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 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 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. Braak Hypothesis A German pathologist, Hideo Braak, and his colleagues, conducted an extensive and detailed study of the progression of Lewy body pathology in Parkinson disease.14’15 Theydemonstrated that the pathology of Parkinson disease beginsnot in the motor centers of the brain but in the lower brainstem. De stadiëring van de ziekte van Parkinson werd voor het eerst beschreven door Heiko Braak in 2003.

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 2007, Braak and co-authors advanced a ‘dual-hit hypothesis ’ about the pathogenesis of idiopathic Parkinson's disease, according to which an unknown pathogen akin to a slow-virus may enter the nervous system through both the nasal and intestinal mucosae, eventually resulting in a cascade of neurodegenerative events in the brain.

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 (31), and they presented an associ-ated staging system for PD based on a specific pattern of αSyn spreading (32). These publications were followed by the more Heiko Braak ist ein deutscher Anatom mit dem Forschungsschwerpunkt Klinische Neuroanatomie.
