 The relationship between brain health and mental health is complex and multifaceted, involving biological, psychological, and social factors. Recent research highlights the interconnectedness of these domains, emphasizing the need for integrated approaches to understanding and improving both brain and mental health. Advances in neuroscience, lifestyle interventions, and public health strategies are reshaping how these areas are addressed, with implications for prevention, diagnosis, and treatment. The following sections explore key aspects of this relationship, drawing on insights from the provided papers.

• Neuroscience has significantly advanced the understanding of mental disorders by identifying biomarkers that aid in diagnosis and personalized treatment. Techniques like Transcranial Magnetic Stimulation (TMS) and neurofeedback are effective in modulating brain activity, particularly for treatment-resistant patients(Andrade et al., 2024).
• Emerging technologies such as artificial intelligence and virtual reality are paving the way for more precise and personalized psychiatric care, though they also present ethical and practical challenges, including privacy concerns and equitable access(Andrade et al., 2024).

• Brain and mental health share common vascular risk factors, such as those associated with stroke, heart disease, and dementia. This overlap suggests that a holistic approach to prevention, focusing on the whole patient rather than isolated symptoms, could mitigate major neurological and mental disorders(Hachinski et al., 2023).
• Lifestyle factors, including diet, exercise, and sleep, play a crucial role in promoting brain health and resilience, which in turn supports mental health. Early adoption of healthy habits can lead to improved cognitive function and overall well-being(Sahakian & Langley, 2025).

• Nutrition and metabolism are critical to brain function and mental health. The energy balance and carbohydrate-insulin models help explain the development of obesity and metabolic dysfunctions, which are linked to neurodegenerative and stress-related mental disorders(Linsmayer et al., 2024).
• Dietary habits, such as calorie restriction and the consumption of "brain food," are important for preventing and treating mental and neurodegenerative diseases, highlighting the role of nutritional medicine in psychiatry(Linsmayer et al., 2024).

• The COVID-19 pandemic has exacerbated health disparities in brain and mental health, particularly among underserved populations. Addressing these inequities requires culturally informed, cross-sectoral approaches that consider biopsychosocial factors and community-level influences(Iyengar et al., 2023).
• The WHO's definition of brain health emphasizes a continuum from well-being to disorders, influenced by physical health, environment, and social factors. This holistic view underscores the intrinsic link between brain and mental health, advocating for integrated public health strategies(Neurology, 2022).

• Despite advances, challenges remain in bridging the gap between brain and mental health. The burden of neurological diseases is high, particularly in low- and middle-income countries, necessitating more neurologists and equitable distribution of resources(Hachinski, 2022).
• The WHO's position paper on brain health calls for a comprehensive approach to optimize brain health across the life course, though further research and debate are needed to refine and operationalize this concept(Neurology, 2022).

While the integration of brain and mental health is gaining momentum, it is essential to consider the broader societal and ethical implications of these advancements. The potential for medicalization and the idealistic nature of current health definitions pose challenges to practical implementation. Moreover, the need for a unified understanding among neurologists and psychiatrists is crucial to effectively address the rising threats of brain and mental illnesses. As research continues to evolve, a balanced approach that considers both individual and systemic factors will be key to improving outcomes in brain and mental health.
