Study: Fish Oil
May Reduce Risk of Psychosis
Reported February 02, 2010
(Feb. 2) -- Patients
at a high risk of developing schizophrenia are often treated with low-dose
anti-psychotics in a bid to ward off the disorder. Now, a study published in
the Archives of General Psychiatry suggests that fish oil might offer
similar benefits with fewer potential side effects.
A Vienna-based study looked at whether regular doses of fish oil could
prevent schizophrenia among young, at-risk patients age 13 to 25. Of the 81
study participants, 41 were given fish oil tablets four times a day, for
three months. Only two patients in the fish oil group developed a psychotic
disorder a year later, while 11 of the placebo group did.
Previous studies have suggested a link between fatty acids, like those found
in fish, and mental health. And in countries such as Norway and Japan, where
fish is a major dietary staple, mental illnesses are less prevalent.
Using fish oil to treat or prevent mental illness is based on a hypothesis
that disorders such as schizophrenia develop because of the body's inability
to properly manage fatty acid absorption, leading to brain cell damage.
Researchers speculate that the omega-3 fatty acids in fish oil might help
repair those cells. Omega-3s are also integral to the release of dopamine
and serotonin, two brain chemicals implicated in schizophrenia.
And no need for large
doses; this study prescribed 1,200 milligrams a day, which costs less than
40 cents and is approximately what's already recommended for heart health by
the American Heart Association.
Other preliminary studies suggest that fish oil might protect against
Parkinson's and Alzheimer's, and slow the progression of prostate cancer.
But researchers advise caution in choosing a supplement. After growing
concerns about contamination, the University of Guelph launched an
International Fish Oil Standards program, offering third-party validation of
a supplement's safety.
Next up for the research team is a larger, international study of 320
at-risk patients, in hopes of replicating the findings and lending more
credence to the potential for omega-3 supplements as a preventive mental
health medicine.
