Differences in pituitary-adrenal reactivity in Black and White men with and without alcohol use disorder.

Background: Treatment-seeking men with alcohol use disorder (AUD) classically exhibit a blunted hypothalamic-pituitary-adrenal (HPA) axis response to pharmacologic and behavioral provocations during the early phases of abstinence from alcohol. Independent of alcohol, a significant muting of HPA axis reactivity is also observed among racial minority (e.g.

Effects of acute alcohol and driving complexity in older and younger adults.

Rationale: Our previous work demonstrated differential neurobehavioral effects of low-dose alcohol consumption on older and younger adults in a driving simulator. However, the ability to enhance or suppress a response in such context has yet to be examined.

Objectives: The current study contrasted older and younger drivers' responses to specific stimuli (i.
