[Neurobiology and genetics of addiction].
Recent results on the neurobiological bases of addictive disorders allow new insights into the etiopathogenesis of addiction to be made and allow targets for new therapeutic strategies to be defined. An important advancement in the understanding of the underlying pathophysiology derives from recent research results, showing similarities between addiction and physiological neural plasticity in learning and memory. These include basic mechanisms involving dopamine, glutamate, and their cellular and molecular targets leading to drug-induced synaptic alterations in the mesolimbic reward system. Genetic factors modulate the individual vulnerability. The challenge of future research will be to generate more efficient and individualized therapies based on the insights from neurobiology and genetics.
