It is not uncommon to have a diagnostic evaluation be inconclusive. Because Asperger’s Disorder is based on clinical judgment, there are cases where one doctor will determine Asperger’s Disorder is present but another doctor will say it is not. Your child may be too young to determine if Asperger’s Disorder is fully present, or the symptoms may not be severe enough to warrant the diagnosis. Doctors differ on where they draw the line for diagnosing. This is not surprising and merely highlights the subjective nature of diagnosing this disorder. In fact, Asperger’s Disorder is one of the more commonly misdiagnosed disorders because its symptoms are not clear-cut and overlap with both normal behaviors and those of other disorders.
If your child’s evaluation is inconclusive, you may opt to obtain a second opinion with the same type of doctor who performed the first evaluation, thus having two opinions from two different psychologists. Alternatively, you may seek a different category of specialist, thus having an opinion, for example, from one psychologist and one psychiatrist. Or as many parents do, you can simply choose to have your child treated for the various problems he exhibits and wait to see if the diagnosis becomes clearer over time.
