Abstract Background It is unknown if medications used to treat bipolar disorder have effects on brain activation and whether or not any such changes are mood-independent. Methods Patients with bipolar disorder who were depressed n 5 or euthymic n 5 were examined using fMRI before and 14 days after being started on lithium as monotherapy in 6 of these patients . Patients were examined using a word generation task and verbal memory task both of which have been shown to be sensitive to change in previous fMRI studies. Differences in blood oxygenated level dependent BOLD magnitude between the pre- and post-lithium results were determined in .
