Background: Dementia is one of the major causes of dependency after stroke. The prevalence of poststroke dementia (PSD)defined as any dementia occurring after stroke is likely to increase in the future.Objectives: This study have two purposes: 1) Clinical study of MCI and dementia after the first stroke of patients with age of 60 years and older; 2) Overview on clinical characteristics of memory disorders. Subjects and method: 30 patients with were diagnosed with the first ischemic stroke in Huu nghi hospital together with the same number in the control group were involved in this study. The subjects in the two groups were all satisfied with included/excluded criteria diagnosis. Clinical diagnosis of new - onset dementia or other mental disorders was determined using neuropsychological tests. Results: Many functions of the brain were impaired including: logical memory, visiospatial skills, executive function were statistically reduced in the research group compared to the control. However, language function was also impacted but not as much as others. The frequency of the poststrocke dementia in this study was 12.3% while the poststrocke mild cognitive impairment rate was 47%. Conclusions: Global cognitive functioning together with memory state was significantly declined in the ischemic stroke compared to the control group.

OBJECTIVE: To investigate the clinical features and implication of restless legs syndrome (RLS) in ischemic stroke patients. METHODS: A total of 199 ischemic stroke patients were enrolled and assessed by polysomnography (PSG). RLS was identified according to criteria of International Restless Legs Syndrome Study Group. Epworth Sleepiness Scale (ESS), Mini-mental State Examination (MMSE) and Patient Health Questionnaire (PHQ-9) were used to evaluate the sleep quality, cognitive function and post-stroke depression, respectively. The National Institute of Health Stroke Scale (NIHSS) was used to evaluate the neurological function 3 months after stroke onset. Gender-and age-matched non-ischemic stroke patients with RLS (primary PLS) were selected as controls. RESULTS: Twenty-two cases of RLS were identified among 199 ischemic stroke patients (11.1%). Generalized linear model and logistic regression showed that low serum ferritin level (=-133.3 mg/L, 95%:-200.4--0.1, <0.01), subcortical infarction (=4.05, 95%:1.15-14.18, <0.05) and female (=2.54, 95%:1.04-6.23, <0.05) were identified as the risk factors of RLS in ischemic stroke patients. Compared with ischemic stroke patients without RLS, ESS increased by 4.37 (95%:2.33-6.41, <0.01), PHQ-9 increased by 2.17 (95%:0.39--3.94, <0.05), and reduced NIHSS from the baseline deceased by 0.97 (95%:-1.79--0.15, <0.05) in ischemic stroke patients with RLS. In addition, the incidence of moderate-severe depression increased (=4.27, 95%:1.40-13.10, <0.05) in ischemic stroke patients with RLS. The index of periodic leg movements of sleep (PLMS) with arousal in ischemic stroke patients with RLS was significantly higher than that in patients with primary RLS (=12.85, 95%:2.04-23.67, <0.05). CONCLUSIONS RLS is common in ischemic stroke patients and has adverse influences on patients.

Cerebral small vessel disease (CSVD) is a senile brain lesion caused by the abnormal structure and function of arterioles, venules and capillaries in the aging brain. The etiology of CSVD is complex, and disease is often asymptomatic in its early stages. However, as CSVD develops, brain disorders may occur, such as stroke, cognitive dysfunction, dyskinesia and mood disorders, and heart, kidney, eye and systemic disorders. As the population continues to age, the burden of CSVD is increasing. Moreover, there is an urgent need for better screening methods and diagnostic markers for CSVD, in addition to preventive and asymptomatic- and mild-stage treatments. Integrative medicine (IM), which combines the holistic concepts and syndrome differentiations of Chinese medicine with modern medical perspectives, has unique advantages for the prevention and treatment of CSVD. In this review, we summarize the biological markers, ultrasound and imaging features, disease-related genes and risk factors relevant to CSVD diagnosis and screening. Furthermore, we discuss IM-based CSVD prevention and treatment strategies to stimulate further research in this field.

OBJECTIVEThere is growing evidence indicating that reactions of inflammatory system play an important role in stroke and development of carotid plaques. It is purposed to understand the relationship between serum level of c-reactive protein (CPR) and size of cerebral infarction, carotid plaques and prognosis of ischemic stroke.

METHODSA total of 121 patients with ischemic stroke were included in the study. Serum level of CRP was measured within 72 hours after onset of index stroke. All patients were scored by CNDF based on deficit in their clinical neurological function, and examined with CT/MRI and carotid duplex ultrasound scanning.

RESULTSLeukocyte count and blood glucose level at admission were significantly higher in the group with abnormal serum level of CRP than those with normal one (P = 0.045 and P = 0.021, respectively). Incidence of territory infarction (42 cases, 61.76%) was also significantly higher than that of lacunar infarction (23 cases, 43.4%), with P = 0.044. Occurrence of carotid plaques was higher in the former (32 cases, 65.30%) than that in the latter (17 cases, 34.69%), with P = 0.035. CNFD scores were higher in the former (ranging 6 - 35, with a median of 18) than those in the latter (ranging 6 - 28, with a median of 11), with Mann-Whitney U test, P = 0.0001. And, more severe prognosis was also found in the former than in the latter, with P = 0.0001.

CONCLUSIONSerum level of CRP was an important prognostic marker for carotid plaque and stroke.

