Urinary excretion of histamine, as well as histaminuria following intravenous L-histidine loading, were studied in patients with so-called vascular headache. It was found that urinary excretion of histamine was increased on one or more occasions in 7 of 22 patients with cluster headache. The excretion was significantly higher on attack days than on attack free days. With migraine, increased excretion was found in 5 of 31 patients on days of an attack, whereas the corresponding figure for headache free days was 7 of 24 patients. Three patients showed increased histamine excretion during, as well as between, attacks. The excretion on attack days was not significantly different from that on attack free days. In cluster headache patients, L-histdine administration on attack days did not indicate that an increased histamine formation took place under such circumstances. The underlying mechanism behind the increased histamine output with cluster headache may be increased formation or liberation or altered catabolism. Histamine is more likely to be a consequence than the cause of an attack of cluster headache.

The controversial relations between migraine and vascular headache on one hand, epilepsy on the other hand are once more discussed: survey of the arguments for a more than fortuitous connexion, taken from literature and general experience. Critical analysis of the personal case material. Discussion of some specific groups of patients with various combinations of both syndromes: long antecedents of headaches, leading up to sporadic epileptic attacks, focal or generalized; clinical seizures under photic stimulation (10% of the cases with chronic headaches without organic lesions); headaches in the latency period of symptomatic epilepsy; cases of seeming transition between the two syndromes; headaches as a substitute, an aura or as a component of the epileptic seizure, with clearly distinctive features between generalized and focal epilepsy: in patients with bilateral EEG paroxysms, headaches are usually diffuse or bilateral, in those with epileptogenic foci, headaches, if consistently localized, are always reported to be homolateral to the focus. Considerations concerning pathogenesis include the familiar hypothesis of hypoxic discharges following migrainous vasoconstriction, as well as secondary vascular headaches induced by focal epileptic activity. Headaches caused by excessive discharges in the sensory representation areas (H. Jackson) must be rare. Whether increased neuronal activity in the hypothalamus may be responsible for the migraine syndrome (Herberg), possibly in connection with biogenic amines, remains in open question.

The use of cryosurgery applied to the sphenopalatine area (artery and ganglion) plus the superficial temporal and occipital branches of the external carotid artery has proven worthwhile in a majority of patients in whom this procedure has been used since 1968. Experience includes almost 700 procedures in more than 500 patients who have answered to follow-up. The procedure is not a major operation, is repeatable and, until the ideal drug is discovered, offers a better than average change for definite improvement in vascular headache.

CBF was studied in 15 cases of vascular headache by the 135Xe intra-arterial injection method. The mean CBF was found to be increased during the headache phase of the migraine attacks in half the cases, mainly due to an increase in the rapid component (CBFg). After the attack there could be an increase or a decrease of the slow component (CBFw). Reactivity to anaesthetic depression was studied in 8 migraine cases and on the whole it was found not to be much altered in most cases. Finally, no modifications of CBF were found in any of 3 cases of cluster headache who were studied during attacks of severe pain.

Carotid endarterectomy has become a widely used approach to the treatment of cerebrovascular disease. In spite of increasing experience, a significant and varied morbidity remains attached to the procedure. A poorly recognized complication is postoperative headache. In a series of 57 endarterectomies in 50 patients, 24 patients experienced postoperative headaches encompassing the entire spectrum of vascular headaches: nonspecific diffuse headaches, severe hemicranias, cluster headaches occurring early and delayed, chronic paroxysmal hemicranias, carotidynia, and Eagle's syndrome. Five patients had hemicranias, and all were homolateral to the endarterectomy. Therefore, we hypothesize that the spontaneously occurring hemicranias, the counterparts of postsurgical headache syndromes, also may be due to some overt or occult injury or disease of the carotid vessels or carotid sheaths in the regions from the carotid bifurcation to the base of the skull.

We describe seven patients with vascular headaches. Five of them had cluster headaches, which were preceded by migrainous scotamata (two patients), weakness contralateral to the pain (one), accompanied by ipsilateral photopsias (one), or by contralateral paresthesias (one). The other two patients had "clusters" of daily common migraine headaches separated by long free intervals. The symptoms of these patients suggest a common root for cluster and migraine headaches.

