Stages of brain volume loss and performance in the Brief International Cognitive Assessment for Multiple Sclerosis.

BACKGROUND: Cognitive dysfunction occurs in a substantial proportion of patients with multiple sclerosis (MS), negatively affects their daily activities, and is associated with poor prognosis. Cognitive dysfunction in MS can extend across multiple cognitive domains, depending on the patterns and extent of the brain regions affected. Therefore, a combination of tests, including the Brief International Cognitive Assessment for MS (BICAMS), that assess different aspects of cognition is recommended to capture the full picture of cognitive impairment in each patient. However, the temporal relationships between the progression of the MS brain pathology and the performances in different cognitive tests remain unclear. METHODS: Global and regional brain volume data were obtained based on T1-weighted magnetic resonance imaging from 61 patients with MS, and hierarchical cluster analysis was performed using these brain volume data. Cognitive function was assessed using the three subcomponents of the BICAMS: the Symbol Digit Modalities Test (SDMT), California Verbal Learning Test Second Edition (CVLT2), and Brief Visuospatial Memory Test-Revised (BVMTR). Clinical characteristics, patterns of regional brain volume loss, and cognitive test scores were compared among clusters. RESULTS: Cluster analysis of the global and regional brain volume data classified patients into three clusters (Clusters 1, 2, and 3) in order of decreasing global brain volume. A comparison of the clinical profiles of the patients suggested that those in Clusters 1, 2, and 3 are in the early, intermediate, and advanced stages of MS, respectively. Pair-wise analysis of regional brain volume among the three clusters suggested brain regions where volume loss starts early and continues throughout the disease course, occurs preferentially at the early phase, or evolves relatively slowly. SDMT scores differed significantly among the three clusters, with a decrease from Clusters 1 to 3. BVMTR scores also declined in this order, whereas the CVLT2 was significantly impaired only in Cluster 3. CONCLUSION: Our results suggest that SDMT performance declines in conjunction with brain volume loss throughout the disease course of MS. Performance in the BVMTR also declines in line with the brain volume loss, but impairment in the CVLT2 becomes particularly apparent at the late phase of MS.

Glaucoma and cognitive function trajectories in a population-based study: Findings from the health and retirement study.

INTRODUCTION: Prior studies on the association of glaucoma and cognitive function have reported mixed results. METHODS: The Health and Retirement Study (HRS) is a nationally representative panel survey of Americans age ≥ 51 years. HRS-linked Medicare claims data were used to identify incident glaucoma cases (by glaucoma type). Cognitive function was measured using the Telephone Interview for Cognitive Status (TICS), administered in each wave (every 2 years). Separate linear mixed models were fitted with either prevalent or incident glaucoma as a predictor of TICS trajectories and adjusting for age, race/ethnicity, educational attainment, gender, and medical history. Negative model estimates indicate associations of glaucoma with worse cognitive function scores or steeper per-year declines in cognitive function scores. RESULTS: Analyses of prevalent glaucoma cases included 1344 cases and 5729 controls. Analyses of incident glaucoma included 886 cases and 4385 controls. In fully-adjusted models, those with prevalent glaucoma had similar TICS scores to controls (ß = 0.01; 95% Confidence Interval [CI]: -0.15, 0.18; p = 0.86). However, in those with incident glaucoma, we detected a statistically significant association between glaucoma and lower TICS scores (ß = -0.29; 95% CI: -0.50, -0.08; p = 0.007). However, there was no statistically significant association between either prevalent or incident glaucoma and per-year rates of change in TICS scores. When categorizing glaucoma by type (primary open angle glaucoma, normal tension glaucoma, or other glaucoma), no significant associations were detected between either prevalent or incident glaucoma and levels of or rates of change in TICS scores in fully covariate adjusted models. CONCLUSION: The observed associations between glaucoma and cognitive function were small and unlikely to be clinically meaningful. Compared to prior studies on this topic, this investigation provides robust evidence based on its larger sample size, longitudinal follow-up, and repeated measures of cognitive function in a population-based sample.

