Abstract
Hypertension is prevalent among postmenopausal women worldwide and is a risk factor for cognitive impairment. This study examined the cognitive differences between Taiwanese postmenopausal women with and without hypertension after natural menopause and identified factors associated with cognitive function in hypertensive postmenopausal women. A two-group comparative design study of 171 Taiwanese postmenopausal participants (mean age = 64.8±6.6) was conducted in southern Taiwan. Cognitive performance on neuropsychological tests was evaluated, and demographic, health, menopausal, and disease related variables were assessed. Compared to the non-hypertensive group, women with hypertension showed significantly worse performance and a higher percentage of impairment in global cognitive functioning and memory. Fewer years of education and longer duration of hypertension were associated with lower global cognitive function, and increased age was associated with lower scores in delayed memory. Cognitive screening as well as training on global cognitive functioning and memory are needed for postmenopausal hypertensive women. (148 words).

Abstract
INTRODUCTION Cognitive functions play a crucial role in daily functioning. Unfortunately, some cognitive abilities decline in the process of healthy aging. An increasing body of evidence has highlighted the role of lifestyle habits and cardiovascular diseases, such as high blood pressure, in increasing the risk of cognitive decline. Surprisingly, although hypertension is a modifiable risk factor for cerebrovascular damage, the role of hypertension on cognitive impairment development is not still clear. Several key questions remain unresolved, and there are many inconsistent results in studies considering this topic. This review is aimed to systematically analyze the results found by the studies that investigated whether high blood pressure, in both hypertensive and healthy people, is related to cognitive performance. Furthermore, it points to evaluate the role of age in this relationship. Method: The review process was conducted according to the PRISMA statement. Restrictions were made, selecting the studies in English and published in peer-review journals, including at least one cognitive measure and blood pressure measurement. Studies that included participants with medical conditions, dementia, psychiatric disorders, strokes, and brain injury were excluded. Cross-sectional and longitudinal studies were analyzed separately. Finally, blood pressure measured at young life (18-39 years), midlife (age 40-64 years), elderly (65-74 years), and old age (≥75 years) were considered. Results: The review allows 68 studies to be selected, which include 154,935 participants. The results provided evidence of an adverse effect of exposure to high blood pressure on cognitive performance. High blood pressure in midlife was linked with poorer cognitive functioning; this evidence was found in cross-sectional and longitudinal studies. However, this association declines with increasing age and tends to become inconsistent. In older people, the relationship between blood pressure and cognitive performance is non-linear, highlighting a beneficial effect of high blood pressure on cognition. Conclusions: Despite some limitations, this review showed that cardiovascular and neuro-cognitive systems do not operate in isolation, but they are related. Blood pressure can be considered an early biomarker of cognitive impairment, and the necessity of early blood pressure measurement and control was underlined.

Abstract
Background: High blood pressure has been associated with an increased risk of developing cognitive impairment. However, this relationship is unclear. This study aims to systematically review the effects of blood pressure on executive functioning, language, memory, attention and processing speed. Methods: The review process was conducted according to the PRISMA-Statement, using the PubMed, PsycINFO, PsycARTICLES and MEDLINE databases. Restrictions were made by selecting studies, which included one or more cognitive measures and reported blood pressure recordings. Studies that included participants with medical conditions or people diagnosed with dementia, psychiatric disorders, stroke and head trauma were excluded. The review allows selecting fifty studies that included 107,405 participants. The results were reported considering different cognitive domains separately: global cognitive functioning, attention, processing speed, executive functions, memory and visuospatial abilities. Results: Higher blood pressure appears to influence cognitive performance in different domains in the absence of dementia and severe cardiovascular diseases, such as strokes. This relationship seems to be independent of demographic factors (gender and education), medical co-morbidity (diabetes), and psychiatric disorders (depression). Furthermore, it presents different patterns considering ageing. In the elderly, a sort of “cardiovascular paradox” is highlighted, which allows considering higher blood pressure as a protective factor for cognitive functioning. Conclusions: The results underline that higher blood pressure is associated with a higher risk of cognitive decline in people without dementia or stroke. These findings highlight the need to introduce early management of blood pressure, even in the absence of clinical hypertension, to prevent the risk of a decline of cognitive functioning typically associated with ageing.

