Question

Quizplus · Accepted Answer

The definitive diagnosis of neurocognitive disorder due to Alzheimer's disease can currently only be made based on autopsy results, which reveal the presence of abnormal proteins (beta-amyloid plaques and Tau tangles) in the brain. Cognitive testing and brain scans can provide supporting evidence, but they cannot definitively diagnose Alzheimer's disease. Behavioral analysis may also provide supportive evidence but it is not enough to make the definitive diagnosis.