Tunisian version of the brief international cognitive assessment for multiple sclerosis: Validation and normative values.

BACKGROUND: The Brief International cognitive assessment for Multiple sclerosis (BICAMS) is a specific batterie used to identify cognitive impairment in Multiple Sclerosis (MS) in a reliable and easy way. To date, for the Arabic-speaking Tunisian MS patients, there is no consensus for the use of specific cognitive batteries in MS. OBJECTIVE: The aim of our work was to develop and validate the Tunisian version of the BICAMS (T-BICAMS) and to determine our own normative values. MATERIAL AND METHODS: Patients diagnosed with MS and followed up in the department of Neurology of Razi Hospital were recruited and matched to healthy controls according to age, sex and educational level. T-BICAMS validity was established by comparing MS and healthy controls for symbol digit modalities test (SDMT), brief visual memory test (BVMT-R) and Tunisian verbal learning tests (TVLT) which was used instead of the California verbal learning test (CVLT-II). RESULTS: The 104 MS patients and 104 healthy controls were comparable for age, sex and educational level. The MS group exhibited lower performances in all T-BICAMS domains compared to healthy controls: SDMT (x003Dp<10-3), BVMT-R (p = 0.002) and TVLT (p x003D<10-3). T-BICAMS Cronbach alpha value was 0.741. Normative values were identified for patients with MS: SDMT [39-40], BVMT-R [26-27] and TVLT [43-44]. Cognitive impairment was identified among 76 patients (73.1%). Males, lower educational levels and progressive MS were associated with a more severe cognitive impairment. CONCLUSIONS: The current study has established the BICAMS as a valid and reliable tool for the identification of cognitive impairment in the Tunisian MS population.

Pretransplant Comprehensive Geriatric Assessment in Older Patients with Advanced Chronic Kidney Disease.

BACKGROUND: In older patients with advanced chronic kidney disease (CKD), the decision of kidney transplantation (KT) is a challenge for nephrologists. The use of comprehensive geriatric assessment (CGA) is increasingly gaining interest into the process of decision-making about treatment modality choice for CKD. The aim of this study was to assess the prevalence of geriatric impairment and frailty in older dialysis and nondialysis patients with advanced CKD using a pretransplant CGA model and to identify geriatric impairments influencing the geriatricians' recommendations for KT. METHODS: An observational study was conducted with retrospective data from July 2017 to January 2020. Patients aged ≥65 years with advanced CKD, treated or not with dialysis, and referred by the nephrologist were included in the study. The CGA assessed comorbidity burden, cognition, mood, nutritional status, (instrumental) activities of daily living, physical function, frailty, and polypharmacy. Geriatric impairments influencing the geriatricians' recommendations for KT were identified using univariate and multivariate logistic regressions. RESULTS: 156 patients were included (74.2 ± 3.5 years and 62.2% on dialysis). Geriatric conditions were highly prevalent in both dialysis and nondialysis groups. The rate of geriatric impairments was higher in dialysis patients regarding comorbidity burden, symptoms of depression, physical function, autonomy, and frailty. Geriatrician's recommendations for KT were as follows: favorable (79.5%) versus not favorable or multidisciplinary discussion needed with nephrologists (20.5%). Dependence for Instrumental Activities of Daily Living (IADL) (odds ratio [OR] = 3.01 and 95% confidence interval [CI] = 1.30-7.31), physical functions (OR = 2.91 and 95% CI = 1.08-7.87), and frailty (OR = 2.66 and 95% CI = 1.07-6.65) were found to be independent geriatric impairments influencing geriatrician's recommendations for KT. CONCLUSIONS: Understanding the burden of geriatric impairment provides an opportunity to direct KT decision-making and to guide interventions to prevent functional decline and preserve quality of life.

Reading Comprehension Impairment in Children With Neurofibromatosis Type 1 (NF1): The Need of Multimodal Assessment of Attention.

