Neuropathological alterations in Alzheimer disease.
The neuropathological hallmarks of Alzheimer disease (AD) include "positive" lesions such as amyloid plaques and cerebral amyloid angiopathy, neurofibrillary tangles, and glial responses, and "negative" lesions such as neuronal and synaptic loss. Despite their inherently cross-sectional nature, postmortem studies have enabled the staging of the progression of both amyloid and tangle pathologies...
متن کاملVariant Alzheimer disease with spastic paraparesis: neuropathological phenotype.
Variant Alzheimer disease (varAD) is clinically characterized by the combination of presenile dementia with spastic paraparesis and is caused by certain mutations of the presenilin 1 (PS-1) gene. We now present the unusual neuropathological phenotype of varAD as seen in 5 affected members of the original Finnish family with a genomic deletion encompassing exon 9 of the PS-1 gene. Their primary ...
متن کاملMicroglia in Alzheimer Brain: A Neuropathological Perspective
Microglia have long been noted to be present and activated in Alzheimer brain. Demonstrations that these microglia are associated with the specific lesions of Alzheimer disease-Aβ plaques and neurofibrillary tangles-and that these microglia overexpress the potent proinflammatory cytokine interleukin-1 led to the recognition of a potential pathogenic role for these cells in initiation and progre...
متن کاملContribution of Lewy body inclusions to dementia in patients with and without Alzheimer disease neuropathological conditions.
CONTEXT Lewy bodies (LBs) are intraneuronal inclusions in the brain that have been increasingly recognized as neuropathological lesions with relevance not only to Parkinson disease but also to Alzheimer disease. However, the degree to which the density of LBs in the brain contributes to the severity of dementia has not been clear. OBJECTIVE To determine the degree to which LB "burden" contrib...
متن کاملEffect of anti-inflammatory medications on neuropathological findings in Alzheimer disease.
BACKGROUND There has been no analysis of brain tissue from longitudinally observed, cognitively tested patients to validate whether anti-inflammatory medications protect against the pathological changes of Alzheimer disease. OBJECTIVE To investigate the role of anti-inflammatory medications in alleviating the pathological features of Alzheimer disease. DESIGN AND MAIN OUTCOME MEASURES A 5-y...
