well i would not jump the gun on the EPA being the only relevant thing here. we do not know why the doc suggested the fish oil. as i see it, it would be good to ask the doc her reason for suggesting the fish oil, to find out whether EPA intake all she is after and/or to discuss what a suitable ratio of EPA to DHA would be, for her purposes.
because it's not like DHA is junk. while DHA and EPA have some common properties,
each offers distinct benefits that the other does not.

Summary
EPA and DHA do different things, so you need them both, especially for the brain. If your goal is reducing cellular inflammation, then you probably need more EPA than DHA. How much more? Probably twice the levels, nonetheless you always cover your bets with omega-3 fatty acids by using both EPA and DHA at the same time.
