Reversible brain hyperthermia during audiogenic seizures in rats. Acta Physiol. Pol., 1979, 30 (2): 273--277. Nine rats having inborn audiogenic susceptibility had chronically implanted Cu-constantan thermocouple and epidural EEG electrodes sewed into the skull. In freely moving animals audiogenic seizures were provoked by the use of common electric bell (approx. 100 dB). The EEG trace and brain temperature (with the accuracy of 0.05 degrees C) were recorded simultaneously during 1--8 hours. Temperature increases found during 23 audiogenic seizures were similar to those noted during intensive locomotor activity of animals without seizures. In thermoneutral environment (23 +/- 2 degrees C and humidity 65% +/- 10%) brain temperature never exceeded 41 degrees C.

Mechanisms of vagus nerve stimulation for the treatment of neurodevelopmental disorders: a focus on microglia and neuroinflammation.

The vagus nerve (VN) is the primary parasympathetic nerve, providing two-way communication between the body and brain through a network of afferent and efferent fibers. Evidence suggests that altered VN signaling is linked to changes in the neuroimmune system, including microglia. Dysfunction of microglia, the resident innate immune cells of the brain, is associated with various neurodevelopmental disorders, including schizophrenia, attention deficit hyperactive disorder (ADHD), autism spectrum disorder (ASD), and epilepsy.

Epilepsy Unit, Fondazione IRCCS Istituto Neurologico Carlo Besta, Milan, Italy.
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).
