Background: Ethanol disrupts brain activity and memory. There is evidence supporting the beneficial effect of levetiracetam on alcohol consumption. Therefore, the aim of the study was to examine whether levetiracetam has a protective activity against ethanol-induced memory impairment, alterations in selected neurotransmission activities, oxidative stress, and selected essential elements in rats.

Background: Synthetic cathinones (SC) constitute the second most frequently abused class of new psychoactive substances. They serve as an alternative to classic psychostimulatory drugs of abuse, such as methamphetamine, cocaine, or 3,4-methylenedioxymethamphetamine (MDMA). Despite the worldwide prevalence of SC, little is known about their long-term impact on the central nervous system.

Background: Memory deficits and anxiety symptoms are undesirable effects that occur in epilepsy patients. They may be associated with the pathophysiology of the disease but also with anticonvulsant therapy. Brivaracetam (BRV) is one of the newest antiseizure drugs.

Antiepileptic drugs might be useful in the treatment of alcohol use disorder. One of these drugs is zonisamide, which has been found to decrease alcohol intake and cravings. An important structure in the pathophysiology of addiction is the hippocampus.

Objective: One of the newest antiseizure medication is levetiracetam (LEV). It might be effective in various indications, not only related to convulsions. Central nervous system disorders are common during anticonvulsant therapy.

Objective: Lacosamide (LC) belongs to a new generation of antiepileptic drugs (AEDs) and demonstrates unique mechanism of action. The drug also shows neuroprotective activity on the hippocampus. In this study, the impact of LC on learning processes was assessed.

Background: Retigabine belongs to the novel generation of antiepileptic drugs but its complex mechanism of action causes that the drug might be effective in other diseases, for instance, alcohol dependence. It is known that ethanol abuse impaired the function of brain structures associated with memory and learning such as the hippocampus. In our previous study, retigabine reduced hippocampal changes induced by ethanol in the EEG rhythms in rabbits.

Objective: Zonisamide is an antiepileptic drug with a perspective of a broader use. Although it is regarded as a relatively safe drug, zonisamide might cause disorders of the central nervous system. The study assessed the influence of zonisamide on spatial and emotional memory in adult Wistar rats.

Aims: Topiramate causes the inhibition of alcohol consumption in addicts but the mechanism of this action has not been fully understood yet. Nowadays, it seems that memory may have a role in the development of dependence. In this study, the impact of topiramate and ethanol on the bioelectric activity of the brain in rabbits and on spatial memory in rats was evaluated.

Objective: Retigabine is a novel antiepileptic drug with a unique and complex mechanism of action which allows its use in many diseases associated with impaired neuronal activity. This study sought to examine the impact of retigabine on two types of memory in rats.

Methods: Adult male Wistar rats were used to assess the effect of retigabine, administered p.

Aims: Zonisamide is a new anti-epileptic drug whose mechanism of action is associated with neurotransmission systems also involved in the pathogenesis of addiction. Recently, the role of memory processes and the hippocampus (Hp) is underlined in dependence. In our previous study, we determined that zonisamide decreases changes in hippocampal bioelectric activity induced by a single dose of ethanol.

New antiepileptic drugs have been investigated for their potential role in the treatment of alcohol dependence. One of these drugs is retigabine and this study examines the effect of retigabine co-administered with ethanol on the development of alcohol dependence and the course of acute withdrawal syndrome. A pharmaco-EEG method was used to examine this impact in selected brain structures of rabbits (midbrain reticular formation, hippocampus and frontal cortex).

Estrogens are widely used in hormone replacement therapy, gynecology, urogynecology and rarely in dermatology. Non-therapeutic use of estrogens is very widespread. Estrogens are used as contraceptives, which cause a lot of serious side effects.

Background: Retigabine is a new antiepileptic drug with multiple mechanisms of action. It may well interact with ethanol, as both have an influence on GABA-ergic and glutamate neurotransmission.

Objectives: To assess the effect of retigabine, administered as single or repeated doses, on ethanol-induced changes in the bioelectric activity of selected brain structures in rabbits.

Aims: Recent research suggests a potential role for a new generation of anticonvulsant drugs, including zonisamide, in the treatment of alcohol dependence. Some elements of the central mechanism of action that zonisamide has in common with ethanol, give rise to the question of whether there is an interaction between these two agents and whether there is any risk associated with the enhanced depressive effect of these agents on the central nervous system.

Methods: This study uses a pharmaco-EEG method to examine the interaction of ethanol with zonisamide.
