What Is Schizophrenia?

Schizophrenia is a confusing term and its meaning has changed over time. People often confuse it with someone having multiple personalities, which is a different condition. It's been characterized as a condition where a person has frequent episodes of not being able to distinguish between what's real and what's not. There isn't a good, concise definition of schizophrenia - the definitions that are out there tend to be loose grab bags of symptoms.
