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.

2022 Alzheimer’s disease facts and figures

The Alzheimer’s Association has released its 2022 Alzheimer’s Disease Facts and Figures report.

This year, the Alzheimer’s Association is taking a closer look at Mild Cognitive Impairment (MCI) and encouraging greater awareness and understanding of this condition and its relation to Alzheimer’s disease.

Here are some of the top takeaways:

  • More than 6 million Americans are living with Alzheimer’s
  • 1 in 3 seniors dies with Alzheimer’s or another dementia
  • In 2020, COVID-19 contributed to a 17% increase in Alzheimer’s and dementia deaths
  • More than 11 million Americans provide unpaid care for people with Alzheimer’s or other dementias and in 2021, these caregivers provided more than 16 billion hours of care valued at nearly $272 billion.
  • Fewer than 1 in 5 Americans are familiar with mild cognitive impairment (MCI), which can be an early stage of Alzheimer’s
  • About one-third of people with MCI due to Alzheimer’s disease develop dementia within 5 years of diagnosis
