Down syndrome occurs when a person is born with an extra copy of chromosome 21. It affects about 1 in 700 babies in the United States and causes developmental delays, characteristic physical features, and increased risk for heart defects, leukemia, and Alzheimer's disease. Treatment focuses on early intervention, managing health conditions, and supporting development.
What's actually going on in research
Trials are testing drugs that may improve cognitive function, including GABA antagonists and green tea extract. Researchers are studying heart defects, leukemia treatment modifications, early-onset Alzheimer's, and immune system differences. Many studies focus on understanding how the extra chromosome affects different body systems and whether targeted treatments can address specific challenges.
Cognitive enhancement drugs
Several trials are testing whether drugs targeting GABA receptors or other brain pathways can improve memory and learning in people with Down syndrome. Some focus on children during critical developmental windows, others on adults at risk for Alzheimer's.
Alzheimer's prevention
Most adults with Down syndrome develop Alzheimer's disease by their 60s. Studies are testing whether drugs that work in the general population might delay or prevent dementia in people with Down syndrome.
Leukemia treatment refinement
Children with Down syndrome have higher leukemia cure rates but also more treatment complications. Trials are testing whether adjusted chemotherapy doses can maintain high cure rates while reducing side effects.
What to know before you search
Eligibility varies widely by study type but may depend on age, cognitive level, specific health conditions like heart defects or leukemia history, and whether the person has signs of Alzheimer's disease.
What types of trials are currently open
- Cognitive trials — Testing whether drugs or supplements can improve memory, learning, or language in children or adults with Down syndrome.
- Alzheimer's prevention trials — Testing drugs that may delay or prevent dementia in adults with Down syndrome, who are at very high risk.
- Cancer treatment trials — Studies refining chemotherapy doses for children with Down syndrome and leukemia to balance cure rates with reduced side effects.
- Heart health studies — Research on preventing and treating heart defects, which affect about half of babies born with Down syndrome.
- Natural history studies — Following people with Down syndrome over time to understand health patterns, aging, and what factors predict better outcomes.
Recently added Down Syndrome trials
Try sensory activities designed to improve movement and balance
To investigate the effect of sensory integration on gross motor function in children with Down syndrome. To investigate the effect of sensory integration on balance in children with Down syndrome.
Donate a blood sample to help validate a new prenatal screening test
The goal of the ADVANCE (Assay Development and Validation for Pre-Natal and Obstetric Conditions) study is to compare the concordance of results of a novel non-invasive circulating fetal cell (CFC) assay to the results of prenatal invasive diagnostic testing or postnatal genetic and clinical diagnosis of the resulting neonate. This is a prospective study of pregnant individuals.
