Prescription medication for ADHD might not affect the attention networks of the brain, according to international researchers. The team looked at brain imaging data of kids aged 8-11, and found that taking these ADHD medications, which are stimulants, instead improve brain performance by reversing the effects of sleep deprivation on brain connections and school grades. They also found brain connectivity changed in the parts of the brain associated with wakefulness and reward, but not the brain’s attention systems. The team says their findings imply the ADHD medications might drive brain organisation towards a more wakeful and rewarded configuration, improving task effort and persistence without effects on attention networks.
Anyone able to explain what the resulting consequences mean in practice?
