Abstract
BACKGROUND Midlife hypertension is a risk factor for cognitive decline in late-life but little is known about the impact of long-term hypertension on cognitive change over time. METHODS We examined blood pressure and cognitive function in 2777 participants (baseline: 2000-2003, 45-75 years, 48.4% men) from the Heinz Nixdorf Recall study. Blood pressure was assessed at three study visits and cognitive function was assessed at both follow-ups (mean follow-up: 5.1 years). Z-score differences in five neuropsychological tests, defining cognitive decline, were derived from linear regression models including age and education. The association of cognitive decline over 5 years and blood pressure over 10 years (classified as: normal blood pressure (>10 years, reference), prevalent hypertension (>10 years), incident hypertension t1 (>5 years), incident hypertension t2 (<5 years), temporary hypertension (at least one hypertensive reading)) was calculated using linear regression models resulting in coefficient b and 95% confidence interval. We calculated interactions with age (linear and with a cutoff at 65 years). RESULTS Participants with prevalent hypertension showed a greater cognitive decline in both verbal memory tests. Incident hypertension t1 was associated with a greater decline in the visuospatial organization test. There was no interaction with age. CONCLUSION This study showed that prevalent high blood pressure over 10 years is related to cognitive decline. Prevalent hypertension with longer exposure time may be more detrimental than temporary hypertension for cognitive function.

Abstract
BACKGROUND Our objective was to investigate the impact of both prevalent and incident hypertension on cognition in middle-aged individuals followed up for 10 years and to explore the extent to which blood pressure control by antihypertensive drugs could modify this relationship. METHOD Three thousand, two hundred and one participants from the Vieillissement Santé Travail (Aging, Health and Work) (VISAT) cohort study, aged 32, 42, 52 and 62 years at baseline were followed up 5 and 10 years later. Blood pressure, antihypertensive medication use as well as memory and speed cognitive performances were assessed at baseline and follow-up. Linear mixed models were used for analyses. RESULTS At 10-year follow-up, compared with nonhypertensive participants, prevalent hypertensive individuals showed poorer global cognitive performances (β = -2.99 ± 0.96, P = 0.002 for participants aged 32 or 42 years at baseline and β = -5.94 ± 1.00, P < 0.001 for those aged 52 or 62). Patients with incident hypertension had poorer global cognitive performances over time compared with patients without hypertension. When considering prevalent hypertension and blood pressure control status by antihypertensive therapy, untreated and uncontrolled hypertension were associated with poorer cognitive performances than controlled and no hypertension (untreated hypertension compared with no hypertension: β = -5.51 ± 0.75, P < 0.001; uncontrolled hypertension compared with no hypertension: β = -6.13 ± 1.40, P < 0.001). CONCLUSION Our findings showed that both prevalent and incident hypertension are associated with poorer global cognitive function in middle-aged individuals and suggested a potential preventive effect of antihypertensive therapy on cognition. Thus, for brain functioning, heightened efforts to detect hypertension and adequately treat it are of critical importance.

Abstract
Although hypertension is a prominent vascular risk factor for late-life cognitive decline, the underlying pathophysiological mechanism remains unclear. Accordingly, the aim of this study was to examine the role of white matter microstructural integrity in hypertension-related cognitive detriments. We recruited 66 cognitively normal older adults, comprising 41 hypertensive patients and 25 normotensive controls. All participants underwent a comprehensive neuropsychological battery. White matter microstructural integrity was assessed using a tract-based automatic analysis approach derived from diffusion spectrum imaging. Mediating effects of white matter integrity were evaluated using structural equation modeling analyses. The results revealed that hypertensive older adults displayed poorer processing speed, executive function, and memory encoding. Lower white matter microstructural integrity was observed in the hypertensive elderly patients, primarily in long-range association fiber bundles. In particular, low microstructural integrity in specific tract bundles connecting frontal and posterior cerebral regions was found to underlie the adverse relationships between hypertension and multiple cognitive domains, including processing speed, executive function, memory encoding, and memory retention. Our findings suggest that hypertension may impair multiple cognitive functions by undermining white matter microstructures, even in cognitively intact older adults, thus further highlighting the necessity of monitoring vascular health to prevent cognitive decline.

