Diagnosing epilepsy

Because there is no obvious sign a person has epilepsy, unless they are having a seizure, it can make diagnosing epilepsy difficult. A diagnosis is usually made after a person has had more than one epileptic seizure.

The National Institute for Health and Care Excellence (NICE) produces guidelines for treating specific health conditions, in England and Wales. If there is a possibility that you have epilepsy, NICE recommends that you are referred to a specialist, (a doctor who is trained in diagnosing and treating epilepsy) within two weeks.

How epilepsy is diagnosed

To diagnose epilepsy, doctors gather lots of different information to assess the causes of seizures.

Tests for epilepsy

Blood tests, an Electroencephalogram (EEG) and scans are used to gather information for a diagnosis. Tests on their own cannot confirm or rule out epilepsy.
