Epilepsy is a neurological disorder where there are recurrent bursts of abnormal brain activity, causing seizures or periods of unusual behaviour, sensations and sometimes loss of awareness.

Once the diagnosis of epilepsy has been established, its treatment must be individualised. This includes the need for treatment and choice of Anti-Epileptic Drugs (AED). The benefits of treatment (such as reducing the risk of seizure recurrences or injuries self and others) must be weighted against the drawbacks of treatment which include potential drug side effects, cost and inconvenience.
