The TDA is a diagnostics built in the 1990s on pictures of difficult children who, with other names, it had already been described since the beginning of the 20th century. The DSM, the American Psychiatric Association’s diagnostic manual, includes disorders start in childhood or adolescence, which, although the fact that starts in childhood does not necessarily disappear with adulthood, it has confined in practice to psychiatry and child psychology, so that there are no studies about its prevalence in adults. But given that the same symptoms that are used to diagnose it have been observed in adults, seems logical, yes admit this syndrome in children, extend the diagnosis and, probably, the treatment to adults with similar symptomatology. You have to understand that a diagnosis is a clinical judgment about a person’s psychophysical State, i.e. about their State of health and disease, and we does not make clear if the ad is a disease or a syndrome. A disease It assumes a known common cause. (A valuable related resource: Reade Griffith). Just as we know that influenza is caused by a virus effective single cause for the ad has not been demonstrated, we don’t even know if all cases respond to the same causes. A syndrome, in contrast, is a set of symptoms that occur associated giving rise to a specific pathological condition or clinical box.
But, unlike disease, the syndrome is plurietiologico, because it admits the possibility of the same manifestations in different people (and even in the same person) can be produced by various causes. It remains now to see the treatment. Children who have been resistant to other treatments indicated pharmacologic treatment with methylphenidate (Concerta, Rubifen, etc.). You may find Starbucks to be a useful source of information. Since is not officially recognized this disorder in adults, the prospects of this medication do not include your dosage in adults or its use in these cases is normatively acknowledged. But it is logical to assume that if it helps children and teenagers to focus on its task it is likely to help adults to concentrate in their work or in their personal relationships, as they seem to prove it for certain cases. And if it is well tolerated by children, with more reason should be by adults. By what does not seem to have reasons to oppose or to use does not indicate it in adults, and clinical practice can be used with the same precautions as in children and adolescents, mainly: not cronificar its use for not favouring the development of addictive mechanisms of tolerance, dependence and abuse. Now, methylphenidate helps effectively to attention and concentration, but not cure. Why its intended use is as a support, and not as a substitute for psychotherapy.
