If you have migraines or a family history of migraines, a doctor trained in treating headaches (neurologist) will likely diagnose migraines based on your medical history, symptoms, and a physical and neurological examination.
Your doctor may also recommend more tests to rule out other possible causes for your pain if your condition is unusual, complex or suddenly becomes severe.
- Blood tests. Your doctor may order these to test for blood vessel problems, infections in your spinal cord or brain, and toxins in your system.
- Magnetic resonance imaging (MRI). An MRI uses a powerful magnetic field and radio waves to produce detailed images of the brain and blood vessels.
MRI scans help doctors diagnose tumors, strokes, bleeding in the brain, infections, and other brain and nervous system (neurological) conditions.
- Computerized tomography (CT) scan. A CT scan uses a series of X-rays to create detailed cross-sectional images of the brain. This helps doctors diagnose tumors, infections, brain damage, bleeding in the brain and other possible medical problems that may be causing headaches.
Spinal tap (lumbar puncture). Your doctor may recommend a spinal tap (lumbar puncture) if he or she suspects infections, bleeding in the brain or another underlying condition.
In this procedure, a thin needle is inserted between two vertebrae in the lower back to remove a sample of cerebrospinal fluid for analysis in a lab.
