What does psychotic mean?

Psychosis is a mental condition that 1 out of 13 people worldwide is projected to experience at least once before the age of 75. We discuss psychosis at the level of the brain and genome, and how stressful life events can precipitate it in some people but not others, as well as what it feels and looks like, why and to whom it happens, how it affects dreams, the roles stress and drugs can play, and strategies to prevent it from happening.
