A new study has found that a tendency to extract spurious messages from noise could be an early sign of schizophrenia.
Researchers at the Yale School of Medicine diagnosed 43 participants with "prodromal symptoms," meaning they exhibited early warning signs of mental illness such as social withdrawal, mild perceptual alterations, or misinterpretation of social cues.
Schizophrenia
Schizophrenia is a mental disorder characterized by symptoms of thought, behavior and social problems.

For the study, researchers randomly assigned participants to take the anti-psychotic medication olanzapine or a placebo, and then assessed their symptoms and neuropsychological function for up to two years.
During the "babble task," participants listened with headphones to overlapping recordings of six speakers reading neutral texts, which made the words virtually incomprehensible. The participants were asked to repeat any words or phrases that they heard. Only four words—"increase," "children," "A-OK," and "Republican"—were consistently reproduced.

Researchers have shed more light on how schizophrenia develops, by discovering major clues behind the growth of the disease.
Analysis showed that 80 percent of the participants who "heard" phrases of four or more words in length went on to develop a schizophrenia-related illness during times that they were not taking olanzapine. In contrast, only six percent of those in the study converted to schizophrenia-related illness if the phrases "heard" were less than three words in length.
"A tendency to extract message-like meaning from meaningless sensory information can, over time, produce a 'matrix of unreality' that triggers the initial psychotic phase of schizophrenia-spectrum disorders," said lead author, Ralph Hoffman, M.D., associate professor of psychiatry.
He said further research is needed because of the small size of this study.
However, if these findings are verified, Hoffman added, they could provide an inexpensive tool for identifying those individuals with early warning signs of schizophrenia who would most likely benefit from preventive drug therapy.
The study is published in the British Journal of Psychiatry.
