Neuropathological observations in a case of autism presenting with self-injury behavior

Hof, P. R., Knabe, R., Bovier, P., Bouras, C.·1991·Acta Neuropathologica

Abstract

We report the neuropathological evaluation of a 24-year-old autistic woman suffering from a residual state of infantile autism and presenting with self-injury behavior since childhood. Her behavior included head-banging, eye-gouging and self-biting. All intended therapeutic measures remained without effect, including high doses of psychotropic drugs. At autopsy, numerous neurofibrillary tangles were found in the perirhinal and entorhinal cortex where they were frequently grouped in nests or clusters. A few neurofibrillary tangles were also observed in the amygdala and in the prepiriform and orbito-frontal cortex. In the cortex, tangles were located in both layers II and III. There were no neuritic plaques or amyloid deposits. Interestingly, neurofibrillary tangles have been described in brains of individuals who had experienced repeated head injuries such as boxers (dementia pugilistica) and soccer players, suggesting that in our case a similar mechanism induced tangle formation and resulted in the loss of selective neuronal populations.

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.
