CDE Catalog | NINDS Common Data Elements

***Please contact the NINDS CDE Team (NINDSCDE@emmes.com) if you encounter any search difficulties.***

The CDE Catalog is a directory of the available NINDS CDEs. Users can search the Catalog to isolate a subset of the CDEs (e.g., all stroke-specific CDEs, etc.), and to view and download details about the CDEs.

Select any filter below to search the CDE Catalog.

For best results, clear form between searches. In addition, when specifying NeuroRehab, Sport-Related Concussion (SRC) or Traumatic Brain Injury (TBI) as the Disease, please select a Subdisease as well.

NeuroRehab Comprehensive includes all NeuroRehab CDE recommendations. NeuroRehab General includes all NeuroRehab CDE recommendations that are not disease specific. All other NeuroRehab Subdiseases include recommendations specific to existing NINDS CDE project disorders.

Choose your Time Frame for your SRC study (Acute (time of injury until 72 hours), Subacute (after 72 hours to 3 months), and Persistent/Chronic (3 months and greater post-concussion) or Comprehensive if your study falls across the study time frames.

Choose your type of TBI study (Acute Hospitalized, Concussion/Mild TBI, Moderate/Severe TBI: Rehabilitation, or Epidemiology) or Comprehensive if your study falls outside of the study types or incorporates aspects of more than one type of study.
