Tests and diagnosis

By Mayo Clinic Staff

Your doctor will ask for a detailed description of the seizures and conduct a physical exam. Tests may include:

  • Electroencephalography (EEG). This painless procedure measures waves of electrical activity in the brain. Brain waves are transmitted to the EEG machine via small electrodes attached to the scalp with paste or an elastic cap.

    Your child may be asked to breathe rapidly or look at flickering lights, an attempt to provoke a seizure. During a seizure, the pattern on the EEG differs from the normal pattern.

  • Brain scans. Tests such as magnetic resonance imaging (MRI) can produce detailed images of the brain, which can help rule out other problems, such as a stroke or a brain tumor. Because your child will need to hold still for long periods, talk with your doctor about the possible use of sedation.
