Background:
Patients with obsessive-compulsive disorder (OCD) experience an exacerbation of symptoms under psychological distress. The neurobiological underpinnings of this effect of stress remain elusive. Here, we induced psychological distress to explore its effect on neural reactivity of the salience network during a symptom provocation task....
The specific mechanisms underlying compulsive behavior in obsessive-compulsive disorder (OCD) are unknown. It has been suggested that such compulsivity may have its origin in cognitive dysfunction such as impaired processing of feedback information, received after the completion of goal-directed actions. The signal attenuation (SA) task models such...
The classical cognitive-behavioral theory of obsessive-compulsive disorder (OCD) holds that compulsions are performed to reduce distress that is evoked by obsessions, whereas a recent neuroscience-inspired theory suggests that compulsivity results from a disbalance between goal-directed and habit-related neural networks. To bridge these theories, w...
Introduction:
It has been proposed to extend the cognitive-behavioural model of obsessive-compulsive disorder (OCD) with attachment theory to shed light on the affective and developmental factors underlying the disease. With a growing number of empirical studies on the subject, this meta-analysis aims to quantify a possible relationship between at...
Introduction: The classical cognitive-behavioral theory of obsessive-compulsive disorder (OCD) holds that compulsions (repetitive behaviors) are performed to reduce distress that is evoked by obsessions (intrusive thoughts), whereas a recent neuroscience-inspired theory suggests that compulsivity results from a disbalance between goal-directed and...
A 24-year-old man took 20 grams of paracetamol during a hospital stay in the department of psychiatry. It was not until 60 hours later that therapy with acetylcysteine was initiated. Paracetamol intoxication has a long latency period. If there is no intervention, severe hepatic damage can develop within three days. Even after a few days have passed...
The basolateral amygdala (BLA) has a crucial role in emotional learning irrespective of valence. The BLA projection to the nucleus accumbens (NAc) is thought to modulate cue-triggered motivated behaviours, but our understanding of the interaction between these two brain regions has been limited by the inability to manipulate neural-circuit elements...
