Using Smartwatches to Track Brain Health: A New Approach

If your smartwatch could help detect early signs of cognitive decline. Researchers are exploring a new way to monitor brain health using a simple task called the n-back test, delivered through smartwatches. This test, known for assessing working memory, is being used to gather real-time data about cognitive function in everyday environments. The study aims to check if this method is practical, consistent, and accurate for people at different stages of cognitive health. Instead of traditional testing in a lab, participants will use their smartwatches to complete the n-back task whenever they receive a prompt. This way, researchers can gather information about people's cognitive abilities in their natural settings. The n-back test is straightforward. It involves remembering a sequence of items, like numbers or letters, and comparing them to what was shown earlier. The smartwatch version of this test is designed to be user-friendly and quick, making it easy for people to participate. By using smartwatches, researchers hope to gain a more comprehensive understanding of how cognitive abilities vary throughout the day and in different situations. This could lead to earlier detection of cognitive decline and better strategies for supporting brain health. However, there are challenges to consider. Smartwatches might not be accessible to everyone, especially older adults who may not be comfortable with technology. Additionally, the accuracy of the data collected depends on how well participants engage with the test. In the end, this innovative approach offers a promising way to track brain health in real-time. It encourages us to think about how technology can play a role in monitoring and maintaining our cognitive well-being.
