“…A total of 3,427 records were identified, out of which nine were selected for inclusion on the prescreening and the application of the predefined inclusion criteria [28–36]. Two articles were further excluded as they did not use the DSM IV criteria [28, 32], and four because data were not report separately for age classes and sex [31, 34–36], thus leaving only three studies were included among the 3,427 records identified [29, 30, 33].…”

Background:Dementia, including Alzheimer’s disease (AD), is one of the most burdensome medical conditions. Usually, the reviews that aim at calculating the prevalence of dementia include estimates from studies without assessing their methodological quality. Alzheimer’s Disease International (ADI) proposed a score to assess the methodological quality of population-based studies aimed at estimating the prevalence of dementia. During the last three years, the European Commission has funded three projects (Eurodem, EuroCoDe, and ALCOVE) in order to estimate the prevalence of dementia in Europe.Objective:The aim of this study was to perform a systematic review and meta-analysis of data on the prevalence of dementia in Europe derived from studies that included only subjects with a diagnosis of dementia according to the DSM IV criteria, and that had a high quality score according to ADI criteria.Methods:We considered the studies selected by the two projects EuroCoDe (1993–2007) and Alcove (2008–2011), and we performed a new bibliographic search. For the systematic review, we only selected the subset of articles that included subjects with a diagnosis of dementia according to the DSM IV criteria. The studies were qualitatively assessed using the ADI tool.Results:The meta-analysis considered 9 studies that were carried out in Europe between 1993 and 2018 including a total of 18,263 participants, of which 2,137 were diagnosed with dementia. The prevalence rate standardized for age and sex resulted 7.1%.Discussion:This is the first systematic review on the prevalence of dementia in Europe considering only high-quality studies adopting the same diagnostic criteria (i.e., DSM IV).

“…In Bulgaria, MCI prevalence was found to be 6.7%. Totally 607 subjects over 65 years old, a sample very similar to ours, were included; MCI diagnosis was made according to Petersen criteria, modified by Portet et al [23] In Italy, MCI prevalence was 6% among a sample of 6921 subjects assessed using an operational definition according to MMSE score, but much higher almost 24.5% when psychometrically derived criteria of MCI were used [24]. On the contrary, in northern Israel, a high prevalence of MCI, 32.1%, was observed among 944 participants [25].…”

There are no data available on the prevalence of Mild Cognitive Impairment (MCI) in Greece, and the existing information about dementia shows important variations depending on the geographical setting as well as the methodology employed. The aim of this study was to determine the prevalence of MCI in individuals aged over 65 in a rural area in the north part of Greece. From 1428 residents, 678 were finally examined, with a mean age of 73.35 years. Assessments, including neuropsychological testing, neurological examination and medical history, were used to assign a diagnosis of normal cognition, mild cognitive impairment (MCI), with or without depression, depression or dementia according to suitable criteria. A questionnaire was also used to obtain social and demographic data. The 26.3% were classified as Mild Cognitive Impaired without depression, the 8.8% as Mild Cognitive Impaired due to depression, 5.9% had sole depression, the 2.4% were diagnosed with dementia and 56.6% had normal mental status. The observed prevalence for MCI with and without depression implies a total of 35.1% of all people aged over 65 with MCI in the study area. Mild cognitive impairment is more prevalent in Greece than dementia, and its subtypes vary in prevalence.

“…Two were excluded as ineligible -one because only estimates of Alzheimer's disease prevalence were provided (Afgin et al, 2012), and one because prevalence estimates were derived from survivors from previous prevalence surveys ( Virues-Ortega et al, 2011). Six of the 14 remaining eligible studies could not be included in the meta-analysis, since age-specific prevalence estimates were not provided, or only single-age groups were studied (Spada et al, 2009;Scafato et al, 2010;Dimitrov et al, 2012;De Deyn et al, 2011;Mathillas et al, 2011;Adelman et al, 2011). Thus, eight additional studies (four from Spain, two from Italy, and one each from Portugal and the UK) could be included in the updated meta-analysis (Table 3.…”

Prevalence of Dementia and Mild Cognitive Impairment in a Bulgarian Urban Population

Abstract: Our results support the hypothesis that prevalence of vascular cognitive impairment may be higher in Bulgaria than in most European countries.
