Prevalence of dementia and major dementia subtypes in Spanish populations: A reanalysis of dementia prevalence surveys, 1990-2008

BackgroundThis study describes the prevalence of dementia and major dementia subtypes in Spanish elderly.MethodsWe identified screening surveys, both published and unpublished, in Spanish populations, which fulfilled specific quality criteria and targeted prevalence of dementia in populations aged 70 years and above. Surveys covering 13 geographically different populations were selected (prevalence period: 1990-2008). Authors of original surveys provided methodological details of their studies through a systematic questionnaire and also raw age-specific data. Prevalence data were compared using direct adjustment and logistic regression.ResultsThe reanalyzed study population (aged 70 year and above) was composed of Central and North-Eastern Spanish sub-populations obtained from 9 surveys and totaled 12,232 persons and 1,194 cases of dementia (707 of Alzheimers disease, 238 of vascular dementia). Results showed high variation in age- and sex-specific prevalence across studies. The reanalyzed prevalence of dementia was significantly higher in women; increased with age, particularly for Alzheimers disease; and displayed a significant geographical variation among men. Prevalence was lowest in surveys reporting participation below 85%, studies referred to urban-mixed populations and populations diagnosed by psychiatrists.ConclusionPrevalence of dementia and Alzheimers disease in Central and North-Eastern Spain is higher in females, increases with age, and displays considerable geographic variation that may be method-related. People suffering from dementia and Alzheimers disease in Spain may approach 600,000 and 400,000 respectively. However, existing studies may not be completely appropriate to infer prevalence of dementia and its subtypes in Spain until surveys in Southern Spain are conducted.

Dementia, stroke and Parkinson's disease in spanish populations: A review of door-to-door prevalence surveys

We identified 14 door-to-door prevalence surveys on dementia, parkinsonism or stroke in Spanish populations fulfilling specific criteria and combined selected age- and sex-specific data using logistic regression and taking Pamplona as a reference. The prevalence of dementia and of Alzheimer’s disease varied significantly with space. However, the largest variation was seen for vascular dementia: odds ratio (OR) and 95% confidence interval (CI) for Gerona were 6.42 (3.23–12.3) in women and 2.30 (1.10–4.79) in men. Stroke was particularly frequent among Arevalo’s women, with OR 2.10 and 95% CI 1.26–3.49. The prevalence of Parkinson’s disease was twofold higher in Cantalejo. Although differences in methodology make the interpretation of results problematic, the prevalence of stroke and vascular dementia in Spain seems to vary spatially, indicating a space for prevention.

Prevalence of disability in a composite ≥75 year-old population in Spain: A screening survey based on the International Classification of Functioning

BackgroundThe prevalence and predictors of functional status and disability of elderly people have been studied in several European countries including Spain. However, there has been no population-based study incorporating the International Classification of Functioning, Disability and Health (ICF) framework as the basis for assessing disability. The present study reports prevalence rates for mild, moderate, and severe/extreme disability by the domains of activities and participation of the ICF.MethodsNine populations surveyed in previous prevalence studies contributed probabilistic and geographically defined samples in June 2005. The study sample was composed of 503 subjects aged ≥75 years. We implemented a two-phase screening design using the MMSE and the World Health Organization-Disability Assessment Schedule 2nd edition (WHO-DAS II, 12 items) as cognitive and disability screening tools, respectively. Participants scoring within the positive range of the disability screening were administered the full WHO-DAS II (36 items; score range: 0-100) assessing the following areas: Understanding and communication, Getting along with people, Life activities, Getting around, Participation in society, and Self-care. Each disability area assessed by WHO-DAS II (36 items) was reported according to the ICF severity ranges (No problem, 0-4; Mild disability, 5-24; Moderate disability, 25-49; Severe/Extreme disability, 50-100).ResultsThe age-adjusted disability prevalence figures were: 39.17 ± 2.18%, 15.31 ± 1.61%, and 10.14 ± 1.35% for mild, moderate, and severe/extreme disability, respectively. Severe and extreme disability prevalence in mobility and life activities was three times higher than the average, and highest among women. Sex variations were minimal, although life activities for women of 85 years and over had more severe/extreme disability as compared to men (OR = 5.15 95% CI 3.19-8.32).ConclusionsDisability is highly prevalent among the Spanish elderly. Sex- and age-specific variations of disability are associated with particular disability domains.

Telepsychogeriatrics: a new horizon in the care of mental health problems in the elderly.

BACKGROUND The use of telemedicine for the care of mental health problems has developed significantly over the last decade thanks to the emergence of a number of stable telepsychiatry programs in many countries. Parallel to this development, this care modality has also targeted specific populations with higher difficulty in gaining access to mental health services such as the elderly. Telepsychogeriatrics is expected to have an increasing role in providing care to geographically isolated rural communities, with a particular focus on long-term care facilities, in light of the high prevalence of psychiatric disorders in these centers and the lack of available specialized care. METHODS A thorough search of the literature was conducted using Medline, Web of Science, and PsychINFO databases in order to gather available evidence on the applicability of telepsychiatry, specifically the use of videoconferencing for remote consultation, in the elderly population with mental disorders. A succinct description of the selected studies is given along with a general reflection on the state-of-the-art in the field of psychogeriatric clinical practice and research. RESULTS Research on the use of telemedicine in this age group has taken into account their special characteristics, and has focused on demonstrating its applicability, the acceptance and satisfaction of elderly users and their healthcare providers, the possibility of carrying out cognitive and diagnostic assessments, and the efficiency of these programs. CONCLUSIONS Despite limited experience, telepsychogeriatrics appears to be a viable option, well accepted by patients, including those having dementia. More systematized studies are needed in this new field based on larger sample sizes, including comparison with traditional consultations and assessment of the clinical outcomes.

