Although changes in the body during aging are a natural process, the question arises whether the brain ages in the same way as the body, and if this happens uniformly across all individuals. This issue is relevant because some people between the ages of 70 and 80 remain highly active, engaging in learning and writing, while others may experience difficulties with cognitive functions and forgetfulness.
Currently, scientists are using artificial intelligence (AI) to find answers to these questions. The goal of the research is to understand the rates of brain aging and determine which groups of people may face an increased risk of memory problems in the future. Special attention is paid to the link between lifestyle, nutrition, and brain health.
In California, USA, scientists have been studying the lifestyles of Seventh-day Adventist community members for many years. These individuals typically adhere to a plant-based diet, exercise regularly, live communally, and share their experiences. Furthermore, they abstain from alcohol and caffeine. According to scientists, a healthy lifestyle positively affects not only life expectancy but also brain health, preventing premature aging.
Scientists are also working on a new method that allows for the detection of brain changes using AI-enhanced MRI scans. Researchers at the University of Southern California used MRI data from thousands of brains to create computer models. Using these models, AI attempts to determine how a healthy lifestyle affects the brain in old age. Scientists note that people who maintain a healthy lifestyle in old age retain good brain function. Scientists are also interested in the possibility of early detection of age-related brain changes using AI and MRI, which would allow doctors to prescribe treatment in a timely manner.
According to a BBC report, the study of this community showed that social activity is critically important for maintaining brain health. Interacting with people, maintaining connections with family and friends, and acquiring new knowledge help keep the brain toned. In addition, lifestyle and nutrition play an important role. Conversely, prolonged loneliness negatively affects mental health and the brain, accelerating its aging.
To maintain good brain health, it is recommended to exercise regularly, try to get enough sleep, avoid smoking and excessive alcohol consumption, control blood pressure, sugar, and cholesterol levels, and constantly learn new things.
