Epilepsy research

Sudden unexplained death is an important cause of mortality in patients with epilepsy and cause for this is not fully understood. One of the explanations is autonomic dysfunction (AD). Studies of AD in chronic refractory epilepsy are very few in the literature. ⋯ This is the first study from India to evaluate autonomic functions in refractory epilepsy patients. Autonomic dysfunction was noted in 56.3% of patients. Anticonvulsants used were not associated with AD. Longitudinal controlled studies with 'newly diagnosed' epilepsy patients will enhance further understanding about the role of autonomic system in epilepsy.