Attention span, which has been shown to have an impact on reading quality in many other conditions, is one of the main cognitive disorders of neurofibromatosis type 1 (NF1). The aim of this work is to observe the impact of attention on reading comprehension, in NF1 and non-NF1 children. A multicenter, cross-sectional study was conducted on 150 children (8-12 years old) with or without NF1 (75 NF1 vs 75 non-NF1; 72 female, 78 male), matched for age, sex, handedness, and reading level, thus forming a continuum from good to poor readers in both NF1 and non-NF1 groups. Children with intellectual deficiency or neurologic or psychiatric disorder were excluded. Attentional skills were assessed by combining a parent questionnaire (Child Behavior CheckList) and a performance-based assessment (Conner's Continuous Performance Test-Second Edition). Reading comprehension was assessed through a standardized reading comprehension test (ORLEC Lobrot). The performance-based attention scores were associated with text and sentence comprehension ability (P = .0235 and P = .0164, respectively), while indirect questionnaire attention scores were only associated with sentence comprehension (P = .0263). For both groups, the correlations between questionnaire and performance-based measures were low. We have shown that reading comprehension is greatly influenced by attention in NF1 and non-NF1, even if predictors of good reading comprehension also include IQ score and reading accuracy. Indirect observer-rated questionnaires and direct performance-based measures of attention do not assess the same variables, are linked to different components of reading skills, and are not interchangeable assessments of attention difficulties. Both assessments are complementary and must be used simultaneously, leading to recommendations that support multimodal assessment of attention.

Factors associated with functional loss among community-dwelling Mexican older adults. / Factores asociados con el deterioro funcional en adultos mayores mexicanos

INTRODUCTION: Functional status decline is related to many negative outcomes. OBJECTIVE: To explore the relationship of sociodemographic, medical, and psychological factors with the incidence of functional status decline in Mexican older adults. MATERIALS AND METHODS: Data from the 2012 and 2015 waves of the Mexican Health and Aging Study (MHAS) survey were analyzed. Participants with previous functional status decline at baseline were excluded. We assessed functional status decline individually with activities of daily living (ADL) and instrumental ADL (IADLs) in an individual way. RESULTS: Age was associated with functional limitations in ADL. Being male had an association with limitations for IADL. A poor financial situation and lower education related to higher limitations for ADL. Furthermore, pain, comorbidities, and depression were found to be independently associated with limitations in ADL. IADL limitation was associated with age, poor education, comorbidities, and depression, as well as cognitive impairment. CONCLUSIONS: We found that factors such as age, financial status, educational level, pain, and the number of comorbidities were associated with the incidence of functional status decline. Pain had a greater association in the 3-year functional ADL decline incidence when compared with cognitive impairment. Studying functional decline by domains allowed us to find more detailed information to identify factors susceptible to intervention with the aim to reduce the incidence of functional status decline and dependence.

Introducción. El deterioro funcional está relacionado con muchos resultados adversos. Objetivo. Explorar la relación de los factores sociodemográficos, médicos y psicológicos con la incidencia del deterioro funcional en los adultos mayores mexicanos. Materiales y métodos. Se analizaron los datos de las cohortes de 2012 y 2015 de la encuesta del Estudio Mexicano de Salud y Envejecimiento. Se excluyeron los participantes con discapacidad funcional en el período de referencia (2012). Se evaluó de forma individual el deterioro funcional en las actividades básicas de la vida diaria (AVD) y en las instrumentales (AIVD). Resultados. Se encontró que el dolor, las comorbilidades, el nivel educativo, el estatus socioeconómico y la depresión se asociaban independientemente con el deterioro de las AVD. El deterioro de las AIVD se asoció con la edad, la educación deficiente, las comorbilidades, la depresión y el deterioro cognitivo. Conclusiones. La edad, el sexo, el estado financiero, el nivel educativo, el dolor y el número de comorbilidades se asociaron con la incidencia del deterioro funcional. El dolor tuvo una mayor asociación con la incidencia del deterioro funcional en las AVD a los tres años, en comparación con el deterioro cognitivo. El estudio del deterioro funcional por dominios permitió recabar información más detallada para determinar los factores que pueden intervenirse con el objetivo de reducir la incidencia del deterioro funcional y la dependencia.

