Schizophrenia is a mental health disorder that causes people to misinterpret reality and seriously affects their daily lives. It’s rarer than other mental illnesses, but the condition still affects around 24 million people worldwide.2 Along with delusions, hallucinations, and disorganized speech or thought, symptoms of schizophrenia can include lack of eye contact, reduced range of emotions, poor hygiene, and lack of motivation. While people with schizophrenia often have psychosis as a symptom, a person experiencing psychosis doesn’t necessarily have schizophrenia.
