The primary objective is to characterize trajectories of change on the primary outcome measures in this study population through longitudinal collection of measures of cognition, function, behavior, and health status.

Official Title

The Down Syndrome Clinical Trials Network (DS-CTN) Study of Alzheimer's Disease in Down Syndrome


The DS-CTN will engage in rigorous, high quality research to better understand AD-DS and the medical needs of this population. The LIFE-DSR study will utilize the DS-CTN network to achieve these goals through evidence-based research and a combination of proven and novel methodologies. The network will initially recruit and employ experts and clinical trial sites who have access to adults with DS and whose focus is on AD-DS.

This trial also aims to develop sensitive and well-validated assessment instruments of cognition, behavior and function appropriate for future clinical trials directed at AD-DS in adults with DS ages 25 and older.

In addition, this LIFE-DSR study will serve as a parent protocol that includes one or more sub-studies, each of which has its own protocol and consent form. These sub-studies will recruit from eligible participants enrolled in this LIFE-DSR protocol.
