Trauma affects the body and mind and, like a transmissible contagion, can spread among close family and friends, and even across generations and within vast demographic groups. We’re all susceptible. Paul Conti MD says “Trauma is way too prevalent, harmful, contagious, and often invisible—just like a virus.” He understands trauma personally through tragic events that have taken place in his own life. Seventy percent of adults will experience a traumatic event in their lifetime and twenty percent of people who experienced trauma will develop PTSD. Conti who has successfully treated this insidious invisible epidemic for the past 15 years wrote this book to sound the alarm about trauma.He's a graduate of Stanford University School of Medicine, completing his psychiatry training at Stanford and Harvard.
