And Function

Throughout the lifespan, common variations in systemic health and illness contribute to alterations in vasculature structure and function throughout the body, significantly increasing risk for cardiovascular and cerebrovascular disease (CVD). CVD is a prevalent cause of mortality in late life; it also promotes brain alterations, contributing to cognitive decline and, when severe, vascular dementia. Even prior to diseased states, individual variation in CVD risk is associated with structural and functional brain alterations. Yet, how cumulative asymptomatic alterations in vessel structure and function contribute to more subtle changes in brain tissue integrity and function that emerge in late life is unclear. Finally, vascular risk factors are associated with the clinical progression of neurodegenerative diseases such as Alzheimer’s disease (AD); however, recent theory posits that vascular degeneration may serve a contributory role in these conditions. This chapter reviews how lifespan changes in vascular health contribute to degenerative changes in neural tissue and the subsequent development of cognitive impairment and/or vascular dementia. It first discusses associations between vascular risk factors and cognition and also how declining vascular health may lead to cognitive impairment and dementia. Next, it identifies basic aspects of cerebrovascular anatomy and physiology sustaining tissue health and discusses how vulnerabilities of this system contribute to neurodegenerative changes. Finally, it reviews evidence of vascular contributions to AD and presents ideas for future research to better understand the full spectrum of cerebrovascular contributions to brain aging, cognitive decline, and dementia.

Background: Recent nationally representative studies of stroke patients have revealed that vascular risk factors are not as aggressively controlled in women compared to men. Medically underserved minority populations are at particularly high risk for poor control of vascular risk factors; however, little is known about sex differences in this population. Methods: Sex-specific vascular risk factors and admission medications were assessed for 440 consecutive ischemic stroke patients (39% female) admitted to a safety-net public hospital in Los Angeles County. Multivariate logistic regression was used to determine sex differences in vascular risk factors, adjusting for age and race. Results: The mean age was 58.9 (SE 10.6) years, 58% were Hispanic, 7% were white, 13% were black, 20% were Asian, and 1% were Native American. Stroke classification (using modified TOAST) revealed the following distribution: 35% small vessel, 20% large vessel, 7% cardioembolic, 23% cryptogenic, 13% >1 possible etiology, and 3% other mechanisms (e.g. drug use). Women had higher mean glycosylated hemoglobin levels than men (8.0% vs 7.4%, p<0.01) and were more likely than men to have a history of type 2 diabetes (49% vs. 40% male, p=0.04), systolic blood pressure > 140 mm Hg (72% vs. 62%, p=0.03), total cholesterol > 200 mg/dL (46% vs. 36%, p=0.04), and low HDL levels (<40 mg/dL for men and <50 mg/dL for women)(83% vs. 79%, p <0.01). Men were more likely than women to have a previous history of stroke (19% vs. 13%, p = 0.05), smoking (49% vs 19%, p<0.01), and alcohol abuse (28% vs. 7%, p<0.01). After adjustment for race and age, women were more likely than men to have total cholesterol > 200 mg/dL (OR 1.56, 95% CI 1.05-2.31), BMI ≥ 30 kg/m 2 (OR 1.55, 95% CI 1.03-2.34), systolic blood pressure >140 mm Hg (OR 1.46, 95% CI 0.96-2.22), low HDL (1.26, 95% CI 0.76-2.08), and triglyceride level > 150 mg/dL (OR 1.09, 95% CI 0.74-1.63); however, the latter 3 were not significant. After adjustment for race and age, men were more likely than women to have a history of smoking (OR 4.54, 95% CI 2.78-7.14) and alcohol abuse (OR 5.56, 95% CI 2.86-11.11). Conclusions: In this multi-ethnic population with inadequate access to care, women are more likely than men to have obesity, hypertension, and dyslipidemia while men are more likely than women to smoke or abuse alcohol. Larger studies are necessary to validate these findings. In the meantime, interventions aimed at reducing the incidence of metabolic syndrome components among women and smoking and alcohol abuse among men in underserved communities are likely warranted.

