Abstract While chronological age is a strong predictor for health-related risk factors, it an incomplete metric that fails to fully characterize the unique aging process of individuals with different genetic makeup, neurodevelopment, and environmental experiences. Recent advances in epigenomic array technologies have made possible generate DNA methylation-based biomarkers biological aging, which may be useful predicting myriad cognitive abilities functional brain network organization across older individuals. It currently unclear domains are negatively correlated epigenetic above beyond age, unknown if important mechanism explaining these associations. In this study, accelerated (i.e. AgeAccelGrim) performed worse on tasks spanned wide variety faculties including both fluid crystallized intelligence ( N = 103, average 68.98 years, 73 females, 30 males). Additionally, fMRI connectome-based predictive models suggested mediating connectivity acceleration-cognition associations primarily medial temporal lobe limbic structures.

Ageing is the greatest risk factor of late-onset neurodegenerative diseases. In realm sporadic tauopathies, modelling process biological ageing in experimental animals forms foundation searching for molecular origin pathogenic tau and developing potential therapeutic interventions. Although prior research into transgenic models offers valuable lessons studying how mutations overexpression can drive pathologies, underlying mechanisms by which leads to abnormal accumulation remains poorly understood. Mutations associated with human progeroid syndromes have been proposed be able mimic an aged environment animal models. Here, we summarise recent attempts relation tauopathies using that carry syndromes, or genetic elements unrelated exceptional natural lifespans, a remarkable resistance ageing-related disorders.

The proportion of older adults within society is sharply increasing and a better understanding how we age starts to be critical. However, given the paucity longitudinal studies with both neuroimaging epigenetic data, it remains largely unknown whether speed clock changes over life course any such are proportional in brain aging cognitive skills. To fill these knowledge gaps, conducted study prenatal birth cohort, studied across adolescence young adulthood, evaluated its relationship outcomes.DNA methylation was assessed using Illumina EPIC Platform adolescence, early late 20 s, DNA estimated Horvath's clock, gap (EpiAGE) calculated as residualized for batch, chronological epithelial cells.

The growing phenomenon of population aging is redefining demographic dynamics, intensifying age-related conditions, especially dementia, projected to triple by 2050 with an enormous global economic burden. This study investigates visual arts-mediated Cognitive Activation Therapy (CAT) as a non-pharmacological CAT intervention targets both biological [leukocyte telomere length (LTL), DNA methylation age (DNAmAge)] and cognitive functionality. Aligning broader trend integrating approaches into dementia care. longitudinal involved 20 patients mild moderate neurocognitive disorders. functional assessments, markers -i.e., LTL DNAmAge- were analyzed before after intervention.

Aging has always been considered as a risk factor for neurodegenerative diseases, but there are individual differences and its mechanism is not yet clear. Epigenetics may unveil the relationship between aging diseases. Our study employed bidirectional two-sample Mendelian randomization (MR) design to assess potential causal association epigenetic We utilized publicly available summary datasets from several genome-wide studies (GWAS). investigation focused on multiple measures of age exposures outcomes, while occurrence diseases served outcomes. Sensitivity analyses confirmed accuracy results. The results show significant decrease in Parkinson's disease with GrimAge (OR = 0.8862, 95% CI 0.7914-0.9924, p 0.03638). Additionally, we identified that HannumAge was linked an increased Multiple Sclerosis 1.0707, 1.0056-1.1401, 0.03295).

Atrial fibrillation (AF) is the most common arrhythmia in humans. AF characterized by irregular and increased atrial muscle activation. This high-frequency activation obliterates synchronous work of atria ventricles, reducing myocardial performance, which can lead to severe heart failure or stroke. The risk developing depends largely on patient's history. Cardiovascular diseases are considered aging-related pathologies; therefore, deciphering role telomeres DNA methylation (mDNA), two hallmarks aging, likely contribute a better understanding prophylaxis AF. In honor Prof. Elizabeth Blackburn's 75th birthday, we dedicate this review discovery her contribution research aging.
