Metaphit induces audiogenic seizures in mice. The most severe clonic/tonic seizures occur 18-24 h after metaphit administration. After 48 h the incidence of the seizure episodes begin to diminish. These audiogenic seizures can be prevented by the administration of either PCP or MK-801 24 h after metaphit and 30 min prior to audio stimulation. These seizures may be due to a modulation of the PCP recognition site by metaphit which results in an enhanced probability that the NMDA/PCP ion channels are open.

Musicogenic epilepsy (ME) is characterized by seizures triggered by music. The epileptogenic focus in this rare reflex epilepsy is often in the temporal lobe, although the precise localization is still unclear. A correlation between ME and the presence of GAD65 antibodies indicates a potential immunological pathogenic mechanism.

Epilepsies are complex neurological entities usually co-existing with neuropsychiatric comorbidities. We already demonstrated that microinjection of oxytocin (OT) into the central nucleus of amygdala (CeA) induces hypergrooming in Wistar rats, a model of compulsion. Furthermore, the Wistar Audiogenic Rat (WAR) strain is a genetic model of generalized tonic-clonic seizures.

The primary objective of this study was to examine neurological disorders and cognitive impairments in patients with secondary hypothyroidism and epilepsy undergoing treatment with antiepileptic medications. The study included 184 patients divided into three groups: Group 1 (subclinical hypothyroidism, n = 60), Group 2 (manifest hypothyroidism, n = 64), and Group 3 (control, n = 60). Patients in Group 2 received levothyroxine therapy (initial dose of 25 μg/day, titrated to 50-100 μg/day), while Groups 1 and 2 were treated with anti-seizure medications (valproic acid, 40 mg/kg/day).

Accumulating evidence indicates that inherited astrocyte dysfunction can be a primary trigger for epilepsy development; however, the available data are rather limited. In addition, astrocytes are considered as a perspective target for the design of novel and improvement of the existing antiepileptic therapy. Piracetam and related nootropic drugs are widely used in the therapy of various epileptic disorders, but detailed mechanisms of racetams action and, in particular, their effects on glial functions are poorly understood.
