Researchers develop tool that uses audio recordings to detect dementia

Researchers have discovered a new way to diagnose dementia, one that could lead to an automated online diagnosis process.

Currently those concerned about memory issues may go through a battery of cognitive tests. Those tests can include identifying images on a card, reciting a list of random items that are spoken aloud and the famous “clock test,” which requires one to draw a clock set at a specific time. These tests are typically done in person, in a clinician’s office.

Researchers from Boston University have developed an automated tool that can detect not only dementia but mild cognitive impairment (MCI) with impressive accuracy. Such a model could offer great benefits, as early detection is key to being able to access early interventions and get people enrolled in clinical trials. Online testing access would be a key benefit in remote areas.

The computational model uses audio recordings of neuropsychological tests to detect cognitive impairment. The model focuses on the content of what is said versus how words are spoken, researchers said. Researchers discovered that the Boston Naming Test, in which individuals are asked to label a picture using a single word, is the most useful for an accurate dementia diagnosis.
