ADHD is associated with characteristic brainwave patterns. EEG studies show that many individuals with ADHD have increased slow-wave theta activity and reduced fast-wave beta activity in frontal brain regions responsible for attention and executive control.
This pattern is often referred to as an elevated theta/beta ratio, which correlates with distractibility and reduced cognitive control.
Neurofeedback targets these patterns by reinforcing more optimal brainwave activity. During training sessions, individuals receive immediate feedback when their brain activity moves toward desired patterns, allowing the brain to learn self-regulation.
A comprehensive review in Frontiers in Human Neuroscience describes how neurofeedback leverages operant conditioning to reshape neural oscillations and strengthen attention networks.

Early controlled trials demonstrated that training individuals to decrease theta activity and increase beta activity significantly improved sustained attention and behavioral regulation.

More recent studies suggest that neurofeedback may also enhance connectivity between frontal and parietal brain networks involved in executive function.
Through repeated training sessions, the brain gradually adopts healthier neural patterns that persist beyond the training environment.
