Abstract:
Objective To compare the ability of auditory verbal learning,memory and retention between each side of thalamus and basal ganglia after stroke.Methods 63 patients with single lesion in thalamus or basal ganglia after stroke,34 patients with amnestic mild cognitive impairment (aMCI)and 34 healthy control subjects received auditory verbal learning test.Results There was an overall decline of immediate and delayed recall,retention ability in patients with single lesion of stroke as compared with the healthy control group(P＜0.05).Both the left thalamic stroke group [(19.0± 3.1)scores]and aMCI group[(17.6 ±3.3)scores]showed similar pattern in damaged recognition ability,while this ability still existed in the other three stroke groups.The ability of auditory verbal learning in the left thalamic stroke group[(2.2 ± 2.0)scores]and right thalamic stroke group[(2.1 ± 1.9)scores]were lower than in the healthy control group[(3.6 ± 1.8)scores](P ＜0.05).The retention ability in the left thalamus stroke group[(2.8±1.7)scores]and the right basal ganglia stroke group[(2.7 ± 1.9)scores]was decreased than in the healthy control group[(1.7±1.4)scores](P＜0.05).Conclusions There is decline of AVLT-learning,memory and retention ability in patients with single lesion stroke,especially in the left thalamus stroke patients.Moreover,the pattern of impairment in the left thalamus stroke is similar to aMCI but different from the other three stroke groups.
