Nutritional phases in Prader-Willi syndrome

Nutritional phases in Prader-Willi syndrome.

Prader-Willi syndrome (PWS) is a complex neurobehavioral condition which has been classically described as having two nutritional stages: poor feeding, frequently with failure to thrive (FTT) in infancy (Stage 1), followed by hyperphagia leading to obesity in later childhood (Stage 2). We have longitudinally followed the feeding behaviors of individuals with PWS and found a much more gradual an...

Prader-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...

Prader-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...

Prader-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...
