Brain electrical activity mapping in the diagnosis of attention-deficit hyperactivity disorder

Authors

Abstract

Background
Attention-deficit/hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder of childhood. It affects approximately 4% of all children, although estimates vary widely from 3% to 11% or more. Neuroimaging and neurophysiological tests have been increasingly used to understand the relation between brain functionality and ADHD symptoms. QEEG provides a method that can measure the neurophysiological mechanisms underlying neurodevelopmental disorders. By using spectral analysis is able to find abnormalities of brain functionality and connectivity linked to abnormal ADHD behaviors.
Methodology
The current study was conducted on 60 school aged children range from 6-15 years (60 ADHD children matching DSM-5 criteria) and 20 typically developing children. All cases were subjected to thorough history taking and clinical examination with special attention to neurological examination. Both cases and controls were subjected to QEEG analysis and interpretation. All studied children had undergone assessment with Arabic form of Conners’ Parent Rating Scale short form, IQ test, Arabic version of DSM-5.
