Tian ma, an ancient Chinese herb, offers new options for the treatment of epilepsy and other conditions.

Our purpose is to bring attention to the antiepileptic properties of the Chinese herb tian ma and its constituents, as well as to suggest the potential for the development of new antiepileptic drugs (AEDs) related to this herb. All available literature regarding the chemistry, pharmacology, animal data, and clinical use of tian ma and its constituents are reviewed, showing that tian ma, its constituents, and its symbiotic fungus Armillaria mellea have antiepileptic properties in in vitro and in vivo models. One clinical study reportedly demonstrated the AED effects of a component of tian ma, vanillin.

Effect of vagus nerve stimulation on adults with pharmacoresistant generalized epilepsy syndromes.

Introduction: Although vagus nerve stimulation (VNS) therapy is approved for the treatment of partial onset seizures, its efficacy for generalized seizures has not been fully evaluated. This Investigational Device Exemption assessed the outcome of VNS therapy among patients with generalized epilepsy syndromes.

Methods: Sixteen patients with pharmacoresistant generalized epilepsy syndromes and stable antiepileptic drug (AED) regimens were implanted with the VNS therapy device and were evaluated for changes in seizure frequency and type between baseline and follow-up of 12-21 months.

Language Disturbances as Side Effects of Topiramate and Zonisamide Therapy.

Reversible side effects of two sulfa-containing antiepileptic drugs (AEDs), topiramate (TPM) and zonisamide (ZNS), are reported. These effects differ from those of other AEDs in that language impairment was the predominant cognitive complaint. Information was available for 42 patients exposed to TPM.

Evidence That Emotional Maladjustment Is Worse in Men Than in Women with Psychogenic Nonepileptic Seizures.

The purpose of this study is to examine the effects of gender on adjustment and cognition in patients with psychogenic nonepileptic seizures (NES) and on patients with epilepsy. We compared 57 women and 27 men, all at least 16 years old, with only NES as documented by long-term EEG-video monitor studies, to equal numbers of randomly selected women and men with only epileptic seizures. Variables examined included age, age of onset, education, scales from the MMPI, the WAIS-R, and the number of tests outside normal limits from the Neuropsychological Battery for Epilepsy.

Serum and CSF glutamine levels in valproate-related hyperammonemic encephalopathy.

Purpose: To investigate ammonia and glutamine levels in valproate (VPA)-related hyperammonemic encephalopathy (VHE).

Methods: We reviewed the medical records and EEG recordings of seven adults diagnosed with VHE.

Results: Venous ammonia levels were elevated in five (71%) of the seven patients.
