    [Show abstract] [Hide abstract] ABSTRACT: Background: The concept of dependence has been proposed as an integrative measure to assess the progression of Alzheimer's disease (AD).This study aimed to investigate the association of patient's dependence level with the caregiver burden within a general theoretical model that includes other well-established determinants. Methods: Observational and cross-sectional multicenter study. The sample consisted of patients with AD recruited in outpatient consultation offices by a convenience sampling procedure stratified by dementia severity. Cognitive and functional status, behavioral disturbances, dependence level, medical comorbidities, and caregiver burden were assessed by using standardized instruments. A path analysis was used to test the hypothesized relationships between the caregiver burden and its determinants, including the level of dependence. Results: The sample consisted of 306 patients (33.3% mild, 35.9% moderate, 30.7% severe), the mean age was 78.5 years (SD = 7.8), and 66.2% were women. The model fit was acceptable and explained 29% of the caregiver burden variance. Primary stressors were the level of dependence and the distress related to behavioral disturbances. Caregiver's age, gender, and co-residence with the patient were the contextual factors related to caregiver burden. The job status of the caregiver was a significant secondary stressor, functional disability was indirectly associated with caregiver burden via dependence, and frequency of behavioral disturbances was indirectly associated with the caregiver burden via distress. Conclusions: Dependence was, apart from behavioral disturbances, the most important primary stressor directly related to caregiver burden irrespective of the disease severity.

    [Show abstract] [Hide abstract] ABSTRACT: Introduction: Brief cognitive tests (BCT) may help detect cognitive impairment (CI) in the clinical setting. Several BCT have been developed and/or validated in our country, but we lack specific recommendations for use. Development: Review of studies on the diagnostic accuracy of BCT for CI, using studies conducted in Spain with BCT which take less than 20min. We provide recommendations of use based on expert consensus and established on the basis of BCT characteristics and study results. Conclusion: The Fototest, the Memory Impairment Screen (MIS) and the Mini-Mental State Examination (MMSE) are the preferred options in primary care; other BCT (Clock Drawing Test [CDT], test of verbal fluency [TVF]) may also be administered in cases of negative results with persistent suspected CI or concern (stepwise approach). In the specialised care setting, a systematic assessment of the different cognitive domains should be conducted using the Montreal Cognitive Assessment, the MMSE, the Rowland Universal Dementia Assessment, the Addenbrooke's Cognitive Examination, or by means of a stepwise or combined approach involving more simple tests (CDT, TVF, Fototest, MIS, Memory Alteration Test, Eurotest). Associating an informant questionnaire (IQ) with the BCT is superior to the BCT alone for the detection of CI. The choice of instruments will depend on the patient's characteristics, the clinician's experience, and available time. The BCT and IQ must reinforce - but never substitute - clinical judgment, patient-doctor communication, and inter-professional dialogue.

    [Show abstract] [Hide abstract] ABSTRACT: Background The longitudinal association of depression and pain according to gender was investigated using a population-based sample from 13 European countries. Methods The study population was taken from waves 4-5 of the Survey of Health, Ageing and Retirement in Europe. The sample consisted of 22,280 participants ≥50 years, who were interviewed at baseline, and after two years. Regression models for each gender were used to assess the variables associated with depression and pain incidence and persistence. Results Prevalences of depression, pain, and depression-pain co-occurrence, were higher in women than in men (depression: 34.5% vs. 20.3%; OR=2.1; 95% CI=1.9-2.2; pain: 60.2% vs. 53.5%; OR=1.3; 95% CI=1.2-1.4; co-occurrence 25.3% vs. 14.0%; OR=2.3; 95% CI=2.2-2.6). Treated baseline pain in women (OR=1.6; 95% CI=1.3-2.0), and treated/untreated pain in men (untreated OR=1.3; 95% CI=1.1-1.7; treated OR=2.0; 95% CI=1.5-2.7), were associated with incident depression. Untreated baseline depression was associated with incident pain (women OR=1.3; 95% CI=1.1-1.7; men OR=1.8; 95% CI=1.3-2.6), and with persistent pain only in women (OR=1.3; 95% CI=1.1-1.6). Limitations We lack information on pain severity, and the consumption of analgesics was used as a proxy. We lack information on antidepressants and anxiolytics consumption separately. Participants were interviewed twice in two years, and pain/depression at both interviews were considered persistent although they may have relapsed and recurred. Conclusions Treated baseline pain is a risk factor for incident depression in both genders; untreated baseline pain is a risk factor only in men. Treating depression at baseline may protect from developing pain in both genders, and in women, it may also protect from pain persistence.

