 Therapeutic strategies to restore network stability in epilepsy.

Therapeutic logicMain target/mechanismWhat it aims to stabilizePotential strengthsKey limitations/challengesTranslational status
Restoring inhibitory balanceEnhancement of GABAergic signaling, strengthening inhibitory restraint, improving receptor-mediated inhibition, increasing synaptic inhibitory toneExcitation–inhibition balance, seizure threshold, circuit containment of abnormal firingConceptually directed, clinically familiar, and often effective for acute seizure control or symptomatic suppressionMay not correct upstream glial, inflammatory, calcium-linked, or remodeling mechanisms; efficacy can vary across syndromes and chronic stages; tolerance or incomplete disease modification may limit long-term impactEstablished clinical strategy for seizure control, but often insufficient alone for durable modification of epileptogenic instability [41, 252]
Modulating astrocyte dysfunctionImproving potassium buffering, glutamate uptake, water regulation, metabolic support, and limiting maladaptive astrocyte reactivityExtracellular homeostasis, neurotransmitter balance, ionic stability, propagation permissiveness, recovery capacityMechanistically attractive because astrocytes regulate the extracellular conditions that directly shape excitability and seizure spreadTherapeutic targeting remains biologically complex; astrocyte responses are context dependent; restoring homeostatic function without disrupting adaptive support is challengingEmerging and largely preclinical/translational, with strong conceptual rationale but limited clinical implementation [14, 83, 234]
Modulating microglial dysfunctionLimiting maladaptive inflammatory activation, altering cytokine release, reducing harmful synaptic remodeling, and reshaping context-dependent microglial responsesInflammatory amplification, maladaptive synaptic/environmental signaling, chronic seizure-prone tissue statesMay interrupt feedback loops between tissue stress, immune signaling, glial activation, and progressive destabilizationMicroglia can be protective, maladaptive, or mixed depending on timing and context; indiscriminate suppression may be counterproductiveEmerging and mechanistically promising, but still limited by context specificity and incomplete translational precision [241, 243]
Targeting calcium/intracellular stressReducing pathological calcium overload, modulating intracellular calcium store signaling, limiting calcium-dependent stress cascades and endoplasmic reticulum stress couplingCellular stress burden, excitability-linked injury signaling, maladaptive plasticity, calcium-driven propagation of instabilityAttractive because calcium links neurons, glia, inflammatory signaling, and remodeling across multiple timescalesCalcium signaling is essential to normal physiology, so therapeutic selectivity is difficult; dominant calcium sources and effectors may vary across contextsEarly translational and mostly preclinical, with strong mechanistic relevance but limited clinically mature strategies [129, 151]
Limiting inflammatory amplificationTargeting cytokine pathways, innate immune signaling, blood–brain barrier-related dysfunction, or persistent inflammatory feedback loopsSeizure threshold, recovery environment, glia-mediated amplification, progression from acute disturbance to chronic instabilityMay be especially valuable in contexts where inflammation helps drive epileptogenic transition or chronic vulnerabilityInflammatory mechanisms are heterogeneous across syndromes and stages; broad immunosuppression may be ineffective or poorly targetedTranslationally active and biologically important, but likely to require more selective mechanism-guided use than generalized anti-inflammatory treatment [241, 243]
Network-level/precision approachesNeuromodulation, biomarker-guided stratification, surgery where appropriate, patient-specific models, systems-guided therapy selectionLarge-scale network synchrony, seizure propagation, patient-specific instability architecture, treatment matchingMost aligned with the review’s systems framework because it recognizes epilepsy as heterogeneous and mechanistically layeredRequires reliable biomarkers, better subtype stratification, and integration of mechanistic knowledge with patient-specific decision-makingAlready partly established in selected forms, but still evolving toward more precise and mechanism-guided implementation [229, 244, 246]
