Presence Of Cognitive Decline Research Articles

Association between Hearing Aid Use and Cognitive Function in Persons with Hearing Impairment Stratified by Cardiovascular Risk.

The purpose of this study was to conduct a cross-sectional analysis of the association between hearing aid use and cognitive decline in community-dwelling older adults with hearing impairment, stratified by cardiovascular risk level. This cross-sectional study covers 1857 hearing-impaired individuals selected among 10,674 community-dwelling older adults (≥65 years of age) in Japan. We investigate the association between hearing aid use and cognitive decline stratified by cardiovascular risk level, by assessing self-reported hearing impairment and hearing aid use, absolute cardiovascular risk, cognitive function, and potential confounding factors. The association between hearing impairment severity and increased cardiovascular risk, and the benefit of hearing aid use in preventing cognitive decline, were examined in a binomial logistic regression analysis, with the presence of cognitive decline as the objective variable. In the low cardiovascular risk group, hearing aid users had a lower odds ratio for decline in executive function than non-users (odds ratio = 0.61, 95% confidence interval: 0.39-0.98). However, there was no significant association between hearing aid use and cognitive decline in the high cardiovascular risk group (p > 0.05). Among older adults with hearing impairment, hearing aid use was associated with the maintenance of executive function in individuals of low cardiovascular risk.

Neuroinflammation in Obese Children.

Obesity is associated with chronic persistent inflammation due to a pool of tissue macrophages that can penetrate the blood-brain barrier and cause neuroinflammation. The analysis of the association of CD14+CD163+ monocytes in the peripheral blood with cognitive functions in 56 obese children (mean age 11.95 (9.45; 14.45) years) was carried out. The control group consisted of 10 children (mean age 10.4 (9.3; 13.8) years). Standard deviation of the body mass index (SDS BMI) and height (SDS height) were calculated using WHO AnthroPlus software (for children of 6-19 years). Body composition was assessed using bioimpedance measurement. Mononuclear cells were isolated from whole blood by centrifugation on a Ficoll-Urografin density gradient (ρ=1.077 g/ml). The content of CD14+CD163+ monocytes in the peripheral blood was assessed by flow cytometry. To analyze cognitive functions, the intelligence coefficient (IQ) was calculated and a Russian adaptation of the Rey test was performed. We found an increase in the number of M2-polarized CD14+CD163+ monocytes in the peripheral blood with an increase in the obesity degree and in the presence of cognitive decline, as well as a negative correlation of the level of M2-polarized monocytes and IQ, taking into account the excess of visceral fat. The revealed data on the relationship of M2-polarized CD14+CD163+ peripheral blood monocytes with obesity in children and the development of neuropsychological deficiency confirm the role of peripheral visceral obesity and neuroinflammation.

Mechanisms Involved in Epileptogenesis in Alzheimer's Disease and Their Therapeutic Implications.

Epilepsy and Alzheimer’s disease (AD) incidence increases with age. There are reciprocal relationships between epilepsy and AD. Epilepsy is a risk factor for AD and, in turn, AD is an independent risk factor for developing epilepsy in old age, and abnormal AD biomarkers in PET and/or CSF are frequently found in late-onset epilepsies of unknown etiology. Accordingly, epilepsy and AD share pathophysiological processes, including neuronal hyperexcitability and an early excitatory–inhibitory dysregulation, leading to dysfunction in the inhibitory GABAergic and excitatory glutamatergic systems. Moreover, both β-amyloid and tau protein aggregates, the anatomopathological hallmarks of AD, have proepileptic effects. Finally, these aggregates have been found in the resection material of refractory temporal lobe epilepsies, suggesting that epilepsy leads to amyloid and tau aggregates. Some epileptic syndromes, such as medial temporal lobe epilepsy, share structural and functional neuroimaging findings with AD, leading to overlapping symptomatology, such as episodic memory deficits and toxic synergistic effects. In this respect, the existence of epileptiform activity and electroclinical seizures in AD appears to accelerate the progression of cognitive decline, and the presence of cognitive decline is much more prevalent in epileptic patients than in elderly patients without epilepsy. Notwithstanding their clinical significance, the diagnosis of clinical seizures in AD is a challenge. Most are focal and manifest with an altered level of consciousness without motor symptoms, and are often interpreted as cognitive fluctuations. Finally, despite the frequent association of epilepsy and AD dementia, there is a lack of clinical trials to guide the use of antiseizure medications (ASMs). There is also a potential role for ASMs to be used as disease-modifying drugs in AD.

