Schizophrenia-related changes in thinking include:
- Lack of concentration or being able to follow a train of thought
- Seeing or hearing things that aren't real (hallucinations)
- Confusing TV and dreams with reality
- Strange ideas that may not make sense (for example, thinking that parents are stealing things or that an evil spirit possesses him or her)
- Paranoia -- thinking that people are after him or talking about him
- Dwelling unreasonably on the past
