Hello, That is a difficult question to answer without having more information. Typically a person does not just start having seizures without a reason, especially later in life without a history of having seizures. It would suggest that something happened during surgery such as lack of oxygen to the brain and stroke. I m not exactly sure what the doctors mean when they say that her brain is not responding to her body , but typically just two grand mal seizures should not cause any significant problems in the brain, unless she was having what are known as sub-clinical seizures in which she was still having seizures but was not having any externally observable movements - if that continues for a prolonged period it can begin cause damage. The answer really depends on whether there has been brain damage, and how extensive it is. Two seizures in and of themselves does not. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Janne Nissinen, Neurologist
