Question

Quizplus · Accepted Answer

The only certain diagnostic test for Alzheimer's disease is an autopsy of the brain. Alzheimer's disease can only be definitively diagnosed postmortem through an examination of the brain tissue to identify the characteristic plaques and tangles. However, there are various diagnostic tests that doctors can use to assess a person's memory, cognitive abilities, brain structure, and genetic risk factors, which can help with early detection and treatment planning. CT scans and MRIs can help identify structural and functional changes in the brain, but they are not definitive for Alzheimer's disease. Blood tests can help rule out other causes of cognitive decline, but they do not confirm Alzheimer's disease.
