Electroconvulsive Seizures in Rats and Fractionation of Their Hippocampi to Examine Seizure-induced Changes in Postsynaptic Density Proteins
Published on: August 15, 2017
Summary
Ketamine anesthesia did not trigger or worsen seizures in epileptic patients. Natural sleep was more likely to activate epileptic discharges than ketamine in this study.
Area of Science:
- Anesthesiology
- Neurology
- Epilepsy Research
Background:
- Ketamine is a rapid-acting anesthetic agent.
- The effects of anesthetics on seizure activity require thorough investigation.
- Epileptic discharges can be influenced by various physiological states.
Purpose of the Study:
- To evaluate the impact of ketamine on clinical seizures and electroencephalograms (EEGs) in epileptic patients.
- To compare ketamine's effect on epileptic discharges with alert and sleep states.
Main Methods:
- Intravenous administration of ketamine to 26 epileptic patients.
- Comparison of EEG data during ketamine anesthesia, alert state, and natural sleep.
- Monitoring for clinical seizures and epileptic discharges on EEGs.
Main Results:
- Epileptic discharges were observed in 65% of patients during the alert state.
- Sleep precipitated or aggravated epileptic discharges in 58% of patients.
- Ketamine precipitated or aggravated discharges in 31% of patients, with no seizures recorded during anesthesia.
Conclusions:
- Ketamine does not precipitate or aggravate seizures in epileptic individuals.
- Ketamine is less effective than natural sleep in activating epileptic discharges.
- Ketamine may be a viable anesthetic option for patients with epilepsy, showing a lower activation of epileptic discharges compared to sleep.

01:24Epilepsy and Seizures: Overview
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

01:18Antiepileptic Drugs: GABAergic Pathway Potentiators
γ-aminobutyric acid or GABA, plays a pivotal role as an inhibitory neurotransmitter in the brain. GABA pathway potentiators, also known as GABAergic drugs, are a class of pharmaceutical agents designed to enhance the functioning of the GABAergic system. These medications primarily treat epilepsy, a neurological disorder characterized by recurrent seizures.
The key GABA pathway potentiators used in epilepsy management are as follows.

01:17Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers, a class of antiepileptic drugs, regulate the flow of calcium ions within neurons.
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...

01:14Antiepileptic Drugs: Glutamate Antagonists
Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...
01:20Antiepileptic Drugs: Potassium Channel Activators
Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.

01:30Electroconvulsive Therapy
Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early years,...
