Retinas: New potential clues in diagnosing, treating Alzheimer's

New Delhi, Nov 19 (ANI): A study led by the Cedars-Sinai Department of Neurosurgery has identified certain regions in the retina - the lining found in the back of the eye - that are more affected by Alzheimer's disease than other areas. The findings may help physicians predict changes in the brain as well as cognitive deterioration, even for patients experiencing the earliest signs of mild impairment. "These clues can occur very early on in the progression of Alzheimer's disease - several decades before symptoms appear," said Maya Koronyo-Hamaoui, Ph.D., associate professor of Neurosurgery and Biomedical Sciences and co-corresponding author of the study. The findings of the new study, published in the journal Alzheimer's and Dementia: Diagnosis, Assessment and Disease Monitoring, were from a clinical trial involving people older than 40 who were showing signs of cognitive decline. In the trial, investigators used a non-invasive technique known as sectoral retinal amyloid imaging to ca
