Brain Training Helps ADHD Sufferers to Concentrate

A brain-training program developed for children diagnosed with ADHD has shown promise in its ability to reduce inattention and help children concentrate more effectively over the long term. 

A brain-training program developed for children diagnosed with ADHD has shown promise in its ability to reduce inattention and help children concentrate more effectively over the long term. 


A team of international scientists recently evaluated a specific piece of computer software called Cogmed, which was designed to improve "how much verbal or visual information you can temporarily remember and work with." Results of the analysis, which reviewed 11 other studies, are published at the online journal PLOS One.

Neuroscientists are currently debating how effective brain-training exercises can be in improving general qualities of the brain like attention and memory. Some argue that any cognitive improvements gained through memory games remain limited to exercises like recalling a sequence of images or digits. Cogmed also emphasized this skill:

"For example, you might be shown a string of words, and then be asked to recall them in reverse order. The program requires 35 minutes a day of training, five days a week for five weeks. It was developed for children with ADHD, but has been expanded to all people of all ages."

Common medical knowledge once held that cognitive function plateaued early in life, but more recent neurological research has found the brain remains "plastic" well into adult years. Princeton neuroscientist Sam Wang explains what is meant by neuroplasticity and how the term came about:

"A little over 50 years ago, a Canadian psychologist named Donald Hebb suggested the specific idea that experience could change the brain in ways that perhaps there’ll be some pathway that gets activated in an order of events that gets turned on when we experience something."

According to the PLOS ONE study, the Cogmed brain-training software performed at a higher rate of success than antidepressants.

"Cogmed reduced inattention by an 'effect size' of 0.47, says [Megan] Spencer-Smith. In educational interventions, an effect size of 0.25 is often treated as valuable, and many antidepressants are approved with an effect size of about 0.3."

But because such programs can be time-consuming and expensive, parents as well as medical professionals will likely await further studies that measure the performance of larger groups of people over longer amounts of time.

Could you give up complaining for a whole month? That's the crux of this interesting piece by Jessica Hullinger over at Fast Company. Hullinger explores the reasons why humans are so predisposed to griping and why, despite these predispositions, we should all try to complain less. As for no complaining for a month, that was the goal for people enrolled in the Complaint Restraint project.

Participants sought to go the entirety of February without so much as a moan, groan, or bellyache.
