Summary: A congenital condition known as Down syndrome is typified by an excess of genetic material from chromosome 21, making 47 chromosomes in total. Development of the body and brain may be impacted. About 1 in 700-1100 live births have the condition, and 1 in 700-1100 live births inherit it. Heart disease, hypotonia, ligament laxity, cerebral disabilities, thyroid abnormalities, and metabolic diseases ...

Summary: This study aims to use clinical and biological characteristics of acute leukemias to screen for patient eligibility for available pediatric leukemia sub-trials. Testing bone marrow and blood from patients with leukemia that has come back after treatment or is difficult to treat may provide information about the patient's leukemia that is important when deciding how to best treat it, and may help d...

Summary: This study attempts to learn more about the health of persons with Down syndrome after treatment for acute leukemia. Children with Down syndrome are at increased risk for side effects during treatment for acute leukemia, but it is unclear of their risk for long-term effects of cancer treatment. By learning more about the factors that may contribute to chronic health conditions and long-term effect...

Summary: The purpose of this study is to determine efficacy of guanfacine immediate release (GIR) for the treatment of hyperactivity/impulsivity and inattention in children 6-12 years of age with Down syndrome (DS) after 8 weeks of treatment.

Summary: The purpose of this study is to assess whether oxygen supplementation during sleep improves working memory and other clinical and patient-reported outcomes among children who have Down Syndrome (DS) with moderate to severe Obstructive Sleep Apnea (OSA).

Summary: The goal of this study is to develop a registry for Down syndrome (DS) to facilitate research participation by individuals with Down syndrome. DS-Connect® is an online survey tool designed to collect demographic data and health information from individuals with DS. It is open to all people with Down syndrome. The purposes of DS-Connect® are: 1. To identify the various phenotypic manifestations of ...

Summary: 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 neurod...

Summary: The primary purpose of this study is to evaluate the safety and tolerability of ION269 in adults with Down syndrome with evidence of brain amyloid positivity.

Summary: Children with Down syndrome (DS) have a 3-5 time greater prevalence of Attention Deficit Hyperactivity Disorder (ADHD) than typically developing (TD) children. Despite this higher risk of ADHD, rates of stimulant medication treatment are disproportionately low in children with DS+ADHD, even though stimulants are the most efficacious ADHD treatment and are recommended by consensus guidelines for us...

Summary: Down Syndrome (DS), a genetic condition marked by the presence of an extra chromosome 21, is associated with various cognitive and physical challenges. Children with DS often experience motor development issues, including reduced endurance and decreased trunk stability, which underscores the need for targeted interventions. Common impairments in individuals with DS include hypotonia, ligament laxi...

Summary: Purpose: Conduct a wait-list randomized controlled trial (RCT) of an inclusive physical activity program called PACE for adults with intellectual disability (ID) who are not yet showing signs of Alzheimer's Disease (AD)/age-related dementias (ARD). Participants: Participants include 120 adults with ID, their caregivers, and their coaches (up to 360 individual participants, grouped as triads), recr...
