WebJan 21, 2024 · Tau PET scans detect the abnormal accumulation of the tau protein. Tau forms tangles within nerve cells in Alzheimer's disease and many other dementias. Tau PET scans may be used by doctors to monitor progression of Alzheimer's, but they are not commonly used in standard medical practice. WebMar 9, 2015 · Pathophysiology of Tau in AD Tau proteins result from a single microtubule-associated protein tau (MAPT) gene (chromosome 17q21) in humans and were discovered in 1975. Healthy neurons contain microtubules, which serve as a support structure and guide nutritional supplies.
