Anxiety is the most prevalent psychiatric problem of our time. Decades of research have gone into probing its mysteries and developing treatments. But what if we've been thinking about fear and anxiety in the wrong way for all these years? This is the groundbreaking premise behind a wave of new research, led by the lab of renowned neuroscientist Joseph LeDoux. He believes that fear and anxiety are not innate states, simply waiting to be unleashed in the brain. Rather they are assembled experiences, and that has huge implications for patients. By mapping brain circuits, LeDoux explains the origins of anxiety disorders and reveals discoveries that can restore sufferers to normality. As impressive as it is timely, Anxious is a comprehensive survey of cutting-edge research revolutionising the way we treat our most pressing mental health issue.