BACKGROUNDThe risk of clinical deterioration still exists in the acute phase despite the fact that patients with minor stroke may display less severe symptoms. The impact of this clinical deterioration on long-term outcomes is unknown. We characterized the clinical features of neurological deterioration (ND) in the acute phase of minor ischemic stroke (MIS) and investigated its impact on mid- and long-term outcomes.

METHODSThis was a multi-centered, prospective clinical study involving patients with MIS (the National Institutes of Health Stroke Scale, NIHSS ≤3) recruited from the China National Stroke Registry. Patients were included who had been hospitalized within 24 hours of stroke onset. Baseline characteristics, complication rates during hospitalization, etiology of stroke, as well as 3-, 6-, and 12-month post-stroke outcomes were compared between patients with and without ND during the acute phase.

RESULTSA number of 368 (15.2%) out of 2424 patients included in the study exhibited ND in the acute phase. Compared to patients without ND, patients with ND had longer hospital stay, increased rate of baseline diabetes, and multiple complications. Multivariate Logistic regression indicated that ND in acute phase was an independent factor predictive of increased dependence (adjusted odds ratio = 5.20, 95% CI, 3.51-7.70, P < 0.001) at 12-month post-stroke.

CONCLUSIONSThe risk of ND in the acute phase is high in patients with MIS. ND in the acute phase is an independent predictor for poor outcomes at 12 months post-stroke onset.

Lambl's excrescences are filiform structures attached to the edges of cardiac valves and have been associated with stroke. Here we report two patients with Lambl's excrescences who developed migraine-like headaches followed by cerebral infarction. Their Lambl's excrescences were first identified by transesophageal echocardiography. One patient was given aspirin and another had surgery for debridement of excrescences. Their outcomes were good. The migraine-like headache might be the first symptom of cerebral ischemia and might be triggered by micro-emboli originated from Lambl's excrescences. Patients with Lambl's excrescences should be closely monitored and surgery should be considered in recurrent stroke cases.

Stroke classified into ischemic and hemorrhagic subtypes, is among the most devastating diseases for human being. Certain drugs could increase the blood viscosity, thereby increasing the potential risk of ischemia. Anti-platelet and anti-coagulation drugs, as the treatment of first choice, increase the risk of intracranial hemorrhage and death. Here, we are the first to propose the concept of drug-related stroke, and discuss the treatment strategy for patients who are complicated with intracranial hemorrhage or plan to receive neurosurgical operation during either anti-platelet or anti-coagulation medication. We hope to arouse the attention for drug related stroke among the clinicians and offer recommendation for clinical intervention.

Periodontal disease is a potential predictor of stroke and cognitive impairment. However, this association is unclear in adults aged 50 yr and above without a history of stroke or dementia. We evaluated the association between the number of teeth lost, indicating periodontal disease, and cognitive impairment in community-dwelling adults without any history of dementia or stroke. Dental examinations were performed on 438 adults older than 50 yr (315 females, mean age 63+/-7.8 yr; 123 males, mean age 61.5+/-8.5 yr) between January 2009 and December 2010. In the unadjusted analysis, odds ratios (OR) of cognitive impairment based on MMSE score were 2.46 (95% CI, 1.38-4.39) and 2.7 (95% CI, 1.57-4.64) for subjects who had lost 6-10 teeth and those who had lost more than 10 teeth, respectively, when compared with subjects who had lost 0-5 teeth. After adjusting for age, education level, hypertension, diabetes, hyperlipidemia, and smoking, the relationship remained significant (OR, 2.0; 95% CI, 1.08-3.69, P=0.027 for those with 6-10 teeth lost; OR, 2.26; 95% CI, 1.27-4.02, P=0.006 for those with more than 10 teeth lost). The number of teeth lost is correlated with cognitive impairment among community-dwelling adults aged 50 and above without any medical history of stroke or dementia.

PURPOSE: Leptomeningeal collateral, in moyamoya disease (MMD), appears as an ivy sign on fluid-attenuated inversion-recovery (FLAIR) images. There has been little investigation into the relationship between presentation of ivy signs and old brain lesions. We aimed to evaluate clinical significance of ivy signs and whether they correlate with old brain lesions and the severity of clinical symptoms in patients with MMD. MATERIALS AND METHODS: FLAIR images of 83 patients were reviewed. Each cerebral hemisphere was divided into 4 regions and each region was scored based on the prominence of the ivy sign. Total ivy score (TIS) was defined as the sum of the scores from the eight regions and dominant hemispheric ivy sign (DHI) was determined by comparing the ivy scores from each hemisphere. According to the degree of ischemic symptoms, patients were classified into four subgroups: 1) nonspecific symptoms without motor weakness, 2) single transient ischemic attack (TIA), 3) recurrent TIA, or 4) complete stroke. RESULTS: TIS was significantly different as follows: 4.86+/-2.55 in patients with nonspecific symptoms, 5.89+/-3.10 in patients with single TIA, 9.60+/-3.98 in patients with recurrent TIA and 8.37+/-3.39 in patients with complete stroke (p=0.003). TIS associated with old lesions was significantly higher than those not associated with old lesions (9.35+/-4.22 vs. 7.49+/-3.37, p=0.032). We found a significant correlation between DHI and motor symptoms (p=0.001). CONCLUSION: Because TIS has a strong tendency with severity of ischemic motor symptom and the presence of old lesions, the ivy sign may be useful in predicting severity of disease progression.
