Subjects and methods: Plasma from 102 autistic individuals, and 18 neurotypical controls, were tested for plasma zinc and copper using inductively-coupled plasma-mass spectrometry. Copper and zinc levels and Cu/Zn were analyzed for possible correlation with severity of 19 symptoms. Results: Autistic individuals had elevated plasma levels of copper and Cu/Zn and lower, but not significantly lower, plasma Zn compared to neurotypical controls. There was a correlation between Cu/Zn and expressive language, receptive language, focus attention, hyperactivity, fine motor skills, gross motor skills and Tip Toeing. There was a negative correlation between plasma zinc concentration and hyperactivity, and fine motor skills severity. Discussion: These results suggest an association between plasma Cu/Zn and severity of symptoms associated with autism. %U http://www.la-press.com/plasma-copper-and-zinc-concentration-in-individuals-with-autism-correl-article-a3076
