New Delhi, Mar 15: A revolutionary artificial intelligence (AI)-driven system developed by US researchers is poised to transform the early detection of cognitive impairments, potentially mitigating the devastating effects of Alzheimer’s disease and other forms of dementia in older adults.
The system, designed by a team at the University of Missouri, targets mild cognitive impairment (MCI), often a precursor to Alzheimer’s and dementia. Early detection of MCI is crucial for effective interventions and improved patient outcomes, but traditional diagnostic methods can be complex, time-consuming, and inaccessible, particularly in rural areas.
This innovative system utilizes a portable assessment device equipped with a depth camera, force plate, and interface board. It measures various aspects of motor function, which are intricately linked to cognitive health. Researchers conducted studies involving older adults, including those with MCI, asking them to perform three tasks: standing still, walking, and standing up from a bench. To increase cognitive load, participants were required to count backward in intervals of seven while performing these tasks.
The device recorded their movements, and the data was subsequently analyzed using a sophisticated machine learning model, a form of AI, specifically trained to identify cognitive impairment. The system achieved an impressive 83% accuracy in detecting MCI, demonstrating its significant potential as a diagnostic tool.
“The areas of the brain responsible for cognitive function also influence motor abilities such as balance and walking,” explained Trent Guess, an associate professor in the College of Health Sciences at the University of Missouri. “Our device can detect subtle changes that might go unnoticed through standard observation.”
As the global prevalence of Alzheimer’s disease continues to rise, this portable AI system offers a promising avenue for early detection, enabling timely interventions to slow cognitive decline.
Beyond Alzheimer’s, researchers envision a wide range of applications for this technology, including concussion assessments, sports rehabilitation, monitoring patients with ALS and Parkinson’s disease, and post-surgical recovery for knee and hip replacements.
By leveraging the connection between motor function and cognitive health, this AI-powered device holds the potential to revolutionize neurological care and improve the lives of millions worldwide.
Disclaimer: It is important to note that while this AI-powered system shows promising results, it is still under development and further research is necessary to validate its effectiveness and clinical utility.