Discrepancy in Fluid and Crystallized Intelligence: An Early Cognitive Marker of Dementia from the LASI-DAD Cohort

Background: Cognitive aging is a complex phenomenon, which comprises various cognitive skills, broadly categorized into fluid and crystallized intelligence. Crystallized intelligence (gc) tends to be maintained, as opposed to fluid intelligence (gf), which tends to decline rapidly with age. The association of the two with cognitive decline remains a matter of conjecture requiring further research. Aim: The aim of the study was to identify the variables of gc and gf from a population data of Longitudinal Aging Study in India-Diagnostic Assessment of Dementia (LASI-DAD) study and investigate its relationship with the onset of cognitive impairment using discrepancy analysis against neuropsychological tests. Methods: This analysis of data from LASI-DAD study was carried out on a sample of 3,223 participants. They were assessed on extensive thirteen cognitive tests and one subjective test of cognition. Standardized score was used for discrepancy analysis. Fluid ability minus crystallized ability was used to assess the cognitive impairment. Any statistical significance with the score difference >0.99 SD was defined as a presence of cognitive decline. Hindi Mental Status Examination (HMSE) and the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) were used as gold standard. Results: With increased discrepancy score, each cognitive parameter score declined which was found to be statistically significant. In HMSE (Normal = 25.81 ± 3.39; Impaired = 23.17 ± 3.54; p = <0.001), there was a drop of 2 point scores in identifying cognitive impairment in the population sample as per the gold standard. A similar trend was evident in other neurocognitive domains as well. Conclusion: Crystallized-fluid intelligence discrepancy analysis has a strong potential in predicting the onset of cognitive decline ahead of time, facilitating early intervention.

MR volumetry in detection of brain atrophic changes in MS patients and its implication on disease prognosis: retrospective study

BackgroundMultiple sclerosis is a chronic demyelinating disease of the central nervous system. It may lead to disability and cognitive impairment. Our study aimed at evaluation of the role of MR volumetry technique in detection of brain atrophic changes in patients with multiple sclerosis and its impact on disease prognosis.ResultsThis study was carried out on thirty healthy control with mean age 26.23 years and thirty patients with remitting relapsing multiple sclerosis, with a mean age of 28.18 years. Patients with multiple sclerosis were distributed across six subgroups based on the z-score cut-off of − 1.96 for regional and whole brain atrophy. We found that 2 patients (6.6%) showed no thalamic or brain atrophy, 28 patients (93.3%) showed whole brain atrophy only and 10 patients (33.3%) showed both, thalamic and BP atrophy. No patients showed only thalamic atrohy, 4 patients showed whole brain atrophy with other structure atrophy rather than thalamus (13.3%), 10 patients with whole brain and more than one structure atrophy (33.3%). Relation between subgroups and degree of increase in the Expanded Disability Status Scale (EDSS) as well as presence of cognitive decline were assessed. No significant relation were found between RRMS patients subgroups with whole brain atrophy, subgroup with isolated thalamic atrophy or subgroup with multiple structure atrophy and increase of EDSS or cognitive decline.ConclusionWe found that MRI volumetry is a very useful technique in the assessment of the atrophic changes that occur as a consequence of multiple sclerosis affecting the whole brain, deep grey matter as well as corpus callosum. Although our study did not prove significant relation between presence of brain atrophic changes and disability or cognitive impairment, presence of atrophy warrants careful clinical evaluation of those patients to detect any possible further progression of disability or cognitive decline.

