Relief of cluster-tic syndrome by the combination of lithium and carbamazepine.

This paper presents a further case of cluster-tic syndrome. Cluster headache and trigeminal neuralgia have coexisted in our patient for 18 years. Carbamazepine has selectively relieved the tic douloureux, while lithium has completely controlled the cluster headache. Our case shows again that the simultaneous occurrence of cluster headache and trigeminal neuralgia seems to be more than coincidental.
