What is Prader-Willi syndrome?

Prader-Willi syndrome is a very rare genetic condition affecting 1 in 22,000¹ people worldwide and there are approximately 2000¹ adults living with the condition in the UK.

The condition caused by a defect of chromosome 15. This defect affects the part of the brain in charge of managing hormones, controlling appetite and regulating emotions. 

This has a significant impact on the mental, physical and behavioural well-being of people with Prader-Willi syndrome. It can lead to the development of a variety of complex needs including learning disabilities, physical symptoms and behavioural problems.

Normally diagnosed shortly after birth, it is most commonly associated with:

• Excessive appetite and overeating
• Weight gain
• A lack of muscle tone
• Delayed growth

Although there is no cure for Prader-Willi syndrome, with the right care and support in place people with the condition can lead long, healthy, fulfilling lives.
