallel group, placebo-controlled, proof of concept study will investigate the efficacy and safety of RG7314 in adult participants with ASD. In Stage I of the study, participants will be randomized in 2:1 to receive daily oral doses of 1.5 milligrams (mg) RG7314 or placebo for 12 weeks. After an independent safety review, the study may proceed to Stage II. In Stage II of the study, additional participants will be randomized in 2:1 to receive daily oral doses of 4 mg RG7314 or placebo for 12 weeks. After an independent safety review, Stage III will be started wherein additional participants will be randomized in 2:1 to receive daily oral doses of 10 mg RG7314 or placebo for 12 weeks. During Stage III, safety will be reviewed by independent safety review twice and if no safety signal is observed, then additional participants will be randomized in 1:1:1 either to receive 1.5 milligrams per day (mg/day) or 10 mg/day RG7314 orally or placebo for 12 weeks in Stage IV.

Autism Spectrum Disorders (ASD) are characterized by difficulties in language, social communication, and repetitive and restricted behaviors. ASD affects as many as 1 in 90-150 children. Sleep issues/insomnia is very common in children with ASD (50-80%). Insomnia has a negative impact on both the developmental and behavioral function of the child and the quality of life for the family. Causes of insomnia in children with ASD are multifactorial and can be difficult to treat effectively. Low iron stores, as manifest by low serum ferritin levels, is also common in children with ASD. Both insomnia and low iron stores are associated with Restless Legs Syndrome (RLS) and Periodic Limb Movement of Sleep (PLMS). Children with ASD often have difficulty communicating symptoms or tolerating Polysomnography (Sleep Study). This makes establishing a diagnosis of RLS or PLMS very difficult in children with ASD.

The goal of this study is to conduct an efficacy trial to determine whether an early communication intervention which blends two evidence-based interventions, Enhanced Milieu Teaching (EMT) and Joint Attention, Symbolic Play and Regulation Intervention (JASPER), improves social communication in toddlers with Autism Spectrum Disorder (ASD).

The purpose of this study is to investigate the effects of several applied behavior teaching procedures on the use of multi-word utterances by children with autism.

The purpose of the study is to determine if intranasal ketamine shows initial evidence of safety, tolerability and efficacy for the treatment of social impairment in individuals with Autism Spectrum Disorder.

This research study is carried out to examine the effects of Phosphatidylserine-Omega 3 supplements (i.e., Vayarin) among children with Autism Spectrum Disorder (ASD) and ADHD. Participants will be randomised either to receive the Vayarin treatment (Intervention group) or to a Control group.
