Putting the New Alzheimer Disease Amyloid, Tau, Neurodegeneration Diagnostic System to the Test
The field of neurodegenerative dementias, particularly Alzheimer disease (AD), has been limited by challenges in accurate diagnosis, but has recently been potentially revolutionized by the development of imaging and cerebrospinal fluid (CSF) biomarkers. These biomarkers have influenced the diagnostic evaluation of symptomatic patients with cognitive impairment or dementia, particularly in dementia subspecialty practice. The primary biomarker modalities include magnetic resonance imaging (MRI), positron emission tomography (PET), and CSF.
