Halting retrieval of drug-associated memories may prevent addiction relapse

Disrupting the brain's retrieval of drug-associated memories may prevent relapse in drug addiction, according to new research in the August 13 issue of The Journal of Neuroscience. Researchers reduced drug-seeking behaviors in rats by blocking specific receptors in the brain during the recall of drug-associated memories. The NMDA-type glutamate receptor blocked in the study is important in learning and memory. The findings suggest potential new strategies to treat drug addiction in people.
