Researchers say:
"People with schizophrenia who experience auditory hallucinations tend to hear what they expect, an exaggerated version of a perceptual distortion that is common among other people without hallucinations, researchers at Columbia University Irving Medical Center (CUIMC) and New York State Psychiatric Institute (NYSPI) have found.
Those with hallucinations and other psychotic symptoms are known to have elevated dopamine, the main area of focus for available treatments for psychosis, but it was unclear how this could lead to hallucinations. The researchers found that elevated dopamine could make some patients rely more on expectations, which could then result in hallucinations.
The findings explain why treatments targeting the production of dopamine could help alleviate this condition."