Abstract
PURPOSE Hypertension trials often exclude patients with complex health problems and lack generalizability. We aimed to determine if systolic blood pressure (SBP) in patients undergoing antihypertensive treatment is associated with 1-year changes in cognitive/daily functioning or quality of life (QoL) in persons aged ≥75 years with or without complex health problems. METHODS We analyzed data from a population-based prospective cohort study (Integrated Systematic Care for Older Persons [ISCOPE]) with a 1-year follow-up. Stratified by SBP level in the year before baseline, we used mixed-effects linear regression models to evaluate the change from baseline to 1-year follow-up in outcome measures (Mini-Mental State Examination [MMSE], Groningen Activity Restriction Scale [GARS], and EQ-5D-3L). We adjusted for age, sex, and baseline MMSE/GARS/EQ-5D-3L scores and stratified for complex health problems as a proxy for frailty. RESULTS Participant (n = 1,266) age averaged 82.4 (SD 5) years, and 874 (69%) were women. For participants undergoing antihypertensive therapy (1,057; 83.5%) and with SBP <130 mm Hg, crude cognitive decline was 0.90 points MMSE, whereas in those with SBP >150 mm Hg, it was 0.14 points MMSE (ie, 0.76-point less decline; P for trend = .013). Complex health problems modified the association of SBP with cognition; the association was seen in those with antihypertensive treatment (P for trend <.001), not in those without (P for trend = .13). Daily functioning/QoL did not differ across the strata of SBP or antihypertensive treatment. CONCLUSIONS Participants aged ≥75 years undergoing antihypertensive treatment, with SBP ≥130 mm Hg compared to <130 mm Hg, showed less cognitive decline after 1 year, without loss of daily functioning or QoL. This effect was strongest in participants with complex health problems. More studies should be conducted to determine if there is a causal relation and to understand the mechanism of the association observed.

Medication adherence in renal transplant recipients: A latent variable model of psychosocial and neurocognitive predictors. PLoS One 2018; 13:e0204219.

Abstract
Objective Estimates indicate that 20–70% of renal transplant recipients are medication non-adherent, significantly increasing the risk of organ rejection. Medication adherence is negatively impacted by lower everyday problem solving ability, and associations between depressive symptoms, self-efficacy, and adherence are reported in renal transplant recipients. Nonetheless, to date, these associations have not been examined concurrently. Given the relationship between non-adherence and organ rejection, it is critical to gain a better understanding of the predictors of adherence in renal transplant recipients. To this end, we modeled relationships among cognitive abilities, depressive symptoms, self-efficacy, and adherence in this group. Methods Participants (N = 211) underwent renal transplant at least one year prior to participation. Adherence was measured via self-report, medication possession ratio, and immunosuppressant blood-level. Traditionally-measured neurocognitive and everyday problem-solving abilities were assessed. Depressive symptoms were measured via self-report, as were general and medication adherence related self-efficacy. Structural equation modeling was used to assess the fit of the model to available data. Results Everyday problem solving and self-efficacy had direct positive associations with adherence. Depressive symptoms were negatively associated with self-efficacy, but not adherence. Traditionally-measured neurocognitive abilities were positively associated with self-efficacy, and negatively associated with depressive symptoms. Conclusions We present a comprehensive investigation of relationships between cognitive and psychosocial factors and adherence in medically stable renal transplant recipients. Findings confirm the importance of everyday problem solving and self-efficacy in predicting adherence and suggest that influences of depressive symptoms and neurocognitive abilities are indirect. Findings have important implications for future development of interventions to improve medication adherence in renal transplant recipients.

Abstract
BACKGROUND the appropriateness of lowering systolic blood pressure remains controversial in the oldest-old. We tested whether systolic blood pressure is associated with all-cause mortality and change in cognitive function for patients prescribed antihypertensive treatment and those without treatment. METHODS we studied participants in the population-based Leiden 85-plus cohort study. Baseline systolic blood pressure and use of antihypertensive treatment were predictors; all-cause mortality and change in cognitive function measured using the Mini-Mental State Examination were the outcomes. Grip strength was measured as a proxy for physical frailty. We used Cox proportional hazards and mixed-effects linear regression models to analyse the relationship between systolic blood pressure and both time to death and change in cognitive function. In sensitivity analyses, we excluded deaths within 1 year and restricted analyses to participants without a history of cardiovascular disease. RESULTS of 570 participants, 249 (44%) were prescribed antihypertensive therapy. All-cause mortality was higher in participants with lower blood pressure prescribed antihypertensive treatment (HR 1.29 per 10 mmHg lower systolic blood pressure, 95% CI 1.15-1.46, P < 0.001). Participants taking antihypertensives showed an association between accelerated cognitive decline and lower blood pressure (annual mean change -0.35 points per 10 mmHg lower systolic blood pressure, 95% CI -0.60, -0.11, P = 0.004); decline in cognition was more rapid in those with lower hand grip strength. In participants not prescribed antihypertensive treatment, no significant associations were seen between blood pressure and either mortality or cognitive decline. CONCLUSIONS lower systolic blood pressure in the oldest-old taking antihypertensives was associated with higher mortality and faster decline in cognitive function.

