After many years of research, we still don’t know which treatments are most effective for which children -- or whether one treatment is more effective than another. Behavioral interventions are the best-researched treatments for autism, but even top scientists acknowledge that developmental interventions may or may not be equally useful for any given child. Meanwhile, only two drugs -- Risperdal and Abilify -- have been approved for use with children on the autism spectrum, and neither addresses “core” issues of autism (social/communication deficits).
