A number of essential trace elements play a major role in various metabolic pathways and in many diseases like autoimmune,
neurological and psychiatric. This study is undertaken with an aim to evaluate the levels of different trace elements in the
scalp hair samples of patients suffering from alcohol induced psychosis by particle induced X-ray emission technique (PIXE).
It is observed that Fe (p < 0.0005), Cu (p < 0.001) are significantly higher in the hair samples of alcohol induced psychosis patients compared to those in normals
while concentrations of Mn (p < 0.005) and Zn (p < 0.0001) are lower. The concentrations of Co and Ni in the hair samples are found to be in consonance with the concentrations
in the normals.
