Symptoms and Causes of Schizophrenia

According to WebMD, schizophrenia is “a serious brain disorder that distorts the way a person thinks, acts, expresses emotions, perceives reality, and relates to others.“ This makes it challenging to function as normal, whether at work or school, or when interacting with others.

Although schizophrenia is not a very common condition—affecting only about 1 percent of the worldwide population—it can be quite chronic and disabling. And while it’s not curable, it can be managed with proper treatment. Therefore, it’s important to understand what causes schizophrenia, as well as what symptoms to look out for.


1. Delusions

Delusions are an incredibly common symptom associated with schizophrenia. In fact, HelpGuide.org indicates that they occur in “more than 90% of those who have the disorder.” Some of the most common types include delusions of persecution, where individuals believe that someone is out to get them, and delusions of reference, where “A neutral environmental event is believed to have a special and personal meaning,” such as believing someone on TV is speaking directly to them.

People with schizophrenia may also believe they are someone famous or important, like a celebrity, or that they have special powers. This type is known as delusions of grandeur. Or they may believe that their “thoughts or actions are being controlled by outside, alien forces”—known as delusions of control.
