Epilepsy

Definition

Epilepsy is a neurological disorder characterized by recurrent, unprovoked seizures. These seizures are caused by abnormal electrical activity in the brain.

5 Must Know Facts For Your Next Test

1. Epilepsy can be classified into focal (partial) and generalized seizures based on where they originate in the brain.
2. The underlying causes of epilepsy include genetic factors, head trauma, infections, and developmental disorders.
3. Electroencephalography (EEG) is commonly used to diagnose epilepsy by detecting abnormal electrical activity in the brain.
4. Anti-epileptic drugs (AEDs) are the primary treatment for controlling seizures in epilepsy patients.
5. Status epilepticus is a medical emergency where a person experiences prolonged or repeated seizures without regaining consciousness.
