On referral to a centre specialising in epilepsy surgery, an individual will undergo an initial consultation followed by a full evaluation. This will involve several different types of EEG, usually to document seizures, as well as several types of scan aiming to find the area of brain that is responsible for seizures.

Individuals will also undergo a full assessment of learning. This may also involve further types of scan. This is to determine whether an individual has any problems with memory, speech or learning, and to see whether any of these may be at risk from surgery.

An individual may also meet with a neuropsychiatrist to determine what they may hope for from surgery, as well as determine any problems they may have with mood.

The whole epilepsy surgery team then discusses all the results of the investigations to determine whether surgery can be offered without causing further problems. The team will then meet the individual and their family to outline the results, the surgery to be offered, the likely benefits, as well as possible risks. It will then be for the individual and/or their family to decide whether they wish to go ahead.
