A 63-year-old man sat down in my office last spring and said something that always makes me slow down: “I’ve never been a headache person. Now I have one almost every day.”
Here is the short answer, because it matters more than anything else in this article. A headache that begins for the first time after age 50 is a different clinical problem than a headache that began at 25. Most of them still turn out to be benign. But the share that comes from an underlying cause rises sharply with age, and a few of those causes are both treatable and time-sensitive — meaning the window to prevent permanent damage is measured in days, not months. So the right response is neither reassurance nor alarm. It is a short, specific workup that takes one visit and a blood draw.
Why age changes the arithmetic
Migraine and tension-type headache — the two conditions responsible for the overwhelming majority of headaches — almost always announce themselves earlier in life. Migraine typically begins in the teens, twenties, or thirties. It is uncommon, though not impossible, for genuine migraine to make its first appearance in someone’s sixth decade. Tension-type headache behaves similarly.
So when a person who has gone fifty or sixty years without meaningful headaches suddenly develops them, the statistical baseline that protects younger patients no longer applies. In younger adults, secondary headache — pain caused by something else — accounts for only a small percentage of cases. In older adults presenting with new headache, published series put that figure considerably higher, often cited in the range of ten to fifteen percent. That is still a minority. But it is a large enough minority that “let’s watch it for a few months” is the wrong plan.
Age itself is formally listed as a red flag in the SNNOOP10 criteria that headache specialists use to decide who needs investigation. “Older age” — meaning new or progressive headache beginning after 50 — sits on that list alongside sudden thunderclap onset, neurological deficits, and papilledema. It earns its place there on the strength of a single diagnosis, which I’ll come to next.
The diagnoses I rule out before anything else
Giant cell arteritis is the one I think about within the first minute. It is an inflammation of medium and large arteries that essentially does not occur before 50, becomes more common with each decade after, and can cause irreversible blindness — sometimes within days of the first visual symptom, sometimes in both eyes. The classic picture is a new temporal or scalp headache, tenderness when brushing the hair or resting the head on a pillow, jaw ache while chewing that eases with rest, and general malaise. Not every patient has all of these; some have almost none. If the suspicion is real, I order an ESR and CRP the same day, and if the clinical picture is convincing I start corticosteroids before the biopsy or imaging comes back. The eye does not wait for confirmation. I’ve written in more detail about how this presents and how it’s confirmed in Temporal Arteritis: A Headache You Can’t Ignore.
Chronic subdural hematoma is the second. Slow venous bleeding over the surface of the brain, often from a head bump the patient genuinely does not remember, sometimes from no identifiable trauma at all. It is disproportionately a disease of older adults, and anyone on an anticoagulant or antiplatelet drug is at meaningfully higher risk. The headache is usually dull, progressive over weeks, and may come with subtle personality change, unsteadiness, or word-finding trouble that a spouse notices before the patient does. CT finds it.
Medications are the third, and this is the cause most often missed because nobody thinks to look. Nitrates, PDE5 inhibitors, dipyridamole, calcium channel blockers, and several newer antihypertensives all cause headache directly. If a new daily headache began within a few weeks of a new prescription, that timeline is a finding, not a coincidence. I ask every patient over 50 to bring the actual bottles.
Acute angle-closure glaucoma deserves mention because it is routinely mistaken for migraine in the emergency department. Severe pain around one eye, a red eye, blurred vision, halos around lights, nausea and vomiting — and a hard, tender globe. It is an ophthalmologic emergency.
Beyond these, I consider untreated obstructive sleep apnea in anyone with morning headaches and daytime somnolence, cervical spine disease, and — much less often than patients fear — an intracranial mass. Which brings up the imaging question: a normal scan does not close the case. It rules out specific structural problems and nothing more. I’ve explained that distinction at length in Normal MRI but Still Headaches?
When it really is a primary headache — just an unfamiliar one
Some genuinely benign headache disorders start late in life, and recognizing them saves patients years of unnecessary worry.
Hypnic headache is the clearest example. It begins almost exclusively after 50, wakes the patient from sleep at roughly the same hour night after night, lasts anywhere from fifteen minutes to a few hours, and — unlike cluster headache — is usually a moderate, diffuse ache without the dramatic autonomic features. It responds to caffeine at bedtime, of all things, and to indomethacin or lithium in resistant cases. The full picture is in Hypnic Headache: The Headache That Wakes You.
The other pattern worth knowing is what neurologists call late-life migraine accompaniments: visual disturbances, numbness, or speech trouble arriving in a slow march over minutes, with little or no headache afterward. In someone over 50 this is understandably frightening, and it looks enough like a transient ischemic attack that it must be evaluated as one the first time. Only after a stroke workup is clean does the pattern get attributed to migraine physiology in an aging brain.
What a competent visit for this actually includes
If you are over 50 with a headache that is new, or an old headache that has clearly changed character, the visit should produce four things. A careful history of onset and trajectory — the shape of the timeline matters more than the severity. A physical exam that includes blood pressure, palpation of the temporal arteries, and a look at the optic discs. ESR and CRP if there is any suggestion of arteritis. And neuroimaging, with MRI preferred over CT for anything that isn’t an acute emergency.
Treatment also changes after 50, and this is where I see well-intentioned prescribing go wrong. Triptans are contraindicated in established coronary artery disease, cerebrovascular disease, and uncontrolled hypertension — conditions that become common in exactly this age group. NSAIDs carry more weight against aging kidneys and a stomach that may already be on an anticoagulant. Amitriptyline, a reasonable preventive at 35, brings anticholinergic burden, orthostatic drops, and falls risk at 70. Propranolol interacts with the cardiology regimen many of these patients are already on. None of this means older patients can’t be treated well. It means the drug order is different, and gepants and CGRP antibodies have moved higher on my list for this group than they were five years ago.
The mistake I see most often is not a missed tumor. It is a new headache after 50 that gets labelled “tension” or “stress,” treated with a rotating supply of over-the-counter painkillers, and returned to me two years later as a daily headache with a medication-overuse problem layered on top of whatever started it. If your headache isn’t improving, the reason is usually that it hasn’t been correctly named yet — a pattern I’ve described in Why Your Headache Isn’t Getting Better.
The man I mentioned at the start had an ESR of 78 and jaw pain he had attributed to a dental problem. He started prednisone that afternoon. His vision is intact.
