    Lithium salts have been in use for the treatment of bipolar disorder for more than 50 years, but their pharmacological mode of action remains a matter of conjecture. Li+ and Mg2+ share many physicochemical properties. Not surprisingly, many reported cellular targets for Li+ action involve Mg2+-activated enzymes, which are inhibited by Li+. In this Account, we describe results from our and other laboratories that suggest that a competition mechanism between Li+ and Mg2+ ions for Mg2+-binding sites in cellular components is the underlying theme in putative mechanisms of Li+ action.
