“…Similar results have been found in developed countries, 5,20 although in those countries the association did not remain signifi cant after adjusting for confounding variables. Elderly people with cognitive impairment more frequently present chronic health problems 28 and functional limitations, 20 and thus it is plausible to expect a higher frequency of polypharmacy among them.…”

“…Similar results have been found in developed countries, 5,20 although in those countries the association did not remain signifi cant after adjusting for confounding variables. Elderly people with cognitive impairment more frequently present chronic health problems 28 and functional limitations, 20 and thus it is plausible to expect a higher frequency of polypharmacy among them. Hanlon et al 5 (1996) expressed concern that lower consumption of medications among elderly people with cognitive impairment might constitute underuse of medications, because doctors had failed to prescribe adequate drug therapy, infl uenced by knowledge of their patients' cognitive status.…”

“…Hidalgo et al 7 (1997) and Klarin et al 9 (2003) found among elderly people in Spain and Sweden respectively that a greater number of medications was consumed among those with cognitive impairment, but the associations did not remain signifi cant after adjustment for other variables. On the other hand, among elderly people in Britain 20 and the United States, 5 the consumption of medications was lower among those who presented cognitive impairment. However, like in the studies cited earlier, the differences did not remain signifi cant after adjustment for the other exploratory variables.…”

“…Cognitive impairment is frequent in old age, 20 and it may have negative repercussions on elderly peoples' functional capacity. 26 Individual characteristics, lifestyle habits, diseases and illnesses are factors that predispose elderly people to such impairment, but it may be exacerbated through the use of medications.…”

Prevalence of cognitive impairment and related risk factors incommunity-dwelling elderly in Kayseri, Turkey

“…The burden of CImp is correlated with increased age (2). Prevalence of cognitive dysfunction rises with age, affecting 20% of those aged 65 years and 45% of those aged 90 years and older, with a doubling of prevalence every 5 years (3,4). CImp is not only a significant problem for mental but also for physical deficiency of the elderly, negatively impacting factors such as nutrition and self-care (5).…”
