Ritalin is a Ciba Geigy’s proprietary name for the drug Methyl Phenidate Hydrochloride, also known under other proprietary names in certain countries, including methidate, rilatine, rubifren, aktilin and centedrin. In this text, the author authoritatively debunks misguided opinions and misconceptions surrounding the use of ritalin - problems and pitfalls in diagnosis and treatment, expectations, limitations, and precautions. He also explains medical considerations of Attention Deficit Hyperactivity Disorder (ADHD) and learning disabilities in non-technical language. This book should be of interest to parents, teachers, and practitioners working with those with learning difficulties and challenging behaviours.
