Question

Quizplus · Accepted Answer

Alzheimer's disease can only be diagnosed through exclusion, which involves ruling out all other causes of dementia before concluding that Alzheimer's is the cause. Magnetic resonance imaging (MRI) or computed tomography (CT) scans can show changes in the structure of the brain with Alzheimer's, but these can also be present with other types of dementia. Neurological tests may indicate specific symptoms, but they cannot definitively diagnose Alzheimer's disease. PET scans may show how the brain and its tissues are working, but they are not required for a diagnosis of Alzheimer's.