  • [Show abstract] [Hide abstract] ABSTRACT: The Trail Making Test (TMT) is used as an indicator of visual scanning, graphomotor speed, and executive function. The aim of this study was to examine the TMT relationships with several neuropsychological measures and to provide normative data in community-dwelling participants of 55 years and older. A population-based Spanish-speaking sample of 2,564 participants was used. The TMT, Symbol Digit Test, Stroop Color-Word Test, Digit Span Test, Verbal Fluency tests, and the MacQuarrie Test for Mechanical Ability tapping subtest were administered. Exploratory factor analyses and regression lineal models were used. Normative data for the TMT scores were obtained. A total of 1,923 participants (76.3%) participated, 52.4% were women, and the mean age was 66.5 years (Digit Span = 8.0). The Symbol Digit Test, MacQuarrie Test for Mechanical Ability tapping subtest, Stroop Color-Word Test, and Digit Span Test scores were associated in the performance of most TMT scores, but the contribution of each measure was different depending on the TMT score. Normative tables according to significant factors such as age, education level, and sex were created. Measures of visual scanning, graphomotor speed, and visuomotor processing speed were more related to the performance of the TMT-A score, while working memory and inhibition control were mainly associated with the TMT-B and derived TMT scores. © The Author(s) 2015.

    [Show abstract] [Hide abstract] ABSTRACT: Los cuestionarios al informador, en sentido estricto, están pensados para ser administrados a un informador, habitualmente el cuidador principal, y tienen como finalidad más inmediata la evaluación cognitiva de los pacientes con deterioro cognitivo y/o demencia. Suelen ser breves e incluyen preguntas sobre las capacidades cognitivas y funcionales del estado actual, en relación a su situación previa. Pueden ser utilizados como instrumento de cribado o complementarios a la evaluación clínica. Como ejemplo de ellos estarían el Blessed Dementia Scale (BDRS)1, el Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE)2 y el Ascertain Disease-8 (AD8)3. Un segundo grupo de instrumentos son aquellos que, aplicados directamente al paciente, permiten un análisis del estado global del paciente, aunque incluyen una parte específica dirigida al informador. El Clinical Dementia Rating (CDR)4 y el General Practitioner Assessment of Cognition (GPCOC)5 serían ejemplos de este tipo de cuestionarios. Existe un tercer grupo de instrumentos, también para ser administrados al informador, que tienen como objetivo proporcionar información acerca de algún aspecto específico de la situación del paciente: capacidades funcionales, síntomas psicológicos y conductuales, dependencia, etc. En este grupo se encontrarán cuestionarios como el Functional Activities Questionnaire (FAQ)6 o el Neuropsychiatric Inventory (NPI)7. Los motivos para la elaboración de los cuestionarios específicos al informador son varios, el más importante se refiere a la dificultad que puede presentar la evaluación del paciente en algunos casos: incapacidad, enfermedad, negativa a la evaluación, anosognosia, etc. Así mismo ayudan a obtener información sistemática con pruebas más simples y de fácil aplicación para la detección del deterioro cognitivo, siendo especialmente útiles en la atención Primaria. La mayoría de los instrumentos de este tipo obtienen unos valores de sensibilidad y especificidad superiores a los logrados con el Mini Mental State Examination (MMSE) en la detección del deterioro cognitivo. Jorm (1996)8 plantea varias ventajas de los cuestionarios: el conocimiento diario del informador, el no requerir la presencia del paciente, la aplicación en pacientes no testables, la facilidad para responder por teléfono o por e-mail y la perspectiva longitudinal que puede aportar el informador. Por el contrario el inconveniente principal de los cuestionarios al informador es el de poder acceder a un informador fiable, o bien que en algunos informadores pueden producirse valoraciones sesgadas.

