Cluster-tic syndrome.

A case of cluster-tic syndrome is presented. A 51-year-old man developed pain attacks corresponding to the second branch of the trigeminal nerve. After treatment with 1200 mg carbamazepine daily, the attacks disappeared. Full remission was achieved, and carbamazepine therapy was continued. Pain attacks of a quite different character then appeared; their clinical picture corresponded to cluster headache. After treatment with cyproheptadine, the cluster headache attacks ceased, but 2 days later, before the discontinuation of the treatment, the attacks of trigeminal neuralgia reappeared. Treatment with carbamazepine was started again, and there was remission of the trigeminal neuralgia after several weeks.
