Currently, Attention Deficit Hyperactivity Disorder (ADHD) is estimated to affect 2.5% of adults, about 3 to 7% of school-age children (6-12 years) worldwide, and in More than 68% of cases the disorder lasts for life. Considering these numbers and the high prevalence of ADHD, the main purpose of this book is to make accessible a variety of instruments (Scales, Tests, Questionnaires, Diagnostic Criteria, Screening, etc.) that enable a better assessment of the existence of the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) in children, youth and adults. However, by no means do the resources available here - albeit of great value - have the character of asserting any diagnosis. It is noteworthy that the diagnosis of ADHD is strictly clinical, and no single tool replaces the thorough analysis performed by a specialized professional.With regard to the constant news that casts doubt on the truth of the existence of ADHD, the book also soberly refutes these controversies, presenting compelling arguments. In addition, the book also features a list of celebrities diagnosed with ADHD and exciting testimonials from several people equally diagnosed with the disorder.It is also important to highlight that - because much of the content of this book has been translated from other languages possibly some expressions and / or excerpts appear to be slightly inaccurate and / or ambiguous in language.
