— 作者: Researchers have identified potential chemical warning signs in the brain that may signal an increased risk of dementia long before symptoms appear. According to findings, nearly 45% of dementia cases are considered preventable through lifestyle choices such as regular exercise, a healthy diet, and maintaining social connections. The study suggests these lifestyle factors could influence brain chemistry in ways that might predict cognitive decline. The research highlights the possibility that changes in brain chemicals linked to lifestyle habits could serve as early indicators of dementia risk. While no specific symptoms may be present at this stage, these chemical shifts could provide valuable insights into the underlying processes contributing to cognitive deterioration. Scientists emphasize the importance of understanding how modifiable behaviors impact brain health over time, potentially offering new avenues for prevention strategies aimed at reducing dementia rates globally.
