Recent research has identified high cholesterol and vision loss as new risk factors for dementia, potentially preventing or delaying nearly half of all cases if addressed early in life. These findings were presented at the Alzheimer's Association International Conference, which also showcased a blood test capable of diagnosing Alzheimer's with 90% accuracy, and promising results from GLP-1 drugs like liraglutide that may slow cognitive decline. Mayo Clinic researchers are utilizing AI to enhance EEG analysis for early dementia detection, making diagnostics more accessible. Additionally, a study linked excess body fat in certain areas to a higher risk of neurodegenerative diseases.