Abstract
BACKGROUND Previous studies suggest that heart failure (HF) is an independent risk factor for cognitive decline. A better understanding of the relationship between HF, cognitive status, and cognitive decline in a community-based sample may help clinicians understand disease risk. OBJECTIVE To examine whether persons with HF have a higher prevalence of cognitive impairment and whether persons developing HF have more rapid cognitive decline. DESIGN This observational cohort study of American adults in the Atherosclerosis Risk in Communities (ARIC) study has two components: cross-sectional analysis examining the association between prevalent HF and cognition using multinomial logistic regression, and change over time analysis detailing the association between incident HF and change in cognition over 15 years. PARTICIPANTS Among visit 5 (2011-2013) participants (median age 75 years), 6495 had neurocognitive information available for cross-sectional analysis. Change over time analysis examined the 5414 participants who had cognitive scores and no prevalent HF at visit 4 (1996-1998). MEASUREMENTS The primary outcome was cognitive status, classified as normal, mild cognitive impairment [MCI], and dementia on the basis of standardized cognitive tests (delayed word recall, word fluency, and digit symbol substitution). Cognitive change was examined over a 15-year period. Control variables included socio-demographic, vascular, and smoking/drinking measures. RESULTS At visit 5, participants with HF had a higher prevalence of dementia (adjusted relative risk ratio [RRR] = 1.60 [95% CI 1.13, 2.25]) and MCI (RRR = 1.36 [1.12, 1.64]) than those without HF. A decline in cognition between visits 4 and 5 was - 0.07 standard deviation units [- 0.13, - 0.01] greater among persons who developed HF compared to those who did not. Results did not differ by ejection fraction. CONCLUSION HF is associated with neurocognitive dysfunction and decline independent of other co-morbid conditions. Further study is needed to determine the underlying pathophysiology.

Abstract
OBJECTIVES To identify the access to health care services and associated factors in adults living in the city of Ribeirão Preto, São Paulo, Brazil, in 2007. METHODS A cross-sectional population-based epidemiological study with a sample developed in three stages. The variability introduced in the third sampling fraction was corrected by the attribution of weights, resulting in a sample of 2,471 participants. The outcome prevalence was estimated according to socio-demographic, behavioral and health-related variables. In order to identify associated factors, the regression of Poisson was used, obtaining crude and adjusted prevalence ratios. All estimates were calculated taking into account the effect of the sampling design. RESULTS The outcome prevalence increased according to the age, being higher in female individuals. A different set of variables remained in the final models, considering each gender separately. Among men, the monthly income > R$ 1,400.00; scores > 823.6 to the Economic Indicator of Ribeirão Preto (IERP) and daily average of sitting down time (154.4 - 240 min/day) constituted themselves into protective factors, whereas the increase of age and scholarship, hospitalization, diabetes and hypertension constituted risk factors for the use of the services. Among women, health self-reported as regular, hospitalization, diabetes and hypertension characterized factors positively associated to the outcome at matter. CONCLUSIONS The results indicate the need for planning actions aimed at capturing male individuals, as well as the revaluation of detection and control of diabetes and hypertension programs, aimed at the primary prevention of terminal cardiovascular events.

