ADHD is a highly comorbid disorder in patients with substance use disorders (SUD). This comorbid patient population is, however, often undertreated. Diagnosing ADHD in patients with SUD is not easy due to the large overlap of the ADHD characteristics with symptoms of intoxication and withdrawal.These patients often disappear prematurely from the treatment services, on the one hand because their untreated ADHD symptoms make it more difficult to follow the therapy, on the other hand because the treatment programs do not take their limitations into account. Caregivers expressed a great need for concrete tools to work with these patients. Therefore, “Managing ADHD in the presence of substance use disorders” consists of a theoretical and a practical part. The different aspects of the treatment are described from various therapeutic perspectives, and elaborated in ten modules with downloadable worksheets.“This is a practical and insightful book that I highly recommend to both novice and experienced clinicians alike.” Frances R.
