In the modern working world, burnout has become an increasingly common phenomenon that affects millions of people. But what exactly is behind the term ¿burnout¿ and how can it be clearly distinguished from mental illnesses such as depression or anxiety disorders? The author presents current research findings on the diagnosis of burnout and provides valuable insights into how burnout can be differentiated from other mental disorders. She highlights the specific characteristics of burnout, including emotional exhaustion and professional cynicism, and explains why a clear differentiation from other mental illnesses such as depression and anxiety is crucial for successful therapy. A central theme of the book is the ongoing debate about the lack of recognition of burnout as a separate illness in international classification systems. The author argues in favour of greater consideration of burnout in future classifications and shows how this recognition could lead to improvements in diagnosis and treatment. In addition, she places an important focus on the necessary research into the biological basis of burnout. The author discusses current findings on the physiological effects of chronic stress, including changes in hormone balance, the immune system and neurological functions. These research findings could lead to a deeper and more comprehensive perspective on the development of burnout and open up new treatment approaches. The book is aimed at those affected as well as professionals who are confronted with stress and burnout in a professional environment. The book offers both theoretical and practical support to help those affected to restore a balance between work and personal well-being and to meet the complex challenges of modern working life.
