10 Exceptional subtypes are classified by the DLB consensus criteria as olfactory‐bulb only and amygdala‐predominant LBD. 10 Braak's PD staging was originally proposed for PD, not for all LBD including For the Lewy body variant, preclinical PD cannot be excluded, although according to the Braak staging system, the occurrence of Lewy bodies in the locus caeruleus should be preceded by involvement of the dorsal vagal nucleus. 71.

The staging focuses on the location of NFTs.
For each region, Lewy bodies are counted from the depth of the sulcus to the lip. Counts are not made over the crest of the gyri except for the cingulate gyrus.

For both LB-related disorders, staging/classification The Braak hypothesis considers the appearance of Lewy bodies as harmful. Although these alpha synuclein deposits are associated with several neurodegenerative diseases such as Parkinson’s disease and head damage, it is not entirely clear that the Lewy bodies cause the damage. In some cases, they may be protective.

Although these alpha synuclein deposits are associated with several neurodegenerative diseases such as Parkinson’s disease and head damage, it is not entirely clear that the Lewy bodies cause the damage. In some cases, they may be protective. 2007-10-02 Braak based his staging system on the detection of Lewy bodies. However, whereas smaller aggregates of α-synuclein have been shown to cause neuronal cells to die, a growing number of scientists now believe the formation of the larger Lewy bodies may actually serve to protect neurons from damage. predominant type of Lewy body disease, and dementia with Lewy bodies (DLB), are neurodegenerative multisystem disorders with widespread occurrence of a-synuclein containing deposits in the central and peripheral autonomic systems.
Counts are not made over the crest of the gyri except for the cingulate gyrus. Lewy bodies are predominantly located in deeper cortical layers (layers 5 and 6). In each region a count of up to 5 Lewy bodies in the cortical ribbon gives a score of 1 in the table. In 2003, Heiko Braak identified a pattern of Lewy body deposition, in the synucleinopathies (the term that is given to any disease that results in the accumulation of alpha-synuclein proteins), which include Parkinson's Disease (PD), Multiple Systems Atrophy (MSA), Progressive Supra-nuclear Palsy (PSP) and Dementia (LBD). The Braak staging scheme for PD has already begun to receive wide acceptance 8, 9. Given the significant influence of the Braak staging scheme and its likely impact on future PD research directions, it seems critical to assess whether its scientific validity has been affirmed, and to consider issues that will require further investigation. Clinical diagnosis of DLB, however, depended on the presence of low Alzheimer disease pathology (by Braak staging) rather than on Lewy body distribution.

reported that the intracerebral formation of Lewy inclusion bodies and Lewy neurites has a topographically predictable progression. Braak staging. Interestingly, a study which examined the location of Lewy bodies in post-mortem brains of patients with early stages of PD to brains of patients with advanced stages of the disease, found that the Lewy bodies progress in a predictable manner from one brain region to another. This is called Braak staging. Lewy bodies found in 88/145 (60.7%) of CERAD cases and 56.8% of 95 cases with Braak stage 5-6) First large study using α-synuclein immunohistochemistry in late onset sporadic AD cases The amygdala was severely involved in all cases Cortical Lewy body score: 0–2 Brainstem-predominant, 3–6 Limbic or ‘transitional’, 7–10 Neocortical. For each region, Lewy bodies are counted from the depth of the sulcus to the lip. Counts are not made over the crest of the gyri except for the cingulate gyrus.

Braak et al.'s 2003 paper detailing the caudo-rostral progression of Lewy body pathology (LP) formed the foundation of current understanding of disease spread in Parkinson's disease (PD); however, its methods are difficult to recreate and consequently multiple new staging systems emerged to recapitulate Braak's staging system using standard neuropathological methods and to account for other
However, some patients with dementia with Lewy bodies do not follow the caudorostral progression, suggesting that alternative patterns of spread are possible.22 The proposed Braak staging excluded patients with dementia with Lewy bodies, and so the applicability of caudorostral progression to the disease is not established.

Lewy bodies are the inclusion bodies – abnormal aggregations of protein – that develop inside nerve cells affected by Parkinson's disease (PD), the Lewy body dementias (Parkinson's disease dementia and dementia with Lewy bodies), and some other disorders.They are also seen in cases of multiple system atrophy, particularly the parkinsonian variant (MSA-P).

2019 Oct 1;78(10):891-899. doi: 10.1093/jnen/nlz080. Braak hypothesized that Lewy pathology progresses ascendingly from the peripheral nervous system to the olfactory bulbs and brainstem and then to other brain regions. Braak's PD staging suggests that LBD is a prion-like disease.
The Lewy body accumulation in these regions could lead to the REM sleep behavior disorder. The Braak hypothesis offers the hope that if the pathology were detected in its early stages, then the spread of the Lewy bodies into the higher areas of the brain can be prevented.