Objective and Design: We conducted a multinational observational study on features of consecutive acute ischemic stroke (AIS), intracranial hemorrhage (ICH), and cerebral venous or sinus thrombosis (CVST) among SARS-CoV-2 infected patients. Main Outcome Measures: We investigated the association of demographics, clinical data, geographical regions, and countries’ health expenditure among AIS patients with the risk of large vessel occlusion (LVO), stroke severity as measured by National Institute of Health stroke scale (NIHSS), and stroke subtype as measured by the TOAST criteria. Additionally, we applied unsupervised machine learning algorithms to uncover possible similarities among stroke patients. Results: Among the 136 tertiary centers of 32 countries who participated in this study, 71 centers from 17 countries had at least one eligible stroke patient. Out of 432 patients included, 323(74.8%) had AIS, 91(21.1%) ICH, and 18(4.2%) CVST. Among 23 patients with subarachnoid hemorrhage, 16(69.5%) had no evidence of aneurysm. A total of 183(42.4%) patients were women, 104(24.1%) patients were younger than 55 years, and 105(24.4%) patients had no identifiable vascular risk factors. Among 380 patients who had known interval onset of the SARS-CoV-2 and stroke, 144(37.8%) presented to the hospital with chief complaints of stroke-related symptoms, with asymptomatic or undiagnosed SARS-CoV-2 infection. Among AIS patients 44.5% had LVO; 10% had small artery occlusion according to the TOAST criteria. We observed a lower median NIHSS (8[3-17], versus 11[5-17]; p=0.02) and higher rate of mechanical thrombectomy (12.4% versus 2%; p<0.001) in countries with middle to high-health expenditure when compared to countries with lower health expenditure. The unsupervised machine learning identified 4 subgroups, with a relatively large group with no or limited comorbidities. Conclusions and Relevance: We observed a relatively high number of young, and asymptomatic SARS-CoV-2 infections among stroke patients. Traditional vascular risk factors were absent among a relatively large cohort of patients. The stroke severity was lower and rate of mechanical thrombectomy was higher among countries with middle to high-health expenditure.

Management Protocol

Dementia prevention is highly important. Improved control of vascular risk factors has the potential to decrease dementia risk, but may be difficult. Therefore, we developed and piloted a care management protocol for Veterans at risk for dementia. We enrolled 32 Veterans with diabetes and hypertension, at least one of which was poorly controlled, and cognitive impairment. Participants were randomly assigned to a 6-month care management intervention or to usual care. At enrollment, 6-months and 12-months, we assessed cognitive performance, mood, and diabetes and hypertension control. At follow-up, diastolic blood pressure was lower in intervention participants at 6 months (p=.041) and 12 months (p=.022); hemoglobin A1c, global mental status and mood did not differ between groups. Recall of a distractor list (p=.006) and logical memory long-delay recall (p=.036) were better at 6 months in the intervention group (p=.006). Care management may contribute to improved control of dementia risk factors.

Main Effect

Background: Several vascular risk factors, including hypertension, diabetes, body mass index, and smoking status are found to be associated with cognitive decline and the risk of Alzheimer's disease (AD). We aimed to investigate whether an aggregation of vascular risk factors modulates the amplitude of low-frequency fluctuation (ALFF) in patients with mild cognitive impairment (MCI).Methods: Forty-three MCI patients and twenty-nine healthy controls (HCs) underwent resting-state functional MRI scans, and spontaneous brain activity was measured by the ALFF technique. The vascular risk profile was represented with the Framingham Heart Study general cardiovascular disease (FHS-CVD) risk score, and each group was further divided into high and low risk subgroups. Two-way ANOVA was performed to explore the main effects of diagnosis and vascular risk and their interaction on ALFF.Results: The main effect of diagnosis on ALFF was found in left middle temporal gyrus (LMTG) and left superior parietal gyrus (LSPG), and the main effect of risk on ALFF was detected in left fusiform gyrus (LFFG), left precuneus (LPCUN), and left cerebellum posterior lobe (LCPL). Patients with MCI exhibited increased ALFF in the LMTG and LSPG than HCs, and participants with high vascular risk showed increased ALFF in the LFFG and LCPL, while decreased ALFF in the LPCUN. An interaction between diagnosis (MCI vs. HC) and FHS-CVD risk (high vs. low) regarding ALFF was observed in the left hippocampus (LHIP). HCs with high vascular risk showed significantly increased ALFF in the LHIP than those with low vascular risk, while MCI patients with high vascular risk showed decreased ALFF in the LHIP than HCs with high vascular risk. Interestingly, the mean ALFF of LHIP positively correlated with word recall test in HCs with high vascular risk (rho = 0.630, P = 0.016), while negatively correlated with the same test in MCI patients with high vascular risk (rho = −0.607, P = 0.001).Conclusions: This study provides preliminary evidence highlighting that the aggregation of vascular risk factors modulates the spontaneous brain activity in MCI patients, and this may serve as a potential imaging mechanism underlying vascular contribution to AD.
