ABSTRACT

Se presenta el caso clínico de un paciente de 72 años sin antecedentes psiquiátricos previos que ingresa en el Servicio de Neurología por infarto cerebral en territorio vertebrobasilar. Durante el ingreso presenta elevada ansiedad secundaria a una ideación obsesiva de contenido erótico con intensa repercusión emocional y conductual. Se inicia tratamiento sintomático con Quetiapina, observándose mejoría progresiva del cuadro hasta la total recuperación del paciente. En el presente artículo se revisa la relación entre las diferentes áreas anatómicas cerebrales y la aparición de clínica obsesiva


A 72 year old male without previous psychiatric history is admitted to the neurology department due to vertebrobasilar stroke. During the stay, the patient manifests a high level of anxiety related to the onset of an erotic obsessive idea with an intense emotional and behavioural repercussion. Symptomatic treatment with quetiapine was started, with a progressive improvement of the symptoms until it's complete resolution. In the present article, we aim to review the relationship between the different brain anatomical areas and the onset of obsessive symptoms

ABSTRACT

OBJECTIVE: In a longitudinal field study, we investigated the predictive associations between six aberrant personality tendencies (schizotypal, avoidant, borderline, antisocial, narcissistic, obsessive-compulsive) and academic success of science, technology, engineering, and mathematics students. METHOD: Bachelor students of Industrial Engineering at a Dutch technical university (N = 432, Mage  = 18.45; 87.3% male) filled out the NEO-PI-R and aberrant tendencies were operationalized by the five-factor model (FFM) compound technique. Indicators of academic achievement (grades) and persistence (credit points earned per year, re-enrollment, study duration) were made available by the academic office. RESULTS: Validities across the 3 years of the study program consistently support the role of two aberrant tendencies: Individuals with high antisocial tendency reached lower academic achievement, took longer to finish their study, and had a higher risk of dropout. The obsessive-compulsive tendency was associated with higher grade-point average, faster study progress, and higher retention rates and effects were still visible while controlling for known predictors (high school grades, Conscientiousness). Contrary to our expectations, we found no evidence for inverted U-shaped relationships. CONCLUSIONS: We used the compound technique for aberrant tendencies based on the FFM in the academic context and our findings support the importance of personality-based psychopathological tendencies for academic success.

ABSTRACT

OBJECTIVE: The aim of this study was to analyze the potential association between personality traits and onabotulinumtoxin A (onabotA) response in patients with chronic migraine (CM). BACKGROUND: Previous studies from a categorial perspective show that patients with CM have anxious or obsessive personality according to the Salamanca screening test. However, the influence of personality traits in onabotA response in patients with CM has not yet been studied. We hypothesize that cluster C personality traits may be associated with non-response to onabotA. METHODS: This case-control observational study includes patients with CM who received at least 2 treatment cycles of onabotA in 2 headache units between January and May 2018. onabotA response was defined as a reduction of at least 50% in the number of monthly migraine days. Personality traits were evaluated using the Salamanca questionnaire, a validated categorial inventory assessing 11 personality traits. RESULTS: One hundred and twelve patients, 100/112 (89.6%) females, mean age (standard deviation): 43 (11) years, were recruited. 96/112 (85.7%) achieved response to onabotA. Dependent trait was significantly associated with non-response to onabotA (P = .008; OR: 0.223 [95%CI: 0.074 to 0.675]). Significant association with other personality traits or confounders was not found. CONCLUSIONS: To the best of our knowledge, this is the first study showing personality traits may predict onabotA response in patients with CM. The presence of dependent personality trait in patients with CM is associated with non-response to onabotA.

ABSTRACT

Background: Whereas the phenomenology of obsessive-compulsive personality disorder (OCPD) shows similarities to that of obsessive compulsive and related disorders (OCRDs) as well as with autism spectrum disorder (ASD), the relationship between these disorders is poorly understood.Aims: Within a clinical sample, we aimed to investigate the distribution of OCD, OCPD and ASD symptoms and traits and their interrelationship, as well as to evaluate insight and treatment refractoriness.Methods: Consecutive adult OCD outpatients were assessed for OCPD traits (Compulsive Personality Assessment Scale (CPAS)), OCD symptoms (Yale-Brown Obsessive Compulsive Scale (Y-BOCS)), ASD traits (Autism Spectrum Quotient (AQ)), insight (Brown Assessment of Beliefs Scale (BABS)) and treatment resistance (clinical records). Those scoring highly on the AQ underwent a diagnostic interview for ASD.Results: Sixty-seven consenting individuals completed the CPAS, BABS and AQ, and 65 completed the Y-BOCS. Twenty-four patients (35.8%) were diagnosed with OCPD. Patients with OCPD were less likely to be employed (p=.04). They demonstrated elevated AQ scores (p=.004) and rates of ASD diagnosis (54.2%) (p <.001). OCPD traits (CPAS) showed a highly significant correlation with ASD traits (AQ) (p<.001), and no association with Y-BOCS, BABS or treatment resistance.Conclusions: In an OCD cohort limited by small size, OCPD associated strongly with unemployment and ASD, with implications for diagnosis, treatment and outcome.KEY POINTSClinicians should exercise a high level of vigilance for OCPD and ASD in patients presenting with obsessive compulsive symptoms.The presence of OCPD may indicate a likelihood of disabling ASD traits, including cognitive inflexibility, poor central coherence and poor social communication.These neuropsychological factors may require separate clinical intervention strategies.

