BDR uses brain wave analysis to accurately detect normal aging, early cognitive impairment, and Alzheimer's disease risk. Through an FDA-approved brain wave collection device, it can collect brain signals in just 5 minutes and combine that with clinical data by AI analysis, provide objective risk assessment, non-invasiveness. This helps identify early-stage neurodegeneration and provides treatment guidance. It can supplement questionnaire-based diagnosis and monitoring, with an accuracy rate of up to 90%.
