How it is diagnosed?

Clinicians will firstly observe indicative characteristics of the baby or child. A genetic test, through a blood sample is then done, to seek confirmation.

How is it characterised?

Often PWS significantly impacts behaviour, learning, mental and physical health. People living with PWS can exhibit high anxiety, complex and at times challenging behaviour, cognitive dysfunction, poor judgement and are often socially isolated throughout their lives. A defining feature of PWS is hyperphagia, a compulsive urge to over-eat. The characteristics change with age. Visit the international PWS organisation to learn more.

Is there a cure?

There is no cure for PWS, but people with the disorder can benefit from a variety of treatments to improve their symptoms. These treatments depend on the individual’s needs, but they often include strict dietary support or supervision, physical therapy, behavioral therapy, and treatment with growth hormone, among others.
