Autonomic dysfunction in epilepsy and mitochondrial diseases.

The autonomic nervous system is involved and influenced in patients with epilepsy and mitochondrial diseases in a variety of complex, often multifaceted, mechanisms. Autonomic dysfunction often remains unrecognized due to a lack of attention and awareness under the prominence of other disease symptoms. Recognition of the diverse autonomic manifestations of epilepsy and mitochondrial disease would enhance early diagnosis and appropriate management, ultimately improving quality the of life and reducing morbidity and mortality in the affected patients. In this chapter, we discuss autonomic nervous system dysfunction in children with epilepsy (Part I) and mitochondrial diseases (Part II).
