Electroencephalogram (EEG) biofeedback, also known as neurofeedback, is a promising alternative treatment for patients with attention deficit/hyperactivity disorder (AD/HD). EEG biofeedback therapy rewards scalp EEG frequencies that are associated with relaxed attention, and suppresses frequencies associated with under- or over-arousal. In large-scale(More)
Serum prolactin levels rise after generalized tonic-clonic and partial complex seizures, but not after pseudoepileptic seizures. The criteria for a significant elevation in serum prolactin vary with individual investigators. The prevalence of pseudoseizures in the population studied determines the predictive value of serum prolactin determinations. In(More)
An abnormal flux of monovalent cations may be related to the epileptogenic process in man. One possible mechanism for deranged electrolyte metabolism in epileptic brain is an abnormality in sodium, potassium-dependent adenosine triphosphatase (Na, K ATPase). We found the activity of Na, K ATPase to be significantly less in epileptic human corfex than in(More)
We studied the distribution of valproic acid (VPA) between brain (gray matter) and serum in 13 patients receiving chronic VPA therapy who underwent cortical resections for intractable seizures. Valproate concentration in cerebral cortex was remarkably low compared with either total or unbound valproate concentration in serum. The respective brain-to-serum(More)
Anticonvulsant levels decline as pregnancy progresses, even in the face of constant and, in some cases, increased dosages of medications. It has been suggested that this decline is responsible for the increase in seizure frequency seen in approximately one-third of the women with epilepsy who become pregnant. Changes in plasma protein binding may explain(More)
We performed a retrospective study of the effect of antidepressant treatment with doxepin on seizure frequency. From 47 patients treated with doxepin in 3 years, a confirmed seizure disorder and adequate follow-up (mean, 6.8 months) were available for 19 patients. Comparison of mean monthly seizure frequency during equal blocks of time before and during(More)
The impact of the synthetic glucocorticoid prednisone on adrenal steroid hormone production was examined using 24-hour urinary steroid hormone profiling. Five women, who were chronically taking low-dose prednisone, were tested, and the relevant literature was reviewed. As expected, adrenal glucocorticoid production, measured by urinary terminal cortisol and(More)
Simultaneous brain (gray matter) and serum specimens from 18 patients treated with oral phenytoin, who underwent cortical resections for intractable seizures, were analyzed by HPLC. The correlation between brain phenytoin concentration and unbound (free) phenytoin (r = 0.98-0.99) was significantly better than the correlation between brain phenytoin and(More)
