“…This finding was confirmed by multivariate models and suggests that cognitive complaints may be part of the aging process, in agreement with the great majority of previous studies. 1, 14, 32-34 Similarly, CIND was more prevalent in older compared to younger old but there was not a clear trend with age. When directly compared with SCI, people with CIND tended to be younger.…”

We report the prevalence of subjective cognitive impairment (SCI) and cognitive impairment no dementia (CIND), their socio-demographic profile, and the contribution of genetic background and shared familial environment to SCI and CIND. Subjects were 11,926 dementia-free twin individuals aged ≥ 65 from the Swedish Twin Registry. SCI was defined as subjective complaint of cognitive change without objective cognitive impairment and CIND was defined according to current criteria. Overall prevalence of SCI and CIND was 39% (95% CI 38-39) and 25% (95% CI 24-25). Among those with CIND, 57% had subjective cognitive complaints; 43% did not. In multivariate GEE models, both SCI and CIND were older compared with people without any cognitive impairment. CIND were also less educated, more likely to be unmarried and to have lower socioeconomic status (SES). SCI individuals differed from persons with CIND as they were older, more educated, more likely to be married, and to have higher SES. Co-twin control analysis, which corrects for common genetic and shared environmental background, confirmed that low education was still associated with CIND. Probandwise concordance for SCI and CIND was 63% and 52% in monozygotic twins, 63% and 50% in dizygotic same-sex twins, and 42% and 29% in dizygotic unlike-sex twins. Tetrachoric correlations showed no significant differences between monozygotic and dizygotic same-sex twins. We conclude that subjective and objective cognitive impairment are both highly prevalent among nondemented elderly yet have distinct sociodemographic profiles. Shared environmental influences rather than genetic background play a role in the occurrence of SCI and CIND.

“…SMC were reported by 57.3% of participants. SMCs were correlated with advanced age and female sex (Park et al, 2007). In fact many other studies have noted a strong relationship with age with more than 40% of those aged 65-74 years, rising to almost 90% of those over 85 years reporting SMC in one study (Glenn et al, 1994).…”

When assessed by simple questions, SMC appear to be present in the minority of those with mild cognitive impairment and dementia. In cross-sectional community settings, even when people agree that they have SMC there is only a 20% or 30% chance that dementia or MCI are present, respectively. Despite this, the absence of SMC may be a reasonable method of excluding dementia and MCI and could be incorporated into short screening programs for dementia and MCI but replication is required in clinical settings.