ABSTRACT

Research is scarce regarding personality disorder traits of individuals with subclinical obsessive-compulsive symptoms. Cluster analysis based on obsessional, schizotypal, and borderline personality and autism-spectrum features was conducted on the results for 118 students scoring above cutoff on the Obsessive Compulsive Inventory-Revised. This identified four groups: O, L, S, and A. One third of the sample was represented by individuals with obsessional traits (O), while another third was composed of individuals with low traits (L); the last two profiles corresponded to a cluster with autistic traits (A) and a group with schizotypal and borderline features (S), both clusters together comprising the remaining third. Significant differences were observed between groups, both on personality traits and on psychopathological symptoms. The S cluster displayed the highest scores of suicidality, depression, and obsessive-compulsive symptoms. This study identified meaningful profiles of personality disorder traits, distinct from obsessive-compulsive personality, in individuals with subclinical obsessive-compulsive symptoms.

ABSTRACT

People with epilepsy often suffer psychiatric symptoms or exhibit maladaptive personality characteristics which can impact them more than seizures. This case illustrates a selective association of a Theory of Mind dysfunction, including an impaired comparison of reality and others' behavior, with an obsessive-compulsive personality disorder in a patient with left temporal lobe epilepsy and crossed cognitive functions. The patient revealed visual memory deficits and impaired interpretation of other people's behavior, mental rigidity, and a tendency to formulate inflexible judgements. Moreover, she shows impairment in understanding and sharing the emotional states of others in reference to herself (Empathic Quotient); her social relations are limited to her parents. Patients with right temporal lobe epilepsy frequently report persistent and rigid actions and thoughts, and this can have substantial psychological and social consequences for everyday life. We suggest that this could be a case of crossed cognitive functions, in particular ToM, and crossed psychobehavioral functions linked to right-hemisphere damage.

ABSTRACT

The current study evaluated the continuity between the diagnostic operationalizations of obsessive-compulsive personality disorder (OCPD) in the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition, both as traditionally operationalized and from the perspective of the alternative model of personality disorders. Using both self-report and informant measures, the study had the following four aims: (a) to examine the extent to which self-report and informant data correspond, (b) to investigate whether both self-report and informant measures of the alternative model of OCPD can predict traditional OCPD, (c) to determine if any traits additional to those proposed in the alternative model of OCPD can predict traditional OCPD, and (d) to investigate whether a measure of OCPD-specific impairment is better at predicting traditional OCPD than are measures of general impairment in personality functioning. A mental health sample of 214 participants was recruited and administered measures of both the traditional and alternative models of OCPD. Self-report data moderately corresponded with informant data, which is consistent with the literature. Results further confirmed rigid perfectionism as the core trait of OCPD. Perseveration and workaholism were also associated with OCPD. Hostility was identified as a trait deserving further research. A measure of OCPD-specific impairment demonstrated its ability to incrementally predict OCPD over general measures of impairment. (PsycINFO Database Record

ABSTRACT

DSM-5's Section III Alternative Model for Personality Disorder (AMPD) model states that an individual must show impairment in self and interpersonal functioning for PD diagnosis. The current study investigated dimensional personality trait associations with impairment, including differential patterns of impairment across specific PDs, and whether traits have improved our assessment of functional impairment in PDs. Two-hundred and seventy-seven participants were administered measures of Antisocial PD, Avoidant PD, Borderline PD, Narcissistic PD, Obsessive-Compulsive PD, and Schizotypal PD from the perspectives of Section II (PDQ-4) and Section III (PID-5) PD models, as well as measures of functional impairment in interpersonal and intrapersonal domains. Pearson correlations showed associations between ratings of impairment and most Section II and Section III PDs and trait facets, with the exception of narcissistic PD. Hierarchical regression analyses revealed that Section III PDs added predictive validity beyond Section II PDs in predicting impairment, except narcissistic PD. These findings provide support both for the impairment criterion in the AMPD and for the association between trait-based PDs and impairment, and suggest that this trait-based measurement adds uniquely to the understanding of functional impairment.