[Ethics, care and ageing during the Covid-19 pandemic]. / Éthique, soin et grand âge pendant l'épidémie de Covid-19.

At the beginning of the Covid-19 epidemic, National forum for ethical reflection on Alzheimer's disease and neurodegenerative diseases conducted a national survey to identify the difficulties encountered by professionals working in the field of old age and autonomy, families and volunteers, and the initiatives they have implemented. Seven major difficulties were identified: the isolation induced by the prohibition of visits, the lack of protective equipment and tests, the difficulties of people with cognitive difficulties in understanding measures to avoid the spread of the epidemic, the sustainability of overwork for professionals, the concern of the families of residents, complex situations at home and difficulties in accessing care. Four initiatives are being implemented: information and training for teams, compensation for interrupted visits, consultations and exchanges between professionals, actions to benefit people living at home. The Covid-19 epidemic hit the elderly sector at a very special moment in its history, several years of effort by the sector to reinvent itself around strong values. They have been a resource during this period of crisis. An ambitious law on old age and autonomy therefore appears to be a necessity.

Performance on the standard and hearing-impaired Montreal Cognitive Assessment in cochlear implant users.

OBJECTIVES: Commonly used cognitive screening tools were not originally developed for patients with hearing loss (HL) and rely heavily on the ability to hear the instructions and test stimuli. Recently, the Montreal Cognitive Assessment (MoCA) was modified for use with hearing-impaired populations (ie, HI-MoCA). In order to investigate the clinical utility of the HI-MoCA, we assessed performance between the standard MoCA and HI-MoCA among postlingually deafened cochlear implant (CI) users. METHODS: We administered the standard MoCA and HI-MoCA to 21 CI users and compared their performance. We assessed differences in pass/fail status when items from the attention and language sections and the delayed recall task were removed. RESULTS: There was no significant difference in performance between the standard MoCA and HI-MoCA. Participants scored higher on both test versions when the delayed recall task was removed. Participants also performed better on the delayed recall task on the HI-MoCA than on the standard MoCA. CONCLUSIONS: While our findings suggest that the modality of presentation for the MoCA does not influence overall performance for postlingually deafened CI users, visual presentation of stimuli impacted performance on delayed recall. Furthermore, irrespective of presentation modality, our participants scored higher on both MoCA versions when the delayed recall task was removed. Clinically, modifications to the presentation of the MoCA might not be necessary for CI users; however, clinicians should be aware that the delayed recall task is inherently harder for these patients.

[Profiles of loneliness and social isolation in urban population]. / Perfiles de soledad y aislamiento social en población urbana.

OBJECTIVE: To assess the prevalence of loneliness and social isolation in a population over 65 cared by a urban primary health team and to identify its main characteristics. DESIGN: Cross-sectional descriptive study by a telephone survey. SETTING: Basic health area of Barcelona. PARTICIPANTS: Random sample of assigned population of 65 or more years old. MAIN MEASUREMENTS: UCLA Loneliness Scale and Lubben Social Network Scale. RESULTS: 278 persons were interviewed (61,36% response rate), 172 women and 106 men, with an average age of 76,7 ± 7,9 years. A higher proportion of factors related to loneliness were identified in non-respondents. Loneliness was closely correlated to social r = 0,736. Moderate loneliness, with a prevalence of 16,54%, was associated to walking difficulties (OR 3,09, 95%, IC 1,03-9,29), cognitive impairment (OR 3,97, 95% IC 1,19-13,27) and architectural barriers (OR 5.29, 95% IC 2.12-13,23), although severe loneliness, with a prevalence of 18,71% was only associated to living together with less people (OR 0.61, 95% IC 0.40-0.93). Social isolation, with a prevalence of 38,85% was associated to aging (OR 1,06, 95% IC 1,02-1,10) and to the belief of having health problems (OR 4,35, 95% IC 1,11-16,99). CONCLUSIONS: Loneliness and social isolation are of high prevalence. The telephone survey underestimates its prevalence. There are 2profiles of loneliness, one with moderate associated to the socialisation difficulties related to aging and another severe not related to health or to barriers that only can be identified by surveys or clinical interview. Interventions must be targeted to each of these profiles.

