Effects of Psychotropic Drugs on Seizure Threshold

Drug Safety, 2002
Psychotropic drugs, especially antidepressants and antipsychotics, may give rise to some concern in clinical practice because of their known ability to reduce seizure threshold and to provoke epileptic seizures. Although the phenomenon has been described with almost all the available compounds, neither its real magnitude nor the seizurogenic potential ...

l-Theanine intake increases threshold for limbic seizures but decreases threshold for generalized seizures

Nutritional Neuroscience, 2013
L-Theanine, an ethylamide derivate of glutamate found in abundance in green tea, has been shown to exert beneficial actions in animal models for several neurological disorders. We here investigated for the first time the effect of L-theanine intake on seizure susceptibility using acute pilocarpine and pentylenetetrazol (PTZ) mouse models for studying ...

Electroconvulsive Therapy and the Seizure Threshold^*

The Canadian Journal of Psychiatry, 1983
The use of a pulsatile square wave stimulus for a large series of electroconvulsive treatments under conditions of routine clinical practice is compared to the equivalent experience with a sine wave stimulus. The literature indicates that both waveforms are equally effective convulsants. However, in this series, the induction of a convulsion was found

Change in Seizure Threshold During Electroconvulsive Therapy

The Journal of ECT, 2008
The seizure threshold (ST) is a measure of the minimum electrical energy necessary to induce a grand mal seizure. Dose titration of the ST has been suggested to optimize stimulus dosing in electroconvulsive therapy (ECT). The change in ST with remission is examined in a large sample of unipolar depressed patients.In a study of continuation treatments ...

Seizure threshold in ECT: I. Initial seizure threshold.

Journal of the Medical Association of Thailand = Chotmaihet thangphaet, 2000
Seizure threshold determination is of crucial importance in optimizing electrical stimulus dosage during administering electroconvulsive therapy (ECT). We measured initial seizure threshold by means of Srinakharinwirot University titration schedule in 150 psychotic patients.

Nitrous oxide elevates local anesthetic seizure threshold

Experimental Neurology, 1972
Abstract The median intravenous convulsant dose (CD50) of lidocaine in awake unoperated cats breathing air was 7.65 mg/kg. In acute experiments on cats ventilated with nitrous oxide and having noninvasive extradural cortical recording electrodes, the lidocaine CD50 was 11.43 mg/kg—an elevation of the CD50 in air-breathing animals of nearly 50%.

Strain Differences in Picrotoxin Seizure Threshold

Nature, 1962
THE purpose of this work was to compare the seizure thresholds of two genetically different strains of rats. Rosenzweig, Krech and Bennett1 have shown that the descendants of Tryon's2 maze brights (S1's) are superior in learning ability to the descendants of Tryon's maze dulls (S3's) and that the S1's have higher levels of cerebral cortical ...

Does Iron Deficiency Raise the Seizure Threshold?

Journal of Child Neurology, 1995
To determine the effect of iron status on the seizure threshold, measures of iron sufficiency were prospectively evaluated in 51 children presenting to a pediatric emergency department with a febrile illness with (26) or without (25) an associated febrile seizure.

Seizure thresholds and their postictal changes in audiogenic seizure (AGS)-susceptible rats

European Journal of Pharmacology, 1984
The convulsive thresholds for bicuculline and electroshock seizures were studied in audiogenic seizure (AGS)-susceptible and control rats. Electroshock seizure thresholds, determined as the amperage necessary to cause tonic extension of the hindlegs in 50% of the rats (CC50 = convulsive current fifty) were markedly lowered in rats of two stocks, bred ...
