Approaches to Neuropsychological Assessment

Probably the most useful model of neuropsychological interpretation is described in Reitan and Wolfson's (1993) four approaches to assessment which are given below:

i) Level of performance,

ii) Pathognomonic signs,

iii) Pattern of performance, and

iv) Comparison of the left and right sides of the body.

The last approach can also include comparisons between the anterior and posterior parts of the brain, or between cortical and sub cortical structures, but our knowledge base remains strongest for right versus left comparisons.
