Too much insulin — a hormone that controls sugar in blood — may set off weight gain and excessive eating (known as hyperphagia) in children with Prader-Willi syndrome (PWS), a study suggests. High levels of insulin occurred hand in hand with high levels of leptin, a hormone that controls…
EMO-T, a new emotional skill training program, helped children with Prader-Willi syndrome (PWS) express, recognize, understand, and regulate emotions, a study suggested. After EMO-T, scores related to emotional expression and comprehension matched those of control participants without PWS. Regulating and expressing emotions requires prerequisite emotion skills, said the researchers,…
Early treatment with Jintropin, a form of human growth hormone, was associated with improvements in cognition and appeared to slow the decline in motor function among children with Prader-Willi syndrome (PWS), a new study reports. “The present findings of this study add to the growing evidence that [human growth…
