What tests are used to diagnose migraines?

Tests for Diagnosing Headaches

  • Blood chemistry and urinalysis. These tests may determine many medical conditions, including diabetes, thyroid problems, and infections, which can cause headaches.
  • CT scan.
  • MRI.
  • Sinus X-ray.
  • EEG.
  • Eye exam.
  • Spinal tap.

Can you see hemiplegic migraine on MRI?

Hemiplegic migraine attacks can manifest from temporary hemiparesis to recurrent coma and prolonged hemiparesis, epilepsy, or mental retardation. MRI abnormalities could only be detected in a few cases depending on the scan timing.

Do migraines show up on a CT scan?

Imaging tests rarely help. Health care providers see many patients for headaches and most of them have migraines or headaches caused by tension. Both kinds of headaches can be very painful, but a CT scan or an MRI rarely shows why the headache occurs. Having a CT scan or MRI also does not help ease the pain.

How rare is a hemiplegic migraine?

A migraine is a common disorder occurring in 15% to 20% of the population. Hemiplegic migraine is a rare condition, with a reported prevalence of 0.01%. A study done in Denmark indicated the prevalence of sporadic hemiplegic migraine is 0.002% and familial hemiplegic migraine is 0.003%.

How can you tell if you have hemiplegic migraine?

Hemiplegic migraine can be hard to tell apart from other conditions, like stroke or mini-stroke (also called transient ischemic attack ). Its symptoms can also be similar to diseases like multiple sclerosis or epilepsy. To rule out conditions with similar symptoms, your doctor will do tests like these:

Is there a test to tell if you have a migraine?

Diagnosis – Migraine. There’s no specific test to diagnose migraines. For an accurate diagnosis to be made, a GP must identify a pattern of recurring headaches along with the associated symptoms. Migraines can be unpredictable, sometimes occurring without the other symptoms.

Is there a genetic test for alternating hemiplegic migraine?

Test Performance. The Blueprint Genetics migraine panel covers classical genes associated with familial hemiplegic migraine and alternating hemiplegia of childhood. The genes on the panel have been carefully selected based on scientific literature, mutation databases and our experience.

What kind of Doctor do you see for hemiplegic migraine?

Treatment of hemiplegic migraine can be challenging. The care of a headache specialist is often required, as many other doctors may never have treated a case of hemiplegic migraine.

Is there a genetic test for hemiplegic migraine?

Mutations of these genes result in over-excitability of nerves. Genetic testing is available but not necessary for all people. Genetic testing may be of highest yield in people with early onset hemiplegic migraine associated with eye movement abnormalities (nystagmus), seizures or other persistent neurologic symptoms (ataxia).

How are blood tests used to diagnose migraines?

Chemistry screen This type of blood test measures the levels of substances in your blood. This can be used to determine if there is an imbalanced which may cause migraine-like symptoms. Depending on the migraine symptoms you experience, your doctor may recommend other tests to diagnose your condition.

What to do if you have hemiplegic migraine?

Imaging studies and other testing should be performed to rule out other causes of the symptoms. It is important that people with hemiplegic migraine understand their migraines as well as possible. With continuing research, especially genetic research, more is being learned about hemiplegic migraine.

When does a hemiplegic migraine start in childhood?

Both familial and sporadic hemiplegic migraines often begin in childhood. Diagnosing hemiplegic migraine can be difficult, as the symptoms can mimic stroke, seizures or other conditions.
