This landmark neuro-review tracks how specific movement profiles physically alter brain mechanics in children and adolescents. Rather than a vague health recommendation, the data isolates exactly how structured exercise repairs executive function deficits by acting on the same neural pathways targeted by traditional psychostimulants.
