Abstract Background It has been suggested that lithium increases choline concentrations although previous human studies examining this possibility using 1H magnetic resonance spectroscopy 1H MRS have had mixed results some found increases while most found no differences. Methods The present study utilized 1H MRS in a 3 T scanner to examine the effects of both lithium and sodium valproate upon choline concentrations in treated euthymic bipolar patients utilizing two different methodologies. In the first part of the study healthy controls n 18 were compared with euthymic Bipolar Disorder patients Type I and Type II who were taking either lithium n 14 or sodium .
