Chronological age is not an accurate predictor of morbidity and mortality risk, as individuals' aging processes are diverse. Phenotypic age acceleration (PhenoAgeAccel) is a validated biological age measure incorporating chronological age and biomarkers from blood samples commonly used in clinical practice that can better reflect aging-related morbidity and mortality risk. The heterogeneity of age-related decline is not random, as environmental exposures can promote or impede healthy aging.

Frailty is a syndrome that can inform clinical treatments and interventions for older adults. Although implementation of frailty across medical subspecialties has the potential to improve care for the aging population, its uptake has been heterogenous. While frailty assessment is highly integrated into certain medical subspecialties, other subspecialties have only recently begun to consider frailty in the context of patient care.

Inflammaging, a state of chronic, progressive low-grade inflammation during aging, is associated with several adverse clinical outcomes, including frailty, disability, and death. Chronic inflammation is a hallmark of aging and is linked to the pathogenesis of many aging-related diseases. Anti-inflammatory therapies are also increasingly being studied as potential anti-aging treatments, and clinical trials have shown benefits in selected aging-related diseases.

Article Synopsis
  • - Inflammation plays a critical role in age-related diseases, particularly neurological conditions like Alzheimer's Disease and other neurodegenerative disorders, significantly impacting healthcare as the population ages.
  • - The research highlights that targeting inflammation may mitigate Abeta proteotoxicity, with drugs like Humira demonstrating the commercial potential of anti-inflammatory treatments.
  • - High-throughput screenings identified compounds such as phenylbutyrate, methicillin, and quetiapine as effective at reducing Abeta proteotoxicity, suggesting that existing drug classes may offer promising avenues for treating age-related neurodegenerative diseases.
