Shivakumar AB, Kumari S, Mehak SF, Gangadharan G. Compulsive-like Behaviors in Amyloid-β 1-42-Induced Alzheimer's Disease in Mice Are Associated With Hippocampo-cortical Neural Circuit Dysfunction. BIOLOGICAL PSYCHIATRY GLOBAL OPEN SCIENCE 2023; 3:773-784.

Abstract
Background In addition to memory deficits, patients with Alzheimer's disease (AD) experience neuropsychiatric disturbances. Recent studies have suggested the association of obsessive-compulsive disorder with the early stages of AD. However, there is a lack of understanding of the neurobiological underpinnings of compulsive-like behaviors at the neuronal circuit level and their relationship with AD. Methods We have addressed this issue in an amyloid-β 1-42-induced mouse model of AD by studying compulsive-like behaviors. Next, we compared the hippocampal and medial prefrontal cortex (mPFC) local field potential pattern and coherence between these regions of control and AD mice. We also assessed the expression pattern of acetylcholine and glutamatergic signaling in these regions, using quantitative polymerase chain reaction. Results Our findings show that AD mice exhibit compulsive-like behaviors, as evidenced by enhanced marble burying, nest building, and burrowing. Furthermore, AD mice exhibited hippocampo-cortical circuit dysfunction demonstrated by decreased power of rhythmic oscillations at the theta (4-12 Hz) and gamma (25-50 Hz) frequencies in the hippocampus and mPFC, two functionally interconnected brain regions involved both in AD and compulsive behaviors. Importantly, coherence between the hippocampus and mPFC in the theta band of AD animals was significantly reduced. Furthermore, we found reduced cholinergic and glutamatergic neurotransmission in the hippocampus and mPFC of AD mice. Conclusions We conclude that the hippocampo-cortical functional alterations may play a significant role in mediating the compulsive-like behaviors observed in AD mice. These findings may help in understanding the underlying circuit mechanisms of obsessive-compulsive disorder-like phenotypes associated with AD.

Abstract
Protein Tyrosine Phosphatase receptor type D (PTPRD) is a member of the protein tyrosine phosphatase family that mediates cell adhesion and synaptic specification. Genetic studies have linked Ptprd to several neuropsychiatric phenotypes, including Restless Leg Syndrome (RLS), opioid abuse disorder, and antipsychotic-induced weight gain. Genome-wide association studies (GWAS) of either pediatric obsessive-compulsive traits, or Obsessive-Compulsive Disorder (OCD), have identified loci near PTPRD as genome-wide significant, or strongly suggestive for this trait. We assessed Ptprd wild-type (WT), heterozygous (HT), and knockout (KO) mice for behavioral dimensions that are altered in OCD, including anxiety and exploration (open field test, dig test), perseverative behavior (splash-induced grooming, spatial d), sensorimotor gating (prepulse inhibition), and home cage goal-directed behavior (nest building). No effect of genotype was observed in any measure of the open field test, dig test, or splash test. However, Ptprd KO mice of both sexes showed impairments in nest building behavior. Finally, female, but not male, Ptprd KO mice showed deficits in prepulse inhibition, an operational measure of sensorimotor gating that is reduced in female, but not male, OCD patients. Our results indicate that constitutive lack of Ptprd may contribute to the development of certain domains that are altered OCD, including goal-directed behavior, and reduced sensorimotor gating specifically in females.

Abstract
BACKGROUND Personality traits may predict antidepressant discontinuation and response. However, previous studies were rather small, only explored a few personality traits and did not include adverse drug effects nor the interdependency between antidepressant discontinuation patterns and response. METHODS GENDEP included 589 patients with unipolar moderate-severe depression treated with escitalopram or nortriptyline for 12 weeks. Seven personality dimensions were measured using the self-reported 240-item Temperament and Character Inventory-Revised (TCI-R). We applied Cox proportional models to study discontinuation patterns, logistic and linear regression to investigate response and remission after 8 and 12 weeks, and mixed-effects linear models regarding time-varying treatment response and adverse drug reactions. RESULTS Low harm avoidance, low cooperativeness, high self-transcendence and high novelty seeking were associated with higher risks for antidepressant discontinuation, independent of depressed mood, adverse drug reactions, drug, sex and age. Regression analyses showed that higher novelty seeking and cooperativeness scores were associated with a greater likelihood of response and remission after 8 and 12 weeks, respectively, but we found no correlations with response in the mixed-effects models. Only high harm avoidance was associated with more self-reported adverse effects. CONCLUSIONS This study, representing the largest investigation between several personality traits and response to two different antidepressants, suggests that correlations between personality traits and antidepressant treatment response may be confounded by differential rates of discontinuation. Future trials on personality in the treatment of depression need to consider this interdependency and study whether interventions aiming at improving compliance for some personality types may improve response to antidepressants.

