Active clinical trials for "Down Syndrome"

The goal of this clinical trial is to test in people with down syndrome how does the INTORUS tool influence their psychomotor development. The main question it aims to answer is: - Does the INTORUS tool improve psychomotor development in people with Down Syndrome? The intervention program will be carried out during the Functional Habilitation sessions and will be carried out by the center's professionals. These sessions must be carried out in a quiet environment, without distractions so that the user can concentrate on carrying out the activities. It is important that the user attends the sessions in comfortable, sleeveless clothing, to allow the tool to slide smoothly through their upper limbs. Each session will consist of several exercises with their corresponding rest breaks described in the Intervention Protocol. Each session attendance will be recorded following an attendance record model created for the occasion. Participants will be divided into two groups randomly. The control group will receive an intervention treatment at the psychomotor level in the traditional way, following the protocols established in the center, and the intervention group will receive an intervention treatment at the psychomotor level with the INTORUS device. Randomization will be carried out using the Oxford Minimization and Randomization software.

Down syndrome (DS) is the most common chromosomal disorder; with the increasing life expectancy, about 80% of DS adults reach age 65 years old. Early Alzheimer's disease (AD) is the most common cause of death within this population. DS individuals already show AD neuropathology by the age of 30, while it becomes clinically recognized in their late forties. DS subjects also exhibit olfaction defects in adulthood. To date, there is no treatment available for the cognitive or olfactory defects in DS. The development of an effective treatment targeting cognitive dysfunction in DS adolescents/adults would be warranted. GnRH, a decapeptide secreted by hypothalamic neurons is the pilot light of reproduction in all mammals. Pulsatile GnRH acts on the gonadotrophs via the GnRH receptor (GNRHR) in the pituitary gland to stimulate LH and FSH, which themselves will act on the gonads to produce gametes and steroids. However, GNRHR are also expressed in cerebral cortex, hippocampus, amygdala, habenula, olfactory structures, and adrenal gland, suggesting that GnRH may have a role beyond reproduction. Recently, GnRH has been shown to be involved in the process of ageing and lifespan control. Notably, in murine models, GnRH acts as an anti-ageing factor, independent of sex hormones. While ageing is characterized by hypothalamic inflammation and diminished neurogenesis, particularly in the hypothalamus and the hippocampus, GnRH was able to promote adult neurogenesis. The regulation of GnRH secretion is complex and involves hormonal, neuronal input, and environmental factors. Prévot et al. recently explored cognition within the Ts65Dn model and showed an age-dependent loss of the ability to recognize new objects. Also, these mice exhibit defects in olfaction. Given the role of GnRH in anti-aging mice model, pulsatile GnRH or continuous GnRH infusion (leading to desensitization of the GNRHR) were given to the Ts65Dn mice for two weeks. Amazingly, pulsatile but not continuous GnRH therapy was able to recover cognitive and olfaction defects.

This partially randomized phase III trial studies the side effects of different combinations of risk-adapted chemotherapy regimens and how well they work in treating younger patients with newly diagnosed standard-risk acute lymphoblastic leukemia or B-lineage lymphoblastic lymphoma that is found only in the tissue or organ where it began (localized). Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy), giving the drugs in different doses, and giving the drugs in different combinations may kill more cancer cells.

Although some western studies have been conducted to determine the nature of eating problems and oral motor training in children with Down syndrome, these studies are limited. Most of the studies were done in Down syndrome infants. Since feeding is a skill that develops by 2 years of age and refines till 6 years of age (Delaney & Arvedson 2008), it is essential to study the children in this age group as well. Moreover, there is a dearth of studies investigating the impact of oral motor exercises on feeding problems of the child, which may, in turn, hinder the progress of the child during the intervention. Blissett J., (2018) reported that the behaviours of both caretaker, therapist and infant during feeding contribute significantly to the overall success of the feeding interaction as well as feeding performance. Parents/caregivers play an important role in feeding the child, as they have the first-hand exposure and experience in feeding their child, awareness of the child's feeding behaviours, likes and dislikes of food and communication behaviour during hunger. Consequently, they are the best people to describe their child's feeding problems. Hence, this study involves the administration of a scale on the parent/caregiver to elicit information about the physical, functional and emotional aspects of drooling. Such studies in the Egyptian context are limited. The paucity of literature makes it clear that there are deeper underlying complex issues about oral motor exercises in children with Down syndrome that needs to be investigated. The in-depth assessment and treatment of oral motor skills will provide valuable input to the physical therapists during the treatment of feeding problems in children with Down syndrome. This would help the therapist and clinician in planning and prioritizing the goals during therapy. The information will also help in counselling the caregivers, deciding the success or failure of feeding therapy and thereby help in predicting the prognosis of the child.

