[Importance of calcium ions and calcium antagonists in affective psychoses].

Apart from the eminent changes in the neurotransmitter systems of the central nervous system, a disturbance of the calcium ion concentration may be of significance in the pathophysiology of affective psychoses. The present paper deals with the contribution of calcium ions in the generation of affective psychoses and discusses the calcium antagonism as a new strategy in the treatment of the disease. The following topics will be described: 1. Disturbances of calcium metabolism in affective psychoses, 2. a comparison of lithium and carbamazepine effects, 3. clinical studies with organic calcium channel blockers in affective psychoses and 4. the role of calcium ions in affective psychoses.
