If your doctor suspects you have epilepsy, you are not alone. According to the Centers for Disease Control and Prevention (CDC),\u00a0over 3 million people<\/a>\u00a0live with epilepsy in the United States. Anyone can have epilepsy, regardless of age or background, and it is one of the most common types of nervous system disorders.<\/p>\n Epilepsy is a general term used to describe a brain condition that causes recurring seizures. There are many different causes of epilepsy and various types of seizures.<\/p>\n A seizure can happen whenever something interrupts the normal signals between nerve cells in the brain. For example, a high fever or withdrawal from alcohol can cause anyone to have a seizure. However, when a person has two or more seizures not caused by a temporary medical condition, they may be diagnosed with epilepsy.<\/p>\n According to the Mayo Clinic, epilepsy has no known cause\u00a0in about half of the people<\/a>\u00a0with the disorder. In others, epilepsy may stem from the following factors:<\/p>\n The symptoms of epilepsy depend on the type of seizure a person experiences. Typically, medical professionals classify seizures as either focal or generalized.<\/p>\n Doctors call a seizure a focal if it appears to occur from activity in one part of your brain. Focal seizures may happen while you’re still aware. Symptoms of a focal seizure without a loss of consciousness include:<\/p>\n A focal seizure can also occur with impaired awareness. During this type of seizure, you might stare off into space and not notice your surroundings normally. You might also engage in a repetitive movement with impaired awareness, such as walking in circles or rubbing your hands.<\/p>\n Generalized seizures seem to affect the whole brain. There are six types of generalized seizures, which are:<\/p>\n Doctors do not have a single test to diagnose epilepsy. Instead, they must combine several tests to evaluate your condition and provide an accurate diagnosis.<\/p>\n Typically, your doctor will first review your medical history and symptoms. Next, they may perform a neurological exam to assess your mental functioning. They might also order blood work to check for infections or another condition that may cause seizures.<\/p>\n After their initial evaluation, your doctor might recommend a specialized test such as an\u00a0electroencephalogram (EEG) or\u00a0brain scan to detect unusual activity or characteristics in your brain.<\/p>\n It’s important doctors determine the type of seizures you experience and where in the brain they occur. This allows them to choose an effective treatment for your condition.<\/p>\n A brain scan for seizures creates detailed images of your brain. The images help doctors pinpoint the cause of your seizures. There are three main types of brain scans used to diagnose epilepsy. These include:<\/p>\n A doctor might order a\u00a0CT scan<\/a>\u00a0for a seizure diagnosis. A CT scan, sometimes called a cat scan, uses\u00a0x-ray<\/a>\u00a0beams to produce cross-sectional images of your brain. Unlike an x-ray machine, a CT scanner creates highly detailed images of soft tissues, such as the brain.<\/p>\n During a CT scan, you’ll lie on an exam table. This table moves into a short tunnel where a scanner will rotate around you and emit x-ray beams. The machine measures the amount of x-rays your body absorbs. This information is then processed by a computer to create images.<\/p>\n Your doctor can view your CT scan results and look for abnormalities in your brain that may be causing seizures, such as tumors or cysts. This will help your doctor take the next step in treating the root problem of the seizures you’re experiencing.<\/p>\n Doctors may prefer an\u00a0MRI<\/a>\u00a0for seizure evaluation in non-emergency situations. An MRI machine has a large, tubular shape. During an MRI, you’ll lie on a table that slides into the opening of the scanner. The MRI machine will use a strong magnet and radio waves to send signals from your body to a computer. The computer will then analyze the signals and produce detailed images of your brain. The doctor views these images on a monitor and looks for lesions or abnormal characteristics in your brain to help them determine the cause of your seizures.<\/p>\n A\u00a0PET scan<\/a>\u00a0is a type of nuclear medicine imaging. A PET scan uses a small amount of radioactive material and a special scanner to create images of your brain. During a PET scan, you’ll receive a tiny amount of radioactive material, called a tracer, by injection. After the injection, you’ll lie on an exam table and move into a scanner. The PET scan will detect the radioactive tracer in your body and send the information to a computer. The computer will then turn the data into three-dimensional images for your doctor to view on a monitor.<\/p>\n PET scans are often used to detect and monitor cancer. However, they can also be helpful in evaluating the brain and finding abnormal functioning.<\/p>\n If your doctor suggests an MRI or CT scan for seizures, you may feel a little overwhelmed. Undergoing any medical procedure can seem intimidating, especially if you aren’t feeling well. However, an imaging test will help your doctor determine the proper diagnosis, so they can help you get the treatment you need.<\/p>\n If you live in the Denver area, know that we’re here to help you.
