Abstract

In this study the cellular morphology in the human fascia dentata of 5 very old demented cases (4 Alzheimer's disease and 1 multi-infarct dementia patients) was compared with 5 (very) old controls cases. The postmortem delay in fixation was for all cases within 3.5 h. In the demented group, a significant reduction in thickness of the molecular layer, density of dendritic spines in the middle third of the molecular layer and total dendritic length (+/- 30%) was found. The number of dendritic segments, indicative of the branching frequency showed no difference. In both the control and the demented group, three-quarters of all dendritic bifurcations of granule cells occurred in the inner third of the molecular layer in which the commissural and associational fibers terminate. The size of the dendrites in the demented group could be the result of at least 3 independent processes: a regressive change due to partial denervation of the outer two-thirds of the molecular layer as axons from the perforant pathway are lost; a dendritic regrowth in response to sprouting of the commissural-associational fiber systems and septal afferents, which is presumed to occur in response to degeneration of perforant path axons; a dendritic regrowth in response to the loss of the dendrites of neighboring cells which have died. Analysis of our material suggests that dendritic degeneration is the predominant factor in the demented group.

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.