Abstract
RESUMO: Objetivos: Investigar a prevalência e os fatores associados à incapacidade funcional em idosos residentes em Ribeirão Preto, SP, em 2007. Métodos: Estudo transversal de base populacional, com amostra complexa selecionada em três estágios. Para correção do efeito de desenho amostral, utilizou-se amostra ponderada (nw) de 536 idosos. A dependência funcional para atividades da vida diária foi aferida mediante a utilização de questionário estruturado e validado para estudos epidemiológicos de base populacional. Prevalências brutas do desfecho e estratificadas segundo variáveis sociodemográficas, comportamentais, relacionadas à saúde e à morbidade referida foram calculadas por pontos e por intervalos com 95% de confiança. Razões de prevalências brutas e ajustadas foram estimadas por pontos e por intervalos, utilizando-se a regressão de Poisson. Resultados: A prevalência bruta de incapacidade foi 50,31%. Nos modelos multivariados, após ajustamento intragrupos (modelos finais), as seguintes variáveis permaneceram independentemente associadas ao desfecho: sociodemográficas (idade, escolaridade e contribuição com a renda familiar); comportamentais (média diária de tempo sentado); relacionadas à saúde (hipertensão, doença isquêmica do coração, uso de medicamentos e baixo desempenho cognitivo); morbidade referida (número de doenças referidas e baixa acuidade auditiva). Conclusão: A elevada prevalência de incapacidades em idosos de Ribeirão Preto, bem como a presença de associações entre variáveis potencialmente modificáveis e o desfecho, impõe a necessidade de medidas específicas de promoção e prevenção em saúde com vistas à melhora da qualidade de vida desse estrato populacional já bem representado nas últimas pirâmides populacionais do município.

Abstract
OBJECTIVE To know the prevalence and factors associated to low cognitive performance in a representative sample of the adult population in a society aging progressively. METHOD Cross-sectional population-based study carried out in a three-stage sampling: 81 census tracts (primary sampling unity) were randomly selected, followed by 1,672 households and 2,471 participants (weighted sample) corresponding to the second and third stages, respectively. The outcome prevalence was calculated according sociodemographic, behavioral and health related variables. Crude and adjusted prevalence ratios were estimated using Poisson regression. RESULTS The prevalence of low cognitive performance was high, mainly among females, and indicated linear trends into categories of age, schooling, income, plasma fibrinogen and self-reported health status. In multivariate models, gender, diabetes, fibrinogen and self-reported health status presented positive associations, while schooling, employment and sitting time presented negative associations with the outcome. CONCLUSION Interventions related to diabetes and fibrinogen levels control as well as improvement in health care might delay low cognitive performance in societies aging progressively as such the study population.

Abstract
This review describes the features of Alzheimer's disease and discusses the evidence that antihypertensive therapies may be beneficial in its treatment and prevention. Drugs acting via the renin-angiotensin system are considered and it is suggested that these drugs may produce their effects via mechanisms other than by their antihypertensive actions. Using evidence from animal studies, the role of angiotensin as a neurotransmitter and its involvement in the control of normal cognitive function is described. Studies of angiotensin and human cognition are reviewed along with studies investigating the possible link between disorders of the system, either inherited or acquired, and the symptoms of Alzheimer's disease. The therapeutic potential of screening for markers of renin-angiotensin abnormality for the prediction of Alzheimer's disease is considered, as is the potential use of agents known to influence the renin-angiotensin system in the treatment or prevention of the disease.

Abstract
Hypertension has adverse effects on cognition, can alter cerebral vasculature integrity, and is associated with the pathogenesis of dementia. Using meta-analysis, we correlated blood pressure to multiple cognitive domains among older adults free of clinical stroke and dementia. We identified 230 studies indexed in PubMed and PsycINFO relating blood pressure and cognition. After applying exclusion criteria, we selected n = 12 articles with n = 4,076 participants (age range 43-91 years). Meta-analysis yielded an association between blood pressure and episodic memory (r = -.18, p < .001) and between blood pressure and global cognition (r = -.07, p < .001). When limiting analyses to studies adjusting for vascular covariates (n = 8, n = 2,141), blood pressure was modestly related to global cognition (r = -.11, p < .001), attention (r = .14, p = .002), and episodic memory (r = -.20, p < .001) with a trend for language (r = -.22, p = .07). Findings underscore the need to manage blood pressure as a key prevention method in minimizing abnormal cognitive aging prior to the onset of clinical dementia.