ABSTRACT

OBJECTIVE: The five personality disorder trait domains in the proposed International Classification of Diseases, 11th edition and the Diagnostic and Statistical Manual of Mental Disorders, 5th edition are comparable in terms of Negative Affectivity, Detachment, Antagonism/Dissociality and Disinhibition. However, the International Classification of Diseases, 11th edition model includes a separate domain of Anankastia, whereas the Diagnostic and Statistical Manual of Mental Disorders, 5th edition model includes an additional domain of Psychoticism. This study examined associations of International Classification of Diseases, 11th edition and Diagnostic and Statistical Manual of Mental Disorders, 5th edition trait domains, simultaneously, with categorical personality disorders. METHOD: Psychiatric outpatients ( N = 226) were administered the Structured Clinical Interview for DSM-IV Axis II Personality Disorders Interview and the Personality Inventory for DSM-5. International Classification of Diseases, 11th edition and Diagnostic and Statistical Manual of Mental Disorders, 5th edition trait domain scores were obtained using pertinent scoring algorithms for the Personality Inventory for DSM-5. Associations between categorical personality disorders and trait domains were examined using correlation and multiple regression analyses. RESULTS: Both the International Classification of Diseases, 11th edition and the Diagnostic and Statistical Manual of Mental Disorders, 5th edition domain models showed relevant continuity with categorical personality disorders and captured a substantial amount of their information. As expected, the International Classification of Diseases, 11th edition model was superior in capturing obsessive-compulsive personality disorder, whereas the Diagnostic and Statistical Manual of Mental Disorders, 5th edition model was superior in capturing schizotypal personality disorder. CONCLUSION: These preliminary findings suggest that little information is 'lost' in a transition to trait domain models and potentially adds to narrowing the gap between Diagnostic and Statistical Manual of Mental Disorders, 5th edition and the proposed International Classification of Diseases, 11th edition model. Accordingly, the International Classification of Diseases, 11th edition and Diagnostic and Statistical Manual of Mental Disorders, 5th edition domain models may be used to delineate one another as well as features of familiar categorical personality disorder types. A preliminary category-to-domain 'cross walk' is provided in the article.

ABSTRACT

OBJECTIVE: Obsessive-compulsive personality disorder (OCPD) is defined as being overly controlling, rigid, orderly, and perfectionistic. At a definitional level, OCPD would appear to be highly related to the trait of Conscientiousness. The current study attempts to disentangle this relationship by examining the relationship at a facet level using multiple forms of OCPD assessment and using multiple reports of OCPD and personality. In addition, the relationship between OCPD and each Big Five trait was examined. METHOD: The study relied on a sample of 1,630 adults who completed self-reports of personality and OCPD. Informants and interviewers also completed reports on the targets. Bifactor models were constructed in order to disentangle variance attributable to each facet and its general factors. RESULTS: Across four sets of analyses, individuals who scored higher on OCPD tended to be more orderly and achievement striving, and more set in their ways, but less generally conscientious. OCPD was also related to select facets under each Big Five trait. Notably, findings indicated that OCPD has a strong interpersonal component and that OCPD tendencies may interfere with one's relationships with others. CONCLUSIONS: Findings suggest that OCPD's relationship with personality can be more precisely explained through its relationships with specific tendencies rather than general, higher-order traits.

ABSTRACT

Lack of inhibitory control is present in impulsive and compulsive personality traits. The Go/No-Go task is one of the most effective means to assess response inhibition measured by the ability to appropriately withhold responding to No-Go stimuli. The aim of this work was to study whether differences in performance of Go/No-Go task predicts differences in personality traits related to inhibitory control. For this purpose 63 healthy participants divided into two groups based on the median split of false alarms on the Go/No-Go task completed Barratt Impulsiveness Scale (BIS-11) and the Maudsley Obsessional Compulsive Questionnaire (MOCI). Results showed that participants with high false alarms (H-FA) displayed a high-risk strategy of responding, and higher scores in the MOCI Total and MOCI Checking subscale compared to participants with low false alarms (L-FA). The results show for the first time a relation between the execution of the Go/No-Go task and the MOCI scale. Surprisingly, no relation was found between the Go/No-Go task and the BIS-11 scale. Further studies are needed to define the heterogeneous constructs of compulsivity and impulsivity, and to improve the convergence of the clinical scales and the behavioral measures of these two personality traits.

