How is epilepsy diagnosed? Since different types of seizures respond to different treatments, your doctor will ask about family history and request several tests.

Diagnosis

This outline will help prepare you to discuss your seizures with a doctor.

Tests

This test tracks electrical signals from the brain.

There are a number of blood tests that may be recommended as part of your epilepsy diagnosis and treatment.

A positron emission tomography (PET) scan may be used to locate the part of the brain that is causing seizures.

One test for epilepsy is a spinal tap -- also called a lumbar puncture -- a procedure in which the fluid surrounding the spinal cord (called the cerebrospinal fluid or CSF) is withdrawn through a needle and examined in a lab.
