AI Uses Retinal Images to Detect Cognitive Impairment
Researchers have developed a machine learning model that uses retinal images to distinguish normal cognitive function from mild cognitive impairment, potentially detecting early signs of cognitive decline that could lead to Alzheimer's disease. The model shows a sensitivity of 79% and specificity of 83% in identifying individuals with mild cognitive impairment. This non-invasive and cost-effective method could aid in early detection and intervention for cognitive impairment before it progresses to Alzheimer's dementia.
