Focal seizures are divided into simple or complex based on the level of consciousness during an attack. Simple partial seizures occur in patients who are conscious, whereas complex partial seizures demonstrate impaired levels of consciousness.

The first thing doctors always try is medication. If that fails to control your seizures there are a couple of more options depending on wether your seizures are focal or generalized. There is the vagus nerve stimulator (VNS) for focal seizures. If that fails, the last alternative is surgery. Surgery best treats focal seizures, but can also treat generalized seizures. If you are a qualifying candidate for surgery, it will either decrease or eliminate sezure activity.

There is temporal lobe epilepsy (which is the most common), frontal lobe epilepsy, parietal lobe epilepsy, and occipital lobe epilepsy. however, seizures are catagorized into two catagories: focal seizures and generalized seizures.

The most common type of surgery is the focal cortical resection. In this procedure, a small part of the brain responsible for causing the seizures is removed.

Signs and symptoms of CNS involvement can include polyuria, polydipsia, obesity, impotence, amenorrhea, confusion/amnesia (short and long term memory), meningitis, and seizures (focal seizures).