[Assessment and treatment of cognitive impairments in patients with affective disorders].

Many patients with affective disorders have cognitive impairments during remission, which impede their functional recovery and quality of life. The International Society for Bipolar Disorders Targeting Cognition Task Force recommends that clinicians screen for cognitive impairments, when patients are in remission using subjective and objective screening tools. Clinicians should evaluate, whether any impairments are secondary to comorbidity, medication or unhealthy lifestyle. Information to patients and their relatives about how to tackle cognitive impairments can improve daily life functioning.

[Pain assessment of nursing home's residents by certified nursing assistants: a real-world study]. / Évaluation de la douleur des résidents en Ehpad par des aides-soignantes : une étude en condition écologique.

In French care facilities for dependent aged people (NHDAP), prevalence of pain among residents with dementia is high, and source of behavior disturbances and quality of life impairment. However, in spite of many international expert statements, pain remains under-assessed and under-managed in these patients. Certified nursing assistants (CNA) are on the front-line in NHDAP to detect the presence of pain in residents with communication difficulties, while they received little training for pain management and directives for specific care. Moreover, no studies were presently devoted to the impact of demographic and socio-professional determinants of CNA on pain assessment. In our study, we assessed the presence and intensity of pain in cognitively impaired residents in NHDAP, by CNA performing as a pair for the morning care. 42 pairs were recruited and independently completed a standardized behavioral assessment for pain (Doloplus scale) as well as a numeric rating scale. CNA personal characteristics were investigated to analyse the determinants of potential assessment discrepancies between each of the pairs. Presence of pain was detected in 51.1 to 91.1% of the patients depending on the tool and analysis criteria. In 28.9% important discrepancies were observed in the pain assessment between the CNA pairs, which could be related to professional status and prior use of the observational assessment. These inter-rater discrepancies should be reduced providing clear pain assessment guidelines for CNA in NHDAP, and further studies should be completed to figure out the role of CNA personal determinants in the patients' pain assessment.

Motoric cognitive risk syndrome and cardiovascular diseases and risk factors in the Canadian population: Results from the baseline assessment of the Canadian longitudinal study on aging.

BACKGROUND: Motoric Cognitive Risk Syndrome (MCR) is a pre-dementia syndrome. The aim of this study was to examine whether there is: 1) an association between MCR and cardiovascular diseases and risk factors (CVDRF) in the Canadian population, and 2) a specific MCR-related CVDRF profile (i.e., cardiovascular diseases (CVD) versus cardiovascular risk factors (CVRF) versus both) when comparing different age groups. METHODS: A total of 29,569 participants free of dementia were recruited in the Canadian Longitudinal Study on Aging. Participants were categorized into groups by their age and MCR status (with MCR versus without MCR). Overweight/obese, smoking, waist to hip circumference ratio (WHCR), systolic blood pressure and diastolic blood pressure levels were CVRF. Diabetes type I and II, hypertension, heart disease and attack, peripheral vascular disease, angina, stroke and rhythmic disease were CVD. RESULTS: A higher prevalence of CVRF in MCR was shown in the youngest age groups (i.e., 45-54 and 55-64) compared to the other age groups. MCR was positively associated with CVDRF, except in the oldest age group (i.e., ≥75). In this group, the only significant association with CVRF was with diastolic blood pressure, which was negatively associated with MCR. Diabetes and hypertension were not associated with MCR. CONCLUSIONS: MCR is associated with CVDRF in both younger and older individuals. A stronger association was present for CVRF factors in younger adults and for CVD in older adults.

