The mean level of aluminum was significantly higher in cases compared to the control (20.79±10.2, 7.85±1 respectively with P<0.0001). Mean level of mercury among cases was significantly higher than among controls (1.24±1.12, 0.22±0.147 respectively). Cases also had significantly higher levels of lead compared to controls but they were within the normal levels.
