=====Cluster tic syndrome=====
The term "cluster-tic syndrome" is used for the rare ipsilateral co-occurrence of attacks of cluster headache and [[trigeminal neuralgia]]. Medical treatment should combine treatment for cluster headache and trigeminal neuralgia, but is very often unsatisfactory.

A 41-year-old woman diagnosed with cluster-tic syndrome who underwent microvascular decompression of the trigeminal nerve, primarily aimed at the "trigeminal neuralgia" part of her pain syndrome. After venous decompression of the trigeminal nerve both a decrease in trigeminal neuralgia and cluster headache attacks was seen. However, the headache did not disappear completely. Furthermore, she reported a decrease in pain intensity of the remaining cluster headache attacks.

This case description suggests that venous vascular decompression in cluster-tic syndrome can be remarkably effective, both for trigeminal neuralgia and cluster headache
