Clocking Epilepsies: A Chronomodulated Strategy-Based Therapy for Rhythmic Seizures
International Journal of Molecular Sciences
|February 25, 2023
Summary
Epilepsy seizures show daily variations linked to circadian rhythms. Understanding epilepsy genetics and circadian mechanisms may lead to time-specific chronotherapy for better antiepileptic drug (AED) treatment.
Area of Science:
- Neuroscience
- Genetics
- Chronobiology
Background:
- Epilepsy is a neurological disorder marked by recurrent seizures due to abnormal neuronal activity.
- Seizure occurrence exhibits daily variations, suggesting a link to circadian rhythms.
- Circadian clock gene variants and misalignment are implicated in epilepsy pathogenesis.
Purpose of the Study:
- To review epilepsy-related genes and their classification.
- To explore the role of circadian rhythms in epilepsy.
- To propose chronomodulated strategies for treating rhythmic epilepsies.
Main Methods:
- Compiled and classified 661 epilepsy-related genes from PHGKB and OMIM databases.
- Analyzed gene functions using Gene Ontology (GO) and KEGG pathway analyses.
- Reviewed literature on circadian rhythmicity in human and animal epilepsies, and animal models.
Main Results:
- Identified and categorized epilepsy-associated genes into driver, passenger, and undetermined groups.
- Discussed potential roles of driver genes and the influence of circadian rhythms on epilepsy.
- Highlighted the utility and limitations of rodent and zebrafish models in epilepsy research.
Conclusions:
- Genetic variability impacts antiepileptic drug (AED) efficacy.
- Circadian mechanisms are crucial in epileptogenesis and seizure control.
- Chrono-modulated chronotherapy, integrating genetic, circadian, and pharmacokinetic data, offers a promising approach for rhythmic epilepsy treatment.

749
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...

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

01:13Seizures: Classification
503
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:

01:24Epilepsy and Seizures: Overview
236
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...

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

386
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...
