There are currently four main Cohort tools: the Cohort Directory and Cohort Matrix (found on the DPUK website); the Comparison tool; and the Cohort description page found in the DPUK Data Portal. Explanations and user notes are provided for each of these tools. Click here for the DPUK Cohort Tools and Registration Guide.
Which tool(s) you may find useful, and in what order, depends on what information you’re looking for. Some examples are:

  • You know what topics you are interested in and want to know which cohorts, if any, might have relevant data? Then start with the Cohort Matrix to get a list, then either use the Comparison tool to get more detailed information or jump straight to the Cohort description page to see if those are the cohorts for your study.
  • You’ve already got cohorts in mind but want to see what similar cohorts there are? Use the Cohort Matrix and/or Comparison tool.
  • You already know which cohorts you want to use and now need detailed information? Jump straight to the Cohort description page(s) found through the Comparison tool.

DPUK would like to thank all Cohort teams for giving their time and sharing their information in order to create these tools.


We are pleased to introduce the DPUK Cohort Directory which forms a key part of the Platform by bringing together information from our existing UK cohort partners. The aim of this directory is to highlight the broad scope of information from studies that are already underway. Our cohorts represent research from across the dementias, including Alzheimer’s disease and Parkinson’s disease, as well as from the general population. The Directory will also showcase a broad range of study methods, from questionnaires to intensive biological investigations, across a wide age range.

The information included in the Cohort Directory provides a high level overview of the cohort profile and type of variables and data collected, based on the MRC Cohort Directory. As new cohorts join the Platform their information will be added here.

Please find our Cohort Directory below.



The Cohort Matrix allows you to quickly identify which cohort might hold information you’re interested in for your research project.

The first 4 columns are fixed and relate to general cohort demographics. The other columns are topic headings from the Cohort Finder. Use the scrollbar at the bottom of the screen to show more columns.

A tick in the column means that the cohort collects some sort of information on that topic (it doesn’t specify the quality of the data), while a cross means that no information on that topic is collected.

Clicking on the column header, e.g. COGNITION, will filter the list to only show those cohorts which collect some form of cognition data. Clicking on the cohort name down the left-hand side will filter the list to show cohorts which collect information on similar topics. So, if you want to increase your study population, you could start by looking at similar cohorts to the one(s) you’re interested in.

Remember to click the RESET FILTER button at the bottom of the screen after you’ve filtered the cohort list. Otherwise, you might accidentally be searching a subset of cohorts.
