Article

Psychiatric and cognitive disorders in persons with epilepsy (PWE) are often overlooked or undertreated. Studies have shown that they occur in all types of epilepsy, but they are especially prominent when epilepsy is severe and multiple antiepileptic drugs are used. In particular, the clinician should be vigilant about the coexistence of depression with epilepsy. The depression must be properly treated to improve quality of life and also to prevent the mood disorder from interfering with epilepsy treatment.

Mortality in PWE is overall twice that in the general population, but most of the increased mortality is due to major conditions with which the epilepsy is associated. The clinician should be aware that some PWE have increased risk for suicide. The phenomenon of sudden unexplained death in epilepsy occurs at the highest rate in persons with uncontrolled seizures, especially generalized convulsive seizures. For now, optimizing seizure control appears to be the best way to reduce the risk for this still mysterious and catastrophic event.
