Wilkinson, David, Holmes, Clive, Woolford, Janet, Stammers, Susan and North, Janine (2002) Prophylactic therapy with lithium in elderly patients with unipolar major depression. International Journal of Geriatric Psychiatry, 17 (7), 619-622. (doi:10.1002/gps.671).

Abstract

Objectives: to compare the relapse rate of elderly depressed patients taking low dose lithium as an additional therapy with antidepressant medication to those receiving antidepressant medication alone.
Methods: fifty elderly subjects recovering from a major depressive illness taking continuation antidepressants were randomised, in a double blind study, to receive additional lithium carbonate or placebo and followed up over a two year period for evidence of relapse.
Results: relapse rate was significantly greater in those subjects taking antidepressant medication alone compared to subjects taking additional lithium therapy. After six months four (17%) subjects taking antidepressant medication alone had relapsed, whereas none of the subjects taking additional lithium had relapsed. After two years eight (33%) subjects taking antidepressant medication alone had relapsed, whereas only one (4%) of the subjects taking additional lithium had relapsed.
Conclusion: this preliminary study suggests that long-term low dose lithium therapy is well tolerated and protects elderly patients from a relapse of depressive illness.
