Post-traumatic stress symptoms in childhood brain tumour survivors and their parents

Objectives This study aimed to investigate post-traumatic stress symptoms (PTSS) in childhood brain tumour survivors and their parents. A further aim was to explore the relationship between objective illness parameters, parent–child interactions, coping styles and PTSS. Methods A cross-sectional correlational design was employed. Fifty-two childhood brain tumour survivors, aged 8–16, and 52 parents completed a battery of questionnaires designed to assess quality of parent–child interactions, monitoring and blunting attentional coping styles and PTSS. Results Over one-third (35%) of survivors and 29% of their parents reported severe levels of PTSS (suggestive of post-traumatic stress disorder ‘caseness’). Increased parent–child conflict resolution for survivors and number of tumour recurrences for parents independently predicted the variance in PTSS. Conclusions For a substantial proportion of brain tumour survivors and their parents the process of survivorship is a considerably distressing experience.

Theory of mind in children with traumatic brain injury

Objective: This study was designed to examine the existence of deficits in mentalizing or theory of mind (ToM) in children with traumatic brain injury (TBI). Research design: ToM functioning was assessed in 12 children aged 6-12 years with TBI and documented frontal lobe damage and compared to 12 controls matched for age, sex and verbal ability. Brief measures of attention and memory were also included. Main outcome and results: The TBI group was significantly impaired relative to controls on the advanced ToM measure and a measure of basic emotion recognition. No difference was found in a basic measure of ToM. Conclusion: Traumatic brain damage in childhood may disrupt the developmental acquisition of emotion recognition and advanced ToM skills. The clinical and theoretical importance of these findings is discussed and the implications for the assessment and treatment of children who have experienced TBI are outlined.

The effects of bilingualism on the white matter structure of the brain

Recent studies suggest that learning and using a second language (L2) can affect brain structure, including the structure of white matter (WM) tracts. This observation comes from research looking at early and older bilingual individuals who have been using both their first and second languages on an everyday basis for many years. This study investigated whether young, highly immersed late bilinguals would also show structural effects in the WM that can be attributed to everyday L2 use, irrespective of critical periods or the length of L2 learning. Our Tract-Based Spatial Statistics analysis revealed higher fractional anisotropy values for bilinguals vs. monolinguals in several WM tracts that have been linked to language processing and in a pattern closely resembling the results reported for older and early bilinguals. We propose that learning and actively using an L2 after childhood can have rapid dynamic effects on WM structure, which in turn may assist in preserving WM integrity in older age.
