[Lithium therapy in Horton's neuralgia: preliminary results]

Prophylactic use of Lithium salts in patient suffering from cluster headaches has been evaluated looking at the mean number of headache attacks in one critical period and the mean weekly duration of the period itself. These two elements have been compared to those observed on other drugs treatments. Plasma Lithium monitoring has been performed weekly during the trial. Authors discuss the results reported and the hypothetic basis of them.