Abstract
PURPOSE OF REVIEW Clinically apparent and subclinical forms of vascular disease including stroke are important causes of cognitive dysfunction. In this review, we will describe the current nomenclature for vascular cognitive impairment (VCI) from the histopathological and clinical perspectives to raise awareness among practitioners about the interaction between conventional and novel vascular risk factors and VCI, with an emphasis on the prevention and risk factor modification. RECENT FINDINGS There is substantial evidence from observational studies and clinical trials that conventional risk factors such as hypertension, diabetes, dyslipidemia, smoking, and atrial fibrillation play a role in the development of VCI. Additional novel risk factors such as the metabolic syndrome have been associated with cognitive dysfunction as well. Targeting these risk factors will minimize the burden of VCI in our aging population. SUMMARY The concept of VCI has evolved to describe a continuum of cognitive disorders in which vascular brain injury plays a role, ranging from mild cognitive impairment to dementia. Future research is needed to clarify the role of risk factor modification in limiting vascular brain injury to prevent VCI and progression to dementia.

Abstract
Secondary data analyses examined the differences in cognitive and instrumental activities of daily living (IADL) performance among hypertensive individuals taking one of four classes of antihypertensive medications, hypertensive individuals not taking any antihypertensive medications, and normotensive individuals (N=770). After adjusting for covariates, significant group differences were evident on all measures (speed of processing, motor speed, reaction time, ps < .05) except memory and Timed IADL (ps > .05). Follow-up a priori planned comparisons compared hypertensive individuals not on medications to each of the four antihypertensive medication groups. Results indicated that only those on beta blockers (BB) were significantly slower in speed of processing (ps < .05). A priori planned comparisons also revealed that normotensive individuals had better cognitive performance on measures of processing speed, motor speed, and reaction time than hypertensive individuals regardless of antihypertensive medication use. Additionally, normotensive individuals performed significantly better on memory (Digit and Spatial Span) than individuals with hypertension on medications. No differences were found between groups on memory (Hopkins Verbal Learning Test) or Timed IADL performance. With regard to antihypertensive medications, the use of BBs was associated with slowed processing speed. These analyses provide empirical evidence that hypertension primarily impacts speed of processing, but not severe enough to affect IADL performance. Given the contribution of processing speed to memory and executive function performance, this is an important finding. Clinicians need to take into consideration the potential negative impact that BBs may have on cognition when determining the best treatment of hypertension among older adult patients.

Abstract
OBJECTIVES To assess the impact of hypertension and diabetes mellitus on sentence comprehension in older adults. METHOD Two hundred and ninety-five adults aged 55 to 84 (52% men) participated in this study. Self-report mail survey combined with medical evaluations were used to determine eligibility. Multiple sources were used to determine whether hypertension and diabetes were present or absent and controlled or uncontrolled. Sentence comprehension was evaluated with two tasks: embedded sentences (ES) and sentences with multiple negatives (MN). Outcome measures were percent accuracy and mean reaction time of correct responses on each task. RESULTS Regression models adjusted for age, gender, and education showed that the presence of hypertension impaired comprehension on the multiple negatives task (p < .01), whereas the presence of diabetes impaired the comprehension of embedded sentences (p < .05). Uncontrolled diabetes significantly impaired accurate comprehension of sentences with multiple negatives (p < .05). No significant patterns were found for reaction time. DISCUSSION The presence of hypertension and diabetes adversely affected sentence comprehension, but the relative contribution of each was different. These findings support the researchers' earlier speculations on the neurobiological mechanisms underlying the effects of hypertension and diabetes on language and cognition in aging. Uncontrolled disease status demonstrated more complicated age-related effects on sentence processing, highlighting the clinical importance for cognitive aging of identifying and managing vascular risk factors.

Abstract
OBJECTIVES Blood pressure is an indicator of vascular health that has been associated with cognition and quality of life in older age. Few studies have examined blood pressure across everyday cognitive tasks, which may have superior predictive functional utility than traditional cognitive measures. We explored blood pressure as a predictor of everyday problem solving (EPS) performance in middle-aged and older women. METHOD Community-dwelling women (age: 51-91) with low-normal blood pressure to mild hypertension underwent traditional and everyday cognitive testing. EPS was determined by the number of safe/effective solutions generated for real-world scenarios. RESULTS Analyses revealed that lower systolic blood pressure and pulse pressure were associated with worse EPS ability after controlling for age, education, and traditional cognitive abilities. DISCUSSION These results support that blood pressure may be an important predictor of everyday cognitive abilities in older age. Potential implications for real-world functioning are discussed.

