“Chemo brain” affects up to 80% of people receiving chemotherapy, making everyday tasks harder. In a new trial, cancer patients who followed a home-based exercise program showed better attention and fewer noticeable cognitive problems than those who received a placebo. Low-dose ibuprofen also improved some cognitive measures, though its effects were less consistent.

A study of more than 2,100 adults found that eating more ultra-processed foods was linked to poorer attention and slower mental processing, even among people with otherwise healthy diets. Researchers also found higher consumption was associated with increased dementia risk factors, raising concerns about the hidden cognitive costs of heavily processed foods.

A surprising gut-heart connection may help explain why sleep apnea increases the risk of cardiovascular disease. In mice, disabling a bile acid receptor called FXR sharply reduced plaque buildup, opening the door to potential new treatments based on gut microbes and their chemical signals.

Tea may help protect against heart disease, diabetes, cancer, cognitive decline, and age related muscle loss, according to a major review. But the way you drink it matters, since bottled and bubble teas often contain ingredients that can diminish tea's health benefits.

CONCLUSIONS: Maintaining favorable long-term patterns of PA, even with gradual decline, is associated with reduced odds of DS among older adults with chronic diseases. These findings support PA as a potentially cost-effective strategy for secondary prevention and highlight the importance of sustained behavioral patterns in mitigating mental health risks in aging populations.

CONCLUSION: Frailty is common among Iranian older adults and is independently associated with poorer physical QoL and, to a lesser extent, mental QoL. These findings support the need for targeted screening and multidomain interventions.
