ABSTRACT
Chapter 14 includes six clinical cases presented by experienced clinicians. These cases represent almost the whole range of ADHD spectrum, across the two sexes, developmental stages, and comorbid disorders. Our purpose is to illustrate the implementation of the multilevel approach in the treatment of ADHD. In this chapter, the basic principles of theories of ADHD are integrated in treatment and turned into practice to result in effective management of the disorder. Finally, we illustrate how clinicians with coherent, integrated, and multifaceted theoretical knowledge, relevant clinical experience, and certain personality characteristics may make the difference between effective and ineffective use of methods and strategies.
