Epilepsy: Epidemiology, Molecular Pathogenesis, and Clinical Management

Area of Science:

• Neurology
• Neuroscience
• Epilepsy Research

Background:

• Epilepsy is a prevalent neurological disorder with significant global impact.
• A substantial portion of patients (nearly one-third) exhibit resistance to current antiseizure medications.
• Gaps persist in understanding the fundamental processes of epileptogenesis and epilepsy progression.

Purpose of the Study:

• To review epidemiological data, seizure patterns, and pathogenic mechanisms underlying epilepsy.
• To explore how recent mechanistic insights are transforming clinical management strategies.
• To highlight emerging therapeutic avenues and data-driven tools for personalized epilepsy care.

Main Methods:

• Review of epidemiological evidence and time-dependent seizure patterns.
• Analysis of pathogenic mechanisms including genetic, cellular, and network alterations.
• Synthesis of current and emerging clinical management strategies and therapeutic approaches.

Main Results:

• Identified converging pathogenic mechanisms (genetic, ion-channel, synaptic, inflammatory, metabolic, structural, network, epigenetic) that destabilize neural circuits.
• Detailed the interaction of these processes across disease stages, leading to persistent hyperexcitability.
• Summarized advancements in precision diagnostics, pharmacotherapy, surgery, neuromodulation, dietary interventions, chronotherapy, and novel disease-modifying treatments.

Conclusions:

• Current evidence advocates a paradigm shift from empirical seizure suppression to mechanism-guided, individualized epilepsy care.
• Future progress hinges on integrating molecular discoveries, validated biomarkers, and real-world implementation for earlier and potentially disease-modifying treatments.
• Emphasizes the need for equitable access to advanced diagnostic and therapeutic strategies for all epilepsy patients.
