What is the Meaning & What is ad

The acronym ad refer to the following concept: attention deficit disorder. It is a disease that mainly affects children and that disrupts the learning process and social behavior.

General characteristics of the TDA

There are children who have some patterns of behaviour that deviate from the conventional behavior: constant interruptions, talking excessively, inability to be quiet and, in short, a hyperactivity that can not control. These behaviors are problematic for the socialization of the child and their school performance. The main feature of this disorder is precisely a lack of attention. The ad tends to be accompanied by a H of hyperactivity, indicating that insufficient attention is normally associated with agitation and the alteration in the daily activity.
This disorder is more common in boys than girls (four times more in the male population) and is usually detected beginning at age seven. One can distinguish three types of ad depending on the prevalent symptoms:
1) inattentive subtype which is dominated by the attention deficit,
(2) the hyperkinetic subtype or increase impulsivity and
(3) a mixed subtype which is combined inattention with a behavior excessively active.
On the other hand, according to recent studies by 8 to 10% of the child population does this behavior disorder.


The knowledge of brain functions has allowed to know quite precisely some of the reasons that explain the ad or ADHD. His neurobiological Foundation relies on an alteration of dopamine. Dopamine is a neurotransmitter that controls a section of brain activity and which is involved in the search for the pleasure of the individual. This neurotransmitter is associated with motor functions of the body, with the reward system and control of hormones. As a result, an alteration of dopamine levels makes that the individual has a disorder in his behavior.


When the Add or ADHD is unknown, children with attention deficit and hyperactivity were considered as restless children or even with intellectual retardation. Fortunately, the knowledge of the human brain has made it possible to understand the mechanisms of this disease and, at the same time, how can be treated. Experts recommend a combination of psychosocial treatments and pharmacological. Medicines to combat the TDA acting on the brain chemistry and can reduce uncontrolled levels of dopamine. Psychological therapies are going online to promote behavior appropriate using positive reinforcement (for example, rewarding correct answers), as well as techniques of self-control and problem solving-oriented.
