The PORCH study collects cognitive, behavioral, physiological, biofluids, and neuroimaging data from study participants to understand the epidemiology and risk factors of Alzheimer’s dementia in midlife. The study consists of a well-characterized population sample and provides various avenues for collaboration with external investigators on funded research studies and funding applications.
The PORCH study shares custom datasets, and in some circumstances conducts data analyses as part of funded research collaborations. In these collaborations, PORCH study designated investigator(s), who understand the study design and provide appropriate areas of expertise.

The PORCH Research Steering Committee will review your request based on a brief concept proposal and a decision for approval will be made. If your concept proposal is approved, your will work with one of the committee members to develop a full, more detailed proposal for review and approval. Interested investigators must obtain PORCH Steering Committee approval of their idea for research collaboration. Requests for custom PORCH datasets or analysis must meet these conditions:

Timeline from submitting a proposal to receiving the data or analysis results
The timeline varies depending on funding, the grant timeline, and staff availability. In general, it takes about 3-6 months to provide data or analysis results after a project begins, depending on complexity. Projects with ongoing planned collaboration will set their own timeline.
