Cognitive tests designed and validated for seniors and patients
This platform offers validated cognitive tasks that evaluate different cognitive functions, primarily memory. We are a team of neurologists and cognitive scientists from University of Oxford, who developed these tasks for academic use and keep refining them based on feedback from our projects. Please click the icons below to try the task on tablet or computer. Phone version is also available. Please contact us if you need it.
News & Publications
- We are pleased to announce that the first comprehensive methods paper for the OCTAL is now available as a preprint on medRxiv. This publication represents the culmination of four years of dedicated work. Thanks to everyone who contributed to the development of OCTAL and the recruitment of participants. The preprint can be accessed here: https://www.medrxiv.org/content/10.1101/2025.06.23.25330153v1
- OCTAL, taken remotely on a tablet, demonstrates outstanding accuracy in identifying individuals with Alzheimer’s disease based on their performance. [Toniolo, Zhao et al. 2024 Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring]
- Alzheimer’s patients can conveniently complete OCTAL on their tablets at home. Their performance strongly correlates with key Alzheimer’s blood biomarkers, especially phosphorylated tau 181. [Toniolo, Zhao et al. 2024 Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring]
- We discovered that long-COVID patients have severe cognitive slowing, which is evident by their significantly slow reaction time, using a 30-second Simple Reaction Time task. On contrast, people who infected COVID-19 had normal response speed. [Zhao et al. 2024 eClinicalMedicine]
- Young people who contracted COVID-19 showed a minor attention deficit. [Zhao et al. 2022 Brain Communications]
