Abstract

Dysfunction of various hypothalamic systems may be the basis of a number of symptoms in Prader—Willi syndrome. The often abnormal position of the baby in the uterus at the onset of labour, the high percentage of infants with asphyxia and the high proportion of children born prematurely or post‐maturely may all be related to abnormal fetal hypothalamic systems, as the fetal hypothalamus plays a crucial role in labour. Abnormal luteinizing hormone‐releasing hormone neurones are thought to be responsible for the decreased levels of sex hormones, resulting in non‐descended testes, undersized sex organs and insufficient growth during puberty. A lack of growth hormone‐releasing hormone may also contribute to the short stature of patients with Prader—Willi syndrome. In addition, the aberrant control of body temperature and daytime hypersomnolence may result from hypothalamic disturbances. The number of oxytocin neurones – the putative satiety neurones – in the hypothalamic paraventricular nucleus is markedly decreased in Prader—Willi syndrome. This is presumed to be the basis of the insatiable hunger and obesity of patients with the syndrome. □ Growth hormone, growth hormone‐releasing hormone, hypothalamus, insatiable hunger, obesity, oxytocin, perinatal problems, Prader—Willi syndrome

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.
