Once dismissed as unscientific, psychoanalytic therapy is proving to be among our most effective medical treatments of any kind - outperforming psychiatric drugs and rivalling vaccines in its power to prevent and heal. Why does it work so well?

Perhaps because one of the most controversial figures in psychology was right all along.

Neuroscience now confirms much of what Sigmund Freud conjectured over a century ago: our deepest struggles stem, not from chemical imbalances, but from buried memories and unconscious conflicts that no pill can touch.

Using enthralling case studies and cutting-edge brain science, pioneering neuroscientist Mark Solms makes the case that psychoanalysis should resume its position as our master theory of the mind. Yet modern research also reveals where Freud got important things wrong. Could correcting these errors make therapy even more effective?