Clinical benefit of combined assessment of physical and psychological frailty in patients with heart failure.

Physical frailty becomes a robust risk factor in patients with heart failure (HF) and coexistence of physical and psychological frailty is likely to be a prognostic indicator. This study aimed to analyze the prognosis of coexistence of these two factors in patients with HF. This study was a secondary analysis of a multicenter prospective cohort study (FLAGSHIP). We analyzed data from 2502 patients with HF from the FLAGSHIP study in Japan. We divided the patients into four physical frailty categories using a frailty score ranging from 0 to 14 (<4: I, 4-8: II, 9-12: III, and 14: IV, the score 13 does not exist in calculation). The higher category indicates more severe physical frailty. Psychological frailty was defined as the presence of cognitive decline and/or depressive symptoms. The study outcome was a 2-year composite outcome of rehospitalization for HF or all-cause mortality after hospital discharge. During the 3734.7 person-year follow-up, 774 patients experienced the composite outcome. After adjusting for confounders, physical and psychological frailty were independently associated with adverse outcomes. Using physical frailty category I, without psychological frailty as the reference, adjusted hazard ratios for adverse outcomes were 1.29 [95% confidence interval (CI) 0.86-1.92] for category I with psychological frailty, 0.99 (95% CI 0.71-1.37) for category II without psychological frailty, 1.61 (95% CI 1.16-2.23) for category II with psychological frailty, 1.56 (95% CI 1.14-2.15) for category III without psychological frailty, 1.62 (95% CI 1.20-2.20) for category III with psychological frailty, 1.50 (95% CI 1.05-2.14) for category IV without psychological frailty, and 2.16 (95% CI 1.59-2.94) for category IV with psychological frailty, respectively. Combined assessment of physical and psychological frailty leads to more detailed risk stratification of patients with HF.

Associação entre deficiência de zinco e declínio cognitivo em idosos da comunidade

Abstract This is a cross-sectional study evaluating the association between zinc deficiency and cognitive decline in 591 community-dwelling older adults living in the cities of Campinas, Limeira, and Piracicaba-SP. Cognitive status was evaluated using the Cognitive Abilities Screening Instrument-CASI-S, considering a decline for scores &lt;23 for those aged 60-69 and &lt;20 for those aged ≥70 years. Among the evaluated cognitive domains, older adults with zinc deficiency had significantly lower mean scores on the memory test (p=0.018). For zinc deficiency, values below 70 µg/dL were considered for women and 74 µg/dL for men. The prevalence of zinc deficiency was 3.9%, and cognitive deficit was 9.4%, being significantly higher in those with zinc deficiency compared with those with normal serum zinc concentrations. In adjusted multiple logistic regression analysis, the factors that remained associated with cognitive decline were zinc deficiency (OR=3.80; 95%CI=1.30-11.12), low schooling level (OR=3.12; 95%CI=1.49-6.50), lack of a partner (OR=1.88; 95%CI=1.04-3.42), risk of malnutrition (OR=3.98; 95%CI=2.36-6.71), and a history of encephalic vascular accident (OR=2.70; 95%CI=1.04-6.98). Zinc deficiency was associated with the presence of cognitive decline in older adults. Actions in primary health care are necessary to prevent the deficiency of this nutrient.

