Dr. Dickson uses the Braak staging method, defined by German anatomist Heiko Braak in 2991. That staging method in AD is found in this important paper: “Neuropathological stageing of Alzheimer-related changes” Braak, H.; Braak, E. Acta Neuropathologica. 82 (4): 239–59. 1991.

E . Frequency of stages of Alzheimer-related lesions in different age Reimagining Alzheimer's disease-an age-based hypothesis. Braak stages I and II are used when neurofibrillary tangle involvement is confined mainly to the transentorhinal region of the brain, stages III and IV when there is with the fact that the motor symptoms that lead to a diagnosis of PD are due to loss of dopamine neurons. The later Braak stages (4-6) involve the supratentorial This critical review highlights major landmarks, hypotheses and controversies fit this staged progression of the disease, according to Braak's hypothesis, some 22 Apr 2014 The Braak hypothesis, which revolutionized how researchers think about Parkinson's disease, posits that alpha-synuclein aggregation could Braak Staging and Prion-Like Spreading Hypothesis.

According to the Braak model, αsyn deposits in specific brain regions and neuronal types giving rise to Lewy pathology in a stereotypic, temporal pattern that ascends caudo-rostrally from the lower brainstem (including the dorsal motor nucleus of the vagus nerve in the medulla then the coeruleus-subcoeruleus complex, raphe nuclei Although Braak and his colleagues did not reveal a relationship between Braak stage and the clinical scores, their hypothesis indicated that the toxic oligomeric variety of α-synuclein is able to spread cellularly from the enteric and olfactory system to the higher brain regions where it can provoke a vicious circle of neuroinflammation (Burke et al., 2008). 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's hypothesis states that sporadic PD is caused by a pathogen that enters the body via the nasal cavity, and subsequently is swallowed and reaches the gut, initiating Lewy pathology (LP) in the nose and the digestive tract.

This comes out of some research into surgeries done on the vagal nerve, which runs from the brainstem to the abdomen. Vagotomies were formerly performed to treat peptic ulcers. Skepticism concerning the dual-hit hypothesis and the Braak staging system derives in part from a number of discrepant findings in the neuropathology literature.

In 2003, Braak et al. postulated the hypothesis that an unknown pathogen (virus or bacterium) in the gut could be responsible for the initiation of sporadic PD (), and they presented an associated staging system for PD based on a specific pattern of αSyn spreading ().

19 Jun 2019 These results conform with Braak's staging hypothesis, areas that are hypothesised to underlie pre-symptomatic disease (Braak stages 1–3). The six stages of the Braak staging concept for Parkinson's disease infected by one after the other supports the hypothesis that the pathology develops in a 2 Feb 2021 Many of these models take advantage of the prion hypothesis which asserts that the progression of proteopathy, in AD, follows from a prion-like 30 Oct 2019 Once the pathology has spread and inflicted sufficient damage to the pons (Braak stage II), RBD emerges.
