{"title":"Defending and defining compulsive behaviour in addiction","authors":"Karen D. Ersche","doi":"10.1111/adb.13427","DOIUrl":"10.1111/adb.13427","url":null,"abstract":"&lt;p&gt;Heinz and colleagues provide interesting insights into the clinical presentation of drug-taking habits and the associated difficulties of breaking them. Although they do not question the existence of habits in addiction, they raise concerns about the psychological construct of habit and its role in the development of compulsivity in addiction.&lt;/p&gt;&lt;p&gt;The authors doubt that compulsive behaviour in addiction arises from a predominance of habits over goal-directed behaviour, as suggested by the habit theory.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; Their arguments are based on descriptions of differences in clinical phenotypes of compulsivity in addicted patients and patients with obsessive-compulsive disorder (OCD), without mentioning the many commonalities. For example, they explain that avoidance behaviour in OCD patients is negatively reinforced through the relief of anxiety but do not say that hoarding behaviour in OCD patients is positively reinforced.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; Likewise, they emphasise that the use of alcohol is positively reinforced by its pleasurable effects but do not mention the fact that negative reinforcement underlies chronic opioid use.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; Similar commonalities are also evident in the brain, as reflected by an overlapping neuropathology underlying self-reported compulsivity in both OCD and addiction.&lt;span&gt;&lt;sup&gt;4&lt;/sup&gt;&lt;/span&gt; Focussing solely on different manifestations of orbitofrontal dysfunction (i.e., cases of overactivity or underactivity) distracts from the fact that the same system is impaired in both disorders but expressed in different ways. I wonder whether the authors' questioning of the role of compulsivity in addiction derives from an understanding that equates the psychological concept of compulsivity (i.e., the maladaptive continuation/perseveration of behaviour) with clinical symptoms of compulsions. Compulsive symptoms can of course be expressed in many different ways, as exemplified by the authors' clinical case of an OCD patient with comorbid compulsive alcohol use and gambling behaviour. Whilst there are variations of compulsive symptoms across different disorders, the psychological concept underpinning these behavioural manifestations is the same, namely, a reflection of ongoing actions that have become inappropriate to the immediate context.&lt;/p&gt;&lt;p&gt;Moreover, it is worth clarifying that the habit theory does not contradict their observations. Habits (including habitual drug use) do not necessarily develop into compulsions because most people are able to break their habits. If habits are, however, learned under the influence of drugs or stress, the formation of habits is facilitated. In people with impaired prefrontal inhibitory control (such as patients with OCD or addiction), habits run the risk of persisting even if they no longer produce the desirable effects or lead to adverse consequences. This only affects a minority of drug users, as just 15%–20% are thought to develop addiction.&lt;span&gt;&lt;","PeriodicalId":7289,"journal":{"name":"Addiction Biology","volume":"29 8","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/adb.13427","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141917866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We tested the hypothesis that chronic pain would increase oxycodone-seeking behaviour and that the pain state would differentially increase intrinsic excitability in dmPFC drug-seeking ensemble neurons. TetTag mice self-administered intravenous oxycodone. After 7 days of forced abstinence, a drug-seeking session was performed, and the ensemble was tagged. Mice received spared nerve injury (SNI) to induce chronic pain during the period between the first and second seeking session. Following the second seeking session, we performed electrophysiology on individual neurons within the dmPFC to assess intrinsic excitability of the drug-seeking ensemble and non-ensemble neurons. SNI had no impact on sucrose seeking or intrinsic excitability of dmPFC neurons from these mice. In females, SNI increased oxycodone seeking and intrinsic excitability of non-ensemble neurons.

Previous preclinical studies suggested that direct blockade of CB1 cannabinoid receptors (CB1R) could be leveraged as a potential pharmacological approach to treat substance use disorder, but this strategy failed during clinical trials due to severe psychiatric side effects. Alternative strategies have emerged to circumvent the side effects of direct CB1 binding through the development of allosteric modulators. We hypothesized that negative allosteric modulation of CB1R signalling would reduce the reinforcing properties of morphine and decrease behaviours associated with opioid misuse. By employing intravenous self-administration in mice, we studied the effects of GAT358, a functionally-biased CB1R negative allosteric modulator (NAM), on morphine intake, relapse-like behaviour and motivation to work for morphine infusions. GAT358 reduced morphine infusion intake during the maintenance phase of morphine self-administration under a fixed ratio 1 schedule of reinforcement. GAT358 also decreased morphine-seeking behaviour after forced abstinence. Moreover, GAT358 dose dependently decreased the motivation to obtain morphine infusions under a progressive ratio schedule of reinforcement. Strikingly, GAT358 did not affect the motivation to work for food rewards in an identical progressive ratio task, suggesting that the effect of GAT358 in decreasing opioid self-administration was reward specific. Furthermore, GAT58 did not produce motor ataxia in the rotarod test. Our results suggest that CB1R NAMs reduced the reinforcing properties of morphine and could represent a viable therapeutic route to safely decrease misuse of opioids.</p>","PeriodicalId":7289,"journal":{"name":"Addiction Biology","volume":"29 8","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11304470/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141898723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We first validated the ability of retigabine to target experimenter-delivered cocaine in a conditioned place preference (CPP) assay and found that retigabine reduced the acquisition of place preference. Next, we trained rats for cocaine-SA under a fixed-ratio or progressive-ratio reinforcement schedule and found that retigabine pretreatment attenuated the SA of low to moderate doses of cocaine. This was not observed in parallel experiments, with rats self-administering sucrose, a natural reward. Compared with sucrose-SA, cocaine-SA was associated with reductions in the expression of the K<sub>v</sub>7.5 subunit in the nucleus accumbens, without alterations in K<sub>v</sub>7.2 and K<sub>v</sub>7.3.
