Neurologist Questions Alzheimer's Disease

What are the markers of Alzheimer's disease?

My mom is going to get a brain scan to see if she has Alzheimer's disease, since she failed her memory test with her neurologist. She's only 58 years old. What are the markers of Alzheimer's disease? How will they identify it in the scan?

Among the group of potentially useful biomarkers are those that measure changes in the cerebrospinal fluid (CSF) levels of a 42-amino acid form of Aβ, total tau protein, and phosphorylated tau at residue 181.
