Neuroimaging technique help predict who is likely to have an easier time getting off drugs and alcohol and who will need extra help, says study.
"We can also see how brain activity changes as people recover from their addictions," said Joshua Brown, assistant professor in the Department of Psychological and Brain Sciences at Indiana University Bloomington, part of the College of Arts and Sciences.
The chronic occurrence of relapse underscores the need for improved methods of treatment and relapse prevention. One potential cause for relapse is deficient self-regulatory control over behavior and decision-making. Specifically this lack of self-regulatory ability in substance dependent individuals has been associated with dysfunction of a mesolimbic-frontal brain network. Reduced activity within this self-regulatory brain network has previously been implicated in relapse, but the specific relationship between this network, self-regulatory ability and recovery is yet to be determined.
The study, "Neural predictors and indicators of successful early recovery in substance dependent individuals," will be discussed from 11 a.m. to noon on Sunday in Hall F-J. Co-authors are S.E. Forster; and Peter R. Finn, also of the Department of Psychological and Brain Sciences.
