“…As regards the major dementia subtypes, the results confirmed what is being found by other studies: that AD is the most frequent subtype in older adults, followed by VD [35,36,37]. AD was diagnosed in 63.7% of the cases, a result similar to those obtained by other studies that have shown AD to affect more than 50% of cases of individuals aged 65 or more years [6,28], and more than 60% among still older age groups [38,39].…”

Aims: To describe the overall prevalence of dementia syndrome and its major subtypes among elderly clients of a private health care plan and to ascertain the association between this syndrome and socioeconomic characteristics. Methods: A survey was organized in two stages: screening for cognitive impairment and diagnostic evaluation. The study population comprised 683 elderly subjects (aged >67 years), an expanded sample of 7,486 individuals, of the database of the FIBRA-RJ, which evaluated clients of a private health care plan residing in northern districts of the municipality of Rio de Janeiro, Brazil. The diagnosis of dementia was obtained according to DSM-IV criteria. Results: A total of 115 individuals were diagnosed with dementia, resulting in a prevalence of 16.9% (95% CI = 14.4–19.8). The association was strongest among older age groups, i.e. 85–89 years old (prevalence ratio = 8.85; 95% CI = 2.11–37.11) and 90 or more years old (prevalence ratio = 8.85; 95% CI = 2.11–37.11), and among illiterate people (prevalence ratio = 2.77; 95% CI = 1.07–7.19). Sex, personal income and marital status displayed no association with dementia. Conclusion: The prevalence of dementia was higher than found by population-based studies. These findings point to a possibility of a high demand for specialized services among older adults served by the private health care sector.

“…Data showed that incidence [10,12,13,18,32,34,39,42,43,49], prevalence [16,27,30,36,46], and mortality rates [25] of AD increased with age (Tables 3-5). In all studies assessing incidence [13,18,26,39,43], prevalence [16,27,30,38,43,46], or mortality rates [21,24] by gender, AD, and mortality due to AD were more common in females (regardless of their age) compared to males. For the incidence of AD, the ratio of females:males was approximately the same in all of the studies, with the incidence of AD in women being approximately twice that observed in males of a comparable age.…”

“…In a multi-center study with eight European countries, including Spain and Sweden, the incidence and prevalence of different dementia diagnoses, particularly of vascular dementia, differed greatly between countries [11, 12]. However, another study did not find differences in the odds of dementia between a composite of Spanish studies and the Kungsholmen study, in Sweden [14]. Prevalence variations are apparent even within countries, for example, in Spain, age- and sex-adjusted prevalence for dementias for +70 populations ranged between 3% and 12% depending on the geographical area [13, 15].…”

The aim of this study was to compare the frequency of dementia diagnoses from two dementia registries in Europe. Patients registered between 2007 and 2013 in the Swedish Dementia Registry (SveDem; Sweden) and in the Registry of Dementias of Girona (ReDeGi; North-East of Spain) were selected. We compared sociodemographic data, Mini-Mental State Examination (MMSE) scores, dementia subtype, and medication consumption of 22,384 cases from SveDem and 5,032 cases from ReDeGi. The average age (78.1 years SveDem versus 79.7 years ReDeGi) and the gender (female 58.2% SveDem versus 61.5% ReDeGi) did not greatly differ. MMSE score at diagnosis was higher for SveDem cases (22.1 versus 17.8). Alzheimer’s disease (AD) accounted for the main dementia subtype (36.6% SveDem versus 55.6% ReDeGi). The proportion of vascular dementia (VaD) and mixed dementia was higher in SveDem (18.8% versus 6.4% and 24.9 versus 13.4%), with an odds ratio (OR) and 95% confidence interval (CI) for SveDem relative to the ReDeGi of 3.41 (3.03–3.84) for VaD, and 2.15 (1.97–2.35) for mixed dementia. This was at the expense of a lower frequency of AD in SveDem (OR 0.41; 95% CI 0.39–0.44). Other dementia diagnoses such as frontotemporal dementia or dementia with Lewy bodies did not significantly differ between registries (2.3% versus 2.9%; 1.9 versus 3.1%). Large differences in medication consumption at the time of dementia diagnosis were detected (4.7 treatments SveDem versus 6.8 ReDeGi). Northern and southern European dementia cohorts differ in demographic characteristics, MMSE score at diagnosis, and drug treatment profile.

Prevalence and European comparison of dementia in a ≥75-year-old composite population in Spain

Abstract: Dementia prevalence in Spain is comparable to other European populations, while a high number of undiagnosed cases live in the community. The potential impact of Mediterranean diet, hypertension control and decreasing vascular risk factors is discussed.
