2013-05-08 · 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 pathology share common features.

NFT pathology graded according to Braak staging was selected as the main dependent variable of interest. Briefly, neuropathological assessment was performed on one hemisphere (left side for most cases), which was fixed in paraformaldehyde and embedded in paraffin. Tissue blocks were then dissected from 0.5‐1 cm slabs.

Heiko Braak (* 16. Juni 1937 in Kiel ) 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.

Braak and Braak, 1991 proposed a neuropathological staging to differentiate initial, intermediate, and advanced AD based on the spread of neurofibrillary tangles (NFTs) within the medial temporal lobe (MTL) memory circuit: Braak stage 0 corresponds to absence of NFTs, stages I–II to entorhinal-perirhinal cortex NFTs, stages III–IV to NFTs additionally in hippocampus and stages V–VI to NFTs distributed in wider neocortical areas. Braak staging of the pathology of PD Braak and colleagues have outlined their concept of staging PD with great clarity in many publications 4, 5, 10, 11, so it will suffice here to summarize their principal findings. Their observations are depicted schematically in Figure 1 (based on Braak, 2006 11). 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 associated 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. 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).

The Braak staging is a matter of vigorous debate, since < 100% of A staging system describing the spread of LP from the peripheral to the central nervous system was also postulated by the same research group.

The stages were compared with clinicopathological factors, including seizure history and presence of old traumatic brain injury.

Development of the pretangle material into argyrophilic neurofibrillary lesions characterizes Stages I to VI as follows: deep blue for Stage I and II cases, dark blue for Stage III and IV cases, and black for Stage V and VI cases. Schöll adapted this staging scheme for in vivo tau PET by defining three large regions of interest that matched Braak stages I/II, III/IV, and V/VI.
