Methods Cognitive functions of 59 Chinese patients with aphasia following a stroke were assessed with the Chinese version of the second edition of LOTCA battery and their linguistic functions were tested with the Western Aphasia Battery (WAB) Scale

respectively. The Results of LOTCA were analyzed and compared across different groups

in the light of gender

age

educational background

the length of illness

and the degree of aphasia.Results Neither the score of subtests of the LOTCA nor the overall scores of LOTCA of aphasia patients with different gender and educational background differed (all P>0.05). In different age groups

apart from thinking operation (F=3.373

P=0.016)

visuomotor organization (F=3.124

P=0.022)

attention (F=3.729

P=0.009) and the total score (F=2.683

P=0.041)

there was no difference in terms of the other subtest scores of LOTCA (all P>0.05). In the groups of different length of time with illness

apart from orientation (F=2.982

P=0.039) and attention (F=3.485

P=0.022)

the score of other subtests and the total score of LOTCA were not different (all P>0.05). In the groups of different degree of aphasia

apart from attention (F=2.061

P=0.074)

both the score of other subtests and the total score of LOTCA differed (all P<0.05).ConclusionLOTCA might be suitable to assessing the cognitive ability of post-stroke Chinese patients with aphasia.
