Low omega-3 levels are linked to a higher risk of psychosis.
New research has shown that teenagers have higher levels of omega-3 fatty acids acid Less likely to develop a psychotic disorder in their blood in early adulthood, suggesting that this may have a potential preventive effect in reducing the risk of psychosis.
The study, led by researchers from the RCSI University of Medicine and Health Sciences, was published in Translational Psychiatry.
Over 3,800 people in Bristol’s Children of the 90s health study were screened for psychotic disorders, depressive disorders, and generalized anxiety disorders, ages 17 and 24.
These tests took blood samples and measured the levels of omega-6 fatty acids, which generally increase inflammation in the body, and omega-3 fatty acids, which generally reduce inflammation.

While there was little evidence that fatty acids were associated with mental disorders by the age of 17, researchers found that 24-year-olds with psychotic disorders, depressive disorders, and generalized anxiety disorders had higher levels of omega than them. 6- as omega-3 fatty acids without these disorders.
The researchers also found that 24-year-olds with psychotic disorders had lower scores of. exhibited given, an omega-3 fatty acid typically found in oily fish or supplements, as 24-year-olds without psychotic disorders In a group of over 2,700 people who were followed over time, adolescents with higher DHA levels developed with age aged 17, 56% less likely to develop a psychotic disorder seven years later at age 24. This suggests that DHA in adolescence may have a potential preventive effect in reducing the risk of psychosis in early adulthood.
These results remained consistent when other factors such as gender, body mass index, tobacco smoking, and socio-economic status were taken into account.
“The study has to be repeated, but if the results are consistent, these results would suggest that increased dietary intake of omega-3 fatty acids in adolescents, z twenty,” said Professor David Cotter, lead author of the study and professor of molecular Psychiatry at RCSI.
“The results could also raise questions about the relationship between the development of mental disorders and omega-6 fatty acids, which are typically found in vegetable oils.”
David Mongan, RCSI PhD student and Irish Clinical Academic Training (ICAT) Fellow, analyzed the data under the supervision of Professor David Cotter and Professor Mary Cannon of the RCSI Department of Psychiatry.

“We need to do more research to find out more about the mechanisms behind this effect, but it could potentially be related to reducing inflammation or reducing inappropriate clipping of brain connections during adolescence,” said Dr. David Mongan, the first author of the study Psychiatry Intern and PhD student at RCSI.

About kids in the 90s
Children of the 90s, also known as the Avon Longitudinal Study of Parents and Children (ALSPAC), is a long-term health research project run by the University of Bristol that has involved more than 14,000 pregnant women in 1991 and 1992 and has since followed the health and development of parents and their children at the Detail and is currently recruiting the children and siblings of the original children for the study.
