TL;DR: To review studies that have reported on the prevalence of memory complaints and the relationship betweenMemory complaints and impairment or decline (dementia) in elderly individuals is reviewed.

TL;DR: Age- and gender-specific estimates of the prevalence of dementia in Europe and differences in prevalence across countries were pooled and re-analysed original data of prevalence studies of dementia carried out in some European countries between 1980 and 1990.

TL;DR: The findings of this study suggest that memory complaints are a relatively strong predictor of incident Alzheimer's disease in older persons in whom cognitive impairment is not yet apparent, and suggest that older persons may be aware of a decline in cognition at a time when mental status tests are still unable to detect a decline from premorbid functioning.

TL;DR: Feeling lonely rather than being alone is associated with an increased risk of clinical dementia in later life and can be considered a major risk factor that, independently of vascular disease, depression and other confounding factors, deserves clinical attention.

TL;DR: In this paper, the authors reanalyzed and compared current prevalence estimates of Alzheimer's disease in Europe and found that prevalence increased exponentially with advancing age and, in some populations, was consistently higher in women.
