The neuropsychological assessment consisted of the MicroCog Assessment of Cognitive Functioning (standard version) (Powell et al., 1993) supplemented by a number of additional tests (see (Fein et al., 2006) for a listing of all tests, references, and norms). Ten domain scores were computed based on these tests (see Fein 2006), and as noted above, LTAA only evidenced impairment in the spatial processing domain, scores of which are presented in Table 1.
