How We Diagnose Epilepsy
When you meet with a pediatric neurologist, we will discuss your child’s medical history and family history. Our team will also perform a thorough examination of your child’s behavior, movement and senses. Your child may also undergo tests, such as:
- An electroencephalogram (EEG), which tracks electrical signals in your child’s brain
- Continuous video EEG, which records brain activity for 24 hours or more while your child stays in the hospital
- 3T or 7T magnetic resonance imaging (MRI), which provides the detailed images of the brain using magnets and radio waves
- Computed tomography (CT), which uses X-ray images to look for structural issues in the brain that could cause seizures
- Single-photon emission CT (SPECT), an inpatient CT that uses some radiation to measure blood flow in the brain. It can show where a seizure begins in the brain and help neurosurgeons plan surgery.
- Positron emission tomography (PET), which uses a small amount of radiation to measure the activity of brain cells
- Neuropsychological testing, which can determine if seizures have affected your child’s memory, behavior or other brain functions
- Genetic testing, which checks for genetic mutations associated with seizures
Whenever possible, we’ll try to schedule testing on the same day as your doctor visit, so it’s more convenient.
