Causes

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

• Traumatic brain injury
• Infections, such as encephalitis or meningitis, or a history of such infections
• A process that causes scarring (gliosis) in a part of the temporal lobe called the hippocampus
• 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 focal seizure. A temporal lobe seizure is a focal seizure that originates in one of the temporal lobes.
