Often, the cause of temporal lobe seizures remains unknown. However, they can be a result of:

  • Traumatic brain injury
  • Infections, such as encephalitis or meningitis, or history of such infection
  • A process that causes scarring (gliosis) in a part of the temporal lobe called the hippocampus
  • Inflammatory disorders of the brain
  • Injury due to a previous lack of oxygen
  • Blood vessel malformations in the brain
  • Stroke
  • Brain tumors
  • Genetic syndromes

During normal waking and sleeping, your brain cells produce varying electrical activity. If the electrical activity in many brain cells becomes abnormally synchronized, a convulsion or seizure may occur. If this happens in just one area of the brain, the result is a partial seizure. When this occurs in an area of the brain known as the temporal lobe, it's called a temporal lobe seizure.