Abstract
BACKGROUND Hypertension guidelines recommend home blood pressure (HBP) monitoring in adjunct to office blood pressure (OBP) for its greater reproducibility and prognostic utility in the prevention of cardiovascular outcomes, especially stroke. To date, the relationship between HBP and cognitive function remains unexplored. METHODS We examined HBP as a cognitive predictor in a multi-ethnic group of community-dwelling adults aged 60 and over (N = 133) using neuropsychological measures and analyzed the data using multiple regression analyses. We also employed "everyday cognition" measures that have been found to have higher prognostic utility for real-world functioning than traditional cognitive tasks. RESULTS Good to perfect HBP monitoring compliance over seven days was achieved by 88.7% of the participants with superior reliability (ICC≥.96) to office readings. Higher home systolic BP and pulse pressure predicted worse processing speed, executive function, and everyday cognitive function, whereas lower home diastolic BP predicted worse everyday cognition. Office readings were similarly associated with everyday cognitive function but with no other cognitive measures. CONCLUSION Our findings are the first to validate HBP as a predictor of neuropsychological function in older adults beyond cognitive screening. Differential relationships among blood pressure variables and specific cognitive domains were observed. With proper standardization and training, we demonstrated that HBP can be obtained in a multi-ethnic community-dwelling older adult cohort. Our findings emphasize the importance of employing blood pressure and cognitive measures that are adequately sensitive to detect vascular-related cognitive impairment in a relatively healthy population. Implications regarding proper HBP measurement for hypertension management, cognitive health, and everyday function are discussed.

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
Chronic degenerative conditions are very common in the elderly. According to medical literature, there is a correlation between cognitive impairment among elders and arterial hypertension/hyperglycemia which in turn are common diseases among the elderly population worldwide. Nonetheless, data on the association between cognitive impairment and Metabolic Syndrome (MetS) remains controversial. OBJECTIVE To compare the cognitive status of Brazilian elderly outpatients with and without MetS. METHODS A cross-sectional case-control study with 49 subjects (25 MetS and 24 controls) who underwent a global geriatric and neuropsychological assessment was carried out. The scores for cognitive abilities (sustained attention, alternating attention, immediate memory, working memory, memory - immediate recall, memory - delayed recall, memory - recognition, executive function, ideomotor praxis, constructive praxis, naming ability, verbal fluency) were compared with the data for the normal population and differences between case and control groups were analyzed using Student's t-test or the Mann-Whitney test. RESULTS Forty-five patients (91.8%) were female, with a mean age of 73.9±5.9 years, and 3.0±1.0 years of schooling. A significant difference (p<0.01) was found between case and control groups regarding the MetS components. For cognitive abilities, no statistically significant difference was detected between the groups and all subjects presented low cognitive scores. CONCLUSION The results obtained in the present study showed that MetS was not associated with cognitive impairment in this population. Further prospective studies are necessary to investigate the influence of well-controlled MetS on cognitive performance among elders.

Abstract
Despite the widespread assumption that cognitive decline is an inherent part of the normal aging process, research suggests that part of the variance in age-related cognitive decline is attributable to modifiable factors common in geriatric populations such as cerebrovascular risk factors. We completed a literature search using Science Citation Index and evaluated the most cited articles from the last 10 years to determine the extent to which investigations of normal aging and cognition account for the influence of cerebrovascular risk factors. We found that the majority of the most frequently cited literature does not adequately account for the contribution of cerebrovascular risk factors and therefore, it is possible that many conclusions about normal aging and cognition are flawed or incomplete. Further investigation of the role of cerebrovascular risk factors in age-related cognitive decline is imperative to more accurately understand the effect of aging on cognition.
