“In fact, people who regularly engage in moderate leisure time physical activity are less likely to develop cardiovascular disease than people who are inactive. Findings from a 2019 study suggest that just 30 minutes of moderate exercise daily reduces the risk of experiencing a ruptured brain aneurysm.”

“Another notable finding from the current study - a connection between resisting compulsions and brain inflammation - provides one indicator. At least nine out of 10 people with OCD carry out compulsions, the actions or rituals that people do to try to reduce their obsessions.”

“Excess body fat harms multiple organ systems, including the central nervous system, potentially accelerating brain aging. A new study shows that a 1 percent weight loss delays brain aging by nearly nine months.”

“Other aspects of their decision-making, such as how accurate or risk-taking they were, did not show the same relationship. In early childhood, brain networks are still maturing and becoming more specialized in how they interact with one another.”

“Hypocretin is produced primarily in the hypothalamus, where it is involved in aspects of wakefulness and appetite. The investigators used optogenetics to study and record the activity of hypocretin-producing neurons in the brains of young and old mice.”

“Dr. Mattson also has found that meal-skipping diets can stimulate brain cells in mice to produce a protein called brain-derived neurotrophic factor (BDNF) that promotes the survival and growth of nerve cells. Publication.”

“For example, some people with COVID-19 experience headaches, nausea, vomiting, or "brain fog" – indicators of neurological involvement. Evidence from a 2020 study suggests that SARS-CoV-2, the virus that causes COVID-19, disrupts the blood-brain barrier.”

“Instead, the exercise-induced changes in blood flow indicate a compensatory mechanism to shift brain activity to other regions. These findings suggest that exercise can forestall the effects of age-related cognitive decline.”

“Beneath the thicker cortical regions, the amount of white matter, which carries signals between brain areas, was reduced. One key fiber bundle that connects movement-related brain regions showed signs of altered microstructure, consistent with either tighter packing of nerve fibers or differences in myelin, the fatty insulation that surrounds nerve fibers and helps signals travel quickly.”

“Similarly, human teens who used cannabis had thinner cortex regions. Further analysis linked these structural changes to genes involved in brain development, including processes like learning and memory.”