ABSTRACT

INTRODUCTION: aim of the study was to evaluate the presence of the Obsessive Compulsive Personality Disorder (OCPeD) in Multiple System Atrophy (MSA), Progressive Supranuclear Palsy (PSP) and Essential Tremor (ET) and in a group of healthy subjects. METHODS: patients affected by MSA, PSP and ET diagnosed according to currently accepted diagnostic criteria and a group of healthy controls were enrolled in the study. Patients with cognitive impairment were excluded from the study. The Structured Clinical Interview for Personality Disorders-II (SCID-II) has been performed to evaluate the presence of personality disorders (PeDs). The diagnosis of OCPeD was confirmed by a psychiatric interview. RESULTS: fifteen MSA patients (8 men and 7 women; aged 62.9 ± 7.6 years), 14 PSP patients (8 men and 6 women; aged 69.8 ± 4.4 years), 16 ET patients (10 men and 6 women; aged 70.4 ± 6.4 years) and 20 healthy subjects (10 men and 10 women; aged 65.5 ± 6.0 years) were enrolled. OCPeD was recorded in 5 (35.7%) PSP patients, 2 (13.3%) MSA patients, 2 (12.5%) ET patient and 2 (10%) controls. CONCLUSION: a low frequency of OCPeD, close to those recorded in healthy subjects, was recorded in both MSA and ET patients. Conversely an higher frequency of OCPeD, similar to PD was found among PSP patients, supporting the possibility of an impairment of common basal ganglia network possibly involving the orbito-frontal circuits.

ABSTRACT

Biological explanations address not only proximal mechanisms (for example, the underlying neurobiology of obsessive-compulsive disorder), but also distal mechanisms (that is, a consideration of how particular neurobiological mechanisms evolved). Evolutionary medicine has emphasized a series of explanations for vulnerability to disease, including constraints, mismatch, and tradeoffs. The current paper will consider compulsive symptoms in obsessive-compulsive and related disorders and behavioral addictions from this evolutionary perspective. It will argue that while obsessive-compulsive disorder (OCD) is typically best conceptualized as a dysfunction, it is theoretically and clinically valuable to understand some symptoms of obsessive-compulsive and related disorders in terms of useful defenses. The symptoms of behavioral addictions can also be conceptualized in evolutionary terms (for example, mismatch), which in turn provides a sound foundation for approaching assessment and intervention.

ABSTRACT

Compulsive behaviors are driven by repetitive urges and typically involve the experience of limited voluntary control over these urges, a diminished ability to delay or inhibit these behaviors, and a tendency to perform repetitive acts in a habitual or stereotyped manner. Compulsivity is not only a central characteristic of obsessive-compulsive disorder (OCD) but is also crucial to addiction. Based on this analogy, OCD has been proposed to be part of the concept of behavioral addiction along with other non-drug-related disorders that share compulsivity, such as pathological gambling, skin-picking, trichotillomania and compulsive eating. In this review, we investigate the neurobiological overlap between compulsivity in substance-use disorders, OCD and behavioral addictions as a validation for the construct of compulsivity that could be adopted in the Research Domain Criteria (RDoC). The reviewed data suggest that compulsivity in OCD and addictions is related to impaired reward and punishment processing with attenuated dopamine release in the ventral striatum, negative reinforcement in limbic systems, cognitive and behavioral inflexibility with diminished serotonergic prefrontal control, and habitual responding with imbalances between ventral and dorsal frontostriatal recruitment. Frontostriatal abnormalities of compulsivity are promising targets for neuromodulation and other interventions for OCD and addictions. We conclude that compulsivity encompasses many of the RDoC constructs in a trans-diagnostic fashion with a common brain circuit dysfunction that can help identifying appropriate prevention and treatment targets.

ABSTRACT

Compulsivity has been recently characterized as a manifestation of an imbalance between the brain׳s goal-directed and habit-learning systems. Habits are perhaps the most fundamental building block of animal learning, and it is therefore unsurprising that there are multiple ways in which the development and execution of habits can be promoted/discouraged. Delineating these neurocognitive routes may be critical to understanding if and how habits contribute to the many faces of compulsivity observed across a range of psychiatric disorders. In this review, we distinguish the contribution of excessive stimulus-response habit learning from that of deficient goal-directed control over action and response inhibition, and discuss the role of stress and anxiety as likely contributors to the transition from goal-directed action to habit. To this end, behavioural, pharmacological, neurobiological and clinical evidence are synthesised and a hypothesis is formulated to capture how habits fit into a model of compulsivity as a trans-diagnostic psychiatric trait.

