MRS Probe Study of Alcohol
Magnetic Resonance Spectroscopy Probe Study of Alcohol Use
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

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:

  1. Inability to speak English
  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.
