Extending previous findings, and applying a novel multi-method translational approach, this project hypothesizes that there are alcohol-related neuroendocrine and neural changes observable in acute and protracted abstinence, and which can accurately classify future relapse and treatment outcome in separate alcohol dependent (AD) patient samples, thereby validating them as biomarkers of relapse, with potential clinical utility as prognostic markers in identifying and treating those most susceptible to relapse.

The MRI scan will be conducted on a 3-T Siemens Trio MRI system equipped with a standard quadrature head coil, using T1 MPRAGE sequence for structural scanning and T2\*-sensitive gradient-recalled single shot echo planar pulse sequence for functional scans. Two multimethod MRI scans will be conducted in the AD sample, while the controls will participate in a single scan.

Time to Relapse
The Time-Line Follow-Back Interview will be used to assess alcohol use in the previous ninety days, during the study and during follow-up until relapse occurs or 200 days is up.
Time frame: Up to 200 days
Time to heavy drinking relapse
The Time-Line Follow-Back Interview will be used to assess alcohol use in the previous ninety days (this is standard for TLFB surveys), during the study and during follow-up until relapse occurs or 200 days is up.
Time frame: Up to 200 days
Percent of days of alcohol use in follow-up
The Time-Line Follow-Back Interview will be used to assess alcohol use in the previous ninety days (which is standard for TLFB surveys), during the study and during follow-up. This can only be measured once relapse occurs. It will be measured once relapse occurs or will not be measured at all if relapse does not occur within 200 days.
Time frame: Up to 200 days
