PURPOSE To investigate the clinical, electroencephalographic (EEG), and histopathologic effects of subacute electrical stimulation of the hippocampal formation or gyrus (SAHCS) on 10 patients with intractable temporal lobe seizures. METHODS Bilateral, depth, hippocampal or unilateral, subdural, basotemporal electrodes were implanted in all 10 patients for(More)
OBJECTIVE To evaluate the efficacy of chronic electrical stimulation of centromedian thalamic nuclei (ESCM) in the treatment of difficult-to-control seizures. METHODS Thirteen patients underwent ESCM for periods ranging from 12 to 94 months (mean, 41.2 mo) with electrodes stereotactically placed in both centromedian nuclei and connected to internalized(More)
Previous reports have provided evidence of a reticulo-thalamic system, extending from the mesencephalic reticular formation (MRF) to the ventrolateral thalamus (VL), involved in the production of tremor. In humans, a funnel of fibers in the posterior subthalamus named the prelemniscal radiations (Raprl) has been described as an exquisite target to treat(More)
The present report recapitulates the clinical and electrophysiologic studies we have performed on patients with certain forms of medically intractable epilepsy to investigate the basic mechanisms and predictor factors for seizure control of the electrical stimulation of the thalamic centromedian nucleus (CM) procedure. Acute electrical stimulation of CM(More)
Incremental, desynchronizing and spike-wave electrocortical responses and concomitant symptoms to acute electrical stimulation of the centromedian thalamic nucleus (CM) were studied in 12 patients with intractable complex partial and tonic-clonic generalized seizures. Low-frequency (6/s), 320-800 microA stimulation of the caudal-basal and central portions(More)
BACKGROUND There is controversy in the literature regarding the strategy used to obtain better outcomes after performing an anterior temporal lobectomy (ATL). Some investigators prefer to reduce the risks and costs of the predictor studies despite the fact that the number of patients cured after ATL (no seizures with no medication) is relatively small.(More)
Sleep-epilepsy interactions were studied in ten patients with Lennox-Gastaut Syndrome (LGS) suffering intractable generalized tonic seizures associated with generalized ictal fast spikes and interictal slow spike-wave complexes, where electrodes were implanted in the centromedian thalamic nucleus (CM) as part of a neuroaugmentive procedure for seizure(More)
Acute high-frequency (60/s) high-intensity (2,100-2,300 microA) stimulation of the mesial, caudal and inferior portion of the centromedian thalamic region within or close to the parafascicular nucleus produced a sharp, intense, cramp-like painful response localized to the face and shoulder (medial stimulation) or arm and hand (lateral stimulation)(More)
Objectives: In the treatment of acute myocardial infarction (MI), the time delay to achieve reperfusion of the infarction-related artery has been linked to survival rates. Primary or direct angioplasty has been found to be an excellent means of achieving reperfusion in acute ST-elevation MI compared to thrombolytic therapy in randomized trials. However, no(More)
