This book takes a thorough look at psychological disorders and the complex nature of pathological lying.

You’ll find detailed discussions on how mental health issues develop, from biological roots to environmental influences, and how they manifest in behavior.

It covers a wide range of disorders, including personality disorders, dissociative conditions, and mood disorders, with a focus on identifying signs, traits, and underlying motives.

Whether you're a clinician, student, or just curious about why some people lie constantly, this book offers practical insights on diagnosis, intervention, and managing the social and legal implications of deception.
