Scientists try to stop schizophrenia in its tracks

Interesting story on schizophrenia "prodrome" - the early symptoms of possible coming psychosis:

In the prodrome, people can see and hear imaginary things or have odd thoughts. But significantly, they understand these experiences are just illusions, or they have a reasonable explanation.

In contrast, people with psychosis firmly cling to unreasonable explanations instead. When someone interprets an odd halo of light over a bedroom doorway as an urgent message from a dead relative, "that's when they have gone over to the psychotic side," said Dr. Thomas McGlashan, a Yale University psychiatry professor.

Either that or they are misinterpreting a message from the Mysterons.
