Epilepsy Currents
|November 25, 2020
Summary
Persistent sodium current (INaP) plays a key role in epilepsy. This review highlights recent findings on INaP and novel anti-seizure medications targeting this persistent current.
Area of Science:
- Neuroscience
- Channelopathies
- Epilepsy Research
Background:
- Voltage-gated sodium channels (VGSCs) are crucial for action potential generation and propagation in excitable cells.
- A small persistent sodium current (INaP) flows even during prolonged depolarization, contributing to normal neuronal function.
- Elevated INaP is increasingly recognized as a pathogenic factor in epilepsy.
Purpose of the Study:
- To review recent evidence on the role of INaP in epilepsy.
- To explore novel anti-seizure medication strategies that preferentially target INaP.
Main Methods:
- Literature review of recent advances in epilepsy research.
- Analysis of the role of INaP in sodium channelopathies.
- Identification of emerging therapeutic strategies targeting INaP.
Main Results:
- Accumulating evidence supports a significant role of elevated INaP in the pathophysiology of epilepsy.
- Advances in understanding INaP have opened new avenues for therapeutic intervention.
- Preferential targeting of INaP represents a promising strategy for novel anti-seizure medications.
Conclusions:
- INaP is a critical target for developing new epilepsy treatments.
- Future research should focus on developing selective INaP inhibitors for epilepsy management.
- Targeting INaP offers a promising approach to combatting sodium channelopathies associated with epilepsy.

1.3K
Antiepileptic drugs are specialized medications that prevent seizures in individuals diagnosed with epilepsy. These drugs primarily function by blocking the movement of sodium ions through channels in the neuronal membrane, inhibiting the repetitive firing of action potentials often associated with seizures.
Sodium channel blockers modulate ion channels, particularly voltage-gated sodium channels. They block only sodium ion movement.
Among the most commonly prescribed antiepileptic drugs are...

01:19The Role of Ion Channels in Neuronal Computation
3.5K
A postsynaptic neuron usually receives numerous impulses from several other presynaptic neurons. The axon hillock of the postsynaptic neuron integrates all these signals and determines the likelihood of firing an action potential.
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....

01:24Epilepsy and Seizures: Overview
920
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...

01:17Antiepileptic Drugs: Calcium Channel Blockers
915
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...

457
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.
Ezogabine has gained approval as an adjunctive treatment...

9.6K
Voltage-gated ion channels are transmembrane proteins that open and close in response to changes in the membrane potential. They are present on the membranes of all electrically excitable cells such as neurons, heart, and muscle cells.
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several...
