What Happens When Seizures Are Not Easily Controlled?
Approximately 30% of people with epilepsy have seizures that are difficult to control despite one or more medications. These are referred to as refractory seizures. In these situations, the first step is to make sure the diagnosis is right and that medications were used appropriately. For example, if the medication was started at a high dose and side effects were troublesome, it is possible that slower increases would be better tolerated. If seizures only occur within an hour of awakening, then a higher dose of medicine at bedtime may be more effective. Unfortunately, despite the best medical care, seizures cannot be controlled in many people and other options such as brain surgery or the vagus nerve stimulator may be worthwhile considerations.
