Partial (focal) seizureFocal seizure; Jacksonian seizure; Seizure - partial (focal); Temporal lobe seizure; Epilepsy - partial seizures
All seizures are caused by abnormal electrical disturbances in the brain. Partial (focal) seizures occur when this electrical activity remains in a limited area of the brain. The seizures can sometimes turn into generalized seizures, which affect the whole brain. This is called secondary generalization.
Partial seizures can be divided into:
- Simple, not affecting awareness or memory
- Complex, affecting awareness or memory of events before, during, and immediately after the seizure, and affecting behavior
