Question

Quizplus · Accepted Answer

Postmortem autopsy is currently the only definitive diagnostic tool for AD as it provides a thorough examination of brain tissue for characteristic changes associated with the disease. While other diagnostic tests such as EEG, PET scans, and MRIs may be used in conjunction with clinical assessments, they are not conclusive on their own.