Cognitive deficits in progressive supranuclear palsy on the Repeatable Battery for the Assessment of Neuropsychological Status.

Progressive supranuclear palsy (PSP) is associated with a variety of cognitive deficits, as well as motor and psychiatric disturbances. As clinical trials for PSP evolve, briefer screening instruments will be needed to determine cognitive effects of interventions. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) may fill this gap. Three hundred four participants diagnosed with Richardson's syndrome of PSP were evaluated with the RBANS, as well as other scales typically used in PSP. RBANS performances for these participants fell significantly below expectations for the Total Scale score and all five Indexes. Cognitive scores on the RBANS were also significantly related to other markers of PSP (e.g., motor and functional abilities, depression, global cognition). Compared to other clinical conditions from the literature, patients with PSP show impairment on tests of visuospatial perception and construction and attention. Although additional research is needed, the current study supports the clinical applicability of the RBANS in patients with PSP, as well as its potential for future clinical trials.

Widespread Cognitive Deficits in Alcoholism Persistent Following Prolonged Abstinence: An Updated Meta-analysis of Studies That Used Standardised Neuropsychological Assessment Tools.

OBJECTIVE: This study presents an updated meta-analysis replicating the study of (Stavro, K., Pelletier, J., & Potvin, S. (2013). Widespread and sustained cognitive deficits in alcoholism: A meta-analysis. Addiction Biology, 18, 203-213. doi:10.1111/j.1369-1600.2011.00418.x) regarding the cognitive functioning of alcoholics as a function of time abstinent. METHODS: A total of 34 studies (including a total of 2,786 participants) that met pre-determined inclusion and exclusion criteria were included in the analyses. The alcoholics were categorised into recently detoxified alcoholics (0-31 days sober), alcoholics 32-365 days sober and alcoholics >365 days sober consistent with the previous study. The current study employed more stringent control on the tests included in the analysis to include only those tasks described in contemporary neuropsychological test compendia. Forty-seven percent of the papers surveyed were not include in the previous meta-analysis. RESULTS: The results indicated that there was a diffuse and pervasive pattern of cognitive deficit among recently detoxified alcoholics and that these deficits, particularly with regard to memory functioning, persisted even in longer term abstinent alcoholics. This was inconsistent with the prior meta-analysis which contended that significant cognitive recovery was possible after as little as 1 year. CONCLUSION: The persisting cognitive deficits were noted across a wide range of cognitive functions, supporting the notion of a diffuse rather than a specific compromise of cognition in alcoholism following discontinuation, as measured using standardised neuropsychological tests. Limitations on the finding included the fact that it was a cross-sectional rather than a longitudinal analysis, was subject to heterogeneity of method, had low representation of females in the samples, and had fewer studies of long-term sober samples.

The effect of preoperative cognitive impairment and type of vascular surgery procedure on postoperative delirium with associated cost implications.

