ADHD Meds Improve Alertness, Not Focus, Study Finds
A new study found that medicines used to treat ADHD, like Addwise, work by making people more alert and interested in tasks, not by directly improving their focus.
Researchers looked at brain scans of nearly 5,800 children and found that these medicines affect the parts of the brain related to rewards and wakefulness.
This helps children with ADHD stay more engaged in tasks they might otherwise find boring.
The study also showed that these medicines can help children with ADHD get better grades and perform better on tests.
However, the medicines didn't help neurotypical kids who get enough sleep.
The researchers suggest that addressing sleep problems is also important for children with ADHD.
ADHD stimulant medications improve alertness and interest in tasks, not direct focus.
Study analyzed fMRI scans of 5,800 children aged 8 to 11.
Medications affect brain regions related to reward and wakefulness, not attention.
Stimulants mimic effects of good sleep, negating sleep deprivation effects.
Children with ADHD who took stimulants had better grades and test performance.
