The positive effects of omega-3 supplementation seen in patients at high risk of psychosis in a previous randomised, controlled trial may be sustained, the investigators reported at the International Early Psychosis Conference in Tokyo, Japan.
When followed up a median of 6.7 years after the original intervention, just four (9.8%) of 41 patients in the omega-3 group had transitioned to psychosis, compared with 16 (40.0%) of 40 patients given placebo.
