Quality of life and neurological disability in children and young people with ataxia telangiectasia.

To explore neurological factors affecting quality of life (QoL) in children and young people with ataxia-telangiectasia (A-T), from both child and parent perspective. 24 children/young people with A-T (mean age 11.2 ± 3.5 years; 13 males) and 20 parents were recruited, and 58% were reassessed after an average interval of 3.4 years. Participants completed the PedsQL QoL assessment. Participants with A-T underwent structured neurological examination. QoL data from 20 healthy controls and their parents was used for comparison. Children/young people with A-T rated their QoL higher than parental ratings across time points, with no longitudinal change. Higher age of the child participant correlated with lower parental (r = −0.43, p =.008) but not child ratings of QoL (r = −0.16, p =.380). Child and parent QoL ratings from the A-T group were lower than respective ratings from controls (η p ² = 0.44 and η p ² = 0.75 respectively, both p <.0005, controlled for socioeconomic status). Parental, but not child, ratings of QoL was predicted by a regression model based on neurological scores (R ² = 0.44, p =<.001). Neurological disability does not determine child/young person QoL ratings in A-T. While certain aspects of neurological disability predict parent-proxy ratings, there is no decline in QoL over time. These results may reflect resilience in the face of a complex life-limiting disorder. [Display omitted] • Child ratings of QoL in A-T are significantly higher than parental ratings. • Age negatively correlated with parent QoL ratings, but there was no relationship between age and child QoL self-ratings. • Neurological function significantly predicts parental, but not the child's own ratings of their QoL. • Over time, QoL ratings did not decline with increasing disability reflecting high levels of resilience in this sample.
