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. 2018-07-04 · Braak H, Alafuzoff I, Arzberger T, Kretzschmar H, Del Tredici K (2006) Staging of Alzheimer disease-associated neurofibrillary pathology using paraffin sections and immunocytochemistry.

AB - Parkinson's disease (PD) is a neurodegenerative disorder for which there is no cure. Theory of PD Progression: Braak’s Hypothesis. The current theory (part of the so-called Braak's hypothesis) is that the earliest signs of Parkinson's are found in the enteric nervous system, the medulla and the olfactory bulb, which controls sense of smell. Under this theory, Parkinson's only progresses to the substantia nigra and cortex over W e conclude that Braak ’ s hypothesis and the Braak staging sys-tem are valuable and useful for the fut ure study of PD, a nd these . theories are likely to accurately describe disease The pathological staging postulated by the Braak hypothesis is in good agreement with the fact that these non-motor symptoms precede motor symptoms in PD, because affected brain areas in the early stages, such as dorsal vagal nucleus, locus ceruleus and olfactory bulb, are related to these non-motor features. Keywords: Prion, Parkinson's disease, Braak staging, Alpha synuclein Braak staging of Parkinson’s disease Braak and colleagues devised their widely accepted staging system of PD progression by assessing the regional distri-bution of αsyn immunoreactive structures in the brains of 110 αsyn positive subjects (69 incidental and 41 clinically Braak staging 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 However, it seems to me that the Braak & Del Tredici paper also contains at least one piece of evidence supporting their Staging hypothesis against the new Threshold theory. This comes out of some research into surgeries done on the vagal nerve, which runs from the brainstem to the abdomen.
