EPILEPSY SURGERY

Epilepsy surgery

Epilepsy is a chronic condition presenting with seizures. A seizure is defined as uncontrollable, temporary activation of a section of brain cortex spreading to whole or part of the brain. Normally in the brain different sections are working simultaneously and activation is counterbalanced by suppression. Loss of balance in a particular section of the brain leads to over activation of that area which is called epileptic focus. The epileptic focus tends to get overly activated from time to time and this activation may spread to neighbour areas and so on. Sometimes the activation may spread to the whole brain – in this situation the patients experience the generalized seizure. If the activation is restricted to a part of the brain the patient has a partial seizure. The main difference between generalized and partial seizures is loss of consciousness. Partial seizures do not cause loss of consciousness. There many conditions that can cause epilepsy. Brain tumor, bleeding, ischemia, hydrocephalus, developmental issues, medications, toxins, infections and many other conditions can cause seizures. usu
