Longitudinal Rett syndrome behaviour questionnaire scores and their associations with genotype and trajectories of mobility, weight and seizure frequency status

The Rett Syndrome Behaviour Questionnaire (RSBQ) describes behavioural and emotional features. This study investigated total RSBQ score trajectories and their clustering, and for trajectory groups, relationships with genotype and mobility, weight-for-age z scores, and seizure frequency.

Longitudinal trajectory of gross motor skills in school-aged children with Rett syndrome

In children with Rett syndrome, this study aimed to (1) describe gross motor skill trajectories; and (2) analyse the influences of genetic variant and comorbidities. This was a prospective longitudinal study conducted at the Danish National Center for Rett Syndrome 2008 to 2022.

Exploring Oral Health Related Quality of Life in Rett Syndrome Using Directed Content Analysis

No validated oral health-related quality of life (OHRQOL) instrument currently exists for those with severe intellectual and developmental disabilities and who communicate non-verbally. This qualitative study aimed to explore the domains that were important to the oral health-related quality of life in individuals with Rett syndrome.

Access to Oral Healthcare in Individuals With Rett Syndrome: A Qualitative Study of Parent Perspectives

Intellectual and developmental disabilities (IDD) are varied in their nature and presentation. Barriers to oral healthcare are reported in studies of general populations with IDD but these may not reflect the barriers experienced by individuals with rare disorders such as Rett syndrome.
