Reflecting tremendous gains over the past decade in our understanding of the causes of autism, Clinical Manual for the Treatment of Autism meets the increasing need for clear, up-to-date, and evidence-based treatment. Internationally known researchers who are also skilled in treating patients with autism share treatment approaches they have either developed or thoroughly tested for safety and efficacy. The book describes in a straightforward manner how to diagnose autism, providing examples and guidelines for evaluation and testing of individuals of all ages and levels of functioning. It then evaluates the appropriate role of various medications for specific target symptoms and individuals: SSRIs and antidepressants, anticonvulsants and mood stabilizers, conventional and atypical antipsychotics, cholinesterase inhibitors, and stimulants and nonstimulants. In addition to pharmacological approaches, the book presents psychosocial treatments, including applied behavior analysis, the DIR/Floortime approach, peer relationship interventions, and educational approaches. It also describes complementary and alternative therapies and explores promising new avenues of treatment, making it a state-of-the-art compendium that will help advance the care that people with autism receive.
