Epilepsy (0)

Epilepsy (from the Ancient Greek ἐπιληψία epilēpsía) is a common chronic neurological disorder characterized by recurrent unprovoked seizures.[1][2] These seizures are transient signs and/or symptoms of abnormal, excessive or synchronous neuronal activity in the brain.[3] About 50 million people worldwide have epilepsy, with almost 90% of these people being in developing countries.[4] Epilepsy is more likely to occur in young children, or people over the age of 65 years, however it can occur at any time.[5] Epilepsy is usually controlled, but not cured, with medication, although surgery may be considered in difficult cases. However, over 30% of people with epilepsy do not have seizure control even with the best available medications.[6][7] Not all epilepsy syndromes are lifelong – some forms are confined to particular stages of childhood. Epilepsy should not be understood as a single disorder, but rather as syndromic with vastly divergent symptoms but all involving episodic abnormal electrical activity in the brain.
