Why are there so many unsubstantiated treatments in autism?

Abstract: The number of interventions used in the field of autism is astronomical. Unfortunately, while there are effective and well-researched methods, many of the techniques that parents use have no empirical support. These interventions are expensive, take up valuable time, and in some cases are dangerous. How bad is this problem, how did the field get here, and what are potential solutions? This review covers this important but infrequently discussed topic. [Copyright &y& Elsevier]
