Clinical severity and quality of life in children and adolescents with Rett syndrome.

Summary: Rett syndrome is a genetic disorder affecting development in girls. In a large study following over 200 girls aged 5 to 18, researchers looked at how the severity of the disease affects their quality of life. While severe physical symptoms predictably led to a lower physical quality of life, the results for social and emotional well-being were surprising. Girls with worse motor skills actually scored better on psychosocial measures, while those with better movement abilities reported lower psychosocial quality of life. This suggests that as girls with Rett syndrome gain more awareness or ability to interact with the world, they may experience more social or emotional challenges. These findings highlight the importance of using specific tools, like the Child Health Questionnaire, to accurately measure the success of future treatments.
