¿Es la tristeza una enfermedad?

NUEVA YORK – La tristeza es una de las pocas emociones humanas que han sido reconocidas en todas las sociedades y en todos los tiempos. Algunas de las más antiguas epopeyas conocidas, como La Iliada y Gilgamesh, muestran la tristeza intensa de sus protagonistas después de haber perdido a compañeros cercanos. Del mismo modo, obras antropológicas de una gran variedad de sociedades describen claramente sentimientos de tristeza que se desarrollan debido a la frustración en el amor, a la humillación por parte de un rival o a la incapacidad de alcanzar objetivos culturalmente valiosos.

Incluso, los primates muestran señales fisiológicas y de conducta después de alguna pérdida que son inconfundiblemente similares a la tristeza en los humanos. No hay duda de que la evolución hizo que la gente fuera propensa a ponerse triste después de esas situaciones.

Los trastornos mentales depresivos también se han conocido desde que se llevan registros escritos. En un trabajo escrito en el siglo V a.C., Hipócrates ofreció la primera definición conocida de la melancolía (lo que ahora llamamos “depresión”) como un trastorno definido: “si el temor o la tristeza duran mucho tiempo es melancolía." Los síntomas que Hipócrates relacionó con el trastorno de la melancolía –“aversión a los alimentos, abatimiento, incapacidad para dormir, irritabilidad e inquietud”- son muy similares a los que figuran en las definiciones modernas del trastorno depresivo.

    China in the Lead?

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships. As a major producer of sophisticated components, its long-term trade strategy should focus on gaining deep and unfettered access to integrated cross-border supply chains – and that means adopting a multilateral approach.
