The Na,K-ATPase hypothesis for manic-depression. II. The mechanism of action of lithium.
A model as to how lithium may work in the treatment and prevention of manic-depression is presented. Lithium accumulates intracellularly, and accumulates preferentially in more active neurons. Intracellular accumulation of lithium displaces intracellular sodium, which, in turn, decreases intracellular calcium. A decrease of intracellular calcium normalizes neuron activity in both mania and depression. This model is supported by the majority of clinical and experimental data.
