-The diagnosis of Alzheimer'​s Disease remains a clinical diagnosis, though neuroimaging and biomarkers are beginning to play a larger role in diagnosis. Amyloid-based diagnostic tests such as amyloid imaging on brain positron emission tomography (PET) scans and measuring amyloid beta-42 (look for reduced levels) in the [[neurology:​investigations:​lp|cerebrospinal fluid]] (CSF) may sometimes be helpful. Signs of neuronal injury, such as hippocampal and temporoparietal cortical atrophy on a MRI or temporoparietal hypometabolism on a fluorodeoxyglucose PET scan may provide non-specific evidence for AD.+The diagnosis of Alzheimer'​s Disease remains a clinical diagnosis, though neuroimaging and biomarkers are beginning to play a larger role in diagnosis.
