Staging of Lewy pathology according to the Braak model. Schematic summarizing the progression of Parkinson’s disease as proposed by Braak and colleagues . 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).

Furthermore, the Braak hypothesis led to the application of a 'prion-like' theory to Parkinson's disease -- purporting that alpha-synuclein aggregates propagate and move from nerve cell to nerve cell, spreading disease, rather than arising organically 2017-02-13 · There has been criticism to Braak's hypothesis, in part because not all patients follow the proposed staging system. Here, we review literature that either supports or criticizes Braak's hypothesis, focused on the enteric route, digestive problems in patients, the spread of LP on a tissue and a cellular level, and the toxicity of the protein αSynuclein (αSyn), which is the major constituent A recent staging procedure for the inclusion body pathology associated with PD proposes that, in the brain, the pathological process (formation of proteinaceous intraneuronal Lewy bodies and Lewy neurites) begins at two sites and continues in a topographically predictable sequence in six stages, during which components of the olfactory, autonomic, limbic, and somatomotor systems become Braak’s Hypothesis. 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 ().

4 Note that, because dementia is included in the definition of DLB, cases of brainstem‐type DLB (low Braak stage DLB) can exist (Fig. 1). 44 Braak's PD staging led to a hypothesis that Lewy pathology spreads along neuroanatomical [Braak's hypothesis and non-motor symptoms of Parkinson disease]. [Article in Japanese] Saito Y(1), Murayama S. Author information: (1)Department of Pathology and Laboratory Medicine, National Center for Neurology and Psychiatry Hospital, Kodaira-shi, Tokyo, Japan. The aim of this study was to determine the interaction between cerebral amyloid angiopathy (CAA) and Braak staging on cognition in the elderly. The study used a total of 141 subjects consisting of 72 non-cognitively impaired (NCI), 33 mild cognitive impairment (MCI), 36 Alzheimer’s disease (AD) cases displaying Braak stages 0-II and III from the Rush Religious Order Study cohort.

Microglial activation as detected by PET has been seen in the cerebral cortex prior to dementia in early PD, suggesting a Braak level 5 or 6 at that early stage. Braak staging suggests that the serotonergic and noradrenergic systems could become dysfunctional ahead of the dopaminergic system in PD.
