THE CHALLENGE OF PREDICTING RESPONSE TO STABILIZING LITHIUM TREATMENT - THE IMPORTANCE OF PATIENT SELECTION

Lithium treatment, an approach with well documented efficacy, has recently been losing its treatment value. Lithium continues working, however, for those patients for whom it was proven efficacious; that is, most patients with primary episodic affective disorders. Such responders to lithium prophylaxis can be reliably identified beforehand by a comprehensive clinical assessment. The explanation for the paradox of lithium's lost efficacy lies mostly in the educational bias against a comprehensive patient assessment, and in the shift in diagnostic fashion favouring affective disorders and the treatment methods associated with them in the clinicians' minds.
