Which of the following is a key feature of Alzheimer's disease biomarkers?
- They primarily rely on the presence of symptoms for diagnosis
- They are only detectable in the later stages of the disease
- They have low sensitivity and specificity in distinguishing AD from dementia
- They can be used to diagnose Alzheimer's disease in the early stage (correct)
What is the role of amyloid beta (Aβ) in Alzheimer's disease diagnosis?
What is the role of amyloid beta (Aβ) in Alzheimer's disease diagnosis?
- It is a good indicator of AD disease (correct)
