Filter by:To date, it is well documented that the gut microbiota (GM) influences numerous physiological processes in the healthy "host". The alteration of the composition and function of the intestinal microbiota, commonly referred to as "dysbiosis", is associated with many pathological conditions. The high co-morbidity between inflammatory bowel diseases and psychiatric symptoms such as anxiety and stress and the frequent presence of gastrointestinal dysfunctions in autistic patients have highlighted a possible implication of GM in psychiatric disorders. The ability of GM to communicate with the central nervous system and the possible influence on behavior led to the discovery of the existence of a microbiota-gut-brain axis. Clinical and experimental data suggest a possible role of modifications in the composition and function of the intestinal microbiota (impaired production of short-chain fatty acids, SCFAs) in major psychiatric disorders such as autism spectrum disorders (ASD). ASD is a severe neurological condition characterized by severe stereotypical behaviors and deficits in linguistic and social interaction. The prevalence of ASD in children is continuously increasing in Western countries. The pathogenesis of ASD is still poorly defined. The clinical manifestations of ASD are the result of complex interactions between genetic, epigenetic, environmental and microbiological factors. The improvement in gastrointestinal symptoms of autistic patients after short-term oral treatment with antibiotics and probiotics clearly indicated a role of the metabolites of MI in ASD. In particular, an alteration in the phyla of Bacteroidetes and Firmicutes in fecal samples from autistic children has been described with conflicting results. Williams and colleagues (2011) evaluated a significant increase in the Firmicutes / Bacteroidetes ratio in intestinal biopsies of autistic children with gastrointestinal disorders. It has also been shown in animal models of ASD that dysbiosis is positively associated with an increase in butyrate levels and inversely associated with the "score" of the severity of ASD symptoms. Alterations in nutritional status, eating habits and adverse reactions to food appear to be more frequent in children with ASD. Several studies support the hypothesis that children with ASD have a greater refusal of food, requiring specific food presentations or eating a reduced variety of foods compared to children without ASD. These conditions are associated with dysbiosis. Preliminary data suggest that particular elimination diets and / or modifications of the intestinal microbiota can determine a positive effect on the symptoms of ASD. A better knowledge of the composition and functions of the intestinal microbiota also in relation to eating habits and the presence of adverse reactions to food in the child with ASD could facilitate new effective strategies for the prevention and treatment of these conditions.
Purpose. The goals of the study are to assess the safety of the intravenous infusion of umbilical cord blood (UCB) cells in patients with autism and to confirm changes in social/ communicative skills and cognitive functioning after four infusions of ABO/Rh-matched UCB stem cells. Material and methods. The sample comprises 30 patients (27 males, 3 females) aged between 3 and 11 years with ASD under the care of the National Medical Research Center for Psychiatry and Neurology (Saint-Petersburg, Russia). Participants are randomly assigned to either the control group (14 males, 1 female) or the experimental group (13 males, 2 females). The experimental group receives intravenous injections of UCB cells four times with a two-week gap between injections. The control group receives standard therapy. The dynamic of cognitive functions and social/communicative skills assess with Checklist for autism spectrum disorders (CASD), Autism treatment evaluation checklist (ATEC), subscales of Wechsler Intelligence Scale for Children (WISC) - "Digit Span", "Picture completion", "Block design", "Coding".
Individuals with autism spectrum disorders (ASD) commonly experience variances in tactile behaviors, such as hypersensitivity to light touch stimuli, altered texture discrimination, and hyporesponsivity to pain. Researchers aim to investigate the somatosensory sensitivity and sensorimotor integration utilizing novel, objective behavioral assays and TMS. The main purpose is to study brain plasticity (the changes that occur in the brain through experience) in individuals with autism spectrum disorders.
Clinically, infants with Autism spectrum often display gross motor delays in supine, prone, and sitting skills in their first year of life.
The purpose of this study is to determine the efficacy of Melodic Based Communication Therapy (M.B.C.T.) for increasing oral expressive skills in nonverbal children with autism spectrum disorders. MBCT has previously been shown to facilitate an improvement in expressive vocabulary, verbal imitative abilities, number of vocalizations, and social language development in nonverbal children with autism ages 5-7. However, earlier studies were small and did not examine the effects of M.B.C.T. on a younger and older population. This study will examine its effectiveness across a broader sample group. Additionally, this study will examine further predictors of success including but not limited to chronological age, developmental age, the frequency of repetitive/stereotypic behaviors, receptive language score, and social language score.
This pilot clinical trial tests the hypothesis that certain blood metabolite levels can be used to predict Autism Spectrum Disorder (ASD). The study cohort will consist of 200 participants between the ages 18 and 60 months who have been referred to a developmental pediatric center for clinical evaluation of ASD or other developmental delay. Two selected sites will enroll 75 participants each with another 50 typically developing participants. Participants will receive a physical exam (including a dysmorphology evaluation), ADOS, VABS, MSEL, DSM-5, and M-CHAT assessments, and receive a diagnosis. A fasting blood draw is required, consisting of 2 mL vacutainer tubes (max 4 mL). Sites must process blood according to sponsor requirements (outlined in the Sponsor's Laboratory Manual). Certain metabolite levels in the blood will be used for diagnostic screening test development.
This study will examine if a virtual delivery of a group Cognitive Behavioural Therapy (CBT) program, specifically using "Facing Your Fears" (FYF) curriculum, is helpful in improving anxiety symptoms for children and youth with ASD. This study will adapt the FYF program for virtual delivery using a platform called "Zoom for Healthcare" and examine its effectiveness.
The Early Start Denver Model (ESDM) has shown its efficiency in the early management of ASD. The study aims to evaluate the efficiency of a new type of management based on a semi-intensive center-based intervention (8h per week) coupled with a MOOC (Massive Online Open Course: a teaching and learning intervention based on instrumental and interactive teaching situations) for remote parental training/supervision. The goal is to determine if compared to the ESDM reference intervention (15h per week), this type of care can bring, a sufficient improvement in child development course and decreased symptoms of autism in young children, and if it could be, therefore, better suited to the needs of children and their family, bypassing the previously stated obstacles.
The hypothesis of the study is that photobiomodulation reduces symptoms of autism. Participants will be children between the ages of 2 and 6, who have been diagnosed with moderate to severe autism. Transcranial photobiomodulation will be administered to the children in the experimental condition twice a week for 8 weeks. Results will be measured through parental interviews, standardized CARS2 (Childhood Autism Rating Scales, 2nd Edition) and data collected from EEG.
This study aims to develop a culturally-sensitive parent-training intervention to enhance socioemotional functioning of young children (aged 3-6) with Autism Spectrum Disorder (ASD) in Mainland China. The investigators will conduct randomized controlled trials to evaluate the effectiveness and feasibility of this program in a pilot study and then a large-scale community-based study in Shenzhen, China, to examine the generalizability of the treatment outcomes of this intervention for Chinese children with ASD.
