In 2012, a new technology became available that allows doctors to diagnose Alzheimer's disease based on ________associated with the disease together with clinical evidence of memory loss.
A) examination of glucose levels
B) brain scans showing plaques
C) a complete review of behavioral and neuromuscular deficits
D) inspection of brain tissue by a biopsy or autopsy

Question

Quizplus · Accepted Answer

The new technology referred to in the question is most likely positron emission tomography (PET) scans that can detect the presence of beta-amyloid plaques in the brain, which are a hallmark of Alzheimer's disease. These scans can be used in combination with clinical evidence of memory loss to make a diagnosis of Alzheimer's disease. A is incorrect because glucose levels are not directly associated with Alzheimer's disease. C is incorrect because while behavioral and neuromuscular deficits are commonly seen in patients with Alzheimer's disease, they are not sufficient for a definitive diagnosis. D is incorrect because a biopsy or autopsy is not a viable diagnostic tool during the early stages of Alzheimer's disease.
