To investigate cognitive functioning and emotional distress in adults aged 55 to 68 years old with spina bifida myelomeningocele (SBM), both with and without hydrocephalus. A secondary aim was to explore the associations between psychosocial factors in relation to emotional distress. Cross-sectional study of eleven females and eight males with SBM, five with and twelve without hydrocephalus. Cognitive functioning was investigated with neuropsychological tests and self-report measures. Furthermore, participants completed questionnaires regarding resilience, access to social support, coping, and emotional distress. Descriptive statistics were applied, and Spearman Rho correlation coefficients were used to explore the relationships between psychosocial factors and emotional distress. Eleven exhibited normal cognitive functioning. An observed difference was seen between participants with and without hydrocephalus, where six and five persons reported clinical levels of depression and anxiety, respectively. Positive perceptions of self and future were associated with lower levels of depression and anxiety. This study adds important information about cognitive functioning and emotional distress in an understudied population. The results indicated normal cognitive functioning in adults aged 55 to 68 years with SBM without hydrocephalus. Prevalence of emotional distress was comparable with previous studies of younger adults with SBM. There is a need for longitudinal studies investigating cognition and psychological health to fully capture important aspects of the life course of SBM with and without hydrocephalus.
