Objective: To estimate the efficacy of the lithium in patients with nocturnal headache and on awakening, or nightmares, or both. Method: All the fifty three patients with headache upon awakening and nightmares (50 with nocturnal headache and three with diurnal headache) were treated with lithium. The dosage used was from 150 to 900 mg at bedtime. Results: From 53 patients, 14 (26.4%) were males and 39 (73.6%) were females, ages varying from 11 to 76 years. In these 50 patients with nocturnal headache and on awakening, 35 (70.0%) there was cessation; 10 (20.0%) frequency and intensity diminished and five (10.0%) presented no improvement after lithium administration. In 11 patients with nightmares, nine (81.8%) there was cessation; one (9.1%) frequency and intensity diminished and one (9.1%) no improvement with the treatment. Conclusion: The lithium is an efficient drug in the treatment of the nocturnal headache and on awakening and also in the nightmares.
