Partial (focal) seizure

Jacksonian seizure; Seizure - partial (focal); Temporal lobe seizure; Epilepsy - partial seizures; Partial (focal) seizure

All seizures are caused by abnormal electrical disturbances in the brain. Focal seizures occur when this electrical activity is in a limited area of the brain. Sometimes the seizures stay only in one part of the brain, while at other times, the seizures can turn into bilateral tonic-clonic seizures, which affect the whole brain. This is called secondary generalization.

Focal seizures can be divided into whether they affect awareness or not:

  • Focal, aware
  • Focal, awareness impaired

Focal seizures are also classified by whether they are motor (movements with the seizures) or not.


The major areas of the brain have one or more specific functions.
