AN EMERGING DISORDER LINKED TO CLIMATE CHANGE. Eco-anxiety is the chronic fear of an environmental disaster, particularly in relation to global warming. Emerging in the 1990s, this concern is increasingly developing in all countries, especially among younger generations. It is not currently recognized as a diagnosis in psychiatric classifications, but some people (about 3% of the population) experience significant suffering and symptoms that can impair their quality of life. The role of the physician is then to look for an underlying anxiety or depressive disorder, or to assess the intensity of a possible specific Eco-anxiety Disorder. Treatment is based primarily on psychotherapeutic listening, stress and anxiety management methods, and cognitive behavioral therapy aimed at giving the patient better control over their emotions and means of action.
