Background: Hypertension is associated with poorer cognitive functions, but the mechanisms are unclear.Objective: This research aims to explore the cognitive status of elderly patients with hypertension and the possible mechanisms of hypertension affecting cognitive function.Methods: Data were obtained from the China Longitudinal Aging Study (CLAS), and a total of 128 residents, aged 60 years and above, were recruited in this study. Based on whether they had hypertension, these 128 people were divided into the hypertension (n = 64) and non-hypertension groups (n = 64). The Beijing version of the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were used to assess the overall cognitive function of the subjects, while digit span, language fluency, Wechsler mapping, and Wechsler wood block were used to assess their domain-specific cognitive function (both at baseline and follow-up stages). At the same time, we also examined baseline blood biochemical indicators (such as total protein, fasting plasma glucose (FPG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), cholesterol, and triglyceride) and baseline MRI data of hippocampus and amygdala volume and temporal polar cortex thickness.Results: The total protein and thickness of temporal polar cortex in patients with hypertension were significantly higher than those in normal controls, but the scores on MMSE, MoCA, digit span, Wechsler mapping and Wechsler wood block at baseline were significantly lower than those in normal controls (p < 0.05). By linear regression analysis and correlation analysis (age and education were controlled), we found that baseline Wechsler mapping scores were negatively correlated with total protein (B = −0.243, t = −3,735, p < 0.001, 95% confidence interval (CI): −0.371 to −0.114); and both the follow-up MMSE score (B = 2.657, t = 2.002, p = 0.049, 95% CI: 0.009~5.306) and the change score of MMSE (r = −0.025, p = 0.047) were related to the thickness of the right temporal pole cortex. Then, by linear regression analysis (mediating model), we found that hypertension may influence follow-up MMSE scores by influencing the cortical thickness of the right temporal pole (B = 1.727, p = 0.022, 95% CI: 0.261–3.193).Conclusions: Elderly patients with hypertension exhibit poorer overall cognitive function and executive function, and the mechanism may be related to the effect of hypertension on the cortical thickness of the right temporal pole.

BackgroundCausal relationships between vascular factors and late-life depression are controversial.AimsTo investigate prospective associations between risk factors for vascular disease and incidence of late-life depression.MethodOf 661 community participants aged 65 years or over, without depression at baseline, 521 (79%) were re-evaluated 2 years later. At baseline and follow-up, a diagnostic interview for depression was carried out and information on vascular status, disability and cognitive function was gathered.ResultsPre-existing heart disease, incident stroke and lower baseline high-density lipoprotein cholesterol level were significantly associated with incidence of late-life depression, independently of disability and cognitive function.ConclusionsThese results provide some support for a vascular aetiology of late-life depression. However, important risk factors for cerebrovascular disease such as hypertension and diabetes were not implicated, and the associations with lipid levels might still be explained by affective states earlier in life.

Whether HDL is associated with dementia risk is unclear. In addition to apoA1, other apolipoproteins are found in HDL, creating subspecies of HDL that may have distinct metabolic properties. We measured apoA1, apoC3, and apoJ levels in plasma and apoA1 levels in HDL that contains or lacks apoE, apoJ, or apoC3 using a modified sandwich ELISA in a case-cohort study nested within the Ginkgo Evaluation of Memory Study. We included 995 randomly selected participants and 521 participants who developed dementia during a mean of 5.1 years of follow-up. The level of total apoA1 was not significantly related to dementia risk, regardless of the coexistence of apoC3, apoJ, or apoE. Higher levels of total plasma apoC3 were associated with better cognitive function at baseline (difference in Modified Mini-Mental State Examination scores tertile 3 vs. tertile 1: 0.60; 95% CI: 0.23, 0.98) and a lower dementia risk (adjusted hazard ratio tertile 3 vs. tertile 1: 0.73; 95% CI: 0.55, 0.96). Plasma concentrations of apoA1 in HDL and its apolipoprotein-defined subspecies were not associated with cognitive function at baseline or with the risk of dementia during follow-up. Similar studies in other populations are required to better understand the association between apoC3 and Alzheimer’s disease pathology.

