Neurometrics, dynamic brain imaging and attention deficit hyperactivity disorder

Objective: The literature on the development of frequency analysis of the electroencephalogram (neurometrics) and functional dynamic brain imaging techniques is reviewed. Clinical applications in the diagnosis and treatment of learning disorders of childhood are discussed. Conclusions: While questions remain about the sensitivity and specificity of the neurometric method in diagnosing attention deficit hyperactivity disorder (ADHD), if the technique proved predictive of medication response, its importance would be established. However, evoked-potential studies, cerebral blood flow and cerebral glucose metabolic studies promise a better understanding of underlying psychological processes in ADHD.
