Older Individuals

Meaning

Older Individuals is a demographic classification typically defined in clinical and public health contexts as persons aged 65 years and above, a stage of life characterized by a progressive decline in physiological reserve and notable alterations in endocrine function. This cohort requires specialized clinical consideration due to the high prevalence of multimorbidity, polypharmacy, and the increased vulnerability to age-related conditions like sarcopenia, cognitive decline, and immunosenescence.
