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. 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. Several studies have reported that ∼20–50% of PD patients do not conform to the Braak staging scheme [19, 92–94]. The prominent Braak hypothesis postulates that this progression involves spreading Lewy body and neurite pathology from the gut and/or olfactory nerves, with relatively early changes in brainstem structures such as the locus coeruleus, followed by degeneration of the substantia nigra pars compacta leading to the classic movement issues, and

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 A contentious hypothesis about where and how Parkinson’s disease starts off is gaining ground as new studies provide clues in its support. Neuroanatomists Heiko Braak and Kelly Del Tredici, both at the University of Ulm in Germany, have described the distribution of Lewy bodies—the hallmarks of PD pathology—in the central and peripheral nervous systems of deceased patients.

While the Braak model proposes a viral pathogen, a recent study in mice demonstrated that a peripherally administered environmental toxin (i.e. rotenone) may induce a Braak-like spread of αsyn pathology in the CNS . The Braak hypothesis of Lewy pathology progression in Parkinson's disease proposes a systematic spread of α-synuclein that can be staged, … Parkinson's disease is a progressive neurodegenerative disorder with multiple factors contributing to increasing severity of pathology in specific brain regions.

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 Abstract. Sporadic Parkinson’s disease involves multiple neuronal systems and results from changes developing in a few susceptible types of nerve cells. Essential for neuropathological diagnosis are α-synuclein-immunopositive Lewy neurites and Lewy bodies. The pathological process targets specific induction sites: lesions initially occur in the Review: Parkinson’s disease: a dual-hit hypothesis.
