Onset of new headache picture at 66 must be regarded with some concern. There are many disorders which hit us from middle age on which mimic Cluster but whlch can arise from non-headche disorders and, some of which, are serious.

Given the potential complexity of new headche situations at our age (I'm 77), would be important, if at all possible, to find a headache specialist.

LOCATING HEADACHE SPECIALIST
1. 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.
2. 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.

Look for "Physician Finder" search box. 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.

NEW certification program for "Headache Medicine" by the United Council for Neurologic Subspecialties, an independent, non-profit, professional medical organization.
Since this is a new program, the initial listing is limited and so it should be checked each time you have an interest in locating a headache doctor.

IF you can't locate a HA specialist:
1. AVOID pain clinics. Their professisonal training/orientation is not useful for headache.
2. If you must use a neurologist: ASK, very clearly, what their experience & taining in headache has been. It's shocking how little education this group has received in headache. Unless a doc can assure you of special training and/or experience with headache, look some more.
BUT don't try and diagnose and treat yourself!!
