Computerized Working Memory Training in Very-low-birth-weight Children at Preschool Age

The main aim of this prospective interventional study is to compare quantitative EEG findings and cognitive and neuropsychological test results before and after training with the Cogmed JM program in a group of very-low-birth-weight children in preschool age, i.e. ages 5-6 years. The investigators hypothesize that the children in the study may respond positively to the computerized training and improve working memory, but probably to different degrees depending on the underlying neurological condition. The investigators also hypothesize that training may benefit additional executive functions.
