Predicting Maximum Lifespan Limits at Mean Menopausal Age

引用

Journal of Mathematical Research with Applications 2025年第1期 133-142页

作者： M.SUMATHI S.AnTOnY CARLA Department of Mathematics N.M.S.S.Vellaichamy Nadar College Research Scholar (Part-time) Madurai Kamaraj University

The age at which a woman enters natural menopause has also been associated to death from any cause. Menopause is a natural component of aging that happens between the ages of 45 and 55, with the average menopausal age being 51. Previous research has revealed the age at which women reach menopause, but there is no evidence to support the link between menopause and longevity. We made a study in assessing the limits of maximum lifespan at menopausal age in our previous article. In this paper, we aim to predict the maximum lifespan of women at mean menopausal age.

With increasing age,humans become more susceptible to the onset of neurodegenerative diseases(nDs),and among these,Alzheimer's disease(AD)is the most frequent(nicoletti et al.,2023).nDs are primarily characterized by neuronal loss and atrophy,but also by lesions involving the cerebral and/or cardiovascular system(Balistreri,2021).Lesions such as macroinfa rcts,microinfarcts,hemorrhages,white matter lesions,atherosclerosis,and arteriolosclerosis have also been significantly described in the preclinical stages of cognitive impairment characterizing nDs(Mariani et al.,2007).
