Psychosis is defined as a person who is having difficulty in discerning reality. They've had experiences that they are not clear are real. For example, a person who thinks that someone is out to get them in the absence of all available data, is thought to have a psychotic process. A person who is hearing voices or seeing things that aren't there, is also considered as having, kind of, a core psychotic disorder. It is interesting. When people are made aware of it, they say, "Well, maybe that's not the same kind of psychosis." Many features of psychosis are that people are not able to discern what is not a real, one that other people share. This is common problem with schizophrenia, which is an important problem to discuss on kids in the house because the onset for males is in the teen years, typically. For females, it's typically in the early 20's. There is something about a woman that is particularly protective about the development of schizophrenia. Younger children can have this phenomena of childhood schizophrenia. It's very disturbing to see an 8 or 9 year old child experiencing hallucinations and reporting it. I do want to make a pitch for a program that they have at the National Institute in Bethesda, where they do comprehensive assessments of childhood psychosis. The parents that I've talked to that have children there, get wonderful care.