ABSTRACT

Obsessive compulsive disorder (OCD) as well as related disorders such as body dysmorphic disorder, tic disorder, and trichotillomania are all common and often debilitating. Although treatments are available, more effective approaches to these problems are needed. Thus this review article presents what is currently known about OCD and related disorders and suggests that understanding OCD more broadly as a compulsive disorder may allow for more effective treatment options. Toward that goal, the review presents new models of psychopharmacology and psychotherapy, as well as new brain stimulation strategies. Treatment advances, grounded in the neuroscience, have promise in advancing treatment response for OCD as well as other disorders of compulsivity.

ABSTRACT

Prader-Willi syndrome (PWS) is a rare genetic disorder associated with distinct abnormal behaviors including hyperphagia, profound social deficits, and obsessive-compulsive tendencies. PWS males showed reduced oxytocin receptor (OTR) gene expression and density in the hypothalamic paraventricular nucleus that may play a role in PWS psychopathology. Oxytocin is an anorexigenic neuropeptide similar to vasopressin that is associated with social cognition and obsessive-compulsive behavior. To evaluate oxytocin biology in PWS, we examined overnight fasting plasma oxytocin levels in 23 children with PWS (mean ± SD age: 8.2 ± 2.0 year) having genetic confirmation and 18 age matched healthy unrelated siblings without PWS (mean ± SD age: 8.2 ± 2.3 year) and a similar gender ratio under the same clinical assessments, specimen processing and laboratory conditions. Multiplex immune assays were carried out using the Milliplex Human Neuropeptide Magnetic panel and the Luminex system. Natural log-transformed oxytocin levels were analyzed using general linear model adjusting for diagnosis, gender, age and body mass index (BMI). Oxytocin plasma levels were significantly elevated in children with PWS (168 ± 121 pg/ml) compared with unrelated and unaffected siblings without the diagnosis of PWS (64.8 ± 83.8 pg/ml, F = 8.8, P < 0.01) and the diagnosis of PWS predicted oxytocin level (F = 9.5, P < 0.003) in controlled regression analysis with an overall model fit R(2) = 0.33 (P < 0.01). The symptoms of hyperphagia, anxiety and repetitive behaviors classically seen in PWS may be related to the disruption of oxytocin responsivity or feedback in the hypothalamic paraventricular nucleus possibly influencing vasopressin signaling. Further study is needed to characterize oxytocin function in PWS.

ABSTRACT

Compulsivity is associated with alterations in the structure and the function of parallel and interacting brain circuits involved in emotional processing (involving both the reward and the fear circuits), cognitive control, and motor functioning. These brain circuits develop during the pre-natal period and early childhood under strong genetic and environmental influences. In this review we bring together literature on cognitive, emotional, and behavioral processes in compulsivity, based mainly on studies in patients with obsessive-compulsive disorder and addiction. Disease symptoms normally change over time. Goal-directed behaviors, in response to reward or anxiety, often become more habitual over time. During the course of compulsive disorders the mental processes and repetitive behaviors themselves contribute to the neuroplastic changes in the involved circuits, mainly in case of chronicity. On the other hand, successful treatment is able to normalize altered circuit functioning or to induce compensatory mechanisms. We conclude that insight in the neurobiological characteristics of the individual symptom profile and disease course, including the potential targets for neuroplasticity is an unmet need to advance the field.

ABSTRACT

The term 'addiction' was traditionally used in relation to centrally active substances, such as cocaine, alcohol, or nicotine. Addiction is not a unitary construct but rather incorporates a number of features, such as repetitive engagement in behaviours that are rewarding (at least initially), loss of control (spiralling engagement over time), persistence despite untoward functional consequences, and physical dependence (evidenced by withdrawal symptoms when intake of the substance diminishes). It has been suggested that certain psychiatric disorders characterized by maladaptive, repetitive behaviours share parallels with substance addiction and therefore represent 'behavioural addictions'. This perspective has influenced the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), which now has a category 'Substance Related and Addictive Disorders', including gambling disorder. Could other disorders characterised by repetitive behaviours, besides gambling disorder, also be considered 'addictions'? Potential examples include kleptomania, compulsive sexual behaviour, 'Internet addiction', trichotillomania (hair pulling disorder), and skin-picking disorder. This paper seeks to define what is meant by 'behavioural addiction', and critically considers the evidence for and against this conceptualisation in respect of the above conditions, from perspectives of aetiology, phenomenology, co-morbidity, neurobiology, and treatment. Research in this area has important implications for future diagnostic classification systems, neurobiological models, and novel treatment directions.
