Fish oil & psychosis (2008)
The study investigated fish oil & psychosis. Individuals at extremely high risk of developing psychosis appear less likely to develop psychotic disorders following a 12-week course of fish oil capsules containing long-chain omega-3 polyunsaturated fatty acids. Those taking the capsules also showed signs of reduced positive, negative and general symptoms of schizophrenia. Schizophrenic patients may have an underlying dysfunction in fatty acid metabolism and the potential effects of omega-3 polyunsaturated fatty acids on psychosis development may result from changes to cell membranes and interactions with neurotransmitter systems in the brain.
