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. However, one significant factor in how Lewy body dementia progresses is related to which disease is actually present. In Parkinson's disease dementia, the physical challenges are usually evident first, while in dementia with Lewy bodies, cognitive changes may appear earlier than, about the same time, or shortly after, the physical changes develop. Introduction. Lewy bodies (LB) are protein inclusions containing disaggregated oligomers of many cellular proteins. The German neurologist named Friederich Lewy was the first physician-scientist to describe the abnormal protein deposits in 1912 in people with paralysis agitans and, later on, Parkinson disease.

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. Lewy bodies are predominantly located in deeper cortical layers (layers 5 The staging in Parkinson's disease was described by Heiko Braak in 2003. Braak and colleagues state that Parkinson's disease begins when a foreign agent enters the body via the nose or gastrointestinal system and travels into the central nervous system (CNS).

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. 3.

Braak's PD staging suggests that LBD is a prion-like disease. Most typical PD cases fit with Braak's PD staging, but the scheme fails in … Staging/typing of Lewy body related alpha-synuclein pathology: being lowest in the limbic category (73%). When applying the staging protocol described by Braak and colleagues in 2003, agreement was only 65%, and in some cases as low as 36%. When modifications of these strategies, Lewy Bodies / … While the Braak tangle staging protocol can identify these stages, it uses an uncommon silver stain and hippocampal sample. The present study evaluates the Braak protocol using commonly used methods and cases fulfilling either CERAD criteria for Alzheimer's disease, criteria for dementia with Lewy bodies or without neurological disease. 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.

Key words: α-synuclein, Braak staging, dementia, Lewy body, Parkinson’s disease. INTRODUCTION In 1817, Parkinson described the clinical features of six cases of the disease named after him.1 In 1980, Kosaka et al. proposed the term Lewy body disease (LBD).2 In 1996, the ﬁrst consensus guideline on dementia with Lewy Currently, the neuropathological diagnosis of Lewy body disease (LBD) may be stated according to several staging systems, which include the Braak Lewy body stages (Braak), the consensus criteria by McKeith and colleagues (McKeith), the modified McKeith system by Leverenz and colleagues (Leverenz), and the Unified Staging System by Beach and colleagues (Beach). All of these systems use semi Neuropathological staging of Parkinson’s disease (Braak Staging).

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. 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. For both Lewy body-related disorders staging/classification systems based on semiquantitative assessment of the The broad importance of dementia is undisputed, with Alzheimer's disease justifiably getting the most attention. However, dementia with Lewy bodies and Parkinson's disease dementia, now called Lewy body dementias, are the second most common type of degenerative dementia in patients older than 65 years.
