“When Rituals or Obsessions Become a Problem” in People with Prader-Willi Syndrome

Many people with Prader-Willi Syndrome (PWS) engage in repetitive behaviours and rituals. Sometimes these behaviours can be beneficial and are often used by parents and carers to implement a predictable routine. 

However, not all rituals are beneficial and over time some people with PWS can become so set in following a routine that this can lead to problems, for example hoarding or refusing to do anything until they have completed a particular routine.
