Schizophrenia affects an estimated 2.2 million Americans each year. What you should know:
There are no lab tests to find schizophrenia, so doctors usually base a diagnosis on a person’s history and symptoms. They will first rule out other medical causes. In teens, a combination of family history and certain behaviors can help predict the start of schizophrenia.
The period when symptoms first start to arise and before the first episode of psychosis is called the prodromal period. It can last days, weeks or even a years. Sometime it can be difficult to recognize because there is usually no specific trigger. Prodrome is accompanied by what can be perceived as subtle behavioral changes, especially in teens. These behaviors include withdrawing from social groups and expressing unusual suspicions, but that’s not enough for a diagnosis.
