Trace elements in hair of epileptic and normal subjects

The concentrations of Ca, Mg, Zn, Fe and Cu in scalp hair of 101 epileptic patients (48 males and 53 females, average age 25 years) and 101 normal subjects (47 males and 54 females, average age 22 years) were determined by atomic absorption spectrophotometry. Mercury was also determined in some samples. The aim of this investigation was to use scalp hair as a possible indicator of trace element abnormality and to determine whether or not differences in their levels might occur due to this neurological disorder. The results showed significant differences in Fe, Cu, Mg and Zn in the hair between the two groups but no differences were observed in the levels of Ca and Hg. The high Mg and low Zn content in the hair of epileptic patients is reported as of particular interest in the investigation of this neurological disorder.