FATORES DE RISCO PARA DOENÇAS CARDIOVASCULARES E ESTADO COGNITIVO EM IDOSOS DO SUDOESTE DO PARANÁ

The aging process causes miscellaneous changes in the human body, including neurological changes, such as the decline in cognitive capacity. Studies report a probable relationship between cardiovascular disease (hereinafter, CVDs) and dementia, as both share common risk factors. This study aimed to evaluate the frequency of risk factors for cardiovascular diseases and cognitive status in elderly people of the southwestern Parana. Cross-sectional, quantitative study carried out with elderly people, both sexes, aged 60 or over, residing in three municipalities of the Southwest Region of Parana. Sociodemographic and clinical statistical data were realized through interviews. Cognitive assessment was measured using the Mini Mental State Examination – (hereinafter, MMSE) and the functional capacity of the research participants was assessed using the Pfeffer questionnaire – (QPAF). The risk of cardiovascular diseases was assessed by factors as: lifestyle, medical history and waist circumference (WC). The research data was composed by 82 elderly people, being 74.4% of them female, with a prevalence of age between 60 and 70 years. Of the interviewees, were 7.3% smokers, were 68.3% sedentary and 48.8% reported having cardiovascular disease. The presence of cognitive decline was present in 20.7% of the elderly and the frequency of risk for cardiovascular diseases, assessed by WC, was observed in 87.8% of the sample. This frequency of risk factors for cardiovascular diseases was elevated in the studied sample, however there was no association with the presence of cognitive decline.

PREVALENCE OF COGNITIVE DECLINE IN PATIENTS WITH STROKE

Objective: To determine the prevalence of cognitive decline among the patients of stroke and analyze the associated socio demographic factors.&#x0D; Study Design: Cross sectional study.&#x0D; Place and Duration of Study: Tertiary care hospital of Rawalpindi, from May 2018 to Aug 2018.&#x0D; Methodology: The sample population comprised of n=180 patients of hemorrhagic or ischemic stroke presenting at a tertiary care hospital in Rawalpindi, Pakistan. Cognitive decline was assessed by using the British Columbia Cognitive Complaints Inventory (BC-CCI) four weeks after the acute stroke. Relationship of age, gender, marital status, education, type of stroke, presence of physical impairment and tobacco smoking was assessed with the presence of cognitive decline among the patients of stroke.&#x0D; Results: Out of 180 patients of stroke screened through British Columbia Cognitive Complaints Inventory, 129 (71.7%) showed the presence of cognitive decline while 51 (28.3%) had no cognitive decline. After applying the logistic regression we found that female gender and presence of physical impairment had significant association with the presence of cognitive decline among the patients of stroke.&#x0D; Conclusion: This study showed a high prevalence of cognitive decline among the patients of stroke in Pakistan. Routine screening for cognitive decline should be done at the stroke follow up clinic and special attention should be paid to the female patients of stroke and those with physical impairment.

Estimation of Cognitive Performance Based on Premorbid Intelligence in Parkinson's Disease.

Background:The estimation of premorbid intelligence (PI) is needed for an accurate diagnosis.Objective:This study aimed to estimate the cognitive performance taking into account the PI in Parkinson’s disease (PD) compared to healthy controls (HC); and to analyze the discrepancies between the current and the predicted cognitive performance based on the PI.Method:Semantic fluency, verbal and visual memory, and executive functions were assessed in 39 PD and 162 HC. A linear regression model was used to analyze the discrepancies between the predicted cognitive performance and the current raw scores through PI variables (Word Accentuation Test (WAT), Pseudo-Words (PW) Reading subtest from PROLEC-R, age, and years of education). ROC analyses were performed to assess their diagnostic properties.Results:Significant differences were found in the raw cognitive scores between patients and HC [semantic fluency (t = 6.07; p < 0.001), verbal memory (t = 6.63; p < 0.001), and executive functions (t = 2.57; p = 0.013), and in visual memory (t = 1.97; p = 0.055 marginally significant)]. Compared to HC, PD patients presented higher discrepancies between the predicted cognitive performance and the raw scores in semantic fluency, verbal memory, visual memory, executive functions (AUC = 0.78, 0.78; 0.64, 0.61, respectively).Conclusion:The magnitude of the discrepancies scores between the current and the predicted cognitive performance based on PI indicates the presence of cognitive decline in the specific cognitive domain in PD patients. This study underlines the usefulness of premorbid measures and variables, such as WAT, PW, age, and years of education, to more accurately estimate the cognitive performance in PD.

