Challenging the concept of diffuse neurofibrillary tangles with calcification (Kosaka-Shibayama disease)

Challenging the concept of diffuse neurofibrillary tangles with calcification (Kosaka-Shibayama disease).

Diffuse neurofibrillary tangles with calcification: a new presenile dementia.

The term "diffuse neurofibrillary tangles with calcification" (DNTC) is proposed for a new form of presenile dementia. It is characterised by slowly progressive cortical dementia in the presenium, localised temporal or temporofrontal lobar atrophy, numerous neurofibrillary tangles widespread in the cerebral cortex, and pronounced calcareous deposits; 16 cases of DNTC, have been reported.

Neurofibrillary Tangles of Aβx-40 in Alzheimer's Disease Brains.

The two pathognomonic lesions in the brain of AD patients are senile plaques and intraneuronal neurofibrillary tangles (NFT). Previous studies have demonstrated that amyloid-β (Aβ) is a component of both senile plaques and NFTs, and have showed that intracellular accumulation of Aβ is toxic for cells and precedes the appearance of extracellular amyloid deposits. Here we report that there are nu...

Phosphorylated neurofilament antigens in neurofibrillary tangles in Alzheimer's disease.

Neurofibrillary tangles (NFT) are a hallmark of Alzheimer's disease (AD), and their presence correlates with the presence of dementia. A major constituent of NFT is the insoluble paired helical filament which shares some antigenic relationships with normal cytoskeletal elements, particularly neurofilaments. If neurofilament proteins (200, 145-160, and 68 kilodaltons [kd]) participate in the for...

Neurofibrillary tangles in nondemented elderly subjects and mild Alzheimer disease.

BACKGROUND The relationship between neuropathological lesions and mild, "preclinical," cognitive impairments of Alzheimer disease is poorly understood. Identification of the lesions that are most closely associated with the earliest symptoms of Alzheimer disease is crucial to the understanding of the disease process and the development of treatment strategies to affect its progression.
