Omega-3, a fatty acid found in oily fish, may prevent the onset of schizophrenia and other psychotic disorders long after being consumed, according to a study released Tuesday.

Up to seven years after taking omega-3 supplements for 12 weeks, at “ultra-high” risk were less likely to have suffered the debilitating condition than a given a placebo, reported the study.

Schizophrenia is characterised by delusions and hallucinations, including hearing voices and seeing things that do not really exist.

It typically emerges during adolescence or , either abruptly or gradually. There is no cure. Current treatment focuses on managing symptoms.

Scientists have long known that patients with schizophrenia exhibit reduced levels of polyunsaturated fatty acid—specifically, omega-3 and omega 6—in cell membranes.

Nearly a decade ago, researchers led by Paul Amminger at the University of Melbourne showed in clinical trials that ingesting the fatty acid delayed a first episode of psychotic disorder in high-risk subjects by up to year.

In a follow up study, published in Nature Communications, Amminger and colleagues report that, nearly seven years later, only 10 percent of the omega-3 group developed psychosis compared to 40 percent in the placebo group.

“We show that omega-3 significantly reduced the risk of progression to psychotic disorder during the entire follow-up period,” the study concluded.
