Question

Quizplus · Accepted Answer

Autopsy is currently the only way to definitively diagnose Alzheimer's disease dementia, as it involves examining the brain tissue for the presence of abnormal protein deposits known as amyloid plaques and tau tangles, which are hallmarks of the disease. Psychological testing and mental status exams can provide supportive evidence for a diagnosis, but they cannot confirm it. Reported observations by family members can also be helpful in identifying symptoms and changes in behavior, but they cannot provide a definitive diagnosis.
