Rett Syndrome Behaviour Questionnaire in Children and Adults With Rett Syndrome: Psychometric Characterization and Revised Factor Structure

Rett syndrome (RTT) is a severe neurodevelopmental disorder associated with multiple neurobehavioral abnormalities. The Rett Syndrome Behaviour Questionnaire (RSBQ) was developed for pediatric RTT observational studies. Because its application has expanded to adult and interventional studies, we evaluated the RSBQ's psychometric properties in six pediatric (n = 323) and five adult (n = 309) datasets.

Evaluation Tools Developed for Rett Syndrome

Rett syndrome (RTT) is a complex neurodevelopmental X-linked disorder associated with severe functional impairments and multiple comorbidities. There is wide variation in the clinical presentation, and because of its unique characteristics, several evaluation tools of clinical severity, behavior, and functional motor abilities have been proposed specifically for it.

CDKL5 deficiency disorder: clinical features, diagnosis, and management

CDKL5 deficiency disorder (CDD) was first identified as a cause of human disease in 2004. Although initially considered a variant of Rett syndrome, CDD is now recognised as an independent disorder and classified as a developmental epileptic encephalopathy.

New insight into Rett syndrome severity

A research collaboration between Australia and Israel has identified a genetic variation that influences the severity of symptoms in Rett syndrome.

Rett syndrome research reveals high fracture risk

Girls and young women with Rett syndrome are nearly four times more likely to suffer a fracture.

New study reveals Rett syndrome can strike males

A new study has found that the genetic flaw responsible for Rett syndrome can strike males, even where there isn't a family history of the rare brain disorder.

Down Syndrome

Down syndrome, also known as Trisomy 21, is one of the most common chromosome abnormalities in humans. It occurs when a child's cells end up with 47 chromosomes instead of the usual 46. Down syndrome causes intellectual disability and other physical and learning challenges.
