Iron status in schizophrenic patients with acute neuroleptic-induced dystonic reactions

1. Serum iron parameters were measured in a group of schizophrenic patients who had developed acute neuroleptic-induced dystonia (N = 17) and in control patients with no history of extrapyramidal disorders (N = 16). No differences were found between the two groups for iron, ferritin or transferrin levels. 2. Iron status was estimated in 44 schizophrenic patients starting treatment with high-potency neuroleptics before and after 3 weeks of medication. In the 6 patients developing dystonia serum iron levels as well as other iron parameters did not differ from the values observed in the remaining 38 patients either on admission or after neuroleptic treatment. In each group the haematological profile was not modified by neuroleptic medication. 3. These results do not support an association between low serum iron and the occurrence of neuroleptic-induced dystonic reactions.
