All pretangle Stage a and Stage b cases exhibited AT8-ir material in the locus coeruleus in the absence of lesions in the anteromedial temporal cortex. Notably, none of these cases had isolated tau-ir neurons in any other subcortical nuclei with diffuse projections to the cerebral cortex (Table, Supplemental Digital Content 1, Supplementary Data ).

The pivotal 1991 study by Heiko Braak and Eva Braak did just that (Braak and Braak, 1991). It showed that tau inclusions form in a stereotypical fashion, allowing classification depending on where the inclusions are found and in what number.

Abstract on PubMed (ID# 1759558) Braak staging in AD has six A system formulated in 1991 by Drs. Braak and Braak (Acta Neuropathologica Berl—82:239-259) for staging the severity of Alzheimer’s disease (AD), based on the premise that AD pathology—specifically neurofibrillary tangles—evolve in stages and locations, beginning in the mesial temporal lobe (stages 1 and 2) and extending to the limbic regions (stages 3 and 4)—at which point dementia manifests itself clinically—ending in the neocortex (stages 5 and 6).

Braak staging refers to two methods used to classify the degree of pathology in Parkinson's disease and Alzheimer's disease. These methods are used both in research and for the clinical diagnosis of these diseases and are obtained by performing an autopsy of the brain.

J Neuropathol Exp Neurol 49:215–224 Where Schöll defined three large ROIs to tau staging, Schwarz chose six, one for each individual Braak stage. He chose cutoffs for each region that exceeded the uptake level he saw in young healthy controls. Schwarz found that his in vivo staging largely matched that expected for each person’s clinical profile. The islands are clearly revealed by staining for the mitochondrial enzyme cytochrome oxidase (28).

The Braak system was based upon assessment of two 100 μm sections processed according to the silver-iodate technique proposed by Gallyas [49–51, 67, 68, 78].

The neuropathological staging model proposed by Braak and Braak (1991) implies that the evolution of neurofibrillary pathology follows a predictable sequence and can be ordered in a regular regional hierarchy. A total of 42 cases of an elderly population sample, which had been prospectively clinically assessed, were examined.
