The influence of GABA injection (intraperiotoneal) on the sensitivity to sound and behaviour was studied on KM line rats, in which a strong sound produces epileptiform seizures, and on sound-resistant Wistar line rats. It was shown that in the KM line rats the previously elaborated motor alimentary conditioned reflex was impaired for several hours after the seizures. The two first GABA injections to the rats of both lines reduce the number of adequate reactions to a signal stimulus. As GABA injections are repeated, conditioned activity is restored. A four-time GABA injection results in blocking of the audiogenic seizures in a number of rats of the KM line and in the maintenance of normal behaviour after the action of the epileptogenic stimulus.

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.

Startle epilepsy, characterized by startle-provoked epileptic seizures, was historically recognized as one of the reflex epilepsies but currently lacks classification as a specific epileptic syndrome because of insufficient characterization. This study presents an institutional experience and review of relevant literature focusing on the neurophysiologic and anatomical aspects of startle epilepsy. We describe a pediatric patient with an underlying structural etiology of left frontal encephalomalacia who continued to experience disabling seizures despite multiple antiseizure medications and previous palliative surgery.

Background: Syncope is a common medical condition. The reflex or neurally mediated syncope (NMS) is the most frequent type. The tilt table test (TTT) helps distinguish syncope from other common causes of complete loss of consciousness, such as epilepsy, define syncope subtypes and guide management.
