Could you tell me what are signs and symptoms of schizophrenia in a 14 year old girl?

Signs and symptoms: Symtpoms in an adolescent can be similar to that of an adult.They can have hallucinations, paranoia, irritability, irrational thinking, poor hygiene, withdrawal from family and friends, vacant facial expression, poor school performance, difficulty sleeping, and difficulty concentrating.This link has a more detailed list of symptoms. http://www.childrenshospital.org/az/site1561/mainpages1561p1.html.

Varied: Symptoms are varied and can include delusions, hallucinations, disorganized speech and behavior, or even catatonic behavior. However this is a very complex diagnosis and is uncommon in teens her age. Given that you are asking the question, it is time to have her evaluated by a doctor or psychiatrist.
