Fisiología del envejecimiento: Actualización y perspectiva genética

Aging is a physiological process resulting from the accumulation of molecular and cellular damage over time, leading to a gradual decline in overall physical and mental health. Throughout this temporal continuum, various physiological alterations occur in the organism, modifying the individual's response to multiple stimuli and adverse factors. At the same time, an increasingly significant manifestation of genetic modifications is observed, which are intrinsically interconnected with the dynamics of these adaptive processes. The geriatric population is characterized by its high prevalence in hospital settings, particularly in critical care units, where admissions from this group account for nearly 50% of total admissions. Thus, acquiring and updating knowledge is relevant and necessary to ensure a more effective therapeutic approach for geriatric patients.
