More, particularly regarding the prevention and research of neurodegenerative diseases such as Alzheimer’s and Parkinson. At the same time, it is essential to protect psychological health, which is challenged by social, healthcare, and geopolitical complexities. Yet, research increasingly shows that preserving brain health and protecting mental well-being is a single, unified mission, with two interconnected aspects to be nurtured through awareness and healthy lifestyles. Taking care of our emotional and psychosocial well-beingThe concept of well-being is central to each of our lives, b... More today can also help preserve our brain health, for the benefit of ourselves and our loved ones.

Psychological stress and oxidative stress

We often hear about oxidative stressFrom a clinical point of view, stress is a physiological and... More, which is sometimes confused with psychological stress. However, these are two distinct yet related processes. Oxidative stress refers to the mechanism of cellular damage caused by the accumulation of free radicals. It is triggered by factors such as pollution, an unbalanced diet, smokingMuch more than a habit: a global health issue Smoking is oft... More, alcohol abuse, and drug use. Oxidative stress plays a role in the development of neurodegenerative diseases, such as Alzheimer’s and Parkinson’s. A 2009 scientific review investigated the relationship between oxidative stress and emotional stress, focusing particularly on the causal role of oxidative stress in anxietyAnxiety is an emotional response characterized by feelings o...

Stress and neuroinflammation

Neurodegenerative diseases are also characterized by neuroinflammationNeuroinflammation is a pathological process that involves th... More, linked to oxidative stress through mutually influencing processes. Particularly promising for neurodegeneration prevention is the study of the relationship between psychological stress and neuroinflammation. Research focuses on the microglia, immune cells of the Central Nervous System, whose activation is studied as an indicator of neuroinflammation. A 2016 review demonstrates the role of psychological stress in brain neuroinflammation, investigating the effect of stress on microglial activity. Results confirm that a series of psychosocial stress factors lead to elevated microglial activity in the hippocampusThe hippocampus is a part of the brain located in the inner ...

Depression and neuroinflammation

A 2020 review investigates the influence of brain inflammation on major depression, with microglial activation. The study suggests that counteracting brain inflammation could be a therapeutic target for depression treatment. Depression, in turn, has already been studied as a possible causal factor or very early prodromal symptom of dementiaDementia is a medical condition characterized by the progres... More, Parkinson’s, and Alzheimer’s, which exhibit neuroinflammation. A study from the University of Siena highlights the bidirectional effect between depression and neuroinflammation. The two conditions are closely connected and can feed each other: the inflammatory response can lead to depression, and depression can contribute to inflammation.

The importance of lifestyle

Science increasingly uncovers correlations, causal relationships, and likely mutual interactions between psychological stress, neuroinflammation, and neurodegeneration. Studies reveal the deep biochemical connectionConnection: the human need that precedes all technology Conn... More between brain health and mental well-being, between cognitive functions and emotional well-being. Protecting the brain and psychological health is an achievable goal that benefits the whole organism and, by extension and connection, the family and community. We can prevent neuroinflammation and slow the epigenetic clock by taking responsible actions regarding our lifestyle.

A key factor is nutrition. Scientific studies focus on the gut-brain-microbiota axis, showing the role of the gastrointestinal microbiota in regulating neuroinflammation. Neuroinflammation, in turn, can promote stress-related disorders, which may affect the microbiota, creating a vicious or virtuous cycle of intestinal, mental, and brain health. Physical activity is essential to counter neuroinflammation and neurodegeneration, even more effective when integrated with meditative and contemplative practices. The Patrizio Paoletti Foundation develops and studies these forms of mindful movement, such as Quadrato Motor Training, whose practice has shown significant benefits on cognitive functions and neural plasticity.

Self-care: an act of responsibility

Central remains self-care, of our body and inner world. It is essential to learn how to preserve and regenerate energy, placing global health, which is also emotional, first. Taking care of oneself, protecting oneself from stress and depression, without relegating it to the bottom of our priority list, is an act of awareness and responsibility, also toward family, colleagues, and friends. They all benefit positively from the cultivation of our health.

If the exploration of the precise biochemical mechanisms linking brain and mind health, body, and psyche is still in its infancy, it is clear that the interaction and integration of systems reminds us of the deep connection and interdependence that characterizes life. Recognizing and honoring this interdependence allows us to care for increasingly larger systems, starting from the body, extending to family, community, and the Planet.