Abstract
OBJECTIVES In this article, we discuss the importance of studying the relationship between health and cognitive function, and some of the methods with which this relationship has been studied. METHODS We consider the challenges involved, in particular operationalization of the health construct and causal inference in the context of observational data. We contrast the approaches taken, and review the questions addressed: whether health and cognition are associated, whether changes in health are associated with changes in cognition, and the degree of interdependency among their respective trajectories. RESULTS A variety of approaches for understanding the association between cognition and health in aging individuals have been used. Much of the literature on cognitive change and health has relied on methods that are based at least in part on the reorganization of between-person differences (e.g., cross-lag analysis) rather than relying more fully on analysis of within-person change and joint analysis of individual differences in within-person change in cognition and health. DISCUSSION We make the case for focusing on the interdependency between within-person changes in health and cognition and suggest methods that would support this.

Abstract
Previous research has established that the effects of chronically increased blood pressure (BP) on cognition interact with adult age, but the relevant cognitive processes are not well defined. In this cross-sectional study, using a sample matched for age, years of education, and sex, 134 individuals with either normal BP (n = 71) or chronically high BP (n = 63) were categorized into younger (19-39 years), middle-aged (41-58 years), and older (60-79 years) groups. Using a between-subjects analysis of variance (ANOVA), covarying for race and years of education, composite measures of executive function and perceptual speed both exhibited age-related decline. The executive function measure, however, was associated with a differential decline in high BP older adults. This result held even when the executive function scores were covaried for speed, demonstrating an independent, age-related effect of higher BP on executive function.

Abstract
OBJECTIVES To evaluate effects of health status on word-finding difficulty in aging, adjusting for the known contributors of education, sex, and ethnicity. DESIGN Cross-sectional. SETTING Community. PARTICIPANTS Two hundred eighty-four adults aged 55 to 85 (48.6% female) participating in an ongoing longitudinal study of language in aging. MEASUREMENTS Medical, neurological, and laboratory evaluations to determine health status and presence or absence of hypertension and diabetes mellitus. Lexical retrieval evaluated with the Boston Naming Test (BNT) and Action Naming Test. RESULTS Unadjusted regression models showed that presence of diabetes mellitus was not related to naming. Presence of hypertension was associated with significantly lower accuracy on both tasks (P<.02). Adjustment for demographics attenuated the effect of hypertension (P<.08). For the BNT, a variable combining presence, treatment, and control of hypertension was marginally significant (P<.10), with subjects with uncontrolled hypertension being least accurate (91.4%). Previously observed findings regarding the effects of age, education, sex, and ethnicity were confirmed. CONCLUSION In this sample of older adults, hypertension contributed to the word-finding difficulty of normal aging, but diabetes mellitus did not.

Abstract
BACKGROUND Individuals at greater risk for cardiovascular disease (CVD) display poorer cognitive functioning across various cognitive domains. This finding is particularly prevalent among older adults; however, few studies examine these relationships among younger adults or among African Americans. PURPOSE The objective was to examine the relationships among 2 cardiovascular risk factors, elevated blood pressure and elevated triglycerides, and verbal learning in a community-based sample of African Americans. METHODS Measurements of blood pressure and triglycerides were obtained in 121 African-American adults and compared to performance on 3 domains of the California Verbal Learning Test-II (CVLT-II). RESULTS Blood pressure was not related to CVLT-II performance. Triglyceride levels were inversely related to CVLT-II performance. Higher triglyceride levels were associated with poorer immediate, short delay and long delay recall. CONCLUSIONS Consistent with studies involving older participants, the current investigation shows that in a nonelderly sample of African Americans, triglyceride levels may be related to cognitive functioning. Because early detection and intervention of vascular-related cognitive impairment may have a salutary effect, future studies should include younger adults to highlight the impact of cardiovascular risk on cognition.