We sought to analyse the long-term follow-up after primary repair of tetralogy of Fallot in infancy in the first year of life, paying particular attention to growth of the pulmonary arteries and the need for reintervention. We performed a combined retro- and prospective echocardiographic study, including measurements of the pulmonary valve and right and left pulmonary arteries, indexed to the square root of body surface area, in 62 patients prior to primary repair, 18 to 24 months after this event, and at the most recent follow-up, with a mean of 80.4 ± 24 months. Of these, 38 patients, with an age at operation of 5.0 ± 3.4 months, had presented preoperatively with hypoxic spells or increasing cyanosis. The remaining 24 patients had been asymptomatic, with adequate flow of blood to the lungs. Their age at elective operation was 7.4 ± 3.0 months. A transannular patch was needed in 37 patients (63%). There were 3 early postoperative deaths (4.8%).Cross-sectional echocardiography revealed a significantly smaller diameter for the pulmonary valve in patients who had been symptomatic preoperatively compared to the asymptomatic patients (1.09 versus 1.3 cm/BSA0.5; p = 0.019). The diameters of the right and left pulmonary arteries did not differ significantly between the groups. Examination of echocardiographic data obtained 18 to 24 months postoperatively in 43 patients revealed a significant increase in the diameter of the pulmonary arteries; 0.83 ± 0.17 cm/BSA0.5 versus 1.1 ± 0.26 cm/BSA0.5 for the diameter of the right pulmonary artery, 0.85 ± 0.2 cm/BSA0.5 versus 1.0 ± 0.25 cm/BSA0.5 for the left pulmonary artery. On comparison between individuals, 18.6% and 25.6% of the patients, respectively, did not show any change in the diameters of their right and left pulmonary arteries, whereas the increase in diameter reached or exceeded the measurements in normal controls in 55.8% and 46.5% of the patients, respectively. On recent follow-up, with a range from 56 to 147 months, no further increase in the indexed diameters of the pulmonaries could be documented in 21 of 33 patients. Of these, 9.1% and 18.2%, respectively, presented with small right and left pulmonary arteries compared with measurements obtained in normal controls. Moderate pulmonary incompetence was found on colour flow mapping in one-third. Of 56 longterm survivors, 8 (14%) had required reinterventions, which were surgical in 6 and achieved by transcatheter techniques in the other 2 patients. Thus, primary correction of tetralogy of Fallot in infancy, with restoration of normal pressures and flows, resulted in sustained increase in the diameters of the right and left pulmonary arteries. It allowed for early normal development of the proximal pulmonary arterial system in most patients regardless of their age and symptomatic status at operation. Patients with persistent subnormal diameter of the pulmonary arteries did not present with significantly elevated right ventricular pressure. Early one-stage repair of tetralogy of Fallot in infancy was associated with a low rate of reinterventions.

AbstractObesity is a critical issue in patients with schizophrenia, which is considered to be brought about by both environmental and genetic factors. Apolipoprotein E (APOE) gene polymorphisms might be involved in the pathogenesis of schizophrenia, however, the effect of APOE gene polymorphism on obesity has never been investigated in Chinese aging with schizophrenia. This cross-sectional study was to investigate the effect of obesity on cognitive and psychiatric symptoms in elderly participants with schizophrenia. At the same time, we also discussed the inner link between APOE E4 and obesity. 301 elderly participants with schizophrenia and 156 normal controls were included in the study. Their cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), psychiatric symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS), and APOE gene polymorphism was determined by polymerase chain reaction (PCR). The prevalence of obesity in elderly schizophrenic patients and healthy controls accounted for 15.9% (48/301) and 10.3% (16/156), respectively, with no statistically significant difference. By using stepwise linear regression analysis, we found that elevated fasting blood glucose, hypertension, and hyperlipidemia were risk factors for obesity in elderly schizophrenic patients. Although there was no direct correlation between APOE E4 and obesity in patients with schizophrenia, it was significantly correlated with hyperlipemia(r = − 0.154, p = 0.008), suggesting that APOE E4 may induce obesity in elderly patients with schizophrenia through hyperlipemia, However, the above conclusions do not apply to the normal elderly. What’s more, we did not find a link between obesity and cognitive function or mental symptoms for both patients with schizophrenia and normal controls. APOE E4 is associated with hyperlipidemia in elderly schizophrenic patients, which may be a risk factor for obesity, however, the above conclusion does not apply to the normal elderly.

