I am a 32 year old female and I have been diagnosed with persistent migraine aura for the past 7 months. I was previously living in the Caribbean where I attended medical school for the 8 months prior to this. I don't feel as though the diagnosis is correct as I have only had 2 migraine headaches in the past and none of the treatments have worked thus far. I have had all the tests done, MRI brain & neck, CT angio head, lumbar puncture, etc. and all are normal. I continue to experience light sensitivity, burning in my head, poor night vision and its like I can see little things moving in my eyes. I have just recently tested high for mercury and I am presently being treated with DMSA, a chelator. I am now wondering if there is a possibility of parasites, since I lived in the Caribbean and ate a lot of the local fish, etc. Any thoughts would be much appreciated.

  • I live in the Caribbean and have eaten the local fish many times with no problems. If the fish you ate was well cooked it is very unlikely that you could contract a parasite from the fish.I will say that there has been an explosion of restaurants selling sushi here and if you have been eating sushi then it is possible to become infected with a parasite. Most Sushi fish are not local Caribbean fish and most of the fish are inspected for parasites.Diphyllobothrium latum is a common parasite of fresh water fish and like a lot of fish parasites it needs a mollusk or snail to complete its life cycle and these snails are not found in the Caribbean. This organism is most commonly found in Asia although it has been found in Peru and ChiliEchinostoma sp is another Asian fish parasite that infects humansIn fact the only fish parasite that I could find that is world wide so could be found in the Caribbean is Dioctophyme which causes kidney infections but again only from raw or undercooked fish.Only two marine fish parasites have been reported in Caribbean fish although the article says there are bound to be more. These are intestinal worms and are unlikely to produce the symptoms you refer to. (Jorge Cortes Marine biodiversity of Costa Rica etc 2008)And as a medical student you should know that an Ova and Parasite test (O & P) can be done on you, if you feel you have a parasite.Everyone has eye floaters and this is probably nothing to do with a parasite infection.I know very little about mercury poisoning and migrains but feel these are more likely than a parasite infection although if you walked around barefoot where there are stray dogs you might have a whipworm infection.:cool:Best wishes for good health

  • How are your stools? Any digestion problems - gas/bloating/cramping etc? These problems would point more to pathogens like parasites. A stool exam can help detect, but parasites are often hard to find in the stool. I would suggest getting your B12 levels tested as B12 deficiency can cause the symptoms you describe. Your high mercury could be due to fish eating - how are you doing with the DMSA? Vit C may be helpful. Best wishesDOM

  • Hi Vanessa,
    Were you able to solve this issue? I am a 42 yrs old female suffering from a supposed persistent migraine aura for two years now. I'd love to know if you found a solution to your problem that might help me too. Kind regards, Charlotte, Dubai
