Screening for neurofibrillary tangles and argyrophilic plaques with Congo Red and polarized light.
The capricious nature of silver impregnation techniques renders them unsuitable for bulk staining and screening sections for the presence of argyrophilic (senile) plaques and neurofibrillary tangles. For this purpose, we describe a simple, consistent and highly sensitive bulk staining method. It depends on the congophilia and resultant anomalous colour or polarization (Ladewig, 1945) that chara...
متن کاملSenile plaques and neurofibrillary tangles in cortical neurons in AD
Neurodegenerative disorders are characterized clinically by insidious onset and slowly progressive course, and are frequently hereditary. Pathologically, these diseases share a common feature: the selective loss of a particular subset of neurons for unknown reasons [e.g. cerebral cortical neurons in ALZHEIMER’S DISEASE (AD) (see Glossary), substantia nigra neurons in PARKINSON’S DISEASE (PD), s...
متن کاملThe molecular biology of senile plaques and neurofibrillary tangles in Alzheimer's disease.
Since the earliest descriptions of the disease, senile plaques (SP) and neurofibrillary tangles (NFT) have been regarded as the pathological 'hallmarks' of Alzheimer's disease (AD). Whether or not SP and NFT are sufficient cause to explain the neurodegeneration of AD is controversial. The major molecular constituents of these lesions, viz., beta-amyloid (Ass) and tau, have played a defining rol...
متن کاملIs there a spatial association between senile plaques and neurofibrillary tangles in Alzheimer's disease?
OBJECTIVE To test the hypothesis that the clusters of senile plaques (SP) and neurofibrillary tangles (NFT) in patients with Alzheimer's disease (AD) are spatially associated as predicted by the 'Amyloid Cascade Hypothesis'. METHODS The spatial association between the SP and NFT was studied in the cerebral cortex and hippocampus in six cases of sporadic Alzheimer's disease (AD) using continge...
متن کاملNeuropathology for the neuroradiologist: plaques and tangles.
Histologically identified intracellular and extracellular inclusions and structures often provide a tissue diagnosis of a specific disease process. Moreover, these deposits may provide clues about the pathogenesis of the disease in which they are found. Two distinctive structures seen within the brains of patients clinically diagnosed with dementia of the Alzheimer type are extracellular plaque...
