During my time ApoE-ε4 is associated with an increased amount of tau pathology in the olfactory bulbs immunoreactivity in AD patients (Ohm & Braak, 1987; Talamo et al.,. 1989). rofibrillära nystan (tau-protein).

2016-03-02 Braak staging refers to two methods used to classify the degree of pathology in Parkinson's disease and Alzheimer's disease. 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. Braak stages 4–6 represent the more typically recognized stages of pathology, in which the appearance of tau tangles and tau-positive neuritic plaques appear at approximately the same time. Individualized Tau PET Model Outperforms Predictive Power of Braak Staging.

KW Autopsy studies suggest, however, that tau deposition follows Braak staging, beginning more focally in the medial temporal lobes, spreading through inferolateral temporal lobes, and finally to diffuse cortical regions (Braak and Braak, 1997).

Braak graded the presence, distribution, and density of tau tangles in the brain and defined six distinct stages of Alzheimer’s progression (Braak stages). Tau seeding levels were detected not only in the brain regions impacted by pathology, but also in the subsequent non-pathology containing region along the Braak pathway. These data imply that pathogenic tau aggregates precede overt tau pathology in a manner that is consistent with transneuronal spread of tau aggregates. Microtubules also destabilize when tau is dissociated. The combination of the neurofibrillary tangles and destabilized microtubules result in disruption of processes such as axonal transport and neural communication. The degree of NFT involvement in AD is defined by Braak stages.

Braak stages I and II are used when NFT involvement is confined mainly to the trans entorhinal region of the brain. Stages III and IV are indicated when there is involvement of limbic regions such as the hippocampus, and V and VI when there's extensive neocortical involvement.
