In some cases, when drug therapy fails to control severity and recurrence of seizures, the doctor may look for other options. Surgery is only indicated in some cases where the origin of the seizure, for example a lesion, is located to be a very precise section of the brain. Certain diagnostic investigations are carried out to ascertain the feasibility of surgery. It is essential that the benefit outweighs the risk.
After identifying the local cause of seizures, it can be surgically removed, keeping the surrounding area intact. It is essential to ascertain that the surgical target tissue is not a control area for movements integral functions, or senses.
Another approach which deals with the localized cause of seizure is to spare the surgical removal of the area, but controlling the seizures by cutting the connection between the origin and its conduction pathway of neurons.
Both these approaches are highly invasive. Surgery requires a lot of pre-evaluation. In an initial phase, the investigative procedures are carried out to find the location of the target tissue, and also evaluating the feasibility of the procedure, and any possible risk factors associated with the surgery.
