The assessment of cognitive impairment suspected of dementia in Polish elderly people: results of the population-based PolSenior Study

The Prevalence of Cognitive Impairment among Older Adults in Jamaica

“…Other studies using the cut-point of 23/24 documented lower cognitive impairment prevalence of 17.0% in Korea (36), 18.3% in the United Kingdom (37) and 20.4% in Poland (38). In a Brazilian population of similar age and educational attainment as Jamaica, using a cut-point of 22/23, the prevalence of cognitive impairment was 34.0% (39).…”

Environment and cognitive aging: A cross-sectional study of place of residence and cognitive performance in the Irish longitudinal study on aging.

“…Despite the plausibility of the association between physical aspects of the environment and cognition, this topic is understudied (Dunwoody, 2006), possibly due to methodological difficulties (Wu, Prina, & Brayne, 2014). Nonetheless, epidemiological studies report geographical variations in dementia and cognitive impairment (Bae et al, 2015;Cahill, O'Shea, & Pierce, 2012;Contador, Bermejo-Pareja, Puertas-Martin, & Benito-Leon, 2015;Gavrila et al, 2009;Iyer et al, 2014;Klich-Rączka et al, 2014;Nunes et al, 2010;Russ, Batty, Hearnshaw, Fenton, & Starr, 2012), with better cognitive performance for older urban than rural dwellers, suggesting that urban environments may be more stimulating either cognitively, socially or in relation to lifestyle. Robertson (2013Robertson ( , 2014 for example, linked novelty in the environment (more likely to be found in urban environments) with enhanced cognitive reserve through the activation of the noradrenergic brain system.…”

Dementia as a contemporary challenge for providing care for the aging populations

“…In the PolSenior study, dementia-related cognitive dysfunction increased from 9.5% in the 65-69 age group, to 10.1% in the 70-74 age group, 14.5% in the 75-79 age group, 15.6% in the 80-84 age group, and 20.9% in the 85-89 age group. In the oldest group (aged 90 and above) cognitive dementia-indicating disorders were found in 34.4% of respondents [10].…”
