MONDAY, Sept. 8, 2014 (HealthDay News) -- Low doses of fish oil may help reduce the number of seizures experienced by people with a form of tough-to-treat epilepsy that no longer responds to drugs, a small new study suggests.
The research was led by Dr. Christopher DeGiorgio, of the University of California, Los Angeles, and included 24 people with epilepsy that could no longer be controlled using medications.
One expert not connected to the study said many people with epilepsy remain without adequate treatment.
"Although medications remain the primary treatment for newly diagnosed epilepsy, more than 35 percent of patients continue to have seizures despite taking antiepileptic drugs," said Dr. David Friedman, director of the Comprehensive Epilepsy Center at Winthrop University Hospital in Mineola, N.Y.
Friedman said that in these cases, patients often resort to alternative treatments such as epilepsy surgeries, special diets or brain-stimulating devices. So the new study using a common nutrient is intriguing, he said.
In the study, the UCLA team gave the patients three separate treatments, each lasting 10 weeks and separated by a period of six weeks.
The treatments were: the "low-dose" intervention of three capsules of fish oil (about 1,080 milligrams) a day plus three "dummy" capsules containing corn oil only; the "high-dose" involving six capsules of fish oil a day, and a placebo treatment of three capsules of corn oil taken twice a day.
The average number of seizures while taking the low dose of fish oil was about 12 a month, compared with just over 17 when taking a high dose of fish oil, and just over 18 when taking the corn oil only.
Two people were completely free of seizures while taking a low dose of fish oil. This did not occur while patients were taking a high dose of fish oil or corn oil.
A low dose of fish oil was also associated with a slight decrease in blood pressure, while a high dose of fish oil was associated with a slight increase. Taking fish oil was not associated with any changes in heart rate, blood fat levels or severity of seizures, the researchers found.
