摘要: Activation of the hypothalamic-pituitary-adrenal (HPA) axis leads to elevations in γ-aminobutyric acid (GABA)-ergic neuroactive steroids that enhance GABA neurotransmission and restore homeostasis following stress. This regulation HPA maintains healthy brain function protects against neuropsychiatrie disease. Ethanol sensitivity is influenced by GABAergic effects ethanol, mayprevent excessive drinking rodents humans. Low ethanol associated with greater alcohol consumption increased risk ofalcoholism. Indeed, ethanol-dependent rats show blunted neurosteroid responses administration may contribute tolerance propensity drink amounts ethanol. The review presents evidence support hypothesis neurosteroids actions prevent drinking, while lack underlie innate or chronic drinking. Neurosteroids have therapeutic use withdrawal for relapse prevention.
