Abstract:
Objective To evaluate the cognitive dysfunction and its influential factors in patients with symptomatic and asymptomatic lacunar infarction(LI). Methods Mini-mental state examination (MMSE), MoCA and P300 were carried out among 70 patients with first attack of LI 1 week after, 66 patients with asymptomatic LI and 54 patients for control at first visit. The tests were performed again in the follow-up of half a year and one year. Results (l)The scores of MMSE and MoCA at 1 week, half a year and one year of LI at acute stage were lower than asymptomatic LI(P＜0. 01) and control group(P＜0. 01). Latent periods of P300 at each time point were longer than those in patients with asymptomatic LI (P＜0. 05) and control group (P＜0. 01). (2)The scores of MMSE and MoCA at first visit, half a year of follow-up and one year of follow-up in patients with asymptomatic LI were lower than those in control group(P＜0. 01), and the latent period of P300 was longer than that in control group(P＜0. 01). (3)The scores of MMSE and MoCA at 1 week of LI at acute stage and first visit of asymptomatic LI were higher than those after one year(P＜0. 05). The latent periods of P300 were shorter than those after one year(P＜0. 05). Compared with those half a year after, MMSE and MoCA one year after decreased more and the latent period of P300 prolonged(P＞0. 05). (4) The scores of MoCA in the aspects of visuospatial and executive function, abstract thinking and attention were lower than those in control group (P＜0. 01). (5)The score of MoCA in LI patients with multiple foci was lower than that in LI patients with single focus(P＜0. 01). The scores of MoCA in patients with foci in basal ganglia, frontal lobe, temporal lobe and thalamus were lower than those in patients with foci in other parts (P＜0. 01). Conclusion LI (both symptomatic and asymptomatic) is easily accompanied with cognitive dysfunction. The cognitive damage becomes more severe as time prolongs. The common symptoms include damages of visuospatial and executive function, abstract thinking and attention. Patients with multiple foci and with LI in key parts easily suffer from cognitive dysfunction. Thus, it needs to evaluate and prevent early.
