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
