Lithium carbonate therapy for cluster headache. Changes in number of platelets, and serotonin and histamine levels.
Three groups of patients were studied: Group A consisted of 12 patients with cluster headache that was treated with lithium carbonate. Group B consisted of six patients with cluster headache that was managed with other drugs. Group C consisted of five patients with muscle contraction headache who received lithium. Serum lithium levels, platelet count, platelet serotonin levels, and platelet-rich plasma histamine levels were determined before and during therapy. The frequency of the headache and levels of serotonin and histamine tended to follow a parallel course in groups A and B: as the headache frequency dropped, serotonin and histamine levels fell. The stable period was characterized by little change in serotonin and histamine levels. Recurrences of headaches were accompanied by a return of serotonin and histamine to pretreatment levels. The course of cluster headache is related to changes in serotonin and histamine levels. Lithium, by modifying the headache course, changes serotonin and histamine levels.
