Aphasia Datasets

CATs aims to collate data from completed aphasia trials in stroke, and make these anonymised data accessible to the wider scientific community for exploratory analyses. 

To date we have amassed data on more than 600 individual patients with aphasia following stroke. 

To access these data, please complete a Data Request Form for review by our Management Committee and Steering Group. 


If you have aphasia trial data on:

  • at least 10 individual participants
  • with documentation of time between stroke and aphasia assessments
  • aphasia assessments carried out over at least two time points

why not consider contributing data to the Collaboration of Aphasia Trialists?
