Global economic discussions at the World Economic Forum in Davos saw the launch of the Global Brain Economy Initiative and the companion Global Brain Capital Index, detailed by Rice University’s Harris Eyre. These efforts seek to establish brain health as a measurable development indicator, aiming to stimulate investment in neurological and mental wellness worldwide.
Advocates assert this framework marks a significant pivot, repositioning brain health from a purely welfare concern to a core component of productivity, innovation, and long-term economic resilience. The accompanying flagship report, The Human Advantage: Stronger Brains in the Age of AI, underscores the macro-economic relevance of these challenges across the lifespan.
Professor Eyre noted that brain health conditions currently cost the global economy an estimated $3.5 trillion annually, a figure projected to increase by three percent per year. This economic pressure, stemming from issues ranging from early-life malnutrition to rising dementia rates, necessitates new valuation metrics.
The core concept of brain capital is defined as the combined value of brain health and brain skills, encompassing mental fortitude, cognitive abilities, and emotional resilience. This framework is positioned as 'human capital 2.0' in an era defined by rapid technological change, according to Eyre.
Economist Rym Ayadi, President of the Euro-Mediterranean Economists Association, developed the Global Brain Capital Index to provide a standardized measurement tool. Ayadi stated that the index addresses a blind spot in traditional metrics like GDP, which treat brain health primarily as an expenditure rather than critical infrastructure.
The Index incorporates over 28 indicators across brain health, brain skills, and enabling environments, such as governance and pollution risks. Data presented at Davos indicates a persistent, concerning decline in global brain health indicators since the 1990s, affecting both OECD and non-OECD nations.
While brain health indicators show decline, improvements in certain brain skills, such as educational attainment in some low-income nations, partially offset the negative composite trends. However, speakers warned that sustained underfunding of brain health systems threatens to exacerbate existing global inequalities.
