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.
Heiko Braak ist ein deutscher Anatom mit dem Forschungsschwerpunkt Klinische Neuroanatomie. Von 1980 bis 2002 bekleidete er einen Lehrstuhl für Anatomie an der Universität Frankfurt am Main. Nachfolgend beschäftigte er sich in Frankfurt ehrenamtlich mit Fragestellungen zu neurodegenerativen Erkrankungen des Menschen. Seit 2009 ist er Seniorprofessor am Zentrum für Biomedizinische Forschung der Universität Ulm.

Neurobiol Aging 2003; 24: 197–211. 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. 2021-01-21 · Braiding Braak and Braak: Staging patterns and model selection in network neurodegeneration Prama Putra, Travis Thompson, and Alain Goriely Mathematical Institute, University of Oxford The staging system, wrote Braak in an e-mail to ARF, “has drawn attention to the damage in other transmitter systems—in other words, apart from and before the nigrostriatal system. In addition, it can serve as a framework for relating the pathology in other parts of the nervous system (gastrointestinal tract, spinal cord, and so on) to that in the brain.” The Braak model of PD staging hinges on the notion that Lewy pathology is not random: vulnerable sites in the brain are affected in a predictable topographic sequence (Figure 1). In support of this, Braak and colleagues have demonstrated that the cell types in the central nervous system (CNS) exhibiting a propensity for developing Lewy Skepticism concerning the dual-hit hypothesis and the Braak staging system derives in part from a number of discrepant findings in the neuropathology literature.

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. Dr. Dickson uses the Braak staging method, defined by German anatomist Heiko Braak in 2991.

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).

Braak staging suggests that the serotonergic and noradrenergic systems could become dysfunctional ahead of the dopaminergic system in PD. But PET studies with serotonergic markers show less midbrain pathology than the dopaminergic nigrostriatal system.
