Its basically a seizure and thats why seizure medicine is what helps. Its calming down the visual cortex in the brain which has been over stimulated. The problem is we are calming down the whole brain with seizure medicine. We need to target the visual cortex specifically. I think Stereotactic radiosurgery (SRS) or Laser Interstitial Thermal Therapy (LITT) or something similar could work. Does anyone know any neuro surgeons that has worked on people suffering from epilepsy and other seizures?

What is thermal ablation for epilepsy?

Thermal ablation is also called laser interstitial thermal therapy or LITT procedure. It is a less invasive surgery for carefully selected people with epilepsy. It does not involve opening the bone covering the brain.

• LITT uses laser technology to deliver a set amount of energy to a specific brain region.
• The laser energy changes into thermal or heat energy. This can remove or destroy the brain cells causing the seizures (commonly called seizure focus).
• MRI (magnetic resonance imaging) is used during the procedure to monitor the heat so it targets the correct area of the brain to be "ablated" or removed.
• A computer program marks the temperature where the probe is placed. This helps protect the brain tissue around the seizure focus.
• The procedure can remove a seizure focus with pinpoint accuracy.
• There is only a small amount of discomfort after the procedure.
• People only stay in the hospital one or two days after it.

High-intensity focused ultrasound

High-intensity focused ultrasound is one of the new approaches to thalamotomy that is being used for patients who have refractory ET or refractory tremors of PD. This procedure, which hundreds of patients have already experienced, relies on the thermal energy of ultrasound, guided by MRI, to achieve non-invasive thalamic ablation.
