Study: PWS Doesn’t Increase Risk of Severe COVID-19

Children and adults with Prader-Willi syndrome (PWS) are not at higher risk of developing a severe COVID-19 infection, according to results from a survey involving more than 500 patients in France. These findings were particularly surprising in terms of the adult population, which typically has several known risk factors for severe…

Patient-derived ‘Mini-brains’ May Help in Understanding PWS

New brain-like organoids, or “mini-brains,” that are specific to key regions and derived from patients could serve as models for studies of the underlying neurological and molecular mechanisms of Prader-Willi syndrome (PWS), researchers reported. Notably, the team created arcuate organoids generated from cells of PWS patients, which captured the arcuate…

Advocacy Groups Oppose Additional Trial for DCCR

The Foundation for Prader-Willi Research (FPWR) and the Prader-Willi Syndrome Association (PWSA) in the U.S. have asked the U.S. Food and Drug Administration (FDA) to reconsider its request for an additional clinical trial of diazoxide choline controlled release (DCCR) tablets in patients with Prader-Willi syndrome (PWS). Last month, the…

Mental Rigidity in PWS Goes Beyond Intellectual Disability

Adults with Prader-Willi syndrome (PWS) have greater mental rigidity than those with matching intellectual disability, but without the disease, and those with normal intellectual level, according to a study from France. These findings support the presence of PWS-specific mental flexibility deficits, over and above intellectual problems, the researchers said.