    [Show abstract] [Hide abstract] ABSTRACT: Drug spending increases exponentially from the age of 65-70 years, and dementia is one of the diseases significantly contributing to this increase. Our aim was to describe pharmaceutical consumption and cost in patients with dementia, using the Anatomical Therapeutic Chemical (ATC) classification system. We also assessed the evolution of costs and consumption, and the variables associated to this evolution during three years. Three years prospective cohort study using data from the ReDeGi and the Health Region of Girona (HRG) Pharmacy Unit database from the Public Catalan Healthcare Service (PCHS). Frequency of consumption and costs of ATC categories of drugs were calculated. Sample of 869 patients with dementia, most of them with a diagnosis of degenerative dementia (72.6%), and in a mild stage of the disease (68.2%). Central nervous system (CNS) drugs had the highest consumption rate (97.2%), followed by metabolic system drugs (80.1%), and cardiovascular system drugs (75.4%). Total pharmaceutical cost was of 2124.8 € per patient/year (standard deviation (SD)=1018.5 €), and spending on CNS drugs was 55.5% of the total cost. After 36 months, pharmaceutical cost increased in 694.9 € (SD=1741.9), which was associated with dementia severity and institutionalization at baseline. Pharmaceutical consumption and costs are high in patients with dementia, and they increase with time, showing an association with baseline dementia severity and institutionalization. CNS drugs are the pharmaceuticals with highest prescription rates and associated costs. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  • [Show abstract] [Hide abstract] ABSTRACT: The objective of this cross-sectional and multicenter study was to evaluate the psychometric properties of the Spanish version of the Dependence Scale (DS) and to assess the relationship between dependence and clinical measures according to disease severity. Medical comorbidities, cognitive status and functional status, behavior, dependence, caregiver burden, and medical and social resources were assessed using standardized instruments. The sample consisted of 343 patients (32.1% mild, 36.7% moderate, and 31.2% severe), the mean age was 78.9 years (standard deviation = 7.4), and 67.0% were women. Criterion and construct validity index of DS were appropriate. The DS standard error of measurement was ±1.23. The explained variance in DS ranged between 0.598 and 0.731, and the relative contribution of clinical measures depended on disease severity. Current findings confirm that the Spanish version of the DS has appropriate psychometric indices and suggest that clinical indicators have different contribution to dependence according to disease severity.

    [Show abstract] [Hide abstract] ABSTRACT: Background: There is a lack of information regarding geographical differences in the incidence and prevalence of dementia diagnosis according to the degree of aging of the population. The objectives of this study were to analyze the rate of dementia diagnoses, and to compare the dementia subtypes and the clinical characteristics of the patients depending on the degree of aging of their municipalities. Methods: We used data from the Registry of Dementias of Girona (ReDeGi), containing the cases of dementia diagnosed in the memory clinics of the Health Region of Girona, in Catalonia (Spain), during 2007-2012. The municipalities were classified by a cluster analysis as aged or young municipalities according to their proportion of older people using population ageing indicators. The incidence rates of dementia diagnosis in each type of municipality were compared. Results: The ReDeGi registered 4,314 cases in the municipalities under surveillance. The clinical incidence of dementia was lower in aged municipalities (4.5 vs. 6.1 cases per 1,000 person-years aged 65 and over). Patients from young municipalities had an increased frequency of behavioral and psychological symptoms of dementia. Conclusions: The environment may influence the clinical manifestations of dementia that predispose people to visit health specialists and obtain a diagnosis.

    [Show abstract] [Hide abstract] ABSTRACT: Background and objective: The presence of anosognosia is a disorder that affects the clinical presentation of Alzheimer's disease (AD), increasing in frequency with the evolution of AD. The objective was to determine the prevalence of anosognosia and analyze the associated factors and predictors. Patient and Method: Multicenter transversal and observational study of 345 AD patients. Anosognosia was assessed by Anosognosia Questionnaire in Dementia (AQ-D) and the evolutionary stage with the Global Deterioration Scale (GDS). Tests were used MMSE, DAD and NPI to assess cognition, functional status and neuropsychiatric symptoms, respectively. We adjusted linear regression models to determine the associated variables and binary logistic regression (RLog) to identify predictors of anosognosia. Results: The overall prevalence of anosognosia was 46.7% (confidence interval 95% [95% CI] 41.3 to 52.1). The prevalence in stages was 28.4% (GDS 4), 64.6% (GDS 5) and 91.4% (GDS 6). The RLog identified as predictors older age (odds ratio [OR] 1.04; IC 95% 1.01-1.09), lower functional capacity (OR 0.96; IC 95% 0.93-0.98), lower cognitive level (OR 0.9; IC 95% 0.88-0.99), and greater apathy (OR 1.1; IC 95% 1.03-1.18), disinhibition (OR 1.2; IC 95% 1.09-1.50), irritability (OR 1.1; IC 95% 1.09-1.50) and motor disorders (OR 1.2; IC 95% 1.09-1.50). Conclusions: Anosognosia increases with further deterioration. In patients undergoing mild predictor variables were apathy, disinhibition and motor disorders.

