Alcohol Cravings Linked To Glutamate Levels

A new study, published by the Research Society on Alcoholism, has discovered that there may be an association between alcohol cravings and glutamate levels in some areas of the brain.

Researchers recruited 14 participants as part of an investigation into the physiological characteristics of alcohol cravings. Researchers used the Penn Alcohol Craving Scale (PACS) and a 30-day time line follow-back (TLFB 30), in order to measure alcohol cravings and drinking frequency. They also tests cerebral spinal fluid (CSF) for glutamate levels.

Results showed a correlation between CSF- glutamate levels and the PACS scores. These findings suggest that high glutamate levels were found in moments where the craving for alcohol was high, when compared to moment of lesser cravings.

These new findings may help to better tailor treatments, and assist with the management of alcohol cravings in individuals with alcohol use disorders.
