Tas Test Paper

Our latest research has us a step closer to developing a computer test that can detect dementia, decades before any memory symptoms emerge.

Tas Test Paper

In 2020, Neurologist Jane Alty and Computer Scientist Quan Bai, along with James Vickers and other members of the ISLAND team, developed TAS Test – a new computer screening test that measures the changes in hand movements that indicate increased risk of dementia occurring 10 - 20 years later. This exciting research was funded through a $900,000 National Health and Medical Research Council grant.

In the latest study, Jane and PhD Student Renjie Li led the research team to analyse the effectiveness of TAS Test with some of you, our ISLAND Project participants. About 400 participants took part in the study, undertaking TAS Test at home, where they recorded themselves tapping their fingers against their thumbs in a quick test that took around 30 seconds. 

The researchers compared precisely measured details of these movements, such as the rhythm of tapping and the speed of the movements, to the participants’ cognitive test scores which were recorded as part of the main ISLAND Project. 

Thank you to everyone who was involved. Another round of TAS Test assessments will be undertaken in June this year. Please keep completing TAS Test each year when you are invited. We need yearly data as this makes TAS Test as accurate as possible.  

The study paper, “Brief webcam test of hand movements predicts episodic memory, executive function, and working memory in a community sample of cognitively asymptomatic older adults,” was led by PhD student Renjie Li and published in Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, a journal of the Alzheimer’s Association
