Hypnic headache syndrome is a benign, recurrent, late-onset headache disorder that occurs exclusively during sleep. Lithium has been reported to be an effective treatment, but the side effects of this medication are sometimes prohibitive, particularly in the elderly. Other drugs have been reported to be effective in this disorder, including caffeine, flunarizine, and verapamil. Recently, indomethacin has been reported to effectively suppress hypnic headaches. We report the response of seven patients with hypnic headache who were treated with indomethacin. Hypnic headache syndrome appears to represent yet another headache disorder in which there is sometimes an impressive response to indomethacin.

Cluster headache is an uncommon yet well-defined neurovascular syndrome occurring in both episodic and chronic varieties. The most striking feature of cluster headache is the unmistakable circadian and circannual periodicity. Inheritance may play a role in some families. The attacks are of extreme intensity, of short duration, occur unilaterally, and are accompanied by signs and symptoms of autonomic dysfunction. In contrast to migraine, during an attack the cluster patient prefers to pace about. Attacks frequently occur at night. Although the pathophysiology of cluster headache remains to be fully elucidated, several seminal observations have recently been made. The medical treatment of cluster headache includes both acute therapy aimed at aborting individual attacks and prophylactic therapy aimed at preventing recurrent attacks during the cluster period. Agents used for acute therapy include inhalation of oxygen, sumatriptan, and dihydroergotamine. Transitional prophylaxis involves the short-term use of either corticosteroids or ergotamine derivatives. The cornerstone of maintenance prophylaxis is verapamil, yet methysergide, lithium, and divalproex sodium may also be employed. In some patients, melatonin or topiramate may be useful adjunctive therapies.

Occipital condyle syndrome is a rare, but stereotypic syndrome. Early detection has important therapeutic implications. Evaluation of the craniovertebral junction with special attention to the occipital condyles should be a routine part of all brain and cervical spine radiologic examinations, and the possibility of occipital condyle syndrome, particularly when patients have persistent occipital pain and a history of cancer, should be considered.
