Both books remain agnostic about the fundamental handicap or handicaps of Asperger syndrome yet contain substantial sections about helping these children. Inevitably, therefore, this advice tends to be unsystematic and anecdotal. Very little of the interventions described have an evidence base, and both books take a highly optimistic line about what can be done to help persons with Asperger syndrome that can sometimes seem unrealistic. It is these sections that parents will be likely to consult most often, and both books contain useful advice. The OASIS Guide seems a bit more realistic, as is befitting of a book that is informed by questions posed by parents themselves, and gives more direct advice about how parents can handle situations. Comorbid conditions get much better coverage in the OASIS book, which gives an excellent discussion of the pros and cons of methylphenidate and other medication.
