Summary
Identifying the cause of epilepsy is crucial for diagnosis, prognosis, and treatment. This review categorizes epilepsy causes into structural, genetic, infectious, metabolic, immune, and neurodegenerative types, aiding in personalized epilepsy management.
Area of Science:
- Neurology
- Epileptology
Background:
- Accurate epilepsy diagnosis and management depend on identifying the underlying cause (aetiology).
- Understanding aetiology informs prognosis, recurrence risk assessment, and treatment strategies.
- The International League Against Epilepsy (ILAE) classification system includes structural, genetic, infectious, metabolic, and immune categories.
Purpose of the Study:
- To categorize and discuss the most important aetiologies of epilepsy.
- To provide information relevant to Level 1 and Level 2 competency-based epilepsy curriculum.
- To highlight the increasing importance of aetiology in precision medicine for epilepsy.
Main Methods:
- Categorization of epilepsy aetiologies into six groups: structural, genetic, infectious, metabolic, immune, and neurodegenerative.
- Discussion of the most clinically significant and prevalent aetiologies within each category.
- Integration of information for entry-level and proficiency-level understanding of epilepsy aetiology.
Main Results:
- Epilepsy aetiologies are classified into six main categories, with overlap acknowledged.
- Genetic factors are considered to play a role in all epilepsy cases to varying degrees.
- Neurodegenerative causes are highlighted due to their growing significance in epilepsy.
Conclusions:
- A comprehensive understanding of epilepsy aetiology is fundamental for effective patient care.
- The categorization aids in structured learning and clinical application for epilepsy specialists.
- Identifying specific aetiologies is increasingly vital for developing targeted therapies and precision medicine approaches in epilepsy management.

01:24Epilepsy and Seizures: Overview
801
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...

01:13Seizures: Classification
903
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:

01:14Antiepileptic Drugs: Glutamate Antagonists
667
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...

01:18Antiepileptic Drugs: GABAergic Pathway Potentiators
913
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
832
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...

01:20Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein
594
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...
