About Prader-Willi Syndrome
Prader-Willi syndrome (PWS) is a rare genetic condition caused by the loss of function of specific genes on chromosome 15. It affects approximately 1 in 15,000 to 25,000 births.
PWS is a complex condition that affects many parts of the body and brain. The most well-known feature is hyperphagia (an overwhelming, constant drive to eat), which typically develops in early childhood. This is caused by the hypothalamus in the brain not functioning correctly, meaning the person never feels full. Without careful management, this can lead to life-threatening obesity.
However, PWS involves much more than food-related behaviour. Children with PWS often have a distinctive learning profile with particular strengths alongside challenges. The PWSA UK emphasises the importance of understanding the whole child, not just the eating behaviour.
Strengths and Learning Profile
Common Strengths
- Long-term memory is often a relative strength
- Visual learning and processing skills
- Reading ability may be a strength, particularly word recognition
- Good receptive vocabulary
- Enjoyment of routine and structured activities
- Creative abilities in art, drama and music
- Kind, friendly and sociable nature
- Jigsaw puzzles and word searches are often enjoyed
Common Challenges
- Hyperphagia (constant, overwhelming hunger; this is neurological, not a lack of willpower)
- Moderate learning difficulties (most children have an IQ in the range of 60-70, though this varies)
- Short-term auditory memory difficulties
- Mathematics and abstract thinking are typically challenging
- Difficulty with social understanding and managing emotions
- Behavioural challenges including rigidity, temper outbursts, repetitive questioning and difficulty with change
- Low muscle tone (hypotonia), which affects motor skills, stamina and posture
- Skin picking (a compulsive behaviour associated with PWS)
- Speech articulation difficulties
- Temperature regulation difficulties
- Excessive daytime sleepiness
Classroom and School Strategies
Food and Environment Management
- Develop a clear, consistent food plan in the IHP, agreed with parents and the dietitian
- Remove all unsupervised access to food (lock cupboards, keep food out of sight)
- Never use food as a reward or punishment
- Supervise mealtimes and ensure the agreed portion sizes are followed
- Brief all staff (including supply teachers, catering staff and trip leaders) about the food management plan
- Provide clear, consistent routines around mealtimes and snacks
- Be aware that the pupil may attempt to access food from other children's lunch boxes, bins or kitchens
- Plan carefully for food-related events (parties, food technology lessons, fundraisers)
Supporting Learning
- Use visual supports, concrete resources and structured teaching approaches
- Present information visually wherever possible, as visual memory is a strength
- Keep verbal instructions short and simple; support with visual prompts
- Provide plenty of repetition and overlearning
- Break tasks into small, achievable steps with clear success criteria
- Use the pupil's interests and strengths as motivators
- Provide structured, predictable routines; prepare the pupil for any changes well in advance
- Allow extra time for task completion
Managing Behaviour and Emotional Regulation
- Provide a highly predictable environment with clear expectations and consistent boundaries
- Prepare the pupil for transitions and changes in routine well in advance
- Avoid direct confrontation during temper outbursts; give the pupil time and space to calm down
- Use a calm, matter-of-fact approach to repetitive questioning
- Provide opportunities for choices within a structured framework
- Teach social skills explicitly and provide regular opportunities for practice
- Be aware that anxiety often underlies challenging behaviour
- Use positive reinforcement (non-food rewards) and celebrate achievements
Physical Activity
- Encourage regular physical activity, which is important for weight management and wellbeing
- Be aware of low muscle tone and reduced stamina; adapt activities accordingly
- Monitor for overheating, as temperature regulation can be affected
- Provide rest breaks as needed
