The efficacy and safety of these medications in decreasing the symptoms of AD/HD is supported by extensive literature of controlled studies (up to 24 months of treatment).

It has been found that children who receive Ritalin are most likely not to have a substance abuse problem, where others turn to drugs by the end of their teens or early twenties to cope with the disorder. The classroom can be one of the most aggravating places for the ADHD student, his/her classmates, and the teacher. For the student, paying attention in class is a job in itself. The slightest sound or movement can distract the student without him realizing what happen. The physical arrangement of the classroom is very important to the ADHD student. Tables are more distracting than individual desks. Posters on the walls may look nice, but there needs to be at least some " white space" that is free of clutter. Seat the student near the teacher's desk, but include them as part of the regular class seating. Surround the student with good role models, preferably students whom they view as significant others. Bob Seay, the author of Teaching the AD/HD Student, list a few helpful tips on things that can be done to decrease distractions: Seat ADHD students in the front, middle of the room. Incorporate a variety of learning activities into your classes Be ready to repeat instructions Limit any kind of noise or activity so that it is less likely for ADD students to become distracted.
