Filter by:The goal of this clinical trial is to evaluate the effectiveness of using a Microskills video training library for training parents of adolescents with ASD in talking with their teens about relationships and sexual health topics. The main questions it aims to answer are: - Does using SkillTalk increase parents' skills in communicating with their teens about relationships and sexual health? - Does using SkillTalk increase the frequency of conversations about relationships and sexual health? - Does using SkillTalk increase parents' confidence in their ability to communicate with their teens about relationships and sexual health? - Does using SkillTalk improve teen knowledge, attitudes, and behavior around sexual health and relationships? Participants will be asked to: - Take a survey at the beginning of the study, the end of the study, and at 3-month follow up - Record a short conversation between the parent and teen dyad about a sexual health topic at the beginning of the study, at the end of the study, and at 3-month follow up. - Watch a minimum of 85% of the 60 minutes of video assigned - Complete a conversation log at the end of each week during the study period, and once a month during the 3-month follow-up period.
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.
Growing evidence demonstrates the critical contribution of the neuropeptide oxytocin in the development and maintenance of autism, due to its role in social behaviour and learning processes. While some preliminary findings in oxytocin administration trials have been promising, a complete understanding of the effects of long-term oxytocin administration in autism remains elusive, as participant numbers in oxytocin administration studies in autism have been small, most studies exclusively recruit males, and reproducibility has been inconsistent. To address this critical knowledge gap, this project will include a double-blind, placebo-controlled, randomized controlled crossover trial of a four-week intranasal oxytocin treatment (24 international units, twice-daily) in 128 male and female youth with ASD aged 12-20, with social and repetitive behaviors as primary outcome measures. The investigators predict that intranasal oxytocin treatments will increase performance on social behavior measures and reduce repetitive behaviors using caregiver-reported measures. Along with the investigation of oxytocin's long-term effects, the investigators will also assess the impact of oxytocin administration on computer-based laboratory tasks that can precisely measure how participants process social cues and disengage with repetitive behaviours. In addition, an electrocardiogram will be collected to evaluate the impact of oxytocin administration on parasympathetic nervous system activity.
The goals of this pilot study are to assess the presence of harmful germs for gums and to assess oral health in adults with autism spectrum disorder.

Change in ABC-C score following 6 weeks of intervention. • Adverse events reported in both groups Details of intervention- One arm of the study population to get Risperidone 1mg/day for a total duration of 6 weeks and another arm to get Aripiprazole 2mg/day for a total duration of 6 weeks. Baseline assessment of Serum Glutathione, Serum SOD, ISAA scale, ABC-C scale will be done and same will be assesssed at 6 weeks follow up.
The investigation team propose in this study to specifically evaluate the feasibility of using oxytocin in the form of an intranasal spray in a specific population of children with autism spectrum disorder and intellectual disability. The lack of studies centered on this population on the one hand, and on the other hand the severity of challenging behaviors presented by these children, make questionable the direct transfer of methods of care used in patients who do not present these challenging behavior. In this sense, the establishment of oxytocin treatment in these children requires a preliminary phase of feasibility assessment before being able to consider a comparative trial of the randomized clinical trial type.
The goal of this interventional study is to assess the knowledge of caregivers of children with Autism Spectrum Disorder (ASD) regarding oral and nutritional health and the burdens they encounter in dealing and caring for these children. The main aims to answer are: Educating caregivers on - Diet diversities - Improving oral health habits Participants will have to - Fill questionnaires - Undergo educational sessions - Fill post education questionnaires Researchers will compare pre and post educational questionnaires to see if the intervention makes a difference.
