Confirmatory Clinical Trial for Verifying the Efficacy and Safety of 'ALZGUARD' as a Digital Dementia Diagnostic Aid-Tool for the Diagnosis of the Major Neurocognitive Disorders

The study will be conducted across multiple sites, enrolling participants aged 55 to 85 years olds. The primary objective of the study is to compare the diagnositic accuracy of ALZGAURD against traditional diagnostic evaluactions conducted by medical professionals. The primary endpoint for efficacy will be the Area Under the Curve(AUC), which will measure the diagnostic performance of the application. This statistical metric will help determine how well ALZGUARD can identify dementia compared to standard diagnostic methods.
