Epilepsy

Epilepsy is a condition characterised by recurrent, unprovoked seizures, or a high probability (>60 per cent) of seizure recurrence following a single seizure (Fisher et al., 2014). Most neurological conditions (MS, AD, etc.) are unified by a common underlying process within the brain, giving rise to a number of symptoms. Epilepsy is different in that the diagnosis is conferred on the basis of the defining symptom, seizures. The abnormalities and pathologies that can result in seizures are multiple and varied and may be structurally apparent or cryptogenic, genetic or acquired (Berg et al., 2010). This makes epilepsy both the most common neurological disorder worldwide and the most common neurological comorbidity of other neurological conditions. It follows that people with epilepsy form an extremely heterogeneous population
