Definition of frailty
There is no universally accepted definition of frailty:
- Depends on whether we consider populations, individuals, research, clinical
levels.
What is agreed by most:
- A geriatric syndrome: multifactorial
- cumulative declines and decreased reserves in multiple physiological and
- rgan systems: homeostenosis.
- physiologic dysregulation involves multi-organ systems including the
musculoskeletal, immune, endocrine, hematologic, and cardiovascular systems: the sum is more important than the nature of each
- Results in vulnerability to adverse outcomes: e.g. Falls, death, dependence
- Triggered or revealed by minor stressor events, stimuli
- Age plays the major role: prevalence with age

- The most used criteria to characterize the phenotype of frailty as
clinical syndrome are:* : – Loss of wait: self reported – Weakness: grip strength – Exhaustion: self reported – Slowed walking speed: measure of walk speed – Low physical activity: self reported Frailty : presence of at least 3 of these 5 characteristics

Operationalization/Diagnosis of frailty
The cumulative frailty index (accumulation of deficits):*
- disability,
- diseases,
- physical and cognitive impairments,
- psychosocial risk factors, and
- Geriatric syndromes (eg, falls, delirium, and urinary incontinence)

ASSOCIATED to atherosclerosis, osteoporosis, sarcopenia to functional decline and all cause mortality PREDICTING steeper functional decline during a follow up of 3.5 years (Ferucci et al, JAGS, 2002, 50:1941) measured by: decreased muscle strength and power and slowed walking speed two central components of the frailty syndrome. In Vitro: PBMC stimulated by LPS produced higher IL-6 in frail than Non-frail community dwelling subjects
IL-6 levels: independently associated with frailty

Conclusion Frailty may be the expression of a THRESHOLD when the physiological reserve is critically decreased by aging aging+ syndr Frailty is more the result of the SUM of altered systems than abnormalities in a particular system: IMMUNE + ENDOCRINE+ MUSCLE + NEURONAL Frailty can be an expression of the BIOLOGICAL age rather than the chronological age, however causal relationships between IL-6, TNF-alpha and
- ther inflammatory markers and frailty have yet to be proven
No biological markers can currently be associated directly to frailty No nutritional interventions by Antioxydants OR Vitamins are efficient BUT Mediterranean diet could be