INFLUENCE OF SLEEP DISTURBANCES ON COGNITIVE DECLINE IN PATIENTS WITH PARKINSON’S DISEASE

The article summarizes the arguments and counter-arguments within the scientific discussion on the impact of sleep disorders on the development of cognitive decline in patients with Parkinson's disease. The main purpose of the study is to study the possibility of predicting the development of cognitive decline by assessing the severity of sleep disorders and their differences in the presence of cognitive impairment. Systematization of literature sources and approaches to solving the problem showed that sleep disorders develop in the early stages of Parkinson's disease and are often accompanied by cognitive impairment. Cognitive decline is manifested throughout Parkinson's disease and ranges from moderate in the early stages to dementia in the late stages. The relevance of the study of the relationship between sleep disorders and cognitive functions lies in the possibility of further improving the prediction of the development of cognitive decline in order to effectively correct it. Treatment of sleep disorders can be accompanied by improved memory and even morphological changes in the brain. Therefore, the question arises about the possibility of correcting cognitive decline by influencing sleep disorders. The methodology of the study included assessment of the overall status of patients on a unified scale of Parkinson's disease, Montreal cognitive rating scale and sleep scale in Parkinson's disease. The duration of the study was 8 months. Patients with Parkinson's disease were selected as the study. The article presents the results of a survey of patients who show that patients with Parkinson's disease and cognitive decline showed a predominance of motor disorders, sleep disorders and the overall score on the sleep scale in Parkinson's disease. In the presence of cognitive decline more pronounced disorders of motor functions in everyday life, which can lead to sleep disorders and its quality. The study empirically confirms and theoretically proves that the assessment of sleep disorders can be used to predict the risk of developing cognitive impairment in patients with Parkinson's disease. The results of this study may be useful for improving the early diagnosis and prevention of cognitive impairment in patients with Parkinson's disease, which, in turn, leads to improved quality of treatment of these patients. Such changes can directly affect the choice of therapeutic tactics and improve the quality of life of patients with Parkinson's disease. The question of the features of various sleep disorders and their prognostic value in relation to cognitive decline in patients with various forms of Parkinson's disease remains open.

296Clinical benefit of assessing cognitive function in frail patients with heart failure: a multicenter prospective cohort study

Abstract Background Cognitive decline is highly prevalent in patients with heart failure (HF) and increases the risk of hospital readmission or mortality due to poor self-care ability. Although cognitive decline often coexists with physical frailty (PF) in HF, the clinical utility of combined assessment of both cognitive function and PF remains unclear. Purpose The aim of this study was to examine the prognostic value of assessing cognitive function and PF in patients with HF. Methods This prospective study was performed as a multicenter cohort study in Japan (FLAGSHIP). We enrolled 1611 patients admitted for acute HF or exacerbation of chronic HF and who were able to walk at discharge. Patients with severe dementia [Mini-Mental State Examination (MMSE) scores &lt;18], severe psychological disorders or less than 6-month life expectancy were excluded. From data at discharge, we collected data on cognitive function, PF, age, gender, New York Heart Association class, left ventricular ejection fraction, brain natriuretic peptide, estimate glomerular filtration rate, hemoglobin, depression (5-item geriatric depression scale ≥2) and comorbidities, including atrial fibrillation, diabetes mellitus, stroke, and hyponatremia. PF was defined as ≥2 of the followings based on our previous publication: usual walking speed &lt;0.8 m/s; grip strength &lt;26 kg (men) or &lt;17 kg (women); Performance Measure of Activity in Daily Living-8 ≥21; body mass index &lt;20 kg/m2. Cognitive function was assessed by MMSE. We selected the optimal cutoff point of MMSE that predict a worse outcome by the receiver operating characteristic (ROC) curve analysis. Study outcome was a composite outcome of rehospitalization for worsening HF or all-cause mortality within 2 years after discharge. We used Cox proportional-hazard models to examine the association between the presence of cognitive decline and PF and 2-years prognosis, controlling for potential confound factors. Results A total of 507 events (31.5%) were observed (400 HF rehospitalization, 27 cardiac death, 80 non-cardiac death). The optimal cutoff point of MMSE was 28 (the area under the ROC curve: 0.58, p&lt;0.01, sensitivity: 71.0%, specificity: 41.0%). There was a significant difference in event-free survival across the groups stratified by cognitive decline (MMSE &lt;28) and PF (Figure). After adjusting for all variables, coexistence of both cognitive decline and PF was independently associated with 2-years prognosis (hazard ratio: 1.52, 95% confidence interval: 1.19–1.94). Conclusion Our data shows that even a slight decline in cognitive function leads to an increased risk of death or HF rehospitalization in frail patients with HF. Combined assessment both cognitive function and PF improves risk stratification for readmission and mortality in patients with HF.

