Subgroups of Attention Deficit Disorder (ADHD). A Preliminary Clinical Descriptive Study

Abstract

Attention deficit/hyperactivity disorder (ADHD) is a term used to describe a constellation of inappropriate levels of inattention and impulsivity. The history of name changes from minimal brain syndrome, to hyperkinetic syndrome, to what is now known as ADHD, reflects the influence of neurology, pediatrics, and psychiatry. This "evolutionary" process has been replete with controversy stemming from the diverse views of broad disciplines that have attempted to define its range, scope, and treatment [1]. According to Sell-Salazar [2]. There are two specific syndromes: a) Attention deficit disorder, without hyperactivity; b) A more complex syndrome, with hyperactivity, and traits of impulsivity, accompanied by attention deficit disorder.The etiology of this syndrome is still unclear, but there has been some hypothesis about hypo perfused areas in the frontal lobe, in some patients where PET has been available. There has been also some response to stimulants; which leads to the conclusion that there is some relation with neurotransmitters, like noradrenaline and dopamine, as a determinant factor in the origin of this process. The associated comorbidity most frequently associated with ADHD are: Tourette syndrome, generalized development disorders, learning disorders, coordination development disorders, behavioral disorders, anxiety disorders, affective disorders and mental retardation. Montiel Nava [3] reported a clinical presentation of attention deficit/hyperactivity disorder as a function of the gender. Attention-deficit/hyperactivity disorder