ABSTRACTBackground: Gamma glutamyltransferase (GGT) plays a role in cellular glutathione uptake, which is an important element of antioxidant mechanisms. An increase in serum GGT is thought to be an early and sensitive marker of oxidative stress. Oxidative stress has a role in the pathogenesis of Alzheimer's disease (AD). The aim of this study was to investigate the GGT levels in AD.Method: In this cross-sectional study, 132 patients with AD (mean age: 74.1 ± 7.4, female 62.9%) and 158 age- and gender-matched normal controls (mean age: 74.5 ± 6.3, female 67.1%) were evaluated. For cognitive assessment, MMSE and clock drawing tests were performed; DSM-IV and NINCDS-ADRDA criteria were used. Serum GGT, aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase concentrations were determined.Results: Median (min-max) GGT levels were 18 (9–70) in AD group and 17 (5–32) in normal controls. Mann-Whitney U test showed that GGT levels were significantly higher in AD patients (p = 0.012). Linear regression analysis revealed AD was an independent correlate of elevated GGT levels. Hypertension, diabetes mellitus, total cholesterol, and low density lipoprotein cholesterol were not associated with GGT levels.Conclusion: GGT levels were increased significantly in AD patients. To evaluate the role of GGT as a marker of oxidative stress in AD, further studies are needed.

<b><i>Introduction:</i></b> The prevalence of cognitive impairment in patients undergoing hemodialysis (HD) is higher than that in healthy controls. To date, studies on the association between cognitive function and cerebral oxygenation in these patients are limited. Therefore, in this study, we aimed to cross-sectionally investigate the association between cognitive assessment scores and clinical factors, including cerebral oxygenation, in patients undergoing HD. <b><i>Methods:</i></b> In this observational study, 193 HD patients were included. Cerebral regional oxygen saturation (rSO<sub>2</sub>) was monitored using an INVOS 5,100c oxygen saturation monitor. Poor cognition was defined as a Mini-Mental State Examination (MMSE) score ≤23. We analyzed the association between MMSE score and clinical factors, including cerebral rSO<sub>2</sub>. <b><i>Results:</i></b> MMSE score in HD patients included in this study was 26.8 ± 3.3. There were 164 patients (85%) with MMSE score ≥24 and 29 patients (15%) with an MMSE score ≤23. In the patients with MMSE score ≥24, cerebral rSO<sub>2</sub> (53.8% ± 8.3%) was significantly higher than that in patients with MMSE score ≤23 (49.5% ± 9.8%; <i>p</i> = 0.013). Multivariable linear regression analysis was performed using the following confounding factors: age, mean blood pressure, cerebral rSO<sub>2</sub>, HD duration, ultrafiltration rate, hemoglobin, serum Cr, serum calcium, serum phosphate, total cholesterol, high-density lipoprotein cholesterol levels, serum albumin, presence of diabetes mellitus or chronic glomerulonephritis, history of comorbid cardiovascular or cerebrovascular disease, and use of renin-angiotensin-aldosterone system inhibitors or vitamin D analogs. MMSE score was independently and significantly associated with age (standardized coefficient: −0.244) and cerebral rSO<sub>2</sub> (standardized coefficient: 0.180). <b><i>Conclusions:</i></b> MMSE score was independently associated with age (negative effect) and cerebral rSO<sub>2</sub> (positive effect) in this cross-sectional study. Further prospective studies are needed to clarify whether maintaining cerebral oxygenation prevents the deterioration of cognitive function in patients undergoing HD.

Abstract Based on the 2018 American Academy of Neurology guideline, the prevalence of mild cognitive impairment (CI) increases from 6.7% at 60-64 years to 25.2% at 80-84 years. There is interest to identify potential biomarkers in the retina for CI and dementia. The aims of this analysis was to test whether hypertensive retinopathy (HR) was associated with cognitive function using data from the Study of Women’s Health Across the Nation (SWAN), Michigan cohort. SWAN, launched in 1996/97, is a longitudinal study of women traversing midlife and into late adulthood. Starting in 2000, cognitive function tests were administered: East Boston Memory Test immediate (EBMTi) and 10-minute delay (EBMTd) for verbal episodic memory; digit span backwards (DSB) for working memory; and symbol digits modalities test (SDMT) for perception speed, motor speed, and visual scanning. Z-scores were calculated for EBMTi, EBMTd, DSB and SDMT and averaged at follow-up visit 15 (2015/16). Eye exams were performed on 255 women (66 + 2.6 years) at follow-up visit 16 (2016/17). HR was based on presence/absence of arteriovenous nicking. Logistic regression showed a statistically significant association of lower average cognitive Z-score with HR (p-value 0.03, beta=-0.21 [95% confidence interval: -0.40 to -0.02]) adjusting for measured hypertension or anti-hypertensive drugs, years of measured hypertension, race, education, and age. Preliminary results indicate that HR is associated with lower cognitive test scores in women in their 60s-70s. This association between a simple ophthalmic exam finding of systemic hypertension, i.e., arteriovenous nicking, and lower cognitive function is consistent with a cerebrovascular mechanism of CI.

