State of the art and new directions of Quantitative Electroencephalography use in Differential Diagnosis of ADHD

Advances in technology in recent years have made the use of quantitative electroencephalogram more accessible to clinicians. The incorporation of normative databases in QEEG studies and the possibility of detecting different electroencephalographic patterns in patients with a given pathology, despite showing an apparent symptomatology homogeneity, make it an interesting source of information. The relationship of these patterns with a possible response to treatment or with prognostic estimates would justify its inclusion as a routine test in the process of the differential diagnosis of ADHD. In this paper, we present the possible benefits of the use of QEEG in the differential diagnosis of ADHD, the different electroencephalographic patterns associated with ADHD most common in the literature, and a case showcasing the use of the technique in a patient with ADHD
