When an EEG is used

An EEG can be used to help diagnose and monitor a number of conditions affecting the brain.

It may helpidentify the cause of certain symptoms such as seizures (fits) or memory problems or find out more about a condition you've already been diagnosed with.

The main use of an EEG is to detect andinvestigateepilepsy, a condition that causes repeated seizures. An EEGwill help your doctor identify the type of epilepsy you have, what may be triggering your seizures, and how best to treat you.

Less often, an EEG may be used to investigate other problems, such as dementia, head injuries, brain tumours,encephalitis(brain inflammation) and sleep disorders, such as obstructive sleep apnoea.
