IntroductionAttention deficit hyperactivity disorder (ADHD) is a common neurobehavioral disorder in children and adolescents that can lead to increased levels of hyperactivity, inattention, and impulsivity not normal. Children with this condition are very likely to present symptoms even when they are adolescents, and adolescents with ADHD are in turn at high risk of functional impairment which can have serious consequences on their quality of life. In general, children and adolescents with ADHD also face a higher risk of developing other psychiatric illnesses. [1]Methylphenidate (MPH), which goes by the trade name Ritalin™, is, among other indications, one of the main medications prescribed for ADHD. MPH evokes pharmacological pathways and psychotropic effects similar (but not identical) to those produced by cocaine and amphetamines. The drug has been prescribed and administered safely for over forty years, but has recently attracted attention and raised questions about its wide use among students studying for exams without a medical or psychiatric diagnosis. It has been found that its use can even be encouraged by parents and guardians. The use of ADHD medications without a prescription, also called nonmedical use, is well documented. It is characteristic that in the United States, in schools with very competitive admission standards, prevalence rates can even exceed 20%. [2] Method Selection The scope of this report is to suggest the most appropriate method by which the reasons and motivations behind the use of Ritalin™ beyond its formal therapeutic indication can be identified. Therefore, the purpose of this method will be to clarify why students use ADHD without prescription, in...... full paper...... ns should depend on the conditions and subject of the study and not be biased on the part of the researcher. Second, the reliability, reliability and verifiability of the results which concern the quality of the research, which had to be consistent and stable over time and between different researchers and methods. In addition, the internal validity, credibility and authenticity of the results which must be meaningful, must be credible and have an authentic portrait. Furthermore, the external validity, transferability and adequacy of the findings focus on whether the results are transferable to other contexts, to what extent they have greater importance and to what extent they can be generalized . Finally, many relevant queries can be used as criteria to guarantee the results of the research project.. [12]
