Association between frailty and dementia: a population-based study
Kulmala J, Nykänen I, Mänty M, Hartikainen S.. Gerontology, 2013-08-17
Topic: Risk, prevention and care in population studies
Background Frailty is commonly considered as a syndrome with several symptoms, including weight loss, exhaustion, weakness, slow walking speed and physical inactivity. It has been suggested that cognitive impairment should be included in the frailty index, however the association between frailty and cognition has not yet been fully established. Objective To investigate cross-sectionally whether frailty is associated with cognitive impairment or clinically diagnosed dementia in older people.
Key findings
- It has been suggested that cognitive impairment should be included in the frailty index, however the association between frailty and cognition has not yet been fully established.
- Objective To investigate cross-sectionally whether frailty is associated with cognitive impairment or clinically diagnosed dementia in older people.
- Methods The study included a total of 654 persons aged 76-100 years (mean 82 ± 4.6).
- Frailty status of the participants was assessed using the Cardiovascular Health Study criteria.
Why it matters
This population-based study of 654 people aged 76 to 100 examined whether frailty was associated with cognitive impairment or diagnosed dementia at one point in time. It is a cross-sectional association study and does not test any treatment, cure, or prevention.
