Mesial Temporal Sclerosis

What Is Mesial Temporal Sclerosis?
Take Action
Causes and Symptoms of Mesial Temporal Sclerosis

Sometimes a lack of oxygen, an infection, trauma or continuing seizures contribute to the development of mesial temporal sclerosis. But the cause is not always known.

Symptoms of mesial temporal sclerosis are generally associated with focal (partial) epilepsy, such as

  • muscle spasms or convulsions
  • behavioral changes
  • strange sensations such as seeing auras or
  • seizures
Diagnosis of Mesial Temporal Sclerosis

An optimized high-resolution MRI, like the ones we use at our epilepsy centers in the NY area, can show mesial temporal sclerosis that other general MRIs often miss.

Medical scans such as PET (positron emission tomography) scans or SPECT (single-photon emission computed tomography) scans and electroencephalograms (EEGs) can help determine where the sclerosis is and where the seizures originate.

Surgical Treatments for Mesial Temporal Sclerosis

Mesial temporal sclerosis treatments generally consist of managing the epilepsy symptom by using either anticonvulsant medication or, if medication is not effective, surgery.

Surgical treatments for intractable epilepsy include a temporal lobectomy or vagal nerve stimulation.

Temporal lobectomy is a surgical procedure to remove the brain tissue in the temporal lobe that is causing the seizures. An amygdalohippocampectomy is the surgical removal of the amygdala and the hippocampus after other treatments have failed to provide relief. Neuroimaging allows our expert brain surgeons to carefully target the damaged tissue and allow as much healthy brain tissue to remain as possible.

Additional Treatments

Vagal Nerve Stimulation is a minimally invasive mesial temporal sclerosis treatment that employs an implanted stimulator to deliver electric impulses to an electrode on the vagal nerve in the neck via a lead wire implanted under the skin. These impulses modulate the brain’s circuitry.

The revolutionary NeuroPace RNS® System uses a pacemaker, similar to ones used in deep brain stimulation to treat Parkinson’s disease, to employ electrial stimulation to normalize brain activity.
