Subtle heart changes in people with Prader–Willi syndrome (PWS) may begin relatively early in adulthood, and being overweight may be related to these cardiovascular abnormalities, a small study reported. “We need to manage obesity and obesity-related disorders in order to prevent heart failure and ischemic heart disease [reduced blood…
Infants and toddlers with Prader-Willi syndrome (PWS) have significantly lower blood levels of insulin-like growth factor 1 or IGF-1 — indicative of growth hormone (GH) deficiency — than their healthy peers, a small study in Japan shows.

A multidisciplinary approach that included weight reduction through calorie restriction and diuretics, ventilation support, skin care, and rehabilitation successfully managed life-threatening right heart failure due to severe obesity in a young man with Prader-Willi syndrome (PWS). These findings from a case study highlight not only the effectiveness of such a…
During pregnancy, Prader-Willi syndrome (PWS) may manifest as an excess of fluid around the developing fetus coupled with restricted fetal growth and decreased fetal movement, a new report indicates. These signs should alert clinicians to consider testing for the possibility of a PWS diagnosis, the researchers wrote. The…
Suicidal thoughts are more frequent in adults with Prader-Willi syndrome (PWS) than in the general population and typically begin in mid-teenage years, according to a study using the Global PWS Registry. In contrast, youths with PWS appear to have fewer suicidal thoughts than the general population of children and…
There is no substantial evidence supporting the efficacy of LV-101 (intranasal carbetocin), a nasal spray designed to reduce the insatiable hunger, called hyperphagia, that’s a hallmark of Prader-Willi syndrome (PWS), according to a 12-1 vote by a U.S. Food and Drug Administration (FDA) advisory committee.