Qualitative Scoring of the Pentagon Test: A Tool for the Identification of Subtle Cognitive Deficits in Isolated REM Sleep Behavior Disorder Patients.

Isolated rapid eye movement (REM) sleep behavior disorder (iRBD) frequently represents the prodromal stage of alpha-synucleinopathies, and similar to these pathologies, iRBD patients show neuropsychological deficits, particularly in the domain of visuospatial abilities and executive functions. We hypothesized that the qualitative scoring of the Mini-Mental State Examination pentagon test (QSPT) may detect subtle visuospatial deficits in these subjects, and we evaluated its relationship with indexes of sleep quality, as measured by polysomnography. A total of 80 polysomnography-confirmed iRBD patients and 40 healthy controls (HCs) were retrospectively recruited. Global and specific qualitative performances were evaluated according to QSPT procedure. Comparisons between iRBD and HC regarding all QSPT parameters, neuropsychological tests, and polysomnographic recordings were performed. Patients displayed significantly lower scores in both "closing-in" and total score parameters in comparison to HC. The QSPT total score exhibited significant positive correlations with verbal comprehension, fluency, visuospatial abilities, and executive functions. Notably, iRBD patients with impaired performance at QSPT showed decreased neuropsychological performances and higher percentages of slow wave sleep (SWS). In addition, SWS percentages negatively correlated with verbal comprehension, fluency, visuospatial abilities, executive functions, and QSPT total score. QSPT may represent a brief and easy to administer tool for the detection of subtle visuospatial changes in iRBD patients. Furthermore, polysomnographic findings suggest a possible slowdown of electroencephalographic pattern during non-REM sleep in iRBD patients in line with the presence of cognitive decline.

Vestibular rehabilitation in older adults with and without mild cognitive impairment: Effects of virtual reality using a head-mounted display

PurposeDue to the gap in the knowledge in the field of vestibular rehabilitation the purpose of this randomized study is to highlight the outcomes of head-mounted display (HMD) implementation in older adults and patients with mild cognitive impairment (MCI), suffering from unilateral vestibular hypofunction (UVH). Materials and methodsVestibulo-ocular reflex (VOR) gain, postural sway examination and dizziness-related and quality of life scores were collected in 12 UVH elderly and 12 UVH subjects suffering from MCI only undergoing vestibular rehabilitation and in 11 UVH elderly and 12 UVH subjects suffering from MCI undergoing a home-based HMD + vestibular rehabilitation protocol. ResultsAlthough the within-subjects analysis found in all groups a significant (p < 0.05) improvement in posturography parameters and dizziness-related and quality of life scores and no changes in VOR gain, implementation of HMD demonstrated a significant (p < 0.05) increase in post-treatment between-group comparisons in the same tests and VOR gain with respect to those older adults and participants with MCI only undergoing vestibular rehabilitation. Positive correlations were discovered between Mini-Mental Score Exam values and pre-/post-treatment differences in (i) power spectra values in the low-frequency interval (r = 0.72) and in (ii) Dynamic Gait Index scores (r = 0.76). ConclusionsThis study demonstrates that the implementation of a home-based virtual reality protocol may be a safe option in order to ameliorate VOR, postural control and the quality of life also in the vestibular impaired patients in whom the presence of cognitive decline could hinder the achievement of the goal of rehabilitation.