The dispute about whether migraine and cluster headache are one disorder--the "unified theory"--or two facets of a spectrum of "vascular headache" has not yet been settled. The author discusses various clinical features that unite or divide migraine and cluster headache in this respect: so-called "mixed forms" of vascular headache, corneal indentation pulse amplitudes, partial Horner's syndrome and possible aberrations in histamine metabolism. Evidence is presented showing that there may exist subunits of cluster headache, such as chronic paroxysmal hemicrania (C.P.H.) and a hitherto unreported type that co-exists with recurring bouts of retrobulbar neuritis and a partial factor XII deficiency.

Older people often describe their headaches as starting with vague neck discomfort and eventually moving to the temples and forehead. These are muscle-tension headaches, by far the most common type in the elderly. Although cervical osteoarthritis often is at fault, depression can be a significant factor, patricularly when headaches are chronic. There is no sure cure for tension headache, and often, several of the many remedies-ethyl chloride spray, moist heat, massage, antidepressant drugs, analgesics, local anesthetics, etc.-must be tried before an effective one is found. But just as important to successful therapy are concern, compassion, and a willingness to listen on the part of the physician. True migraine headaches are rare in the elderly. More prevalent is the type of vascular headache associated with giant cell arteritis, which is severe and resistant to any form of analgesic except the strongest narcotics. Vascular headaches also may result from congestive heart failure (which produces venous congestion in the cranial cavity), transient ischemia, increased intracranial pressure, and a variety of metabolic disturbances.

Thirty-three patients have been treated by acupuncture since July 8, 1974, using body loci, ear points and electrical stimulation. Of the 33 cases, 18 were female and 15 were male, ranging in age from 25 to 77 years. Sixteen patients suffered from migraines, 12 from tension headaches, 2 from cluster headaches, 1 from vascular headaches, and for 2 patients the etiology was uncertain. The duration of the headaches ranged from 3 months to 40 years. The patients received from 3 to 16 treatments. Of the 33 cases, 5 patients had only 3 treatments and 10 patients had 5 or less treatments. Eighteen patients had good results, i.e., no headache at all. Twelve patients had fair results, that is they sometimes had headaches, but they could be controlled with a few repetitions of treatment or by analgesics at a lesser dosage than they were taking at the beginning of treatments. Three patients had no response at all or poor results; however, these discontinued treatment before the author could evaluate whether they were actual absolute no-response cases. Of the 33 patients, 2 patients had a good response after only 2 treatments; 4 had a good response after 10 treatments. However, most of the patients had a good response after 6-8 treatments. A course of treatment usually requires 10 to 14 visits befor definite evaluation of the results can be made. It was observed that patients with fair or particularly poor results usually discontinued treatment too early and/or had concomitant conditions as well. Even though a longer period of time for follow-up is necessary before drawing any conclusions, results have already shown that acupuncture, perhaps, can be a valuable form of treatment for headaches.

Retinal hemorrhage occurred in 36% of 39 subjects exposed to altitudes at or above 14,200 feet. In subjects with a history of vascular headaches at sea level, there was a higher incidence of and more severe altitude headache, as well as a higher incidence of retinal hemorrhage than among those previously headache-free. In subjects without altitude headache, none had retinal hemorrhage. In subjects with altitude headache, 42% had retinal hemorrhage. A progressive rise in the incidence of retinal hemorrhage was correlated with progressively greater intensity of altitude headache. Factors that intensified the rate or degree of exposure, including rapid ascent and strenuous exertion, appeared to increase the likelihood of hemorrhage. An optimal balance between acclimatization and subsequent altitude stress appeared to prevent retinal hemorrhage. Increased retinal blood flow, retinal vessel engorgement, increased retinal vein and prevenous capillary pressure, and possibly decreased intraocular pressure may contribute to the pathogenesis of retinal hemorrhage.
