ADHD (attention deficit hyperactivity disorder) is a psychological disorder subject to ethical questions in its treatments through the use of methylphenidate otherwise known as Ritalin, Ritalin is the current main form of drug treatment for Attention Deficit Hyperactivity Disorder (ADHD), and the last decade has seen a dramatic increase in the rate of prescription, which has raised some ethical questions with its prescribing. There is currently no biological basis for ADHD diagnosis results when doctors make their diagnoses based on behavioral symptoms such as hyperactivity and inability to concentrate. Considering that these symptoms are behaviors that anyone can express at a certain time in their life, the risk of overdiagnosis of the disease increases. This could subsequently lead to overprescribing of Ritalin. Diagnosis of ADHD is particularly difficult in young children as its symptoms are based on judgments of behavior compared to other children describing "normal behavior", however ADHD symptoms can be seen as normal behavior for children as It is normal for some children to be hyperactive. A review of prescription data for 300,000 children aged 19 and younger showed that, for the first time in history, spending on drugs for childhood behavioral problems was higher than spending on any other category of children's drugs, including medications such as antibiotics. This evidence raises concerns about the possibility of Ritalin and its overprescription for ADHD, especially in children since the disorder is primarily observed in childhood. The definition of ADHD is still a matter of debate and it has been observed that the diagnosis of the disease increases as the diagnostic criteria change, thus leading to overdiagnosis. In psychotherapy the psychologist must ensure that there is a high level of trust between him and the patient. There must also be a high level of confidentiality between both parties. Only at necessary times should the patient's medical record be disclosed to third parties. Boundaries must also be established between the patient and his psychologists and there must not be any form of sexual interaction between either party. In terms of drug treatments with patients suffering from ADHD, the over-prescription of Ritalin needs to be reviewed as more and more young children are forced to take the drug which often leads to the child losing personality freedom. These ethical issues need to be examined as these drugs are given to children so that they can adapt to a socially normal behavioral society which in turn makes them subject to discrimination.