There is evidence that social relationships may modify cognitive decline in older people. We examined the prospective association between social support and cognitive function among community-dwelling older people. Japanese adults recruited at health checkups in suburban towns were surveyed at baseline and one-year follow-up. Cognitive function was assessed using the Montreal Cognitive Assessment, Japanese version (MoCA-J). Social support from coresiding family, non-coresiding family, and neighbors/friends was assessed using self-administered questionnaires. Multivariable linear regression analysis was conducted to examine the effects of social support on MoCA-J scores at follow-up. Data were analyzed from 121 older people (mean age (standard deviation): 73.86 (4.95) years). There was a positive association between social support exchanges with neighbors and friends and MoCA-J scores at follow-up after covariate adjustment (unstandardized β = 1.23, p = 0.006). Social support exchanges with coresiding family and non-coresiding family and relatives were not associated with MoCA-J scores at follow-up (coresiding family: Unstandardized β = 0.28, p = 0.813, non-coresiding family and relatives: Unstandardized β = 0.51, p = 0.238). The provision of emotional support to neighbors and friends had the largest effect on MoCA-J scores. Our findings suggest that social support exchanges with neighbors and friends are protective against cognitive decline.

Abstract Among 2,038 older Chinese adults in the U.S., we examined the relationship between physical function (Short Performance Physical Battery [SPPB], [instrumental] activities of daily living [ADL/IADL] limitations) at baseline (2011-2013) and changes in cognitive function in the two-year follow-up (2013-2015). Cognitive function was measured by the East Boston Memory Test (EBMT), the Digit Span Backwards assessment (DSB), the Symbol Digit Modalities Test (SDMT), and the Mini-Mental State Examination (MMSE). During the two-year follow-up, 41.8%-50.88% of the participants decreased in cognitive function and 32.88%-44.8% increased. In linear regression that adjusted for baseline cognitive function, education, age, and other covariates, baseline SPPB and ADL/IADL limitations were significantly associated with changes in cognitive function in the two-year follow-up (SPPB: βEBMT=0.0149, p&lt;0.05; βDSB=0.0253, p&gt;0.05; βSDMT=0.2742, p&lt;0.01; βMMSE=0.1070, p&lt;0.001; ADL/IADL limitations: βEBMT= -0.0401, p&lt;0.0001; βDSB= -0.0410, p&lt;0.05; βSDMT= -0.3027, p&lt;0.01; βMMSE= -0.2566, p&lt;0.0001). This suggests that better physical function predicts positive changes in cognitive function.

Object Pre- and postoperative cognitive function were evaluated in 25 patients with Parkinson's disease (PD) who underwent unilateral posteroventral pallidotomy (PVP) to clarify the effects of this operation on cognitive function. Methods Cognitive function was assessed before surgery and 1 month and 3 months afterward by using a battery of neuropsychological tests consisting of orientation, digit span (forward and backward), digit learning, 5-minute memory of five words, similarities, serial sevens, animal name listing, and the kana pick-out test, as well as the Japanese version of the Mini-Mental State. Preoperative evaluation revealed that patients experienced difficulties in performing the neuropsychological tasks of reasoning and abstraction, working memory of numerals, word fluency, and concept formation compared with 36 healthy volunteers (p < 0.05). A simple regression analysis showed strong relationships in a negative fashion between preoperative (r = 0.81, p = 0.002) and 1-month (r = 0.79, p = 0.0059) and 3-month (r = 0.85, p = 0.0016) postoperative gross-total scores and Hoehn and Yahr staging. Preoperative and postoperative scores at 1 month and 3 months were analyzed by analysis of variance, but only the Fisher's post hoc test revealed the source of difference. All tasks except orientation (p = 0.0292) were unchanged in the 10 patients who underwent surgery on the right side. The scores for this task at 1 month postsurgery were significantly lower (p = 0.0203) but improved to preoperative values by 3 months. In the 15 patients who underwent surgery on the left side significant differences among tasks were revealed for serial sevens (p = 0.0471) and animal naming (p = 0.0425). The scores for these tasks were significantly lower at 1 month postoperatively (p = 0.0431 for serial sevens and p = 0.0408 for animal naming), but improved by 3 months after the operation. Conclusions The present data revealed that cognitive dysfunction in patients with PD relates to advancement of Hoehn and Yahr stage, but PVP is not associated with significant long-lasting cognitive deficits.
