Other tests associated with cluster headachesIf your health professional is not able to diagnose
cluster headaches based solely on your symptoms and
physical examination, other tests may be ordered to rule out other conditions.
In addition to imaging tests (such as an
MRI or
CT scan), these tests may include: - Blood and urine tests. Blood tests may be done
to determine whether you have conditions associated with cycles of headaches
such as low thyroid function (hypothyroidism) or inflammation of
blood vessels in the temple (giant cell
arteritis).
- Electroencephalogram (EEG). This test
may be useful for people who have seizures associated with their headaches.
However, it is not often used, because other tests provide more helpful
information about the causes of headaches.
- Lumbar
puncture (spinal tap). This test is done only if there is a serious
question about your diagnosis. It is done when you have a fever and a stiff
neck to rule out
meningitis, an infection around the brain and spinal
cord.
