The Importance of Neuroscience in Understanding Aging and Health
In 2021, the United Nations declared the decade 2021-2030 as the “Decade of Healthy Aging,” which aims to improve the lives of older people, their families, and communities through joint efforts between governments, civil society, international agencies, academia, research institutions, and businesses. The focus is on enhancing the quality of life for those over 60 years old, especially in countries with low or very low incomes, who often face significant barriers to accessing essential resources in old age, making their lives difficult and miserable.
However, the situation is different in many developed countries, including Italy, where it is easier and safer to age healthily. So, what does it mean to age healthily? We refer to the overall physical and mental well-being of a person, access to medical care, ability to live independently, quality of life, social relationships, cognitive abilities, and more.
Science is currently directing much research on identifying factors that protect against age-related diseases. One of these diseases is Alzheimer’s, which affects many older adults worldwide. Understanding the aging process and how to promote healthy aging is crucial for improving the lives of older people.
In this article, we will explore the importance of neuroscience in understanding aging and health, as well as its potential applications in promoting healthy aging. We will also discuss the latest research findings on Alzheimer’s disease and the role of neuroscience in developing effective interventions to prevent or slow down this devastating condition.
Neuroscience and Healthy Aging
Neuroscience is the scientific study of the structure and function of the brain, nervous system, and behavior. It has made significant progress in recent years, with advancements in imaging techniques, such as functional magnetic resonance imaging (fMRI), and the development of new neurostimulation technologies.
In the context of aging, neuroscience plays a crucial role in understanding the complex changes that occur in the brain over time. As people age, they experience natural changes in their brain structure and function, which can affect cognitive abilities, emotional regulation, and overall health.
One of the key challenges in healthy aging is maintaining cognitive function and preventing neurodegenerative diseases such as Alzheimer’s. Research has shown that there are various factors that contribute to the risk of developing these conditions, including genetics, lifestyle choices, and environmental exposures.
The Role of Biomarkers
Biomarkers are biological molecules that can be used to diagnose or monitor a disease. In the context of Alzheimer’s disease, biomarkers such as amyloid beta and tau proteins in cerebrospinal fluid have been identified as potential indicators of the disease.
Research has also shown that maintaining an active lifestyle, a healthy diet, and managing stress can help reduce the risk of developing neurodegenerative diseases like Alzheimer’s. Exercise, in particular, has been shown to promote blood flow to the brain, boost cognitive function, and even stimulate the growth of new neurons.
The Intersection of Neuroscience and Technology
Advances in neuroscience have also led to the development of new technologies that can be used to diagnose and treat neurodegenerative diseases. For example, transcranial magnetic stimulation (TMS) is a non-invasive technique that uses magnetic fields to stimulate brain activity.
Transcranial electrical stimulation (tES) is another technique that involves applying electrical currents to specific areas of the brain. These technologies have shown promise in treating conditions such as depression and anxiety, but their use for Alzheimer’s disease is still in its early stages.
The Future of Neuroscience Research
Neuroscience research is rapidly advancing, with new technologies and techniques being developed to improve our understanding of the human brain and nervous system.
One of the exciting developments in neuroscience is the use of artificial intelligence (AI) and machine learning algorithms to analyze large datasets and identify patterns that may not be apparent through traditional analysis methods.
Researchers are also exploring ways to create an interface between humans and computers, allowing for direct communication between the brain and machines. This technology has potential applications in fields such as prosthetics, artificial intelligence, and even entertainment.
Conclusion
Healthy aging is a complex issue that requires a comprehensive understanding of the factors that contribute to it. Neuroscience has made significant progress in recent years, and ongoing research holds promise for improving our understanding of this process and developing effective interventions to promote healthy aging.
In particular, researchers are making progress in understanding the role of biomarkers in diagnosing Alzheimer’s disease, as well as the potential benefits of exercise and stress management in reducing the risk of neurodegenerative diseases.
As we look to the future, it is clear that neuroscience will play an increasingly important role in promoting healthy aging. By leveraging advances in technology, interdisciplinary research, and our growing understanding of the human brain, we can develop effective interventions to promote healthier lives for people of all ages.
Interview with Professor Alessandro Vercelli
We had the opportunity to talk to Professor Alessandro Vercelli, Director of Scientific Affairs at the Neuroscience Institute Cavalieri Ottolenghi in Torino, who has been involved in several research projects. He is a professor of human anatomy at the University of Turin and Vice-Rector for Biomedical Research since 2019.
The My Active and Healthy Aging (my-AHA) Study
Professor Vercelli explained that his team conducted a study called “My Active and Healthy Aging” (my-AHA), which aimed to investigate the effects of frailty on older adults. The study involved collaboration with researchers from around the world, including Professor Innocenzo Rainero, who works at the University of Turin’s Department of Neurosciences.
The study focused on 7 countries in Europe, Asia, and Australia between 2016-2020. The goal was to analyze how frailty affects older adults’ quality of life.
The Study’s Findings
Professor Vercelli shared that the results showed that preventing frailty can improve an older person’s quality of life.
Furthermore, he emphasized that there is a positive correlation between a healthy lifestyle and reduced risk of neurodegenerative diseases such as Alzheimer’s.
Interview with Fabiana Pompei
We spoke with Fabiana Pompei from IdeeGreen about the study’s findings and potential future directions for neuroscience research.
Fabiana asked Professor Vercelli if he had seen any evidence that maintaining an active lifestyle could help prevent or slow down neurodegenerative diseases like Alzheimer’s.
Professor Vercelli explained that while there may be some initial results, researchers are currently working on identifying the biochemical mediators responsible for these effects. He also mentioned that his team is exploring new medications to target these issues.
Fabiana Pompei asked about the potential of using biomarkers to diagnose Alzheimer’s disease earlier and improve treatment options.
Professor Vercelli emphasized the importance of understanding how different biomarkers can be used to identify early signs of Alzheimer’s disease.
The Future Outlook for Neuroscience Research
Professor Vercelli discussed the potential future developments in neuroscience, including the integration of multiple levels of investigation and the use of advanced technologies such as TMS and EEG.
He also highlighted the importance of interdisciplinary research in understanding complex systems like the brain.