The role of gut microbiome was recently raised in the pathogenesis of neurodevelopmental disorders including autism spectrum disorder (ASD). In view of these evidences, together with poor conductance of researches on gut microbiota in ASD patients in Egypt, in addition to the absence of definite medical test or biological marker for diagnosis of ASD, the present study is designed to study clinical risk factor of autism and the predominant gut microbiome in autistic children in an attempt to identify gut bacteria which are likely related to ASD and to correlate these bacteria and clinical variables with the severity of autism. Interestingly, the totality of the studies focusing on the fecal metabolome features in ASD has investigated the differences between subjects with and without this disorder, while ignoring potential correlations between microbiome, metabolome and ASD severity
This study aims to compare two screening strategies for identifying infants with a potential risk of Autism Spectrum and Neurodevelopmental Disorders to provide early access to care and increase the likelihood of a favorable outcome
Autism spectrum disorder (ASD) is a neurodevelopmental disorder of unclear etiology. There are theories depicting the importance of sex steroid hormones in autism, since the prevalence of the disorder is male-biased. What makes boys more vulnerable to achieve the diagnosis of autism remains unclear. One of the theories strengthens the importance of fetal organizational effect of testosterone on brain development. Baron Cohen with coworkers showed that elevated fetal levels of several androgens including testosterone were high in male-fetuses who later in postnatal life achieved the diagnosis of autism and fetal testosterone levels were positively correlated with autistic traits in general population. Females with conditions of abnormal prenatal exposure to testosterone and its sex steroid precursors, such as congenital adrenal hyperplasia and polycystic ovary syndrome, were found to have higher rate of autistic traits as well as their children were of higher risk of developing autism. However, the exact mechanism by which these hormones influence the manifestation of autistic traits remains undiscovered. Another model explaining higher prevalence of ASD in males is a female protective model which suggests that multiple genetic factors contribute to the development of ASD and that higher threshold of genetic liability is required in females compared to males. Zhang et al. demonstrated genetic evidence of sex differences in ASD confirming female protective model, employing investigation of de novo mutations, common variants of ASD candidate genes and their co-expression in male and female brain. During infancy: The Gonadotropin releasing hormone (GnRH) pulse generator is reactivated by 6 to 10 days after birth. This period, termed the mini puberty of infancy, was first described in the 1970s. During mini puberty, luteinizing hormone (LH) levels approximate pubertal concentrations, reaching a peak between 16 and 20 days of life. Serum testosterone levels rise in response to rising concentrations of LH, paralleling an increase in Leydig cell number and testicular testosterone concentrations. Serum testosterone levels peak from 1 to 3 months (210 ± 130 ng/dL or 7.28 ± 4.51 nmol/L on day of life 30) and decline by roughly 50% per month reaching prepubertal levels by 7 to 12 months of age. Dihydrotestosterone (DHT) concentrations parallel the rise in testosterone, reaching pubertal values during the early postnatal period. During puberty: Testosterone is produced primarily by the testes, though a small amount is also made in the adrenal gland. Gonadarche refers to the onset of sex steroid production from the gonads and occurs in response to pulsatile production of GnRH from the hypothalamus, which in turn stimulates production of LH and Follicle stimulating hormone (FSH) from the pituitary gland. LH stimulates the Leydig cells to produce testosterone, whereas FSH stimulates the Sertoli cells to proliferate and initiate spermatogenesis. Active androgens are synthesized via two alternative pathways. The first of them is known as the classic "frontdoor" pathway with pregnenolone serving as androgen precursor, which underwent a conversion to DHEA and subsequently to androstenediol. These metabolic steps are catalyzed by CYP17A1 (in the C17,20-lyase step) and (mostly adrenal) AKR1C3 enzyme, respectively. Dehydroepiandrosterone (DHEA) and androstenediol are readily sulfated by SULT2A1 in adrenal cortex and their sulfates serve as the stock pool for the production of active androgens of the adrenal origin as the production of androgens in early childhood of boys is limited to extra-gonadal tissues, such as adrenal, skin, etc. These sulfated primary androgens may be subsequently deconjugated and metabolized by HSD3B1 and HSD3B2 isoforms to androstenedione and Total testosterone (TST) and then to 5α/β-reduced 17-oxo- and 17β-androgens, respectively. In addition, the androstenedione may be readily converted to testosterone by adrenal AKR1C3. From the aforementioned substances, TST, 5α-dihydrotestosterone, and 11-oxo-testosterone are known as the most potent bioactive androgens. Besides the "frontdoor" pathway the dihydrotestosterone may be also formed by so called "backdoor" pathway. This pathway is based on a direct conversion of 5α/β-reduced pregnane steroids (C21) to their 5α/β-reduced androgen (C19) metabolites which is catalyzed by the same enzyme converting pregnenolone to DHEA (CYP17A1 in the C17,20-lyase step). These 5α/β-reduced androgen (C19) metabolites include also the most active androgen 5α-dihydrotestosterone. The "backdoor" pathway is crucial for androgen synthesis in marsupials but may also be active in various human steroid-related disorders.
