Among the most complicated mysteries of the universe and human nature, the question concerning the way in which a human brain or, to be more exact, human nervous system, works seems to be the hardest to answer. Despite the fact that in the present-day world, a lot of complicated questions in the sphere of medicine have been answered successfully, the question concerning whether a certain specific state should be considered a disorder or merely a specific state of mind, remains open. Among the above-mentioned states, the phenomenon known as ADHD, or Attention Deficit Hyperactivity Disorder, deserves to be mentioned. Because of the fact that most children, as the results of numerous researches show, have ADHD at certain stages of their development, the classification of the phenomenon as a disorder is questioned (Wright, 2012). Checking the latest research results on ADHD and comparing them to the previous records, one can possibly find out whether ADHD is an actual disorder or merely specifics of most children’s development. To start with, the key symptoms of the disorder in question must be named. However, even at the very first stage of defining the key features of the disorder, one must admit that the existing descriptions of the symptoms are rather vague. According to the existing evidence, the children with ADHD tend to display such negative qualities as “inattentiveness, forgetfulness, hyperactivity, and impulsivity” (Seitler, 2011, 116). Likewise, in the case study in question, the patients displayed similar symptoms, as Nelson, Duncan, Peacock and Bui (2012) say. Analyzing the above-mentioned, one must admit that the above-mentioned qualities can be discovered in children of a certain age quite often. Another essential detail of the case study in question, the background of the patients is rather important for understanding the mechanisms of the phenomenon. According to the research design offered by Nelson, Duncan, Peacock and Bui, the settings of the research and the patients’ background were the following: “The ADHD Telemedicine Clinic served English- and Spanish-speaking families for a half-day/week while school was in session, with initial intake slots of 90 min” (Nelson, Duncan, Peacock and Bui, 2012, 294). Hence, it can be concluded that the research was carried out among the children who were under a considerable pressure in school as the representatives of minority, which could have been the reason for the rapidly developing symptoms of the alleged disorder. As it has been mentioned above, the children who have been observed in the given case study have experienced certain issues which must have had an impact on their development and, therefore, served as the causes of the ADHD phenomenon. To start with, the children in the case study have very specific background – according to the case, they are all belong to the cultures of the national and social minorities, which makes their process of integration into the society all the harder. According to the case study settings, the children whose behavior was observed came from the English- and Spanish-speaking families with other than American backgrounds. Since there are still considerable arguments against adding the ADHD to the
