Abstract

We report on the neuropathological examinations of a 74‐year‐old woman with Alzheimer's disease (AD) and of her 47‐year‐old nondementd daughter. The brain of the mother showed fully developed pathological changes of AD. By contrast, the brain of the daughter revealed only perineuronal deposition of diffuse amyloid in cerebral cortex and striking abnormalities of the endosomallysosomal system, without neurofibrillary, glial, or microglial changes. These observations suggest that amyloid deposition and endosomal‐lysosomal changes are early events in late‐onset AD and that they may precede the onset of dementia of several decades.

  • The validity of the concept of a preclinical stage in Alzheimer's disease is supported by longitudinal clinical studies of mild memory changes followed by an accelerated decline and by clinical-pathological studies that report the presence of the characteristic lesions of Alzheimer's disease in cognitively normal individuals.

    “The validity of the concept of a preclinical stage in AD is supported by longitudinal clinical studies of mild memory changes followed by an accelerated decline [6,15,19,33] and by clinical-pathological studies that report the presence of the characteristic lesions of AD in cognitively normal individuals [1,23,35,36].”

  • Some studies suggest that Aβ deposits in the brain may precede the onset of cognitive decline by a decade or more, indicating a wide temporal window for neuronal protective therapeutic intervention.

    “Some of these studies suggest that the A␤ deposits in the brain may precede the onset of cognitive decline by a decade or more [27,36], indicating the presence of a wide temporal window for neuronal protective therapeutic intervention.”

  • Senile plaques and neurofibrillary tangles in nondemented older adults may represent Alzheimer disease before clinical expression, with lesions accumulating over many years before synaptic and neuronal damage produces symptoms.

    “Alternatively, the presence of SPs and NFTs in nondemented older adults may represent AD at a stage prior to its clinical expression,(Morris et al., 1996; Price & Morris, 1999; Troncoso et al., 1998; Hulette et al., 1998; Schmitt et al., 2000) in which the neuropathological lesions of AD accumulate over many years before sufficient synaptic and neuronal damage occurs to produce the symptoms of AD.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
