Official title

Evaluating Cognitive Outcomes in Down Syndrome-2

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
