Arteries of the Lower Limbs01:24

Arteries of the Lower Limbs

206
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...

Antiepileptic Drugs: GABAergic Pathway Potentiators01:18

Antiepileptic Drugs: GABAergic Pathway Potentiators

446
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.
Benzodiazepines are a well-known class of drugs used for...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

332
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Antiepileptic Drugs: Glutamate Antagonists01:14

Antiepileptic Drugs: Glutamate Antagonists

407
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...

Seizures: Classification01:13

Seizures: Classification

396
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Antiepileptic Drugs: Potassium Channel Activators01:20

Antiepileptic Drugs: Potassium Channel Activators

203
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...

Area of Science:

  • Genetics
  • Neurology

Background:

  • Epilepsy is a complex neurological disorder with a significant genetic component.
  • Accurate identification of epilepsy-associated genes is crucial for understanding disease mechanisms and developing targeted therapies.

Approach:

  • A systematic search and cross-referencing of epilepsy-associated genes were performed using OMIM, HGMD, and PubMed databases up to July 2023.
  • Genes were ranked by mutation and case numbers to highlight clinically relevant genes, including those from the China Epilepsy Gene 1.0 project.

Key Points:

  • 1506 epilepsy-associated genes were identified, categorized by their association with epilepsy, neurodevelopmental disorders, or broader physical abnormalities.
  • 115 of the core epilepsy genes (68.5%) were linked to epileptic encephalopathy.
  • An additional 1440 potential epilepsy genes were identified, with 278 showing repeated variants in epilepsy patients.

Conclusions:

  • This updated gene list enhances genetic screening strategies for epilepsy.
  • It supports precise molecular diagnosis and personalized treatment approaches for individuals with epilepsy.