“Ours is the Strangest Situation, Ours is Different from Most Peoples”: Spousal Caregiver Perspectives on the Complex Challenges of Dementia Caregiving in Late-Life Marriage

The relationship between the person with dementia with family caregivers is a key factor in maintaining a sense of self and personhood. Spousal caregiving in particular can create a world of shared meaning, and in the context of the presence of cognitive decline in one spouse, couple hood is essential to a full understanding of how spouses live with and respond to the impact of dementia. While much research has focused on the strengths of long-term married couples caring for a spouse with dementia, there is currently little research on how dementia impacts couples in late-life marriage. This qualitative case study focusses on two female caregivers in late-life marriages negotiating the challenges of caregiving for a spouse with dementia. Spouse 1 returned to live with her ex-husband in order to care for him through his dementia journey and they recently remarried. Spouse 2 married a close friend of the family prior to his dementia diagnosis. While participant shared perspectives include: (1) family dynamics, (2) isolation, (3) financial concerns, and (4) acceptance of their role in their spouse’s dementia journey, their long-term outlooks are divergent due to the complexity of their motives for entering in to late-life marriage.

Capacidade cognitiva, estilo e qualidade de vida dos idosos: estudo transversal

Aim: to verify the cognitive ability, style and quality of life of elderly primary care users. Method: a cross-sectional, correlational, analytical and descriptive study with a quantitative approach. A total of 252 semi-structured questionnaires were applied to the urban elderly, containing sociodemographic information, cognitive ability assessment and questions regarding style and quality of life. Result: there was a predominance of females with low schooling, presence of cognitive decline in 68.25% (n=172) of the elderly and a significant association between the Health Units (p=0,0351). Discussion: it should be pointed out that elderly people who do not present a decline have a better score in the nutrition component, this data emphasizes that maintaining good eating habits positively influences cognitive ability. Conclusion: the interviewees are young elderly with cognitive decline. Emphasis is given to the importance of nurses acting as health promoters, favoring active aging.

Cognitive Changes After Adjuvant Treatment in Older Adults with Early-Stage Breast Cancer.

Group-based trajectory modeling is particularly important to identify subgroups of patients with pathological cognitive changes after cancer treatment. To date, only one study has explored cognitive trajectories in older patients with cancer. The present article describes objective cognitive changes before to after adjuvant treatment in older adults with early-stage breast cancer (EBC) after adjuvant treatment compared with healthy controls. Participants were patients ≥65 years of age with newly diagnosed EBC and healthy controls (age-, sex-, and education-matched). The pretreatment assessment was conducted before adjuvant therapy, and the post-treatment assessment after the end of the first adjuvant treatment. Objective cognitive changes before to after treatment were evaluated based on the Reliable Change Index for cognitive decline accounting for cognitive impairment status. The sample consisted of women newly diagnosed with EBC (n = 118) and healthy controls (n = 62). Five patterns of changes before to after treatment were identified based on the presence of cognitive decline and cognitive impairment. The distribution of these five change patterns was statistically significant (p = .0001). Thirty-six percent of patients had phase shift changes, 31% without initial objective cognitive impairment developed impairment, 15% had a normal aging, 12% had a nonpathological decline, and 6% experienced accelerated cognitive decline. This study described for the first time objective cognitive changes before to after treatment of older adults with EBC immediately after the end of adjuvant treatment. A longer-term remote follow-up of adjuvant treatment is needed to better understand the cognitive trajectories of older patients with EBC. After the end of adjuvant treatment, 31% of older adults with early-stage breast cancer without initial objective cognitive impairment developed impairment, and 6% experienced accelerated cognitive decline. Initial cognitive functioning should be included in the balance of benefits and harms of systemic therapy for patients who are likely to be at highest risk for cognitive decline after cancer treatments. Regular cognitive follow-up of patients who had cognitive impairment before cancer treatment should monitor symptoms suggestive of neurodegenerative disease and avert the effect of cognitive disorders on patients' autonomy.