Abstract
Cardiovascular disease and stroke disproportionately affect the elderly. The risk for stroke and transient ischemic attack increases exponentially with age. Blood pressure is a potent modifiable target for reducing the risk for stroke in the elderly. In elderly patients with isolated systolic hypertension and those with intracranial atherosclerotic disease, blood pressure lowering has consistently been shown to be well tolerated and effective in reducing the risk for stroke and its complications. Evidence suggests that ambulatory blood pressure monitoring may provide a more sensitive means of detecting patients at risk and monitoring therapeutic effect. Agents that modify the renin-angiotensin system, particularly angiotensin receptor blockers, may confer additional benefit in stroke protection beyond blood pressure lowering. Several clinical trials currently in progress promise to provide guidance regarding the optimal choice of agent and degree of blood pressure lowering for prevention of stroke and cognitive decline in elderly patients.

Abstract
While dementia affects 6-10% of persons 65 years or older, industrialized countries have witnessed an alarming rise in obesity. However, obesity's influence on dementia remains poorly understood. We conducted a systematic review and meta-analysis. PUBMED search (1995-2007) resulted in 10 relevant prospective cohort studies of older adults (40-80 years at baseline) with end points being dementia and predictors including adiposity measures, such as body mass index (BMI) and waist circumference (WC). There was a significant U-shaped association between BMI and dementia (P = 0.034), with dementia risk increased for obesity and underweight. Pooled odds ratios (OR) and 95% confidence intervals (CI) for underweight, overweight and obesity compared with normal weight in relation to incident dementia were: 1.36 (1.07, 1.73), 0.88 (0.60, 1.27) and 1.42 (0.93, 2.18) respectively. Pooled ORs and 95% CI for obesity and incident Alzheimer's disease (AD) and vascular dementia were 1.80 (1.00, 3.29) vs. 1.73 (0.47, 6.31) and were stronger in studies with long follow-up (>10 years) and young baseline age (<60 years). Weight gain and high WC or skin-fold thickness increased risks of dementia in all included studies. The meta-analysis shows a moderate association between obesity and the risks for dementia and AD. Future studies are needed to understand optimal weight and biological mechanisms.

Abstract
OBJECTIVE Recent research indicates that n-3 fatty acids can inhibit cognitive decline, perhaps differentially by hypertensive status. DESIGN We tested these hypotheses in a prospective cohort study (the Atherosclerosis Risk in Communities). Dietary assessment using a food-frequency questionnaire and plasma fatty acid exposure by gas chromatography were completed in 1987-1989 (visit 1), while cognitive assessment with three screening tools--the Delayed Word Recall Test, the Digit Symbol Substitution Test of the Wechsler Adult Intelligence Scale-Revised and the Word Fluency Test (WFT)--was completed in 1990-1992 (visit 2) and 1996-1998 (visit 4). Regression calibration and simulation extrapolation were used to control for measurement error in dietary exposures. SETTING Four US communities--Forsyth County (North Carolina), Jackson (Mississippi), suburbs of Minneapolis (Minnesota) and Washington County (Maryland). SUBJECTS Men and women aged 50-65 years at visit 1 with complete dietary data (n = 7814); white men and women in same age group in the Minnesota field centre with complete plasma fatty acid data (n = 2251). RESULTS Findings indicated that an increase of one standard deviation in dietary long-chain n-3 fatty acids (% of energy intake) and balancing long-chain n-3/n-6 decreased the risk of 6-year cognitive decline in verbal fluency with an odds ratio (95% confidence interval) of 0.79 (0.66-0.95) and 0.81 (0.68-0.96), respectively, among hypertensives. An interaction with hypertensive status was found for dietary long-chain n-3 fatty acids (g day-1) and WFT decline (likelihood ratio test, P = 0.06). This exposure in plasma cholesteryl esters was also protective against WFT decline, particularly among hypertensives (OR = 0.51, P < 0.05). CONCLUSION One implication from our study is that diets rich in fatty acids of marine origin should be considered for middle-aged hypertensive subjects. To this end, randomised clinical trials are needed.