    [Show abstract] [Hide abstract] ABSTRACT: Although numerous studies have examined caregiver burden in the context of Alzheimer’s disease, discrepancies remain regarding the influence of certain factors. This study aimed to identify trajectories of caregiver burden in the context of Alzheimer’s disease, as well as the factors associated with them. A cohort of patients and caregivers (n = 330) was followed up over three years. Growth mixture models were fitted to identify trajectories of caregiver burden according to scores on the Zarit Burden Interview (ZBI). A multilevel multinomial regression analysis was then conducted with the resulting groups and the patient and caregiver factors. In the sample as a whole, burden increased during follow-up (F = 4.4, p = 0.004). Three groups were identified: G1 (initially high but decreasing burden), G2 (moderate but increasing burden), and G3 (low burden that increased slightly). Patients in G1 and G2 presented more neuropsychiatric symptoms and poorer functional status than did those in G3. Caregivers in G1 and G2 had poorer mental health. Spouses and, especially, adult children who lived with their parent (the patient) were more likely to belong to G2 (odds ratio [OR] 6.24; 95% CI 2.89–13.47), as were sole caregivers (OR 3.51; 95% CI 1.98–6.21). The patient factors associated with increased burden are neuropsychiatric symptoms and functional status, while among caregivers, being the sole carer, poor mental health, and living with the patient are of relevance.

    [Show abstract] [Hide abstract] ABSTRACT: The objective of this cross-sectional study was to validate an abridged version of the Anosognosia Questionnaire—dementia (AQ-D) for screening anosognosia in daily practice. The authors reduce the AQ-D from 30 items to 9, with a large simple (n = 352) of patients with Alzheimer disease (AD). The Cronbach a was .793 and an area under the receiver–operating characteristic curve was 0.946. The k index between new abridged AQ-D (AAQ) and original AQ-D was .800. The AAQ presents good validity and reliability indicators and kept concordance with the original scale. It is quick and easy to administer and it can simplify the clinical screening of anosognosia in patients with AD.

    [Show abstract] [Hide abstract] ABSTRACT: Psychotropic drugs are usually prescribed to deal with behavioral and psychological symptoms of dementia, especially when nonpharmacologic approaches are not available or have limited efficacy. Poor outcomes and serious adverse events of the drugs used must be addressed, and risk-benefit ratios need to be considered. The aim of this longitudinal study was to describe the evolution of dispensation of psychotropic drugs in patients with Alzheimer's disease (AD) and to identify the associated demographic and clinical variables. Longitudinal study using 698 cases with AD included in the Registry of Dementias of Girona in 2007 and 2008 and followed up during 3 years. Drugs were categorized according to the Anatomical Therapeutic Chemical classification. Binary logistic regression analyses were used to detect the variables associated with the use of antipsychotics, selective serotonin reuptake inhibitors (SSRIs), anxiolytics, and hypnotics. Of the patients, 51.2% consumed antipsychotics at least once during the three years of the study, whereas 73.3% and 58.2% consumed SSRIs and anxiolytics, respectively; 32.8% used hypnotics. Antipsychotic use was associated with a diagnosis of AD with delusions) [odds ratio (OR) = 5.7] and with increased behavior disorders (OR = 1.2). Patients with AD with depressed mood were more likely to be treated with SSRIs (OR = 3.1), while being a woman was associated with increased dispensation of anxiolytics (OR = 1.9) and SSRIs (OR = 2.2). Consumption of psychotropic drugs by the patients with AD registered in the Registry of Dementias of Girona is very high. Despite all the described adverse effects and recommendations of caution in their use, antipsychotics still are extensively used.
