Training of slow cortical potentials in attention-deficit/hyperactivity disorder: evidence for positive behavioral and neurophysiological effects.

Learned self-control of slow cortical potentials (SCPs) may lead to behavioral improvement in attention-deficit/hyperactivity disorder (ADHD). Hence, training effects should also be reflected at the neurophysiological level.


Thirteen children with ADHD, aged 7-13 years, performed 25 SCP training sessions within 3 weeks. Before and after training, the German ADHD rating scale was completed by parents, and event-related potentials were recorded in a cued continuous performance test (CPT). For a waiting-list group of nine children with ADHD, the same testing was applied.


ADHD symptomatology was reduced by approximately 25% after SCP training. Moreover, a decrease of impulsivity errors and an increase of the contingent negative variation were observed in the CPT task.


This study provides first evidence for both positive behavioral and specific neurophysiological effects of SCP training in children with ADHD.
