Brief Summary:
This protocol will investigate the neurobiological underpinnings of alcohol craving in recently detoxified alcoholic drinkers utilizing novel functional brain imaging. This clinical magnetic resonance spectroscopy (MRS) study will investigate whether glutamate and other brain metabolites correlate to measures of alcohol craving severity

Condition or disease Intervention/treatment Phase
Heavy Dose Drinkers Procedure: Magnetic Resonance Spectroscopy Not Applicable

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 40 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Official Title: Magnetic Resonance Spectroscopy Probe Study of Alcohol Use
Study Start Date : August 2012
Actual Primary Completion Date : March 2014
Actual Study Completion Date : June 2014

Intervention Details:
  • Procedure: Magnetic Resonance Spectroscopy
    Other Name: MRS


Primary Outcome Measures :
  1. Utilizing Magnetic Resonance Spectroscopy at 3 Tesla, investigate the neurobiological underpinnings of alcohol craving
    assessing baseline perturbations in anterior cingulate and ventral striatal metabolites (NAA levels, glutamate levels, glutamine levels)


Secondary Outcome Measures :
  1. Evaluate the relationship between these metabolites, each reported as a Cerebrospinal Fluid-corrected absolute concentration, and severity of alcohol cravings
    Evaluate the relationship between these metabolites, each reported as a Cerebrospinal fluid-corrected absolute concentration, and severity of alcohol cravings, as measured primarily by the Penn Alcohol Craving Scale and secondarily by the Inventory of Drug Taking Situations.

Criteria

Inclusion Criteria: (Minimal or No Alcohol Group)

  1. Male or female age 21-70
  2. Consume less alcohol then what is described in this protocol as a "higher dose drinker", or consume no alcohol at all.
  3. Able to complete a 60 min. MRS brain scan.

Exclusion Criteria:

  2. Inability or unwillingness to provide written informed consent
  3. Diagnosis of active substance dependence other than nicotine (e.g. alcohol, cannabis, caffeine, prescription use of barbiturates, benzodiazepines, opiates, or stimulants) this will be determined using a PRISM (Psychiatric Research Interview for Substance and Mental Disorders) interview.
