Diagnosing Headaches
Given that nearly every adult has suffered from a headache,
diagnosing one should be the simplest thing in the world. When
you have one, you know it. But despite the obvious and easily
perceived pain, diagnosis can be a little trickier than one
might suppose.
Physicians have no general and definitive set of tests for
diagnosing headaches. If you feel it, you feel it. But no one
else can literally and directly feel your pain, so doctors have
to rely on what you report. And, when it comes to reporting
symptoms, descriptions can vary wildly.
Some people simply aren't as articulate as others in
describing what they feel. The vocabulary for describing it is
lacking to an extent as well. Calling a feeling a 'stabbing
pain' is (literally speaking) just a metaphor. In many cases,
the pain is diffuse, making it difficult to report even the
location accurately.
Another difficulty in diagnosis lies in the fact that
headaches are not all of one type.
Simple tension headaches - produced by inflamed neck or
facial muscles, constricted head blood vessels and other causes
- don't generally get diagnosed professionally at all. They're
treated with analgesics or just endured until they fade.
Migraines, on the other hand, are more intense and periodic.
Even here almost half of migraine sufferers never see a
physician for their condition.
Physicians can use some objective factors in diagnosing the
type of headache, in order to recommend a reasonable
treatment.
Even though the pain is subjective, the type of pain is
indicative of the type of headache. Migraines, for example,
often produce intense throbbing or pulsating sensations.
Ordinary tension headaches are typically more regular and
diffuse.
Migraine headaches are often accompanied by nausea and
vomiting, sensitivity to light and sound, cold extremities and
other signs that those afflicted recognize. Since they tend to
be roughly the same from one person to another, that forms an
objective group of symptoms that professionals can rely on to
form a proper diagnosis.
Cluster headaches are intense pain behind the eye, or
temple, that occur for short periods (30 min to 1.5 hours,
typically), then re-occur the next day around the same time.
This can go on for weeks. Since it's fairly regular, here again
physicians have something to go on.
In cases where the headache is the effect of some serious
underlying neurologic or other condition, such as a brain
tumor, physicians can look for those factors when headaches are
reported.
CT or MRI scans can be used to look for well-documented
brain activity patterns that can correlate the headache to the
underlying physical problem. Headaches that progressively
worsen provide doctors an additional clue. Patterns which shift
rapidly are another. In some cases an aneurysm (weakening of a
blood vessel) that is the root cause can be detected this
way.
In those cases where the headache is the result of incorrect
medication use - MOH (medication overuse headache) - physicians
have the history of the medication used to assist their
diagnoses. Medical history of another sort is helpful, too.
Migraines run in families, while cluster headaches do not.
The diagnosis of headaches is as complex as the types and
range of symptoms. But the key in all cases is to gather as
much objective information as possible, both from the patient
and clinical tests.
