RESUMEN
Small vessel disease (SVD) of the cerebral white and central grey matter is an important subtype of vascular dementia (VD).SVD-dementia is characterized by a dysexecutive type of cognitive impairment,neurological deficits including imbalance and voiding dysfunction,and emotional disturbances.SVD is also frequent among clinically healthy subjects and patients with mild cognitive impairment.It is easily visualized by imaging techniques,but difficult to distinguish from mixed SVD/ Alzheimer Disease.This article reviews the recent progress in research on SVD and the problems have to be resolved.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the characteristics of erectile dysfunction (ED) in old males with lacunar infarction.</p><p><b>METHODS</b>A total of 38 old patients ages from 60 to 70 years were involved. The questionnaire of international index of erectile function 5 (IIEF -5) was used to determine the status and severity of ED. According to the focus of infarction on MRI, the patients were divided into two groups, Group I with lacunar infarction and minor neurological deficits, and Group II with none. The total IIEF-5 scores were compared between the two groups and repeatedly evaluated six months after discharge.</p><p><b>RESULTS</b>According to the total scores of IIEF-5, the prevalence of ED in Group II (95%) was higher, and the incidence of severe ED was significantly increased (60.0% vs. 44.4%, P < 0.05) as compared with Group II. In both the two groups, severe ED was more often seen in diabetic patients. At six months after discharge, the total scores of IIEF-5 were significantly increased (11.2 +/- 3.2 vs. 15.6 +/- 2.2, P < 0.05).</p><p><b>CONCLUSION</b>ED is significantly increased in old males with lacunar infarction, and it is more severe in diabetic patients. Post-stroke rehabilitation care helps to improve ED.</p>
