Question: Can Migraines Cause Abnormal EEG Results?

Can migraine cause abnormal EEG?

During visual aura, either slow waves, depression of background activity amplitude or normal EEG have been reported.

The most definitely abnormal EEGs with unilateral or bilateral delta activity have been recorded during attacks of hemiplegic migraine, and during attacks of migraine with disturbed consciousness..

What can cause abnormal EEG results?

Abnormal results on an EEG test may be due to:Abnormal bleeding (hemorrhage)An abnormal structure in the brain (such as a brain tumor)Tissue death due to a blockage in blood flow (cerebral infarction)Drug or alcohol abuse.Head injury.Migraines (in some cases)Seizure disorder (such as epilepsy)More items…•

Can migraines cause damage to the brain?

Scientists have discovered that migraines may affect the long-term structure of the brain and increase the risk of brain lesions, according to a study published in the journal Neurology.

What does a normal EEG rule out?

A normal EEG does not mean that you did not have a seizure. Approximately one-half of all EEGs done for patients with seizures are interpreted as normal. Even someone who has seizures every week can have a normal EEG test. This is because the EEG only shows brain activity during the time of the test.

Why would a neurologist order an EEG?

Most EEGs are done to diagnose and monitor seizure disorders. EEGs also can identify causes of other problems, such as sleep disorders and changes in behavior. They’re sometimes used to evaluate brain activity after a severe head injury or before a heart transplant or liver transplant.

What is Migralepsy?

Migralepsy (migraine-triggered seizures) is the term used when a seizure occurs during or within 1 hour of a typical migraine aura attack. Reversible brain MRI abnormalities have been reported in a patient with migraine-triggered seizure, possibly as a consequence of supratentorial focal cerebral edema.

Can you see migraines on an EEG?

Electroencephalogram – EEG – for migraine diagnosis This test is usually only given if the migraine sufferer has seizures and epilepsy is suspected. The EEG can detect or rule out other disorders that may be causing the migraine symptoms.

Do Migraines show up on an MRI?

An MRI can’t diagnose migraines, cluster, or tension headaches, but it can help doctors rule out other medical conditions that may cause your symptoms, such as: A brain tumor. An infection in your brain, called an abscess. The buildup of fluid in the brain, called hydrocephalus.

Are migraines like small strokes?

It is possible for a headache that feels like a migraine to occur during a stroke. A migraine aura may resemble a transient ischemic attack (TIA), also called a “mini-stroke” (a temporary stroke that resolves symptoms quickly without residual or long-term disability).

When should I see a neurologist for migraines?

“Patients should see a neurologist for any headache that is disabling,” McLauchlin said. “This applies to you if you have to stop what you are doing and lie down during a headache.” If your headaches cause pain in other areas or if the pain is on only one side of the head, you may need to see a neurologist.

Can migraines cause seizure like symptoms?

In general, migraines do not cause seizures. Migraines and seizures are two different neurologic problems that have overlapping symptoms. Many of the symptoms that occur before a migraine are similar to symptoms experienced before a seizure.

What do EEG results show?

An EEG records the electrical activity of your brain via electrodes affixed to your scalp. EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other seizure disorders.

Can an EEG detect anxiety?

Increased communication between the amygdala and hippocampus appear to correlate with symptoms of depression and anxiety, in findings that may have treatment implications, new research suggests.

What is happening in your brain during a migraine?

But during a migraine, these stimuli feel like an all-out assault. The result: The brain produces an outsize reaction to the trigger, its electrical system (mis)firing on all cylinders. This electrical activity causes a change in blood flow to the brain, which in turn affects the brain’s nerves, causing pain.

Do Migraines show up on 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.
