Scientists Reveal How Exercise Protects the Brain From Alzheimer’s

Scientists reveal how exercise protects the brain from Alzheimer’s

Exercise may sharpen the mind by repairing the brain’s protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein causing the blood-brain barrier to become leaky with age. In older mice, dialing down this protein reduced inflammation and improved memory. The discovery points to a surprising body-to-brain pathway that could inspire new Alzheimer’s therapies.

Scientists discover a liver-to-brain signal that mimics exercise benefits

Researchers have identified a specific liver protein produced during exercise that strengthens the brain’s protective barrier and improves memory in aging mice. This finding suggests a potential pharmaceutical avenue to mimic the cognitive benefits of physical activity for older adults who cannot exercise. The study was published in the journal Cell. For decades, medical professionals have recognized that aerobic exercise promotes brain health. …

Simple Daily Habits May Lower Alzheimer’s Risk by 38%

New research suggests that maintaining straightforward lifestyle habits throughout life could significantly lower the likelihood of developing Alzheimer’s disease, with findings indicating a potential risk reduction of up to 38 percent for those who adopt these behaviors.

Scientists find a mechanism showing how exercise protects the brain

Researchers at UC San Francisco have discovered a mechanism that could explain how exercise improves cognition by shoring up the brain’s protective barrier. With age, the network of blood vessels—called the blood–brain barrier—gets leaky, letting harmful compounds enter the brain. This causes inflammation, which is associated with cognitive decline and is seen in conditions like […] The post Scientists find a mechanism showing how exercise prote…
