About the project

Computational Assessment of Stroke Survivors (COMPASS)

Stroke affects 152,000 UK citizens every year. Over 50% of stroke survivors have cognitive impairment. Currently, 850,000 people live with dementia in the UK and stroke is one of the biggest risk factors.

However, current pen-and-paper based tests are not always appropriate for stroke survivors who often have motor, visual or language difficulties. In addition, longitudinal follow-up is required to detect emerging cognitive impairment. Assessments typically take place in hospital settings, are costly and often inconvenient for patients.

This project aims to create an easy-to-use cognitive assessment tool specifically designed for the needs of stroke survivors. It will be based on our stratification tool COCOA (computational cognitive assessment), developed for detecting early signs of dementia. The tool uses automatic analysis of conversations that patients have with an on-screen digital doctor.
