In this study, we present the results obtained from a series of patients with refractory temporal lobe epilepsy (r-TLE) who underwent hippocampal deep brain stimulation (Hip-DBS). ⋯ Although performed on a relatively small number of patients, Hip-DBS was safe and effective in our patients with r-TLE. Seven of the nine patients were considered responders. Hip-DBS might represent a useful therapeutic option in patients with refractory temporal lobe epilepsy who were not candidates for resective surgery or have had previous failed procedures.

A new leucine-rich glioma-inactivated 1 gene (LGI1) mutation inducing an amino acid sequence substitution was found in a Korean family with autosomal dominant lateral temporal lobe epilepsy (ADLTE). We report the clinical features and characteristics of this newly identified LGI1 mutation. ⋯ We identified a new LGI1 mutation in a large Korean ADLTE family which appeared to be involved in the development of epilepsy through suppressing LGI1 protein secretion.

Status epilepticus has been increasingly associated with cardiac injury in both clinical and animal studies. Our group has previously shown that excitotoxic seizure induction results in the formation of ischaemic myocardial infarcts and loss of cardiac haemodynamic function. We hypothesised that attenuation of cardiac sympathetic/parasympathetic balance with a central presynaptic α₂ agonist, clonidine, can reduce the development of interictal ECG and ventricular morphological changes resulting from kainic acid (KA; 10mg/kg) induced status epilepticus in a conscious rat model. ⋯ These results demonstrate that KA-induced seizures are associated with altered ECG activity and cardiac structural pathology. We suggest that pharmacological modulation of sympathetic/parasympathetic activity in status epilepticus provides a promising therapeutic approach to reduce seizure-induced cardiomyopathy.

Predicting seizure control after epilepsy surgery is difficult. The objectives of this work are: (a) to estimate the value of surgical procedure, presence of neuroimaging abnormalities, need for intracranial recordings, resection lobe, pathology, durations of epilepsy and follow-up period to predict postsurgical seizure control after epilepsy surgery and (b) to provide empirical estimates of successful outcome after different combinations of the above factors in order to aid clinicians in advising patients presurgically about the likelihood of success under their patients' individual circumstances. ⋯ Overall, nearly 70% of patients undergoing resective surgery enjoy favourable post-surgical seizure control. Normal neuroimaging should not discourage surgery in temporal patients but is a negative prognostic sign in normal MRI frontal patients. There were no statistical differences in outcome between patients with neuroimaging lesions in frontal or temporal lobes.

There are different possible temporal associations between epileptic seizures and headache attacks which have given rise to unclear or controversial terminologies. The classification of the International League Against Epilepsy does not refer to this type of disorder, while the International Classification of Headache Disorders (ICHD-2) defines three kinds of association: (1) migraine-triggered seizure ("migralepsy"), (2) hemicrania epileptica, and (3) post-ictal headache. ⋯ On the basis of this review we suggest definitions and a terminology which may become the basis of a forthcoming classification of headaches associated with epileptic seizures.
