When modifications of these strategies, i.e., McKeith's protocol by Leverenz and colleagues from 2009, Braak's staging by Müller and colleagues from 2005 were applied then the agreement increased to 78 and 82% The pattern that he identified has been termed the Braak Staging of Lewy Body inclusions. More current research shows that Lewy Body pathology can spread from one area of the nervous system to another, and it's conceivable that this happens in a prion-like fashion .

Lewy body sjukdom

We used an autopsy series to determine whether the newest dementia with Lewy bodies (DLB) consensus pathologic classification correlates with premortem diagnosis of DLB. According to the Braak staging, a classification of the disease based on pathological findings proposed by Heiko Braak, Lewy bodies first appear in the olfactory bulb, medulla oblongata and pontine tegmentum; individuals at this stage may be asymptomatic or may have early non-motor symptoms (such as loss of sense of smell, or some sleep or automatic dysfunction).

A total of fourteen brains from former athletes with a history 2004-05-14 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). The presence of Lewy bodies in the enteric and peripheral nervous systems supports Incidental Lewy body disease and PD can show Lewy pathology in substantia nigra or other brain areas without involvement of dorsal motor nucleus of the vagus nerve. The Braak staging system is valid for PD patients with young onset, long duration with motor symptoms, but not for others, e.g., late onset and rapid course PD. 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. Most typical PD cases fit with Braak's PD staging, but the scheme fails in some cases. While the Braak tangle staging protocol can identify these stages, it uses an uncommon silver stain and hippocampal sample.
