1. Bipolar disorder is typically a chronic disease entailing an episodes co
urse, whereby psychiatric status alternates between periods of normal funct
ioning and periods of illness. Lithium is well established and approved for
the treatment of bipolar disorder. However, its efficacy in practice is no
t as great as expected. This retrospective record study was undertaken to d
etermine the efficacy of lithium in bipolar disorders.
2. 48 patients who met DSM-III-R diagnostic criteria for bipolar I disorder
and had been admitted once before lithium therapy and twice or more after
that, were included in this study.
3. No significant difference in length between episode (frequency) was obse
rved before and after lithium maintenance therapy. In addition, the percent
ages of manic episode after Lithium therapy were much greater than before t
hat.
4. The results indicate that it is worth re-examining the efficacy of lithi
um in bipolar disorders.
