An Alzheimer-detection technology developed by 茄子直播 startup company Winterlight Labs has won the AGE-WELL Pitch Competition: Technology to Support People with Dementia, beating competitors from across the country and internationally.

The new tablet-based assessment tool records short samples of a person鈥檚 speech as they describe a picture on the screen. It extracts hundreds of variables from the samples, producing results in less than five minutes.

Winterlight Labs has its origins in the computer science department at the University of Toronto. CEO Liam Kaufman holds both a degree in computer science and a master鈥檚 degree from 茄子直播鈥檚 Institute of Medical Science. Co-founder Katie Fraser is a PhD student in computer science. Master鈥檚 student Maria Yancheva and computer science assistant professor Frank Rudzicz also worked on the application.

鈥淪peech is a rich source of information on people鈥檚 cognitive health,鈥 Kaufman told a panel of expert judges at the AGE-WELL Pitch Competition on July 23 in Toronto. 鈥淏ecause of word-finding difficulties, people with Alzheimer鈥檚 disease will tend to pause more between words and the complexity of their vocabulary is reduced, so they will use a word such as 鈥榗ar鈥 instead of 鈥楽UV鈥 or 鈥榮edan.鈥欌

The new technology uses artificial intelligence to analyze about 400 variables, such as pitch, tone, prosody (rhythm), and rate of speech, as well as pauses and choice of words. In the laboratory, the software can reliably identify Alzheimer鈥檚 disease, Parkinson鈥檚 disease and aphasia with between 85 and 100 percent accuracy.

The Winterlight approach is fast and objective, and improves on time-consuming 鈥榩encil-and-paper鈥 neuro-psychological assessments, which can be stressful for people with memory problems, he said.

The researchers are set to begin field tests in assisted living and home care settings, with funding from AGE-WELL. Five organizations which collectively care for more than 100,000 seniors are partnering with Winterlight Labs.

The tool will be used in seniors鈥 facilities to improve ongoing monitoring of residents鈥 cognitive health, provide family members with quantifiable updates and help everyone plan when it鈥檚 time to transition to a higher level of care, said Kaufman.

Regulatory approval will be sought in Canada and the United States to make the technology available to family doctors and speech-language pathologists.

鈥淭he incidence of Alzheimer鈥檚 disease and other dementias is growing worldwide, and new technologies like this novel speech-assessment tool present a real opportunity to help people with dementia and those who care for them,鈥 said Alex Mihailidis, AGE-WELL鈥檚 scientific director.
