What is Psychosis?
We began the Preface with a list of questions that people experiencing psychosis and their family members often have. As we mentioned, an episode of psychosis can be frightening, confusing, and painful for the individual going through it and for his or her family members. We also noted that this book is meant to help readers through a very difficult time by providing much needed information. Part 1 of this book, Answering Your Basic Questions, focuses on explaining some of the most important facts about psychosis. This chapter addresses the first basic question, what is psychosis? In this chapter, we define what psychosis is and then dispel some myths by describing what psychosis is not. We then briefly describe what percentage of people develop psychosis and when it usually first begins. Next, we present the idea of a “psychosis continuum,” which means that experiences of psychosis can differ in level of seriousness. We then set the stage for later chapters by briefly introducing schizophrenia (one of the illnesses that is related to psychosis) and several other topics to come later in the book, including causes of psychosis, treatments, and recovery. Psychosis is a form of mental illness. A mental illness affects a person’s thoughts, feelings, and behaviors. Like physical illnesses, mental illnesses are treatable. Psychosis is a treatable mental illness syndrome. You may be familiar with some other mental illness syndromes, such as depression, posttraumatic stress disorder, and panic attacks. So what exactly does psychosis mean? Psychosis is a word used to describe a person’s mental state when he or she is out of touch with reality. For example, a person might hear voices that are not really there (auditory hallucinations) or believe things that are not really true (delusions). Psychosis is a medical condition that occurs due to a dysfunction in the brain. People with psychosis have difficulty separating false personal experiences from reality. They may behave in a bizarre or risky manner without realizing that they are doing anything unusual. Similar to any other health condition, psychosis consists of a combination of both symptoms that patients experience and signs that doctors observe.
