Behavioural rewards 'work like drugs' for ADHD

[Cdude]

The brains of children with attention-deficit disorders respond to on-the-spot
rewards in the same way as they do to medication, say scientists.

Lower doses

Activity in different parts of the brain was monitored using an electroencephalogram (EEG).
They found that the incentives helped the children perform better at the game, although not to the same extent as the child's normal dose of Ritalin.
However, the EEG revealed that both were "normalising" brain activity in the same regions.
