caffeine/seizures

Postnatal caffeine treatment of rats can influence brain excitability during development. To study the mechanism involved in the alterations of seizure susceptibility, we used an animal model that corresponds to the infants treated with caffeine for apnea of prematurity. Seizure susceptibility to

During a course of ECT, seizure duration may become too brief for clinical benefit. Use of higher-energy stimuli may lengthen seizures but may also increase the risk of toxicity, and it is not possible when maximum settings are reached. The authors present the cases of six drug-free depressed

Two strains of inbred mice differed significantly in their susceptibility to tonic seizures induced by caffeine and the benzodiazepine inverse agonist, methyl 6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate (DMCM). The hyporesponsive strain, SWR, was not less susceptible to the convulsant action

BACKGROUND Postnatal treatment with caffeine from P7 to P11 (10 or 20 mg/kg daily) resulted in transient changes in two pentylenetetrazole (PTZ)-induced models of epileptic seizures characterized by spike-and-wave EEG rhythm in immature rats. To know if some changes persist into adulthood we studied

Caffeine has been used clinically to increase seizure length in electroconvulsive treatment (ECT). The present study was designed to establish an animal model of caffeine-augmented seizures for further study of mechanisms and effects of pharmacological manipulation of seizure length. Increasing

Rats were kindled during exposure to caffeine (50 mg/kg) or saline given IP twenty minutes before daily electrical stimulation of the amygdala until 3 kindled amygdaloid seizures (KAS) occurred. They were then stimulated for 3 days without drug pretreatment followed by 5 additional days with drug

Caffeine-augmented electroconvulsive therapy has been introduced into medical practice without experimental confirmation that such seizure modification does not result in neuronal injury. In this report rats pretreated with caffeine prior to a series of nine electrically induced convulsions showed

The concentration and time dependence of caffeine-induced neurotoxicity was determined by infusing rats intravenously with caffeine at a rate of about 5, 12.5, and 25 mg kg-1 min-1 until the onset of generalized seizures which occurred at about 82, 28, and 11 min, respectively. The concentration of

The effects of phencyclidine (PCP) on the threshold and intensity of caffeine-induced convulsions in rats were examined. There was a dose-dependent effect of PCP on convulsion intensity with significant reduction in intensity at 4.0 and 8.0 mg/kg PCP. At 16.0 mg/kg PCP, convulsant intensity was

A 45-year-old female migraineur with a long-standing history of drug-induced headache is described. She had been abusing caffeine (250 mg/day) and aspirin (5 gr/day). On the third day after discontinuation a withdrawal syndrome characterized by headache and a generalized tonic-clonic seizure

A 27-year-old parturient developed a severe headache after placement of a labor epidural catheter. A presumptive diagnosis of an occult postdural puncture headache (PDPH) was made, and the patient was treated with an intravenous (IV) infusion of 500 mg of caffeine sodium benzoate (CSB) to

The Electroconvulsive Therapy is a widely used technique in psychiatry as a treatment for several mental disorders with particular indications. To produce therapeutic effect it's necessary to induce a convulsion which is considered adequate if its duration lasts more than 20 seconds. Considerations

The neurological tottering mutant mouse is characterized by frequent "absence" seizures accompanied by bilateral synchronous spike and wave EEG bursts. Under anesthesia, adult homozygous tottering mice were implanted with permanent epidural electrodes, and at least 7 days elapsed before

Neonatal DBA/2J, 101/HY and CBA/Lac/Sto mice (2-7-day-old) were subcutaneously injected with caffeine (200 mg/kg), piracetam (50 mg/kg) or distilled water. At the age of 1 month, they were tested for audiogenic seizure susceptibility (SS). The neonatal injections changed SS in 1-month-old mice in a

Repeated caffeine treatment during early postnatal period led to a decreased sensitivity to convulsant action of drugs interfering with inhibitory systems. To know if it is a general effect we studied convulsant action of agonists of glutamate receptors N-methyl-d-aspartate (NMDA) and kainic acid
