Attention Deficit Hyperactivity Disorder : an overview

Abstract

Attention Deficit Hyperactivity Disorder (ADHD) is a neurobehavioural disorder found more commonly, but not exclusively, in school-age children. The hallmarks of the condition are inattention and hyperactivity/ impulsivity, which often go together. Although the term ADHD was coined relatively recently, ADHD has in fact been described as early as 1902. This review article will go through the most important historical aspects of the condition, and will also give an account of what is known about the aetiology of ADHD. The diagnostic criteria issued by the American Psychiatric Association in DSM-5, have been last updated in May 2013. This article will highlight the differences between DSM-5 and the previous version, DSM-IV-TR, and will also touch upon the latest developments in electroencephalographybased investigations and imaging studies for ADHD. Although the condition cannot be cured, symptoms can be managed using various modalities such as behaviour intervention strategies and medication, such that the individual affected by ADHD can have the least possible disruption to social and academic functioning.peer-reviewe
