Could a few weeks of 50% deet cause neurological problems in later life?

Side effects of deet: Most serious and devastating complication of large deet poisonings is neurological damage. Patients may have disorientation, clumsiness when walking, seizures, or coma. Death is possible in these cases. I do not know how long and how much of deet you use. Most common side effects are redness of skin.

No; Very unlikely: Unless you drank the stuff in huge quantities --it would be so very rare--someone would beg to study you. 1. Unlike Mercury, DEET doesn't accumulate in the body. It is gone in 24 hrs. There have been hundreds of atudies, Example:w. using it at 40ml per kg per day for 60 days straight (who volunteers for this?) Anyway, even these poor subjects were fine unless they drank lots of alcohol too..
