Fight Aging! Newsletter, December 4th 2023
This study produced a great deal of data that continues to be mined for insights into human aging and effects of calorie restriction in a long-lived species such as our own, to contrast with the sizable effects on health and longevity in short-lived species such as mice.
In particular, and the topic for today, cellular senescence and its role in degenerative aging has garnered far greater interest in the research community in the years since the CALERIE study took place. Thus in today's open access paper, scientists examine CALERIE study data to find evidence for calorie restriction to reduce the burden of cellular ...

Frailty Correlates with Hearing Loss in Later Life
Many seemingly unrelated aspects of aging correlate with one another in incidence and progression. All of the myriad manifestations of degeneration aging arise from the same small set of underlying processes of cell and tissue damage, so such correlations are perhaps unsurprising. There are cases in which a direct causal connection is found, as in the case of hearing loss contributing to dementia, but in the case of hearing loss and frailty we might expect correlation to arise from shared underlying mechanisms, such as the chronic inflammation that is characteristic of later life.
In a nationally representative sa...

Intestinal Inflammation Increases with Age, and is Greater Still in Patients with Alzheimer's Disease
16s rRNA sequencing allows the microbial populations resident in the gut to be catalogued in detail: which species are present, and relative numbers by species. In the years since this assay became cheap, reliable, and readily available, researchers have built increasingly large human gut microbiome databases from samples obtained over the course of epidemiological studies. The research community has found that the gut microbiome exhibits characteristic differences in older people, marked by a growth in populations of inflammatory microbes and a loss of those species that produce beneficial metabolites. Further, some age-r...

Age-Related Hearing Loss Correlates with Microstructural Change in the Brain
Researchers here note correlations between hearing loss and specific microstructural changes in the brain indicative of loss of function. Evidence from studies involving patients with and without hearing aids suggests that hearing loss accelerates age-related neurodegeneration. Depriving the brain of sensory processing activity may produce maladaptive compensatory changes, or may simply be a case of "use it or lose it", as is the case for muscle tissue. The mechanisms involved are not yet fully understood, and the situation is complicated by underlying processes of aging that contribute separately to dysfunction in both th...

Visceral Fat Increases Brain Inflammation and Amyloid Aggregation
The correlation between being overweight and risk of developing Alzheimer's disease is nowhere near as strong as, say, between being overweight and risk of developing type 2 diabetes. Given the evidence for chronic inflammation to be important in the development of Alzheimer's disease, and the many ways in which excess visceral fat tissue promotes chronic inflammation, it is somewhat puzzling that Alzheimer's isn't more of a lifestyle disease, similar to the way in which type 2 diabetes derives from lifestyle choices. That said, there is a contribution to Alzheimer's risk, and carrying excess weight is unwise, for this and...

Further Evidence for Reduced Blood Pressure to Lower Risk of Dementia
The raised blood pressure of hypertension causes a great deal of downstream damage. It is a way for low-level biochemical damage associated with aging to become actual physical damage to the body. Pressure damage can occur in delicate tissues throughout the body, and raised blood pressure increases the pace at which capillaries and other small vessels rupture. Further, increased blood pressure can accelerate the development of atherosclerosis, and also contributes to the pathological enlargement and weakening of heart muscle. All of this downstream harm is why forcing a reduction in blood pressure, without addressing any o...
