Light up ADHD: II. Neuropharmacological effects measured by Near Infrared Spectroscopy: is there a biomarker?

Attention-deficit/hyperactivity disorder (ADHD) is one of the most frequently diagnosed neurodevelopmental disorders in childhood, and its worldwide prevalence among children and adolescents is about 5% (Faraone et al., 2015). ADHD's heterogeneous phenotypes are characterized by inattention, excessive motor activity, and high levels of impulsivity (American Psychiatric Association, 2013); these symptoms seem to arise from neurotransmission dysregulation or insufficient production of catecholamines within the prefrontal cortex (PFC) and subcortical regions (Arnsten, 2006; Del Campo et al., 2011).
