[Lithium salts in the treatment of cluster headache]

After analysing personal results and the data in the literature concerning the therapeutic effects of Lithium salts in cluster headache, the Authors discuss some of the pathogenetic problems related to this particular form of idiopathic headache. The results obtained seem very favourable however the therapeutic efficiency of Lithium salts, also observed in neuralgic-vasomotor syndromes (Charlin, Sluder) and in some forms of chronic headache, seems to indicate a relatively unspecific mechanism of action. The Authors suggest therefore an intervention in the stabilization of the membrane at the CNS level, with increasing efficiency of "antinociceptive" system.
