Assessment of hyperphagia in Prader-Willi syndrome.
OBJECTIVE Prader-Willi syndrome (PWS), the leading known genetic cause of obesity, is characterized by intellectual disabilities, maladaptive and compulsive behaviors, and hyperphagia. Although complications of obesity resulting from hyperphagia are the leading cause of death in PWS, quantifying this drive for food has long been an unmet research need. This study provides factor-analytic and wi...
متن کاملPrader-Willi syndrome and hyperphagia: a challenge to investigate.
Prader-Willi syndrome (PWS) is a genetic disease caused by the loss of expression of genes of paternal origin in the region 15q11--q13 of chromosome 15. The main characteristics of the syndrome include neonatal hypotonia, feeding problems in infancy, characteristic facies, intellectual disability, behavioral changes, GH deficiency, hypogonadism, and hyperphagia. Hyperphagia leads to the develop...
متن کاملPrader-Willi Syndrome
Prader-Willi syndrome is a neurogenetic disorder characterized by hypotonia and feeding difficulties in infancy, followed by hyperphagia, hypogonadism, mental retardation, and short stature. It was the first recognized microdeletion syndrome identified with high-resolution chromosome analysis, the first recognized human genomic imprinting disorder, and the first recognized disorder resulting fr...
متن کاملPrader-Willi syndrome.
Prader-Willi syndrome is a multi system disorder characterized by neonatal hypotonia, later obesity, hyperphagia and mental retardation. It occurs sporadically, either as a result of microdeletion of chromosome 15p (70%) or as a result of maternal disomy of chromosome 15 (30%). The major problems encountered by parents are those of hyperphagia, food-seeking and obesity, and conduct disorder, pa...
متن کاملPrader-willi Syndrome
Prader–Willi syndrome (PWS) is a genetic disorder due to loss of function of specific genes on chromosome 15. It occurs in males and females, no matter what race. As an infant, PWS shows itself in weak muscle tone (hypotonia, Pic. 1), feeding difficulties, poor growth, and delayed development. In the beginning during childhood, characterizes itself by having the kids develop an insatiable appet...
