Diagnosis

 

Diagnosing seizures and epilepsy is like putting the pieces of a puzzle together. The “pieces” are information from you, your healthcare team, and your test results. Explore the criteria and tools your doctors may use to diagnose you.

Knowing you’re having a seizure and diagnosing the type of seizure or epilepsy syndrome can be difficult. Even if it’s unclear whether you’ve had a seizure, you should see a doctor if you suspect, or people tell you, that there are times when you aren’t aware of what you're doing.

The doctor would try to figure out if you had a seizure and what caused it. If another medical condition, like diabetes, caused your seizure, you will need treatment for that condition. If your doctor thinks you have epilepsy, they will probably order some tests and prescribe medicine to keep you from having more seizures.

Evaluate Your Medical History

When you visit your primary care doctor or neurologist, they’ll ask lots of questions about your health and what happened before, during, and after the seizure. It’s helpful to bring along a family member or someone else who saw the seizure. That person can tell the doctor what happened, since you may have been unconscious.

Perform a Neurological Exam

If you have spells that may be seizures, your primary doctor will probably send you to see a neurologist. A neurologist is a doctor who specializes in the brain and nervous system. They will perform a complete neurological exam to find out how well your brain and the rest of your nervous system are functioning.

Receive an Electroencephalogram (EEG)

An EEG is a safe and painless test that looks for changes in your brain's electrical patterns that relate to seizures. Some abnormal patterns may occur with many different conditions, not just seizures.

Perform Brain Imaging

Brain scans refer to a CT scan, CAT scan, or MRI scan (magnetic resonance imaging). These tests look for changes in the structure of your brain, like a tumor or bleeding. Brain scans can often see changes in the way your brain developed that could lead to seizures.

Assemble Your Healthcare Team

If your doctor diagnoses you with epilepsy, it’s important to have the right healthcare team supporting you. Depending on your treatment plan, you may work with doctors who specialize in epilepsy, advanced practice nurses, psychiatrists, psychologists, and other specialists.

What if It’s Not Epilepsy?

After looking at your test results, your doctor may find that you don’t have epilepsy. You may have a medical or psychological condition that causes events that look like epilepsy seizures. In that case, your doctor will treat the condition you have instead of giving you anti-seizure medicines.