This study is a randomized, double-blind, placebo-controlled, crossover trial of extended-release liquid methylphenidate (XRMPH) to evaluate the sensitivity of the NIH Toolbox Cognition Battery (NIHTB-CB) to changes in cognition in children and adolescents ages 6 to 17 with intellectual disability (D) and comorbid Attention Deficit Hyperactivity Disorder (ADHD). The sample will include 68 males or females (expected male: female ratio of 1.8:1 with ID and ADHD as determined by structured diagnostic interview and Conners 3 scores. Additional inclusion criteria will include Full Scale IQ above 50 and mental age greater than or equal to 4 years. In addition, participants must be able to complete NIHTB-CB testing and provide valid scores at baseline. After baseline testing, participants will then be randomized to drug or placebo in a 1:1 ratio (N=34 per group) at the end of the baseline visit. XRMPH in oral suspension supplied as Quillivant XR in 5 mg/ml (Tris Pharma, Monmouth Junction, NJ) will be the active treatment. The XRMPH or matching placebo will be started at a dose of 0.3 mg/kg/day and individually titrated over two weeks. Phone calls at the end of weeks 1, 2, and 3 will be used to collect adverse event and response data. If there is no evidence of side effects and ongoing symptoms of ADHD, the dose will be increased to 0.5 mg/kg/day at one week and 0.7 mg/kg/day at 2 weeks (maximum dose of 60 mg per day consistent with FDA labeled use in youth). The Clinical Global Impression (CGI) will be used as a guide to define optimal dose. If side effects occur the dose will be reduced to the dose level at which there were no side effects. Final optimal dose will be established by the end of week 3 and this will be maintained for 2 weeks until 5 weeks post randomization, at which time the follow-up parent and teacher Conners scales, NIHTB-CB, Go/No-Go, and PedsQL will be completed. Participants will have a washout period of 1 week, will then complete re-assessment at the second baseline, and then will cross over to the other treatment (Quillivant to placebo; placebo to Quillivant), also in a double-blind fashion. In the second treatment arm, patients will have the same titration, monitoring and treatment periods as in the first arm, again followed by repeated assessments at the conclusion of 5 weeks. The accrual of participants and number of visits is shown in the Timeline per 6-month period.

The purpose of the study is to compare the effect between of whole-body vibration and gravity force stimulation on postural stability in children with Down syndrome.

This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography (OCT) and OCT angiography (OCTA) as well as ultra-widefield (UWF) fundus photography to assess the structure and function of the retinal and choroidal microvasculature and structure in persons with mild cognitive impairment (MCI) and Alzheimer's Disease (AD), Parkinson's Disease (PD), or other neurodegenerative disease, diseases as outlined.

As basic and behavioral science identify new ways to improve cognition and behavior in individuals with Down syndrome (DS), the lack of rigorous outcome measures represents an important problem for interpreting findings. Null findings in clinical trials could result from insensitive outcome measures, rather than ineffectiveness of treatment. The long-term goal is to improve measurement of outcomes for children and adults with DS. Towards that goal, the investigators propose to test and refine a battery of cognitive measures that can be used in treatment studies focused on school-aged children and adults with Down syndrome. The batteries are designed to assess key domains of the DS phenotype where gaps remain in outcome measures, including attention, executive function, learning and memory, processing speed, and social cognition. The investigators will examine the psychometric properties of measures (test-retest, validity, sensitivity to change), and to evaluate differences in the psychometric properties of measures as a function of variations in participant age, gender, degree of ID, and the participants' physical health and medical comorbidities. The investigators will evaluate at least 80 children and 50 adults with Down syndrome, per site, at five time points to evaluate key domains with a diverse and novel range of methods. This proposal aims to provide a preliminary evaluation to support the enhancement of clinical outcome measures, which ultimately will increase the accuracy in documenting improvements in the lives of children and young adults with Down syndrome.

The objectives of this study are to determine the feasibility and potential efficacy of remotely delivered group exercise sessions to increase daily moderate to vigorous physical activity in adults with Down syndrome, relative to a usual care control. Participants will be randomized to attend 40 min remotely delivered group moderate to vigorous physical activity (MVPA) sessions at low frequency (1 session/wk.,RL), high frequency (3 sessions/wk., RH), or usual care control usual care control (UC). In addition to the group MVPA sessions, participants in both the RL and RH groups will also receive a step counter, access to resources for increasing MVPA, and one 20-min remotely delivered individual support/education session/wk. Content for both the RL and RH arms will be identical with the exception of group session frequency (1 vs. 3/wk.). Participants in the UC arm will receive a step counter, access to resources for increasing MVPA, and monthly remote individual support/education).The primary aim is to Assess daily MVPA (min) in the RL, RH, and UC arms at baseline, 3, 6, 9, and 12 mos., and obtain effect sizes for change in MVPA over 12-mos.Secondary Aim 1 is to assess the impact of MVPA on cardiovascular fitness, quality of life, cognitive function, and brain parameters related to Alzheimer's Disease (whole and regional brain volume, functional connectivity, and cerebral blood flow) at baseline, 6, and 12 mos. Secondary Aim 2 will determine the feasibility (retention, session attendance, use of recorded sessions (RH/RL only) of RL, RH, and UC interventions.

Interventional, comparative, open label, single-center study to demonstrate that an early (from 6 months of age) and systematic (every 6 months) screening of Obstructive Sleep Apnea (OSA) by polysomnography (PSG) in children with Down Syndrome during the first 3 years of life is associated with an improved neurocognitive development at the age of 3 years.
