Alzheimer Degeneration in Down Syndrome: Electrophysiologic Alterations and Histopathologic Findings

Crapper, Donald R.·1975·Archives of Neurology

Abstract

Progressive electroencephalographic disorganization and decreased voltage amplitude in the late components of the averaged visual evoked potentials were recorded in the last two years of life of a patient with Down disease and Alzheimer degeneration. Taken together with quantitative histopathologic findings, the electrophysiologic alterations are interpreted in terms of recent evidence from an experimental animal model of dementia. Neurons with neurofibrillary degeneration become electrically inactive and contribute to the loss of voltage generators associated with neuron death in Alzheimer disease. Loss of voltage generators may result in disfacillitation and disinhibition of surviving neurons, thus causing the loss of normal rhythms.

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.
