Abstract

The neuropathology of the Rett syndrome is summarized utilizing a format of clinical pathological correlations, describing the pathology at specific anatomic sites which could correlate with the well defined clinical signs and symptoms in the Rett syndrome; decreased head and body size, autism, gait dysfunction, spasticity, movement and breathing disorder. Published reports of altered morphology in the cerebral cortex, basal ganglia, substantia nigra, cerebellum, spinal cord, muscle, nerve, pituitary gland and somatic organs are supplemented by the author's observations. These include studies of dendritic morphology employing Scholl analysis of Golgi preparation, and quantitation of cerebellar Purkinje cells. The possible pathoetiology of the Rett syndrome is considered, particularly, in relation to the ultrastructural demonstration of altered mitochondria and accumulations of lipidic bodies in several tissues.

“The results of the present study conﬁrm that the T158M mutation reduces MeCP2 levels in the brain, affecting the brain’s weight and size, and the protein expression in the brain—ﬁndings that may relate to the pathology of RTT in human patients [60,61].”

“This perfectly matches the conditions in RTT, which is not characterized by a loss of neuronal elements, but rather a state of immaturity and miscommuni-cation of the affected neuronal networks (Armstrong, 2005; Boggio et al., 2010; Moretti et al., 2006).”

“…in layers 2, 3, and 5 of the motor cortex, which and prefrontal cortex exhibit the most marked decrease in dendritic complexity and spine density (Leontovich et al., 1999), however, less dramatic alterations are seen in the hippocampal and visual cortex (Belichenko et al., 1997; Armstrong, 2005).”

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.
