Active clinical trials for "Autistic Disorder"

This study will test the hypothesis that brain systems are differentially regulated by serotonin in individuals with and without Autism Spectrum Disorder.

The purpose of this study is to characterize the developmental phenotype of ASD and ID and to identify biomarkers using advanced MRI methodology and electrophysiological biomarkers of synaptic function and connectivity predictive of ASD and ID presence and severity in patients with TSC. In addition, this study will be establishing infrastructure for the collection and storage of human bio-specimens, including genetic material, from TSC patients and their family members with ASD.

Behavioral testing is the gold standard for diagnosing ASD. These tests, including ADOS and ADI-R, are subjective, require trained staff to administer, are time-consuming, and can only be administered at a later age. Blood-, urine- or stool-based diagnostic biomarker test for ASD would enable objective early diagnosis, potentially even before clinical symptoms are present, eliminate the need for trained staff and enable early intervention. Such a test would not only conserve money and time but would also provide clues to ASD pathogenesis.

This is an 18 to 54 week study assessing the efficacy of Full-Spectrum Medicinal Cannabis Plant Extract 0.08% THC (NTI164) on the severity of autism spectrum disorder in young people.

Autism Spectrum Disorder (ASD) is a neurodevelopment disorder characterized by impairment in social interaction, communication, and behavior, as well as sensory challenges. In addition, secondary symptoms can appear, such as gastrointestinal disorders. Gut microbiota has an important role in the harvest of nutrients and energy from our diet. It influences a wide range of metabolic, developmental, and physiological processes such as the maintenance of the gut epithelial layer, immune system development, protection against pathogens, detoxification and xenobiotics degradation. The ecosystem of a healthy human gastrointestinal (GI) tract is mainly populated by Firmicutes and Bacteroidetes phyla, to a lesser extent by Actinobacteria and Proteobacteria, in this case the microbiota is in an eubiosis condition. Whether a disturbance of the microbial ecosystem occurs, gut microbiota is in a dysbiosis condition and it could lead different metabolic disorders. The two-way communication between gut microbiota and central nervous system (CNS) affects stress response, pain perception, neurochemistry and several disorders. The gut microbiota in ASD patients revealed some peculiarities such as the high percentage of Propionibacter and Clostridium, well known for their production of pro inflammatory metabolites, or an increment of Sutterella spp. and Ruminococcus torques, which are negatively associated with the health of the gut. Recent studies suggest that also the oral microbiota may be involved in ASD symptoms assuming the existence of a "microbiota-oral-brain axis". ASD patients are often suffering of several oral cavity disorders like caries, gingivitis and periodontitis, probably due to the poor oral hygiene. These disorders are linked to a dysbiosis of the oral microbiota: the characterization of the ASD subjects oral microbiota showed a lower biodiversity of bacteria species and different levels of specific bacteria, comparing to the controls. Several studies suggest that some bacteria species invade the blood-brain barriers as well as their metabolites, triggering inflammatory response and an alteration of the metabolic activity in the CNS. It has been demonstrated that ASD patients have a high level of pro-inflammatory cytokines and chemokines in the cerebrospinal fluid and an upregulation of the microglia. The oral microbiota could also affect the lower GI tract and have a significant role within the ASD-associated GI disorders and CNS inflammation

Early identification and diagnosis of autism spectrum disorder (ASD) is necessary to promote access to early treatment. Despite the high incidence, in Italy it is estimated that 1 in 77 children (age 7-9 years) (Narzisi et al., 2018), the diagnosis and the choice of rehabilitation treatment for patients with Autism Spectrum Disorder (ASD) are still based on clinical observation. In the absence of targeted pharmacological therapies, early surveillance and evaluation aimed at timely intervention represent the only successful strategy to reduce the severity of symptoms (Palomo R et al., 2006) and improve the quality of life of children affected by ASD and their families, thus also leading to a reduction in costs for the National Health Service (Ganz ML. 2007). However, compared to the great advances in neuroscience, the clinical management of autistic individuals is seriously lagging behind, and the disorder is often diagnosed after 3-4 years of age despite the presence of deficits starting from the very first months of life (Zwaigenbaum L et al. al., 2013). The aim of this project is to bridge the gap between research and clinic, thanks to the convergence of multiple biological and clinical data.

Proof of concept, multicenter, randomized, double-blind, placebo-controlled, parallel-group, study to investigate the effect, safety, tolerability and pharmacokinetics of pitolisant in male children and adolescents with Autism Spectrum Disorders.

The goal of this project is to measure the clinical utility of an objective and quantitative eye-tracking assay collected on a standalone, mobile investigational device to accurately screen 9-month-old infants for autism spectrum disorder and other actionable delays.

Children with Autism spectrum disorders have speech disorders, which in turn aggravate communication difficulties and lead to an increase in their core symptoms. This experiment attempts to investigate the efficacy of Chinese language oral motor therapy in improving various aspects of articulation, language ability, and behavior of children with autism in conjunction with the International General Autism Scale, and provides a basis for the rational formulation of clinical treatment plans.

The goal of this study is to determine the impact of neuromodulation to the cerebellum on social and executive functions in neurotypical young adults and young adults with autism.
