Prader-Willi Syndrome is a congenital disorder that is caused by a missing gene on part of chromosome 15. These children are found to have cognitive skills in the below average to mild mental retardation range.
Physical symptoms associated with Prader-Willi include:
- Newborns often present with low tone
- Almond shaped eyes
- Delayed motor development
- Short stature
- Very small hands and feet
The main symptom associated with Prader-Willi is a very strong interest in food with a lack of sensitivity to the physiological sensation of satiation. This means that the child will continue to eat with no sense of feeling full. Research has found that these children are at a very high risk to develop obesity and diabetes.
The main intervention that should be offered to these children is that the child works with a behaviorally trained therapist (psychologist or social worker) and a dietitian in order to develop healthier eating habits as well as behavioral incentives to decrease eating.
