Nucleus Accumbens Stimulation Modulates Inhibitory Control by Right Prefrontal Cortex Activation in Obsessive-Compulsive Disorder. Cereb Cortex 2021; 31:2742-2758. [PMID: 33406245 DOI: 10.1093/cercor/bhaa397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Revised: 12/03/2020] [Accepted: 12/11/2020] [Indexed: 11/14/2022] Open
Abstract
Inhibitory control is considered a compromised cognitive function in obsessive-compulsive (OCD) patients and likely linked to corticostriatal circuitry disturbances. Here, 9 refractory OCD patients treated with deep brain stimulation (DBS) were evaluated to address the dynamic modulations of large-scale cortical network activity involved in inhibitory control after nucleus accumbens (NAc) stimulation and their relationship with cortical thickness. A comparison of DBS "On/Off" states showed that patients committed fewer errors and exhibited increased intraindividual reaction time variability, resulting in improved goal maintenance abilities and proactive inhibitory control. Visual P3 event-related potentials showed increased amplitudes during Go/NoGo performance. Go and NoGo responses increased cortical activation mainly over the right inferior frontal gyrus and medial frontal gyrus, respectively. Moreover, increased cortical activation in these areas was equally associated with a higher cortical thickness within the prefrontal cortex. These results highlight the critical role of NAc DBS for preferentially modulating the neuronal activity underlying sustained speed responses and inhibitory control in OCD patients and show that it is triggered by reorganizing brain functions to the right prefrontal regions, which may depend on the underlying cortical thinning. Our findings provide updated structural and functional evidence that supports critical dopaminergic-mediated frontal-striatal network interactions in OCD.

Neurosci Biobehav Rev 2019; 108:617-645.

Abstract
To-date it has been difficult to ascertain the exact cognitive profile of childhood OCD as studies report variable results. Adult OCD research lately utilises the endophenotype approach; studying cognitive traits that are present in both patients and their unaffected first-degree relatives, and are thought to lie closer to the genotype than the full-blown disorder. By observing whether candidate endopenotypes of adult OCD are present in child patients, we can determine whether the two subtypes show cognitive overlap. We conducted a systematic review of the paediatric OCD literature focussing on proposed neurocognitive endophenotypes of OCD: cognitive flexibility, response inhibition, memory, planning, decision-making, action monitoring, and reversal learning. We found that paediatric patients present robust increases in brain error related negativity associated with abnormal action monitoring, impaired decision-making under uncertainty, planning, and visual working memory, but there is less evidence for deficits in other cognitive domains. This implies that children with OCD show some cognitive similarities with adult patients, but other dysfunctions may only manifest later in the disorder trajectory.

Early cognitive processes in OCD: An ERP study. J Affect Disord 2019; 246:429-436.

Abstract
BACKGROUND Obsessive-compulsive disorder (OCD) is characterized by persistent, intrusive, and distressing obsessions and/or compulsions and is associated with marked impairments in quality of life. The goal of the present study was to examine initial stages of information processing, specifically, perceptual and attention orientation phases that precede response preparation in OCD. METHODS The P3 event-related potential (ERP) component was used as a measure of early cognitive processes of visual stimulus perception. ERPs were recorded while 38 participants diagnosed with OCD and 38 healthy controls performed a passive visual oddball task with neutral and angry schematic faces. RESULTS OCD participants demonstrated significantly enhanced P3 amplitude over bilateral parietal areas in response to neutral stimuli that activate basic primary perceptual processes. Emotional valence reduced this effect such that OCD patients did not differ from healthy controls in P3 amplitude under the angry stimuli condition. LIMITATIONS Patients in this study were noncomorbid and unmedicated partially limiting the generalizability of the results. CONCLUSIONS Our hypothesis of altered early perceptual processes in OCD was supported. These alterations, specific to OCD and not anxiety and depression symptoms, may represent distracted primary cognitive processes in OCD, possibly serving as a basic source for compulsion initiation.

Methadone maintenance patients show a selective deficit to reverse positive outcomes in drug-related conditions compared to medication free prolonged opiate abstinence. Drug Alcohol Depend 2014; 144:111-8. [PMID: 25220895 DOI: 10.1016/j.drugalcdep.2014.08.016] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2014] [Revised: 08/23/2014] [Accepted: 08/24/2014] [Indexed: 11/20/2022]
Abstract
BACKGROUND Drug addiction is a chronic relapsing disease. Most users will relapse back to using drugs over and over again throughout their life. These relapses may become more frequent in the presence of contextual reminders. We aimed to examine associations between the ability to maintain a medication-free life-style and the capability to learn and reverse positive and negative stimulus-outcome associations in the presence of neutral and drug-related contextual reminders. METHODS We conducted a highly unique comparison of former opiate-dependent individuals who are either medication free or methadone maintenance patients for the last ten years. Groups were matched for age, gender and education. Participants were tested on a novel partial reversal paradigm, which tests the ability to acquire and reverse stimulus-outcome associations in neutral and drug-related context. RESULTS Both groups were equally able to acquire and reverse positive and negative outcomes in conditions of neutral context. However, methadone maintenance patients showed a selective deficit in reversing the outcomes of positive stimulus in drug-related context. Hence, after learning a positive stimulus-outcome association in one drug-related context, methadone maintenance patients struggled to learn that the same stimulus predicts negative outcome when presented later in a different drug-related context. CONCLUSIONS Methadone maintenance patients demonstrate a selective difficulty to learn negative outcomes when exposed to a drug, but not neutral, related environment. The results may reflect the core mechanisms of addiction and provide a possible explanation for the inability of methadone maintenance patients to illicit drug abuse without the need of agonist treatment.
