Predominantly neurologist will likely diagnose migraines based on your medical history, symptoms, and a physical and neurological examination. However, your doctor may want to do a brain scan to rule out other causes of headaches, such as a brain tumor or bleeding in the brain.
Below tests are helpful in diagnosing headache:
MRI: An MRI scan 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.·
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.
