Studies by scientists have shown that persistent negative thoughts cause serious damage to the human brain and increase the risk of dementia. According to the research findings, constantly focusing on negative thoughts leads to internal erosion of the brain and weakens mental health.
The editorial reports that experts emphasize that a healthy brain naturally tends towards a more optimistic way of thinking. The research notes that when a person dwells on negative thoughts for a long time, the level of cortisol, a stress hormone, rises in the body, and this process leads to the destruction of neurons.
According to scientific observations, prolonged high levels of cortisol weaken memory functions and negatively affect attention and learning abilities. This condition particularly increases the likelihood of dementia and other neurodegenerative diseases in older adults.
Experts state that forming positive thinking habits, managing stress, maintaining psychological balance, and increasing social activity play an important role in protecting mental health. In their opinion, controlling negative thoughts is one of the key conditions for the long-term preservation of brain health.
