A study involving 8,623 people in England found that loss of visual sensitivity and eye movement issues can predict dementia, including Alzheimer's, up to 12 years before diagnosis, highlighting the potential of eye-based tests for early detection.
A study involving 8,623 participants in Norfolk, England, suggests that a loss of visual sensitivity can predict dementia up to 12 years before diagnosis. The research indicates that visual issues, such as difficulty in recognizing shapes and controlling eye movements, may be early indicators of cognitive decline due to Alzheimer's disease. These findings highlight the potential of vision tests as early diagnostic tools for dementia, although widespread use is limited by the cost and complexity of eye-tracking technology.
Researchers at Weill Cornell Medicine used zebrafish larvae to study how brainstem neurons guide gaze and maintain short-term memory. By mapping neuronal circuits, they developed a computational model that accurately predicted network activity, offering insights into visual-motor systems and potential treatments for eye movement disorders. The study highlights the zebrafish's simple neural anatomy as a valuable model for understanding complex brain functions.
Researchers are developing earpiece microphones, or 'hearables,' to detect early signs of Alzheimer's by monitoring eye movement signals through eardrum vibrations. This noninvasive method offers a cost-effective alternative to conventional eye trackers, potentially enabling long-term monitoring for Alzheimer's and other neurological disorders. The research, led by teams from École de Technologie Supérieure and Dartmouth University, aims to create health-monitoring algorithms for continuous disease detection.
Researchers are exploring a novel method for early Alzheimer's detection by analyzing saccadic eye movements using in-ear microphones. These tiny eye movements, which become sluggish in Alzheimer's patients, can be detected through vibrations in the eardrums. The study, led by teams from École de Technologie Supérieure and Dartmouth College, aims to test this technique on 35 Alzheimer's patients. This approach could lead to a non-invasive, cost-effective diagnostic tool, potentially applicable to other diseases as well.
A study involving 8,623 participants in Norfolk, England, found that a loss of visual sensitivity could predict dementia 12 years before diagnosis. Visual issues may be an early indicator of cognitive decline as toxic amyloid plaques associated with Alzheimer's disease may first affect areas of the brain associated with vision. Deficits in visual processing, such as contrast sensitivity and inhibitory control of eye movements, may also be early signs of Alzheimer's. Eye movement may play a role in memory improvement, but using deficits in eye movements as a diagnostic tool for early-stage Alzheimer's is currently limited by access to expensive and complex eye-tracking technologies.
A new study suggests that a loss of visual sensitivity can predict dementia 12 years before diagnosis, as visual issues may be an early indicator of cognitive decline. Problems with eye movements and processing new faces may also be early signs of Alzheimer's disease. Research is ongoing to determine if deliberate eye movements can improve memory, but access to eye-tracking technologies remains a bottleneck for using eye movements as a diagnostic tool for early-stage Alzheimer’s outside the laboratory.
