Involuntary retrieval of drug related thoughts is a hallmark of addicted populations.
Intensity of obsessive thoughts about alcohol predict relapse rate (1), with addicts motivated to use drugs to “silence” obsessive thoughts (2). The idea that abstinence automatically decreases alcohol-related thoughts is challenged by research (3) and supported by clinical observation that among abstinent alcohol abusers, alcohol-related thoughts and intrusions are the rule rather than exception (4).
Modell and colleagues (1992) highlighted symptomatic similarities between addiction and obsessive compulsive disorder with subjective craving for drugs or alcohol characterized as having obsessive elements. (eg, the compulsive drive to consume alcohol, recurrent and persistent thoughts about alcohol, and the struggle to control these drives and thoughts) similar to the thought patterns and behaviours of patients with obsessive-compulsive illness (5).
Modell et al. also point to the potential similarities in underlying neural pathways implicated in the two disorders, suggesting that they may share a similar aetiology. The Obsessive Compulsive Drinking Scale (OCDS) implies that as the severity of this illness progresses, so does the intensity of the obsessive thoughts about alcohol and the compulsive behaviours to use alcohol.
Kranzler et al. (1999) showed relapsers who scored higher in ‘obsessions’ craving measured by the OCDS predicted relapse in the 12 months after treatment completion (6).
This may also be a reflection of addiction severity too! As addicts and alcoholics become more addictive brain imaging shows a shift in “reward processing” from the ventral striatum to the dorsal striatum. The DS is in charge of more automatic, compulsive reaction. This shift from VS to DS may also be marked by an increased emergence of automatic thoughts, which the authors suggested as the cognitive thoughts and images of automatized drug action schemata (2).
In fact, this is demonstrated by correlations indicating that dorsal striatum activation is lowest in participants with low OCDS scores. This means, in simple terms, that more severe addiction may be associated with more intrusive/obsessive thoughts and less severe with less thoughts.
