Epilepsy natural history, complications and prognosis

If left untreated, 23% to 71% of patients with a single unprovoked seizure may experience it again within 2 years. After the second unprovoked seizure, the chance of having another seizure increase to 73%. Recurrent seizures with no underlying illness emphasis on epilepsy diagnosis. Common complications of epilepsy include: Status epilepticus, sudden unexpected death, submersion Injury, dental injury, burns, fractures, head injury, soft tissue injury and motor vehicle accidents.

• Recurrent seizures with no underlying illness emphasis on epilepsy diagnosis.

• In contrast to adolescent onset epilepsy syndromes most of the childhood onset epilepsy such as benign childhood epilepsy with centrotemporal spikes will go to remission.
• There is no evidence demonstrating the effect of medical therapy on natural history of epilepsy.^[1]
