Stress Neuroadaptations in Addiction

Preclinical animal models have convincingly demonstrated that stress neuroadaptations in response to chronic alcohol and other drug (AOD) use play an important role in addiction etiology and relapse following treatment. My laboratory has been instrumental in translating these findings from animals to human AOD users. We have also demonstrated that these stress neuroadaptations manifest as exaggerated reactivity selectively to unpredictable or otherwise uncertain stressors. These studies implicate the corticotropin-releasing factor (CRF) and noradrenergic (NE) neurotransmitter systems as potential partial mediators of these stress neuroadaptations and we have initiated research to confirm this via pharmacological manipulation of these neurotransmitter systems. Pharmacological or behavioral manipulation of the CRF and NE stress systems also emerges as innovative interventions suggested by this body of research.
