Abstract
|
|
|
|
Epilepsy is closely related to the autonomic nervous system. Clinical manifestations of autonomic nervous system dysfunction are common in patients with epilepsy during the seizures. Also interictal autonomic dysfunction is reported. A variety of autonomic manifestation can be observed depending on the body parts. Pupils in face, cardiopulmonary function in chest, gastrointestinal function in abdomen, genitourinary function in pelvis, and skin manifestations in limbs can often be produced during the seizures. Seizure-induced autonomic dysfunction could cause serious clinical consequences, such as sudden unexpected death in epilepsy (SUDEP). Many brain stimulation studies showed that parasympathetic and sympathetic responses could be evoked by direct electrical stimulations on the limbic areas including insula, amygdala, and hypothalamus. The localization and lateralization of autonomic manifestations are difficult, except for ictal vomiting, retching, spitting and urinary urge which suggest right hemispheric onset seizure. The autonomic manifestations should not be overshadowed clinically by more apparent motor and cognitive seizures.