OBJECTIVE: Postoperative delirium (POD) has a high prevalence among vascular surgery patients, increasing morbidity, mortality, and length of stay. We prospectively studied preoperative risk factors for delirium that can be assessed by the surgical team to identify high-risk patients and assessed its impact on hospital costs. METHODS: There were 173 elective vascular surgery patients assessed preoperatively for cognitive function using the Montreal Cognitive Assessment (MoCA) and the Confusion Assessment Method for POD, which was verified by chart and clinical review. Demographic information, medications, and a history of substance abuse, psychiatric disorders, and previous delirium were prospectively recorded. An accompanying retrospective chart review of an additional 434 (elective and emergency) vascular surgery patients provided supplemental cost information related to sitter use and prolonged hospitalization secondary to three factors: delirium alone, dementia alone, and delirium and dementia. RESULTS: Prospective screening of 173 patients (73.4% male; age, 69.9 ± 10.97 years) identified that 119 (68.8%) had MoCA scores <24, indicating cognitive impairment, with 7.5% having severe impairment (dementia). Patients who underwent amputation had significantly (P < .000) lower MoCA scores (17 of 30) compared with open surgery and endovascular aneurysm repair patients (23.7 of 30). The incidence of delirium was 11.6% in the elective cohort. Regression analysis identified predictors of delirium to be type of surgical procedure, including lower limb amputation (odds ratio [OR], 16.67; 95% confidence interval [CI], 3.41-71.54; P < .000) and open aortic repair (OR, 5.33; 95% CI, 1.91-14.89; P < .000); cognitive variables (dementia: OR, 5.63; 95% CI, 2.08-15.01; P < .001); MoCA scores ≤15, indicating moderate to severe impairment (OR, 6.13; 95% CI, 1.56-24.02; P = .02); and previous delirium (OR, 2.98; 95% CI, 1.11-7.96; P = .03). Retrospective review (N = 434) identified differences in sitter needs for patients with both delirium and dementia (mean, 13.6 days), delirium alone (mean, 3.9 days), or dementia alone (mean, <1 day [17.7 hours]). Fifteen patients required >200 hours (8.3 days), accounting for 69.7% of sitter costs for the surgical unit; 43.7% of costs were accounted for by patients with pre-existing cognitive impairment. CONCLUSIONS: POD is predicted by type of vascular surgery procedure, impaired cognition (MoCA), and previous delirium. Costs and morbidity related to delirium are greatest for those with impaired cognitive burden. Preoperative MoCA screening can identify those at highest risk, allowing procedure modification and informed care.

Cognitive self-assessment scales in surgical settings: Acceptability and feasibility.

Pre-existing cognitive impairment is associated with poor surgical outcomes, long hospital stays, and increased morbidity and mortality. This necessitates the use of screening tools to evaluate preoperative cognitive status in elderly surgical patients. Given the growing population of older adults and increased prevalence of cognitive impairment, it is necessary to investigate whether staff-administered or self-administered cognitive screening examinations provide more sensitive information about pre-existing (preoperative) cognitive status. Self-administered Gerocognitive Screening Examination (SAGE) was developed out of the need for a cognitive self-assessment scale in the clinic. At our institution, SAGE was given to 189 elderly surgical patients to evaluate baseline cognitive status, and preliminary results are promising that self-assessment scales are both feasible and acceptable in the surgical setting.

Psychometric properties and cross-cultural comparison of the cognitive complaints in bipolar disorder rating assessment (COBRA) in Mexican patients with bipolar disorder.

Bipolar Disorder (BD) is a serious and frequent mental health condition that is sometimes fatal. Several longitudinal studies have found an important correlation between cognition and functionality in BD. Despite the known importance of cognitive symptoms in BD, evaluation of cognitive deficits is not routinely done in clinical settings, as assessment is time-consuming and requires neuropsychological testing. The aim was to evaluate the psychometric properties of the subjective cognitive deficits in bipolar disorder (COBRA) rating scale in a Mexican sample of patients with BD and perform a cross-cultural comparison with the results obtained in other cultures. Ninety-two Healthy Subjects and 80 euthymic patients with BD were asked to complete the COBRA rating scale. The psychometric properties found in Mexican population show a good internal consistency and good discriminant validity with control subjects. Adequate congruence coefficients were obtained between the COBRA analyses in Mexican population and Spanish population and acceptable when compared to Japanese population. The COBRA scale is a brief and valid measure of cognitive complaints in BD for use in Mexican population.

A narrative review of problems with medicines use in people with dementia.

