Background: Scientific evidence to guide clinicians on the use of different antiseizure drugs in combination therapy is either very limited or lacking. In this study, the impact of lacosamide and perampanel alone and in combination was tested in corneal kindling model in mice, which is a cost-effective mechanism for screening of antiseizure drugs.
Methods: The impact of lacosamide (5 mg/kg) and perampanel (0.

Methionine sulfoximine (MSO) is a compound originally discovered as a byproduct of agene-based milled flour maturation. MSO irreversibly inhibits the astrocytic enzyme glutamine synthase (GS) but also interferes with the transport of glutamine (Gln) and of glutamate (Glu), and γ-aminobutyric acid (GABA) synthesized within the Glu/Gln-GABA cycle, in this way dysregulating neurotransmission balance in favor of excitation. No wonder that intraperitoneal administration of MSO has long been known to induce behavioral and/or electrographic seizures.

Inbreeding depression (ID) is a well-documented phenomenon associated with reduced fitness and possible extinction. However, ID can be mitigated or even eliminated through the interplay of inbreeding and selection, a process known as purging. The aim of this study was to compare the predictive power of two commonly used approaches in models with and without random dam effects to detect purging (full and reduced models).

Seizures can lead to cardiac dysfunction. Multiple pathways contribute to this phenomenon, of which the chaperone sigma-1 receptor (S1R) signaling represents a promising nexus between the abnormalities seen in both epilepsy and ensuing cardiac complications. The study explored the potential of Berberine (BER), a promising S1R agonist, in treating epilepsy and associated cardiac abnormalities in a pentylenetetrazol (PTZ) kindling rat model of epilepsy.

Seizures in people with Alzheimer's disease are increasingly recognized to worsen disease burden and accelerate functional decline. Harnessing established antiseizure medicine discovery strategies in rodents with Alzheimer's disease associated risk genes represents a novel way to uncover disease modifying treatments that may benefit these Alzheimer's disease patients. This commentary discusses the recent evaluation by Dejakaisaya and colleagues to assess the antiseizure and disease-modifying potential of the repurposed cephalosporin antibiotic, ceftriaxone, in the Tg2576 mouse model.