Association between Periodontal Health Status and Cognitive Abilities. The Role of Cytokine Profile and Systemic Inflammation.

Background: Contemporary neurobiology, periodontal medicine, and immunology are now focusing on the relationship between chronic periodontitis and systemic diseases, which also include Alzheimer’s disease (AD). However a causative relationship between dementia and periodontitis has yet to be confirmed.Objective: The aim of the study was to determine whether periodontal health status and cognitive abilities are correlated with the relative changes in systemic measures of pro- and anti-inflammatory cytokines as a reflection of systemic inflammation. We hypothesized that poor periodontal health status may be associated with cognitive impairment and dementia via the exacerbation of systemic inflammation.Methods: Based on the periodontal and psychiatric examinations and the cytokine levels produced by unstimulated and LPS-stimulated PBL isolated from 128 participants, we have examined if the coexisting of these two clinically described conditions may have influence on the systemic inflammation. Mini-Mental State Examination (MMSE) and Bleeding on Probing (BoP) test results were combined into the one mathematical function U, which determines the severity of specific condition, called Cognitive and periodontal impairment state. Similarly, the levels of cytokines were combined into the one mathematical function V, whose value determines the level of Inflammatory state. The correlation between U and V was determined.Results: These results confirm that the presence of cognitive decline and the additional source of pro-inflammatory mediators, like periodontal health problems, aggravate the systemic inflammation.Conclusion: It is most likely that the comorbidity of these two disorders may deepen the cognitive impairment, and neurodegenerative lesions and advance to dementia and AD.

Does left ventricular hypertrophy affect cognition and brain structural integrity in type 2 diabetes? Study design and rationale of the Diabetes and Dementia (D2) study

BackgroundCognitive impairment is common in type 2 diabetes mellitus, and there is a strong association between type 2 diabetes and Alzheimer’s disease. However, we do not know which type 2 diabetes patients will dement or which biomarkers predict cognitive decline. Left ventricular hypertrophy (LVH) is potentially such a marker. LVH is highly prevalent in type 2 diabetes and is a strong, independent predictor of cardiovascular events. To date, no studies have investigated the association between LVH and cognitive decline in type 2 diabetes. The Diabetes and Dementia (D2) study is designed to establish whether patients with type 2 diabetes and LVH have increased rates of brain atrophy and cognitive decline.MethodsThe D2 study is a single centre, observational, longitudinal case control study that will follow 168 adult patients aged >50 years with type 2 diabetes: 50% with LVH (case) and 50% without LVH (control). It will assess change in cardiovascular risk, brain imaging and neuropsychological testing between two time-points, baseline (0 months) and 24 months. The primary outcome is brain volume change at 24 months. The co-primary outcome is the presence of cognitive decline at 24 months. The secondary outcome is change in left ventricular mass associated with brain atrophy and cognitive decline at 24 months.DiscussionThe D2 study will test the hypothesis that patients with type 2 diabetes and LVH will exhibit greater brain atrophy than those without LVH. An understanding of whether LVH contributes to cognitive decline, and in which patients, will allow us to identify patients at particular risk.Trial registrationAustralian New Zealand Clinical Trials Registry (ACTRN12616000546459), date registered, 28/04/2016
