Comparing Parental Well-Being and Its Determinants Across Three Different Genetic Disorders Causing Intellectual Disability.

Using the Short Form 12 Health Survey this cross-sectional study examined parental well-being in caregivers of children with one of three genetic disorders associated with intellectual disability; Down syndrome, Rett syndrome and the CDKL5 disorder. Data were sourced from the Western Australian Down Syndrome (n = 291), Australian Rett Syndrome (n = 187) and International CDKL5 Disorder (n = 168) Databases. Among 596 mothers (median age, years 43.7; 24.6-72.2), emotional well-being was poorer than general female populations across age groups. Multivariate linear regression identified the poorest well-being in parents of children with the CDKL5 disorder, a rare but severe and complex encephalopathy, and negative associations with increased clinical severity irrespective of diagnosis. These findings are important for those providing healthcare and social services for these populations.
