This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to understand why many people develop nerve damage (peripheral neuropathy) with no clear cause. In French Guiana, they suspect local environmental factors—such as mercury exposure from illegal gold mining, tropical virus infections, or traditional plant medicines—may be responsible. This study will compare people with nerve damage to people without it by testing their blood, urine, and hair for heavy metals and viral antibodies, and asking about their use of plant remedies.
About 20–30% of nerve damage cases have no identified cause, even after thorough testing. French Guiana has unique environmental exposures that may explain these mystery cases and make existing nerve problems worse, but no one has studied this connection yet.

You will attend one visit at your hospital in either Cayenne or Saint-Laurent du Maroni. During this visit, doctors will take blood samples, collect urine, and clip a small sample of your hair to test for heavy metals and viral infections. You will also answer questions about any traditional plant remedies you use. There are no follow-up visits—the study is complete after this single appointment.
