Lost Connections offers a radical new way of thinking about depression and anxiety. Award-winning journalist Johann Hari presents a challenge to the conventional understanding of mental health, suggesting that the real causes of depression and anxiety are largely rooted in the way we live today. Hari's thorough investigation leads him to discover nine different causes of depression and anxiety, which are not primarily biological, but rather are connected to social and environmental factors.

Hari's journey takes him to a variety of places, from the tunnels beneath Las Vegas to an Amish community in Indiana, and to a Berlin uprising, all of which provide a vivid and dramatic illustration of the new insights into mental health. These insights pave the way for solutions that are markedly different from the traditional approaches, offering real hope for those affected by these conditions.

Lost Connections not only transforms our understanding of depression and anxiety but also prompts a broader debate on the subject, emphasizing the need for collective efforts to end the epidemic of mental health issues.
