Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

587
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: Modulators of Neurotransmitter Release Mediated by SV2A Protein

567
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: GABAergic Pathway Potentiators01:18

Antiepileptic Drugs: GABAergic Pathway Potentiators

868
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: Glutamate Antagonists01:14

Antiepileptic Drugs: Glutamate Antagonists

632
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

847
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

393
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:

  • Neuroscience
  • Neurology
  • Exercise Physiology

Background:

  • Epilepsy is a complex brain disorder with significant neurobiological, cognitive, psychological, and social impacts.
  • Physical inactivity can exacerbate epilepsy pathophysiology and negatively affect patient outcomes.

Purpose of the Study:

  • To review the multifaceted effects of physical exercise on epilepsy pathophysiology.
  • To explore the mechanisms through which exercise influences epilepsy.

Main Methods:

  • An extensive literature search was conducted using Scopus and PubMed.
  • Included studies were written in English and focused on the relationship between physical exercise and epilepsy.

Main Results:

  • Regular physical exercise decreases pro-inflammatory and stress biomarkers, reducing seizure incidence.
  • Exercise improves mood, reduces depression and anxiety, and enhances cognitive function in individuals with epilepsy.
  • Key neurobiological benefits include increased brain-derived neurotrophic factor (BDNF), enhanced neurogenesis, inhibited oxidative stress, and stimulated dopamine production.

Conclusions:

  • Physical exercise is a valuable non-pharmacological intervention for managing epilepsy.
  • Exercise positively impacts various aspects of epilepsy, from seizure control to cognitive and psychological well-being.
