I have a son who is high functioning autistic. He has benefited greatly by his training at learning Rx. I have researched cognitive development and Learning Rx seems to implement the principles needed for cog improvement the most effectiviely. Three elements need to be present to increase those brain pathways....intensity, duration, and frequency. In my research learning Rx does these things the best. I have loved my experience there and my son loves it also and feels great after 18 weeks.
