Attention Deficit Hyperactivity Disorder (ADD/ADHD) |
Prader-Willi Syndrome What is Prader-Willi syndrome? Prader-Willi Syndrome is the most common genetic cause of life-threatening obesity in children. People with Prader-Willi syndrome have a problem in their hypothalamus, a part of the brain that normally controls feelings of fullness or hunger. As a result, they never feel full and have a constant urge to eat that they cannot control. Most cases of Prader-Willi syndrome result from a spontaneous genetic error in genes on chromosome 15 that occurs at conception. In very rare cases, the mutation is inherited. What are the symptoms of Prader-Willi syndrome? There are generally two stages of symptoms for people with Prader-Willi syndrome: Stage 1--As newborns, babies with Prader-Willi can have low muscle tone, which can affect their ability to suck properly. As a result, babies may need special feeding techniques to help them eat, and infants may have problems gaining weight. As these babies grow older, their strength and muscle tone usually get better. They meet motor milestones, but are usually slower in doing so. Stage 2--Between the ages of 1 and 6 years old, the disorder changes to one of constant hunger and food seeking. Most people with Prader-Willi syndrome have an insatiable appetite, meaning they never feel full. In fact, their brains are telling them they are starving. They may have trouble regulating their own eating and may need external restrictions on food, including locked kitchen and food storage areas. This problem is made worse because people with Prader-Willi syndrome use fewer calories than those without the syndrome because they have less muscle mass. The combination of eating massive amounts of food and not burning enough calories can lead to life-threatening obesity if the diet is not kept under strict control. There are other symptoms that may affect people with Prader-Willi, including:
Prader-Willi syndrome is considered a spectrum disorder, meaning not all symptoms will occur in everyone affected and the symptoms may range from mild to severe. People with Prader-Willi often have some mental strengths as well, such as skills in jigsaw puzzles. If obesity is prevented, people with the syndrome can live a normal lifespan. What are the treatments for Prader-Willi syndrome? Prader-Willi syndrome cannot be cured. But, early intervention can help people build skills for adapting to the disorder. Early diagnosis can also help parents learn about the condition and prepare for future challenges. A health care provider can do a blood test to check for Prader-Willi syndrome. Exercise and physical activity can help control weight and help with motor skills. Speech therapy may be needed to help with oral skills. Human growth hormone has been found to be helpful in treating Prader-Willi syndrome. It can help to increase height, decrease body fat, and increase muscle mass. However, no medications have yet been found to control appetite in those with Prader-Willi.
