This paper discusses essential issues related to long-term lithium therapy and presents a case of successful 50-year lithium treatment. Lithium is currently regarded as the drug of choice for preventing manic and depressive recurrences in bipolar disorder. In 1/3 of patients with bipolar disorder, long-term monotherapy with lithium can completely prevent recurrences of abnormal mood. Numerous clinical and psychosocial factors associated with a good response to lithium have been described. Lithium is more efficacious than other mood stabilizers, and its long-term treatment significantly exceeds them. Lithium also exerts antisuicidal, immunomodulatory, and neuroprotective effects. The main problems associated with long-term lithium treatment include kidney, thyroid, and probably cognitive issues. In this paper, a case of successful continuous lithium treatment for 50 years in a 79-year-old female patient is presented. In this patient, apart from maintaining a euthymic state, long-term lithium treatment also exerted a favorable effect on general health, especially the elimination of viral and other respiratory infections. It is concluded that ultra-long term lithium therapy can enable good professional and psychosocial functioning for many patients, and the possible somatic side effects are manageable.
