Abstract:Objective To study the effect of emotion on cognitive function in patients with anxiety. Methods From January 2013 to May 2015, 98 first-episode patients with anxiety were enrolled as observation group, and 98 normal controls were investigated as control group. Hamilton anxiety scale (HAMA), Hamilton depression scale (HAMD), and Montreal cognitive assessment scale (MoCA) were performed to evaluate anxiety, depression, cognitive function respectively. Baseline data and scores of HAMA, HAMD, MoCA were compared between two groups. Pearson correlation analysis and multiple linear regression analysis were used to explore the influence factors of cognitive impairment for patients with anxiety. Results The scores of HAMA and HAMD in observation group were significantly higher than that in the control group (P < 0.05). The scores of visual space and executive function, attention, abstraction, directional and total score of MoCA in the observation group were significantly lower than that in the control group (P < 0.05). Pearson correlation analysis showed that MoCA total score was negatively correlated with HAMA score (r = 0.217, P = 0.217 < 0.05) and HAMD score (r = 0.228, P = 0.228 < 0.05) in observation group. Multiple linear regression analysis results showed that age, HAMA and HAMD scores were enrolled for the final equation, and they all had negative correlation with MoCA total score(P < 0.05). Conclusions The severity of anxiety and depression in patients with anxiety are associated with cognitive impairment, and depression may be the main factor.
