Leroux E, Ducros A.

ABSTRACT: Cluster headache (CH) is a primary headache disease characterized by recurrent short-lasting attacks (15 to 180 minutes) of excruciating unilateral periorbital pain accompanied by ipsilateral autonomic signs (lacrimation, nasal congestion, ptosis, miosis, lid edema, redness of the eye). It affects young adults, predominantly males. Prevalence is estimated at 0.5-1.0/1,000. CH has a circannual and circadian periodicity, attacks being clustered (hence the name) in bouts that can occur during specific months of the year. ALCOHOL IS THE ONLY DIETARY TRIGGER OF CH, STRONG ODORS (MAINLY SOLVENTS AND CIGARETTE SMOKE) AND NAPPING MAY ALSO TRIGGER CH ATTACKS. During bouts, attacks may happen at precise hours, especially during the night. During the attacks, patients tend to be restless. CH may be episodic or chronic, depending on the presence of remission periods. CH IS ASSOCIATED WITH TRIGEMINOVASCULAR ACTIVATION AND NEUROENDOCRINE AND VEGETATIVE DISTURBANCES, HOWEVER, THE PRECISE CAUSATIVE MECHANISMS REMAIN UNKNOWN. Involvement of the hypothalamus (a structure regulating endocrine function and sleep-wake rhythms) has been confirmed, explaining, at least in part, the cyclic aspects of CH. The disease is familial in about 10% of cases. Genetic factors play a role in CH susceptibility, and a causative role has been suggested for the hypocretin receptor gene. Diagnosis is clinical. Differential diagnoses include other primary headache diseases such as migraine, paroxysmal hemicrania and SUNCT syndrome. At present, there is no curative treatment. There are efficient treatments to shorten the painful attacks (acute treatments) and to reduce the number of daily attacks (prophylactic treatments). Acute treatment is based on subcutaneous administration of sumatriptan and high-flow oxygen. Verapamil, lithium, methysergide, prednisone, greater occipital nerve blocks and topiramate may be used for prophylaxis. In refractory cases, deep-brain stimulation of the hypothalamus and greater occipital nerve stimulators have been tried in experimental settings.THE DISEASE COURSE OVER A LIFETIME IS UNPREDICTABLE. Some patients have only one period of attacks, while in others the disease evolves from episodic to chronic form.

If all this says Cluster, then seek a HEADACHE specialist, not just any doc/neurologist.

LOCATING HEADACHE SPECIALIST

1. Search the OUCH site (button on left) for a list of recommended M.D.s.

2. Yellow Pages phone book: look for "Headache Clinics" in the M.D. section and look under "neurologist" where some docs will list speciality areas of practice.

3.  Call your hospital/medical center. They often have an office to assist in finding a physician. You may have to ask for the social worker/patient advocate.

5. Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to or Look for "Physician Finder" search box.  Call 1-800-643-5552; they will send a list of M.D.s for your state.I suggest using this source for several reasons: first, we have read several messages from people who, even seeing neurologists, are unhappy with the quality of care and ATTITUDES they have encountered; second, the clinical director of the Jefferson (Philadelphia) Headache Clinic said, in late 1999, that upwards of 40%+ of U.S. doctors have poor training in treating headache and/or hold attitudes about headache ("hysterical female disorder") which block them from sympathetic and effective work with the patient; third, it's necessary to find a doctor who has experience, skill, and a set of attitudes which give hope of success. This is the best method I know of to find such a physician.

The suicide spike through the eye, and the waking up at 2 AM with 30 min. attacks sound like CH to me.

The lying down in a dark room (for light sensitivity?) maybe not so much, but apparently there are all kinds of headache types and variants, and there's this "cluster migraine" thing that I don't know much about.

I'm no medical professional, but if you go to one to get a good diagnosis, please make sure it's a reputable headache specialist, and even then you have to educate yourself plenty, because fat chance any doctor is going to prescribe (at least not without being prompted) what is for many the very most effective treatment for CH.

I'm talking about hi flow/non rebreather O2. More info at the "oxygen info" button on the left. Please reply here though if those left hand buttons aren't visible in your view.

There are conditions that can cause headaches that can be very serious.

You didn't mention having had an MRI to rule out anything more serious.  You need to do that. 

It is very important that you get a correct diagnosis, because using the wrong meds for your condition can prove deadly in some cases.

Please demand to be seen by a Headache Specialist Neurologist.  You need to get to the heart of the matter.
