Correlation between Type D personality and white matter hyperintensities in patients with cerebral small vessel disease / 国际脑血管病杂志

ABSTRACT

Objective:To investigate the correlation between the Type D personality and the severity of white matter hyperintensities (WMHs) in patients with cerebral small vessel disease (CSVD).Methods:Consecutive patients with CSVD admitted to the Changzhou First People's Hospital between November 2020 and June 2021 were enrolled prospectively. The patients were scored on the Type D Personality Scale at admission; the scores of negative affectivity (NA) and social inhibition (SI) dimension were calculated respectively. The general data, laboratory examination data and imaging data of the patients were collected. Periventricular and deep WMHs were scored using the Fazekas visual scoring method. The total score 0-2 was defined as low-WMHs (L-WMHs), and 3-6 was defined as high-WMHs (H-WMHs). Multivariate logistic regression analysis was used to determine the independent influencing factor of WMHs. Results:A total of 100 patients with CSVD were enrolled, including 51 males (51%), aged 67.21±9.38 years, 29 (29%) had Type D personality; 56 (56%) were in the L-WMHs group and 44 (44%) were in the H-WMHs group. Univariate analysis showed that the proportion of Type D personality, NA dimension score, the proportion of hypertension, diastolic blood pressure, triglyceride and homocysteine in the H-WMHs group were significantly higher than those in the L-WMHs group (all P<0.05). Multivariate logistic regression analysis showed that NA dimension score (odds ratio [ OR] 18.351, 95% confidence interval [ CI] 2.780-121.135; P=0.003), age ( OR 1.134, 95% CI 1.039-1.238; P=0.005) and hypertension ( OR 7.771, 95% CI 1.525-39.607; P=0.014) were significantly positively correlated with the severity of WMHs, while triglycerides were significantly negatively correlated with the severity of WMHs ( OR 0.306, 95% CI 0.130-0.722; P=0.007). Conclusion:Type D personality is closely associated with the severity of WMHs in patients with CSVD.