Alcohol consumption in a southern European region (Galicia, Spain).

Galicia is a distinct region and an autonomous community of Spain with its own cultural identity. Two-thirds of the 2.7 million inhabitants live in the rural, reservoir of the traditional culture. Alcohol use is deeply rooted in Galician culture, and its abuse constitutes an important public health problem. Objectives. To analyze changes in alcohol consumption in the Galician adult population during the two last decades and its sociodemographic correlates, focusing on rural versus urban differences. Methods. The principal source of epidemiological information is the Galicia Study of Mental Health of Adult Population, the first household survey representative of the Galician population, in which a sample of 2510 people from the population aged 16 years and older were asked about alcohol consumption in 1985. Data from subsequent surveys are also summarized and interpreted in terms of the sociocultural evolution of Galician society. Results. The per capita annual rate of alcohol consumption in Galicia was 11,167 cc pure alcohol, 40% higher than the national average. Personal and social characteristics associated with high alcohol consumption included: males in their thirties and young females, farmers, and low socioeconomic status. The traditional rural model of drinking in which alcohol is perceived as a daily nourishment still predominates. However, an urban consumer model is quickly growing, especially among young women.

Medical, environmental and personal factors of disability in the elderly in Spain: a screening survey based on the International Classification of Functioning

OBJECTIVES The International Classification of Functioning, Disability and Health (ICF) advocates a multifactorial and multifaceted conceptualization of disability. The objective of this study was to ascertain major medical, environmental and personal determinants of severe/extreme disability among the elderly population in Spain. The assessment scheme was consistent with the ICF model of disability. METHODS Nine populations contributed probabilistic or geographically-defined samples following a two-phase screening design. The Mini-Mental State Examination and the 12-item version of the World Health Organization-Disability Assessment Schedule, 2(nd) ed. (WHO-DAS II), were used as cognitive and disability screening tools, respectively. Positively screened individuals underwent clinical work-up for dementia and were administered the 36-item version of the WHO-DAS II to estimate ICF disability levels. We used logistic regression for the purposes of data combination, adjusted for age and sex in all analyses. RESULTS The sample was composed of 503 participants aged ≥ 75 years. Alzheimeŕs disease and depression were highly predictive of severe/extreme disability (OR: 17.40, 3.71). Good access to social services was strongly associated with a low level or absence of disability (OR: 0.05 to 0.18). Very difficult access to services and having dementia or another psychiatric disorder were associated with an increase in disability (OR: 66.06). There was also a significant interaction effect between access to services and neurological disorders (OR: 12.74). CONCLUSIONS Disability is highly prevalent among the Spanish elderly and is influenced by medical, social and personal factors. Disability could potentially be reduced by ensuring access to social services, preventing dementia and stroke, and treating depression.

Care for dementia in Spain: the need for a nationwide strategy.

Spain is one of the most aged countries in the world. Of a population of 46.7 million, 7.7 million (16.7%) are 65 or older and of them, 28.45% is 80 or older. By 2050, these percentages will be 30.8% and 11.1%, respectively (IMSERSO, 2009). Although rural areas account for only one in four elderly people, population dispersion in some areas of Spain has become a problem when it comes to organising social and health care services in these very aged communities.

e-Motional Training®: Pilot study on a novel online training program on social cognition for patients with schizophrenia

Background Patients with schizophrenia have deficits in social cognition (SC), a construct that includes emotion perception (EP), social perception (SP), theory of mind (ToM) and attributive style (AS). The aim of our study was to assess the applicability, identify potential problems and obtain preliminary data on the efficacy of a new online training program on SC called e-Motional Training (ET®), which can be remotely administered and remotely supervised by a clinician. Materials and methods A pre/post intervention pilot study was conducted with 21 patients with schizophrenia in the healthcare area of Ourense, Spain (12 patients were assigned to the intervention group and 9 in the control group). The control group received standard treatment (TAU) (occupational therapy and leisure group). The intervention group received TAU plus 12 sessions (1 hour per week) with ET® (including training modules on emotional perception and a short animated cartoon for ToM and AS training, including automated metacognitive feedback). Endpoints: EP (Ekman 60 Faces Test), ToM (Hinting Task, Faux Pas, Happé), AS (Ambiguous Intentions Hostility Questionnaire). Results ET® was shown to be an understandable, viable and pleasant program for the participants. After the intervention, statistically significant data (p < 0.05) were obtained for the EP, ToM and AS variables. Conclusion ET® enables self-training in SC and online follow-up by the therapist, thereby covering the lack of online intervention instruments validated for patients with SC deficits. Our preliminary results demonstrate the feasibility of ET® and its possible efficacy in improving emotion recognition, ToM and AS.

The state of psychogeriatrics in Europe: challenges and opportunities in six European countries

With the increase in aging all over the world, and the elderly population nearly tripling from 524 million (8% of the worlds population) in 2010 to 1.5 billion (16% of the worlds population) in 2050, we will face new challenges and opportunities in providing healthcare. In 2050, it is estimated that Europe will see an increase of 70% in elderly population aged over 65 years, and 170% in those aged over 80 years (World Health Organization (WHO), 2011). It is vital to respond to the needs of this emerging population and the consequent rise in chronic diseases, especially dementia and mental health disorders, which will overload the healthcare system, as well as raise health and social costs, and demand new policies from national governments (World Health Organization, 2012). We urgently need to know how to organize healthcare for elderly people in the years to come.
