Abstract

Background: The effectiveness of lithium is being questioned increasingly and requires clarification. Aims: To assess the effectiveness of lithium treatment in depression and mania, syndromal types I and II, with predominantly mixed or psychotic episodes or rapid cycling, during treatment resumed following discontinuation, and across three decades. Method: The longitudinal course of 360 patients with bipolar disorder compliant with lithium treatment for at least 1 year and without comorbidity for substance use disorder was reviewed. Results: Risk of single-episode recurrences, a common index of treatment failure, was similar to that in other reports. Both episode frequency and ‘time ill’ improved more in type II than type I cases. Reduced morbidity during treatment was similar in patients with mixed or psychotic episodes, or rapid cycling, and in less complex cases. Retreatment yielded minor decrements in response, and there was no tendency for lesser responses in more recent years. Conclusions: Based on overall affective morbidity, long-term lithium treatment in compliant patients without comorbid substance use disorder, though imperfect, remains effective, even in subgroups of supposedly poor prognosis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
