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 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
- 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 partial seizure that originates in one of the temporal lobes.
