A new study examined if DHA, a key ingredient found in fish oil, could be a potential treatment for Alzheimer’s disease.

The study published in the Journal of the American Medical Association looks at the real value of DHA in slowing the rate of a patient’s mental decline.

A number of studies have shown the substance, a key ingredient in fish oil, is depleted in the brains of Alzheimer’s patients brains.

Researchers at Oregon Health and Science University looked at 402 Alzheimer’s patients over an 18-month period, giving one group DHA and a second a placebo.

“It turns out that this substance did not slow the rate of progression in people who already had a diagnosis of Alzheimer’s disease,” said Dr. Joseph F. Quinn.

There was no evidence that the DHA had any adverse effects on the participants in the trial.

Researchers measured a number of factors, including mental function.
