Primary | Change in cognitive function | We measure the cognitive function of children by means of a battery of tests including: stroop test, Continuous Performance, digit span, digit signal and digit selection. We combine the computer tests with eye tracking to provide information about saccadic gain during the tests. The computer tests provide data on how much time per reaction (msec) was needed or how many digits could be remembered. | At the baseline, after 6 months and through study completion, an average of 1 year | |
Primary | Change in wellbeing | We measure the emotional wellbeing by means of the Kids screen test that builds a score of 27 points. | at the baseline, after 6 months and through study completion, an average of 1 year | |
