Partial (Focal) Seizures

Partial (focal) seizures refer to seizures beginning in one area of the brain. By observing which area of the body is affected by the seizure, physicians can identify where in the brain the seizure occurred. 

Partial seizures are further categorized as either:

• Simple partial seizures – The seizure is localized to one area on one side of the brain, but may spread to other areas. Consciousness is not lost during a simple partial seizure.
• Complex partial seizures – Seizures originating in one area of the brain that affect consciousness are labeled as complex partial seizures.
• Partial seizures that secondarily generalize – Partial seizures may spread to other areas of the brain.