Abstract
The longitudinal association between the rate of change in blood pressure and cognitive decline was examined in an area probability sample from a population-based survey of elderly Mexican Americans, 65 years of age or older obtained in 1993--1994, 1995--1996, 1998--1999, and 2000--2001 (n = 2859). The sample was divided into two groups at baseline: hypertensives had a systolic blood pressure (SBP) > or = 140 mm Hg, a diastolic blood pressure (DBP) > or = 90 mm Hg, or indicated a prior diagnosis of hypertension, and the normotensive group. Cognition was indexed by the Mini-Mental State Examination (MMSE). Neither SBP nor DBP at baseline predicted cognitive decline. However, the mean slope for SBP in the normotensive group showed an increase of 4.55mm Hg (increase from Time 1 to Time 2 was 123mm Hg to 132 mm Hg) and was significant in a regression model predicting cognitive decline even after adjusting for covariates. These findings suggest an association between increasing SBP and cognitive decline for normotensive elderly in this study population.

Abstract
The authors examined the influence of age and hypertensive status (normotensive, controlled, untreated, or uncontrolled) on several cognitive tests via multiple regression in 357 nondemented, community-dwelling older men (mean age=67 years) whose hypertensive status was stable over 3 years and who had no medical comorbidities. Age was negatively associated with performance on all but 1 test. Age interacted with hypertensive status on verbal fluency and word list immediate recall; older uncontrolled hypertensives exhibited significantly larger age decrements on these tests compared with normotensives. These findings suggest that uncontrolled hypertension produces specific cognitive deficits beyond those attributable to age alone. These and previous findings illustrate that health conditions such as hypertension should be regularly considered in studies of "normal" cognitive aging.

Abstract
The aim of this study was to compare the effects of telmisartan/hydrochlorothiazide (HCTZ) vs lisinopril/HCTZ combination on ambulatory blood pressure and cognitive function in elderly hypertensive patients. A total of 160 patients, 76 men and 84 women, aged 61-75 years, with sitting diastolic blood pressure (DBP)>90 mmHg and <110 mmHg and systolic blood pressure (SBP)>140 mmHg were randomized to receive temisartan 80 mg/HCTZ 12.5 mg o.d. or lisinopril 20 mg/HCTZ 12.5 mg o.d. for 24 weeks, according to a prospective, open-label, blinded end point, parallel-group design. At the end of a 2-week wash-out period and after 12 and 24 weeks of active treatment, 24-h noninvasive ambulatory BP monitoring (ABPM) was performed and cognitive function was evaluated through six different tests (verbal fluency, Boston naming test, word-list memory, word-list recall, word-list recognition and Trails B). Both treatments significantly reduced ambulatory BP. However, the telmisartan/HCTZ combination produced a greater reduction in 24-h, day-time and night time ABPM values. Lisinopril/HCTZ did not induce significant changes in any of the cognitive function test scores at any time of the study, whereas at both 12 and 24 weeks telmisartan/HCTZ significantly improved the word-list memory score (+17.1 and +15.7%, respectively, P<0.05 vs baseline), the word-list recall score (+13.5 and +16.9%, P<0.05) and the Trails B score (-33 and -30.5%, P<0.05). These results suggest that in elderly hypertensive patients treatment with telmisartan/HCTZ produces a slightly greater reduction in ambulatory BP than lisinopril/HCTZ combination and, unlike this latter, improves some of the components of cognitive function, particularly episodic memory and visuospatial abilities.

