Researchers have identified that an eye condition affecting the retina, the light-sensing tissue in the back of the eye, may serve as an early indicator for Alzheimer’s disease.<\/p>\n

Their findings offer new insights into the potential use of retinal changes as early biomarkers for Alzheimer’s, which could improve diagnosis<\/a> and treatment of neurodegenerative disease.<\/p>\n

The new findings indicate that the presence of the APOE4 gene\u2014known to increase the risk of Alzheimer’s disease in humans\u2014in mice impairs retinal function, suggesting a direct link between this genetic variant and visual processing deficits associated with Alzheimer’s disease.<\/p>\n

“The eye is a window to the brain reflecting changes associated with neurodegenerative conditions such as Alzheimer’s disease,” says Ashay Bhatwadekar, associate professor of ophthalmology and principal investigator of the study.<\/p>\n

“Nearly 7 million Americans are living with Alzheimer’s disease, and our study will help provide ease of diagnosis and potential intervention for Alzheimer’s disease, thus enhancing patient outcomes and quality of life<\/a> in the future.”<\/p>\n

The research team used advanced imaging techniques to assess retinal structure and function in the mice. Compared to control groups, they observed significant alterations in retinal thickness and electrical activity in biological tissues and cells.<\/p>\n

These findings align with clinical observations of retinal abnormalities in Alzheimer’s patients, reinforcing the relevance of this model for studying triggers of the disease.<\/p>\n

“Our study demonstrates that retinal dysfunction occurs in the APOE4 mouse model, mirroring aspects of Alzheimer’s pathology,” says PhD student Surabhi D. Abhyankar.<\/p>\n

“These results underscore the potential of retinal imaging as a non-invasive method to detect early neural changes in Alzheimer’s disease.”<\/p>\n

The research appears in Alzheimer’s & Dementia<\/em><\/a>. Additional researchers are from Indiana University, the Stark Neurosciences Research Institute, and the University of Toronto.<\/p>\n

Support for this research came from the National Eye Institute and Research to Prevent Blindness.<\/p>\n
