| Description | Alcohol dependence is a multifactorial chronic relapsing disorder with no clear dominant etiological factors; rather, there is a large number of both genetic and psychosocial issues that increase the risk of dependence. Molecular genetics of alcohol dependence is, therefore, a very complex and the body of evidence is still dynamically evolving. It is linked with changes of glutamatergic, GABA-ergic, dopamine, serotonine, cholinergic, adrenergic, opioid, cannabinoid genes, genes that regulate stress response, and alcohol metabolism. These changes are manifested as abnormalities of reward system, motivational, hedonic and emotional processes, and inhibition and excitation mechanisms. Specific genetic susceptibility exists for withdrawal syndrome and its complications. |
