White-Matter Hyperintensities and Lacunar Infarcts Are Associated with an Increased Risk of Alzheimer's Disease in the Elderly in China

BACKGROUND AND PURPOSE: This study investigated the contribution of white-matter hyperintensities (WMH) and lacunar infarcts (LI) to the risk of Alzheimer's disease (AD) in an elderly cohort in China. METHODS: Older adults who were initially cognitively normal were examined with MRI at baseline, and followed for 5 years. WMH were classified as mild, moderate, or severe, and LI were classified into a few LI (1 to 3) or many LI (≥4). Cognitive function was assessed using the Mini Mental State Examination and the Activities of Daily Living scale. RESULTS: Among the 2,626 subjects, 357 developed AD by the end of the 5-year follow-up period. After adjusting for age and other potential confounders, having only WMH, having only LI, and having both WMH and LI were associated with an increased risk of developing AD compared with having neither WMH nor LI. Moderate and severe WMH were associated with an increased risk of developing AD compared with no WMH. Furthermore, patients with many LI had an increased risk of developing AD compared with no LI. CONCLUSIONS: Having moderate or severe WMH and many LI were associated with an increased risk of developing AD, with this being particularly striking when both WMH and LI were present.

Influence of early intensively antihypertensive treatment on hematoma enlargement in patients with hypertensive cerebral hemorrhage / 重庆医学

Objective To investigate the effect of blood pressure control for early enlargement of hypertensive intracerebral hemorrhage.Methods A total of 96 patients were divided randomly into intensive blood pressure lowering group (n = 48 )and standard antihypertensive group(n=48).Patients were checked head CT and was evaluated defect of nerve function score immedi-ately when they arrive at hospital and after 24 hours.Then the clinical curative effect was evaluated.Results The defect of nerve function score in intensive blood pressure lowering group was lower than that of the standard antihypertensive group(P <0.05 ). The hematomas volume within 24 hours of admission and the rate of hematoma enlargement of intensive blood pressure lowering group were sharply smaller than those of standard antihypertensive group(P <0.05).Conclusion Controlling blood pressure ac-tively could decrease ratio early enlargement of hematoma and defect of nerve function score in patients with hypertensive cerebral hemorrhage.

Clinical analysis of nicergoline in treatment for 80 patients with chronic cerebral circulation insufficiency / 局解手术学杂志

Objective To observe the curative effect of nicergoline in the treatment of chronic cerebral circulation insufficiency ( CC-CI) . Methods 160 cases with CCCI were randomly divided into the treatment group which were administered 10 mg of oral Nicergoline, three times per day for one month,and the control group which were given 20 mg of oral nimodipine,three times per day for one month. The clinical effective rate and the transcranial Doppler ultrasound ( TCD) between the two groups before and after treatment were observed. Results There were significant difference in clinical effective rate and TCD index assessment between the two groups(P<0. 05). Conclu-sion Nicergoline is an effective and safe treatment for chronic cerebral circulation insufficiency.
