Ketogenic diet fails to mitigate seizures and neuroinflammatory responses in a mouse model of virus‐induced epilepsy

Epilepsia, EarlyView.
Abstract Objective The ketogenic diet (KD) is a high‐fat, low‐carbohydrate intervention widely used to treat drug‐resistant epilepsy, thought to reduce seizures through a combination of metabolic, neuronal, and microbiota‐dependent mechanisms. Additionally, recent studies suggest that the anticonvulsant effects of KD require the gut microbiota, with ...

Theta oscillations, epileptogenesis, and focal seizures in rodent models of mesial temporal lobe epilepsy

Epilepsia, EarlyView.
Abstract Theta oscillations (4–12 Hz) are a prominent network rhythm within hippocampal and parahippocampal structures. Driven by cholinergic and γ‐aminobutyric acidergic inputs originating from the medial septum, physiological theta gates network excitability to control spatial navigation, memory encoding, and sensorimotor integration during specific ...

Kv3.1 activation suppresses provoked and spontaneous seizures in a mouse Dravet syndrome model

Epilepsia, EarlyView.
Abstract Objective γ‐Aminobutyric acidergic (GABAergic) parvalbumin‐positive (PV+) interneurons are critical for maintaining cortical inhibitory tone, with their dysfunction predictably leading to epilepsy. Rapid PV+ interneuron firing is essential for their normal function and is maintained in part by potassium voltage‐gated channels.

Adeno‐associated virus‐mediated restoration of NaV1.1 in targeted brain regions ameliorates epilepsy in symptomatic Dravet syndrome mice

Epilepsia, EarlyView.
Abstract Objective Dravet syndrome (DS) is a developmental and epileptic encephalopathy primarily caused by haploinsufficiency of the SCN1A gene, which encodes the alpha subunit of NaV1.1 voltage‐gated sodium channel. The disease manifests with febrile and spontaneous seizures, developmental delay, cognitive impairment, and increased risk of sudden ...

Transcriptomic analysis reveals distinct expression patterns in focal cortical dysplasia

Epilepsia, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) is a common cause of drug‐resistant epilepsy in children and adults and exhibits substantial clinical and histopathological heterogeneity. However, morphological classification alone does not fully explain variability in epileptogenicity, disease severity, or treatment response.

Timing is everything: The effect of early‐life seizures on developing neuronal circuits subserving spatial memory

Epilepsia Open, EarlyView.
Abstract Spatial memory, the aspect of memory involving encoding and retrieval of information regarding one's environment and spatial orientation, is a complex biological function incorporating multiple neuronal networks. Hippocampus‐dependent spatial memory is not innate and emerges during development in both humans and rodents.

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

Epilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.

New insights into epileptic spasm generation and treatment from the TTX animal model

Epilepsia Open, EarlyView.
Abstract Currently, we have an incomplete understanding of the mechanisms underlying infantile epileptic spasms syndrome (IESS). However, over the past decade, significant efforts have been made to develop IESS animal models to provide much‐needed mechanistic information for therapy development.

Precision therapies for genetic epilepsies in 2025: Promises and pitfalls

Epilepsia Open, EarlyView.
Abstract By targeting the underlying etiology, precision therapies offer an exciting paradigm shift to improve the stagnant outcomes of drug‐resistant epilepsies, including developmental and epileptic encephalopathies. Unlike conventional antiseizure medications (ASMs) which only treat the symptoms (seizures) but have no effect on the underlying ...

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...
