Northwestern Anagram Test-Italian (Nat-I) for primary progressive aphasia.

ABSTRACT:

Objectives

To test the ability of the Northwestern Anagram Test-Italian (NAT-I) to distinguish between the non-fluent/agrammatic (nfv-) and phonological/logopenic (lv-) variants of primary progressive aphasia (PPA), and to determine the relationship between NAT-I variables and brain integrity in PPA patients.

Methods

13 nfvPPA and 8 lvPPA patients underwent the 44-item-version of NAT-I and brain MRI. The NAT-I was also administered to six patients with the semantic variant (sv) PPA to sample performance in cases with no grammatical deficits. Performances were recorded and compared between patient groups. Receiver Operating Characteristic curve analysis assessed the ability of NAT-I to discriminate nfvPPA and lvPPA. The correlation between anatomical changes and NAT-I variabl
