Alzheimer\u2019s disease (AD) and AD associated with a significant vascular component were the diagnoses more frequently related to cSS (18\/26; 69%). Patients with cSS had an increased prevalence of both hypertension (81% versus 57%; p\u200a=\u200a0.015) and WMH burden ( p\u200a=\u200a0.012). The overall prevalence of cerebral microbleeds (69% versus 32%; p\u200a&lt;\u200a0.01), as well as their mean number (0.69\u00b10.47 versus 0.32\u00b10.46; p\u200a&lt;\u200a0.01) were both increased in patients with cSS. In the logistic regression model, the presence of 5 or more CMB (OR 11.35; 95% CI 4.68\u201327.55; p\u200a&lt;\u200a0.01) and hypertension (OR 3.31; 95% CI 1.19\u20139.15; p\u200a=\u200a0.021) were
