Addiction may not always be a fixed personality or genetic trait, instead the result of our plastic brains learning the effect of drugs on our individual responses and the environmental setting in which the substance is used.
A new large-scale genome-wide study has identified 18 new genetic risk factors for opioid use disorder, bringing the number of OUD-associated genes from 1-19.
Study finds a link between the personality trait of perfectionism and severe alcohol use disorder.
The activity of MCH neurons in the lateral hypothalamus during sleep recapitulates REM sleep effects on reducing drug-seeking behaviors.
