Your neighbor's infant daughter has epilepsy. They are considering surgery to help with the seizures, but they are worried that permanent brain damage will result. What should you tell them? At that age, the brain is "plastic," so that a different part of the brain can likely take over the functioning of the damaged area. They should carefully consider this option in that any damage will be permanent. It will be difficult to tell if there will be brain damage because infants do not really do much. They should proceed with caution in that, if there is any brain damage on the left hemisphere, their daughter might never learn to speak.
