Sleep Disturbances and Epileptiform Activity in a Subpopulation of Children with Attention Deficit Hyperactivity Disorder (ADHD): A Literature Review Generating an Hypothesis with Implications for Drug Therapy

Based on the available literature, we propose a hypothesis indicating four subtypes of ADHD. The usefulness of EEGs and sleep laboratory indices in detecting a subgroup of patients with submaximal responses to methylphenidate is also discussed