Abstract
BACKGROUND Hypertension is associated with diminished performance on tests of cognitive function. The degree to which those diagnosed with hypertension have controlled blood pressure (BP) levels may be a critical determinant of cognitive outcomes. Persons with hypertension and poorly controlled BP are likely to display the worst performance on cognitive tests. PURPOSE The purpose is to examine potential interactive relations of hypertension diagnostic status and current BP levels to cognitive function. METHODS Participants were 101 healthy older adults (ages 53-84, 62% male, 90% White, 29% diagnosed with hypertension) who engaged in biomedical and neuropsychological assessment. RESULTS After statistical adjustment for age and education, persons with high BP performed more poorly than those with normal BP on the Visual Reproductions-Immediate and Delayed Recall and the Grooved Pegboard tests. Diagnosed hypertension was related to poorer performance on the Grooved Pegboard tests. An interaction of diagnosed hypertension and BP level revealed that those diagnosed with hypertension and also having poorly controlled BP levels performed least well on the Grooved Pegboard tests and the Trail Making Test-Part A. CONCLUSION Irrespective of prior diagnostic status, individuals with high BP displayed compromised performance on tests of nonverbal memory, motor speed, and manual dexterity. However, as compared to the other groups, those diagnosed with hypertension and also having poorly controlled BP elevation were most vulnerable to difficulties on tests of perceptuo-motor speed, motor speed, and manual dexterity. These findings suggest the need for increased attention to preventative efforts with respect to BP assessment and control in older adults to help preserve cognitive function.

Abstract
O presente estudo delineou o perfil de saúde de uma população idosa, residente em São Carlos, São Paulo, Brasil, no ano de 2003. A população do estudo (n = 523) foi constituída pelo universo de pessoas com sessenta anos e mais, cadastradas no Programa Saúde da Família e no Cartão Nacional de Saúde. A prevalência de incapacidades, doenças crônicas e estado cognitivo foi estimada por ponto e por intervalos, construídos com 95% de confiança. Os resultados do estudo mostraram um predomínio de mulheres com baixa escolaridade; 24,8% referiram não receber aposentadoria ou pensão; 43,6% relataram não participar de atividades de integração social; 46,7% necessitavam de ajuda para realizar de uma a três atividades da vida diária. Com relação à morbidade, 74,9% eram portadores de 1 a 5 doenças crônicas não transmissíveis e 56,2% alcançaram escores abaixo de 24 no teste cognitivo, 87% procuraram por serviços de saúde e 22,4% necessitaram de algum tipo de internação. Conclui-se pela necessidade de maior adequação dos profissionais e serviços de saúde para uma efetiva implementação de políticas públicas de atenção adequada aos idosos.

Abstract
OBJECTIVE This prospective, randomised, open-label, blinded-endpoint study was to compare the effects of the angiotensin II (Ang II) AT1 receptor antagonist valsartan with those of the ACE inhibitor enalapril on blood pressure (BP) and cognitive functions in elderly hypertensive patients. METHODS One hundred and forty-four patients aged 61-80 years with mild to moderate essential hypertension (DBP > or =95 mmHg and < or =110 mmHg at the end of a 2-week placebo run-in period) were randomly assigned to once daily (o.d.) treatment with valsartan 160 mg ( n=73) or enalapril 20 mg ( n=71) for 16 weeks. The patients were examined every 4 weeks during the study, with pre-dose BP (standard mercury sphygmomanometer, Korotkoff I and V) and heart rate (pulse palpation) being recorded at each visit. Cognitive function was evaluated at the end of the wash-out period and after 16 weeks of active treatment by means of five tests (verbal fluency, the Boston naming test, word list memory, word list recall and word list recognition). RESULTS Both valsartan and enalapril had a clear antihypertensive effect, but the former led to a slightly greater reduction in SBP/DBP at 16 weeks (18.6+/-4.6/13.7+/-4.0 mmHg vs 15.6+/-5.1/10.9+/-3.9 mmHg; P<0.01). Enalapril did not induce any significant changes in any of the cognitive function test scores; valsartan significantly increased the word list memory score (+11.8%; P<0.05 vs baseline and P<0.01 vs enalapril) and the word list recall score (+18.7%; P<0.05 vs baseline and P<0.01 vs enalapril), but not those of the other tests. CONCLUSION These findings indicate that, in elderly hypertensive patients, 16 weeks of treatment with valsartan 160 mg o.d. is more effective than enalapril 20 mg o.d. in reducing BP, and (unlike enalapril) improves some of the components of cognitive function, particularly episodic memory.