INTRODUCTION: People with dementia may be particularly susceptible to medication-related problems for various reasons. They include progressive cognitive decline, high sensitivity to the effect of medications on cognition and memory, and increased likelihood of comorbidities. AREAS COVERED: This paper aimed to review current literature on the frequency and the types of medication-related problems, and their contribution to hospital admission in people with dementia. Literature searches were conducted using key search terms of dementia and medication-related problems. Studies investigating any medication-related problems in people with dementia or cognitive impairment were included. EXPERT OPINION: Previous research showed a high prevalence of medication-related problems in people with dementia. However, no single category of medication-related problems was reported consistently as the most frequent type across studies. The available studies also showed that medication-related hospitalization was common among people with dementia. These findings underline the need for effective medication management services to reduce the risk of these problems in people with dementia and cognitive impairment. Further work is required to characterize medication-related problems comprehensively in this vulnerable patient group across settings of care. Future research should take a holistic approach in the identification of medication-related problems.

Supporting a comprehensive and coordinated evaluation of the elderly with diabetes by integrating cognitive and physical assessment in the evaluation process.

BACKGROUND: Successful ageing with diabetes is challenged by co-morbidities, which may present barriers to self-care. Currently, measurement of physical and cognitive status is not part of routine care of the older person with diabetes, and these are not taken into account when devising the treatment plan. OBJECTIVE: To describe a novel approach that integrates cognitive and physical assessment into the routine evaluation of the older person with diabetes and the tailor-made treatment plan devised accordingly. To provide estimates of the relative contribution of cognitive and physical disabilities in this population. METHODS: Cognitive and physical assessments were added to the standard evaluation. A composite measure of cognitive and of physical status categorizing each individual to intact, mild, or severe impairment was generated. In addition, all recommendations provided were categorized and tabulated. RESULTS: Of 119 individuals, over the age of 60 with type 2 diabetes who were referred because of difficulties in managing their disease, 16% and 3% of individuals met the criteria for severe cognitive/physical impairment, respectively, and 42% and 21% met the criteria for mild cognitive/physical impairment; 72%, 12.5%, 61% received recommendations related to intensification of physical activity, cognitive treatment, change in pharmacological agents, respectively. 25% were referred for further emotional treatment. CONCLUSIONS: These data suggest that a substantial proportion of individuals with diabetes over the age of 60 may have cognitive/physical impairment. It highlights the importance of measuring these as part of the multidisciplinary evaluation and being able to provide a tailor made treatment plan.

Determination of a clinically important difference and definition of a responder threshold for the UCSD performance-based skills assessment (UPSA) in patients with major depressive disorder.

BACKGROUND: This article reports an evaluation of the psychometric properties and clinically important difference (CID) threshold of the UCSD Performance-Based Skills Assessment (UPSA) in major depressive disorder (MDD), using data from a large-scale study of the effects of vortioxetine on cognitive functioning and functional capacity in MDD patients. METHODS: Adults with moderate-to-severe recurrent MDD and self-reported cognitive dysfunction were randomized to 8 weeks of double-blind treatment with vortioxetine 10/20mg QD (flexible), duloxetine 60mg QD, or placebo. Pearson correlation coefficients were calculated between UPSA composite score and demographic/disease characteristics at baseline to examine construct validity. Two methods (distribution-based and anchor-based) were used to establish a CID threshold. RESULTS: A total of 602 patients were randomized; 528 comprised the full analysis set. For the entire sample mean UPSA composite scores were 77.8 at baseline and 83.9 at week 8 (mean change, +6.1). As hypothesized, at baseline, the UPSA composite score correlated with cognitive functioning (Digit Symbol Substitution Test: r=0.36, P<0.001) and workplace productivity (Work Limitations Questionnaire: r=-0.17, P=0.008), but not depressive symptoms (Montgomery-Åsberg Depression Rating Scale: r=0.02, P=0.707) or subjective cognitive dysfunction (Perceived Deficits Questionnaire: r=-0.02, P=0.698). LIMITATIONS: Two versions of the UPSA were used and no inclusion/exclusion criteria were based on the UPSA. CONCLUSIONS: These results support the construct validity of UPSA for assessing functional capacity independent of mood symptoms. The estimated CID for changes in UPSA scores was quite consistent at +6.4 points and +6.7 based on distribution-based and anchor-based methods, respectively.
