Background and aims: Being born preterm with ELBW (birth weight < 1000g) constitutes an increased risk of learning disabilities and psychiatric symptoms, including attention deficit and working memory (WM) problems. WM is our ability to hold visual and/or verbal information online while manipulating it (i.e. doing mental arithmetic). Aim of study was to evaluate the effect of daily use of a computerized WM training program (Cogmed RM) in ELBW adolescents compared to controls. We assessed verbal and visual aspects of WM as well as generalizing effects on learning.Methods: Sixteen ELBW and 19 controls age 14-15 participated in a study from St. Olav's University Hospital in Trondelag, Norway. The control group consisted of term born children with normal birth weight. An extensive neuropsychological assessment was performed prior to, immediately after training, and at 6 months follow up. Participants used the Cogmed RM computer program at home for 30 minutes a day, 5 days a week in 5 weeks.Results: Before training the ELBW subjects obtained lower IQ scores and lower scores on visual WM, as well on delayed memory for a verbal story. Both groups significantly improved their WM results on visual and verbal WM tasks, and obtained better results on non-trained tasks measuring learning ability for verbal material. After training there were no significant differences between groups on any outcome measurements. Six months follow up showed sustained effects of training.Conclusions: Computerized WM training may be an effective intervention to reduce learning and memory deficits in ELBW adolescents. |
