Ethanol, GABA end epilepsy

Ethanol exerts its behavioral effects largely by interacting with receptors to brain neurotransmitters. The molecular mechanisms involving these interactions are still not well known since an ideal model for their study is currently unavailable. In addition, responses to alcohol may vary due to factors such as genetic predisposition, ethanol concentration consumed, and stimuli such as stress, socialization, etc. The chronc consumption of alcohol, similar to that of other drugs such as benzodiazepines and barbiturates, is linked to GABAerigc neurotransmission. GABA is the predominant inhibitory neurotransmitter in the brain. In context of substance abuse, these three drugs first cause a gratifying effect, later tolerance and finally, physical and psychological dependence. If cosumption is interrupted abruptly, a withdrawal syndrome occurs. The Alcohol Withdrawal Syndrome (AWS) is state of hyperexcitability characterized by anxiety, fear, muscular rigidity and tonic-clonic seizures with epileptiform-type charactermental epilepsy models such as "Kindling" or GABA Withdrawal Syndrome (GWS) models. A possible correlation between these models and AWS will allow for a better understanding of the cellular and molecular effects that alcohol exerts on the brain
