A Double-Blind Randomized Pilot Trial Comparing Computerised Cognitive Exercises to Tetris in Adolescents With Attention-Deficit/Hyperactivity Disorder

The purpose of this study was to examine the feasibility and efficacy of computerized cognitive exercises from Scientific Brain Training (SBT), compared to the computer game Tetris as an active placebo, in a pilot study of adolescents with Attention-deficit/hyperactivity disorder (ADHD).
