This is an exciting study, and we hope it will be replicated on a broader scale. Unfortunately, we can only provide a link to the abstract because we access the paper through the University of Washington. This Swedish study found that children diagnosed with ADHD, but never treated with medication (stimulants, atomoxetine, etc.) were able to improve their verbal working memory, timing and accuracy on Stroop tests, and complex reasoning, and reduce symptoms of inattention and hyperactivity / impulsivity with computer-based training (Robo-Memo) that included remembering the position of objects, remembering phonemes, letters, or digits. Training was adjusted to continually challenge children, and duration of training usually amounted to about 40 minutes per day for over 20 days.
There are some commercially-based computer programs based in the States, but the ones we have been able to sample were too simple for most of the children we see. Working memory is highly trainable, but the exciting aspect of this study is that the behavioral and inattentive symptoms also subsided as working memory increased.
