Gary Miller’s lab at Emory was the launching pad for this studyÂ from Rutgers, published last week in the FASEB Journal, showing a potentialÂ connection between a common type of insecticideÂ used at home and in agriculture, pyrethroids, and attention deficit hyperactivity disorder (ADHD).Â
*Mice exposed toÂ deltamethrin, in utero and before weaning, display changes in behavior and memory that look sorta like ADHD. The exposure levels were lower than the EPA’s developmental “no observable effect” limit. Deltamethrin appears to hit dopamine transporter function.
*NHANES data shows a connection betweenÂ pyrethroid levels in the urine and ADHD diagnosis. Detectable pyrethroid metabolites meant the risk of ADHD diagnosis was up 2.3-fold.
The lead author from Rutgers, former Emory postdoc Jason Richardson, also recently published research on a connection between DTT and Alzheimer’s diseaseÂ with Emory neurology researchers.
*Mice â‰ Â humans.
*Another study of pyrethroids and ADHD didn’t find a strong statistical connection.
