The AACN website (www.theaacn.org) has a section called Papers/Policies/Research.
In it you'll find this wonderful document that clearly and succinctly describes the indications for neuropsychological assessment and contraindications for neuropsychological assessment across the lifespan. It includes supporting references, and clearly argues for feedback to be included in the neuropsychological assessment.
While the US Medicare codes aren't entirely relevant to the Australian context, the other text in the document is fantastic, and should be quoted by any neuropsychologist who wants to explain the scope of our practice, and the evidence for its utility in different disorders, including disability and non-CNS disorders.
Congratulations to Michelle Braun, Teresa Deer, Paul Kaufmann, Karen Postal, David Tupper, Michael Westerveld, and Karen Wills for producing this excellent document on behalf of the American Academy of Clinical Neuropsychology (AACN), the American Psychological Association (APA) Division of Neuropsychology, and the National Academy of Neuropsychology (NAN).
