Characteristics of early cognitive impairment after transient ischemic attack and mild ischemic stroke

Objective To investigate the neuropsychological characteristics of early cognitive impairment in patients with transient ischemic attack(TIA)and mild ischemic stroke by using the Montreal Cognitive Assessment-Basic(MoCA-BC)Cognitive Domain Index Score(CDIS).Methods A total of 86 patients with TIA or mild ischemic stroke were enrolled.Clinical data were collected and neurocognitive assessment was performed using MoCA-BC scale.Patients were divided into cognitive impairment group and no cognitive impairment group according to the MoCA-BC score,and the MoCA-BC CDIS were calculated with reference to the CDIS formula published.The clinical characteristics and MoCA-BC CDIS were compared between groups.Results Compared with the no cognitive impairment group,the patients in the cognitive impairment group were older,less educated and had a hypertension(P<0.05).The MoCA-BC Execution Index Score(MoCA-BC EIS),Memory Index Score(MoCA-BC MIS),Language Index Score(MoCA-BC LIS),Visual Spatial Index Score(MoCA-BC VIS),Attention Index Score(MoCA-BC AIS)and Orientation Index Score(MoCA-BC OIS)of the cognitive impairment group were significantly lower than those of the no cognitive impairment group(P<0.05).Conclusion Early cognitive impairment after TIA and mild ischemic stroke involves multiple cognitive domains,especially in the domain of executive and memory.