Abstract
Many organisms rely on a capacity to rapidly replicate, disperse, and evolve when faced with uncertainty and novelty. But mammals do not evolve and replicate quickly. They rely on a sophisticated nervous system to generate predictions and select responses when confronted with these challenges. An important component of their behavioral repertoire is the adaptive context-dependent seeking or avoiding of perceptually novel objects, even when their values have not yet been learned. Here, we outline recent cross-species breakthroughs that shed light on how the zona incerta (ZI), a relatively evolutionarily conserved brain area, supports novelty-seeking and novelty-related investigations. We then conjecture how the architecture of the ZI's anatomical connectivity - the wide-ranging top-down cortical inputs to the ZI, and its specifically strong outputs to both the brainstem action controllers and to brain areas involved in action value learning - place the ZI in a unique role at the intersection of cognitive control and learning.

Abstract
The aim of this study was to evaluate the changes in temperament, character, and defense mechanisms with the treatment and remission in patients with major depressive disorder. The study was designed as a longitudinal observational follow-up study of patients with repeated measures at 0, 12, and 36 weeks. In baseline comparisons, the major depression group showed higher harm avoidance and novelty seeking scores and lower self-directness and mature defense styles scores compared with healthy controls. In the follow-up, temperament dimensions and neurotic defenses remained unchanged, mature defense styles and self-directness revealed significant increase, and immature defense styles revealed significant decrease. Although there was no significant difference in the defense styles, harm avoidance and novelty seeking scores remained higher in MDD patients compare with healthy controls in 36 weeks. Our findings regarding continuation of hierarchically upward improvement in defense mechanism after the remission may support importance of treatment after remission.

Abstract
AbstractPurposeTo compare patterns of temperament and character and the prevalence of Obsessive-Compulsive Personality Disorder (OCPD) and OCPD traits in parents of children with OCD and parents of healthy controls.MethodsTCI and SCID-II were administered to 63 parents of 32 children with OCD and 63 parents of age- and sex-matched controls with no psychiatric diagnosis. Interviewers were not blind to proband status. Personality dimension scores and frequencies of OCPD criteria in both groups were compared after excluding parents with a diagnosis of OCD. Relationships between TCI dimensions and OCPD symptoms in parents and the clinical characteristics of OCD children were also studied.ResultsParents of OCD children presented significantly higher scores in harm avoidance and lower scores in self-directedness, cooperativeness and reward dependence than parents of healthy children. A higher incidence of OCPD was found in parents of probands (p < 0.02). Hoarding, perfectionism and preoccupation with details were significantly more frequent in parents of OCD children. Counting, ordering and cleaning compulsions in OCD children predicted elevated odds of perfectionism and rigidity in their parents.ConclusionsThe existence of the dimensional personality profile associated with OCD in parents of children with OCD and the higher number of OCPD criteria in these parents in comparison to parents of healthy children highlight the importance of the role of personality factors in familial OCD.

Abstract
Reinforcement Sensitivity Theory (RST) posits that individual differences in reward and punishment processing predict differences in cognition, behavior, and psychopathology. We performed a quantitative review of the relationships between reinforcement sensitivity, depression and anxiety, in two separate sets of analyses. First, we reviewed 204 studies that reported either correlations between reinforcement sensitivity and self-reported symptom severity or differences in reinforcement sensitivity between diagnosed and healthy participants, yielding 483 effect sizes. Both depression (Hedges' g = .99) and anxiety (g = 1.21) were found to be high on punishment sensitivity. Reward sensitivity negatively predicted only depressive disorders (g = -.21). More severe clinical states (e.g., acute vs remission) predicted larger effect sizes for depression but not anxiety. Next, we reviewed an additional 39 studies that reported correlations between reinforcement sensitivity and both depression and anxiety, yielding 156 effect sizes. We then performed meta-analytic structural equation modeling to simultaneously estimate all covariances and control for comorbidity. Again we found punishment sensitivity to predict depression (β = .37) and anxiety (β = .35), with reward sensitivity only predicting depression (β = -.07). The transdiagnostic role of punishment sensitivity and the discriminatory role of reward sensitivity support a hierarchical approach to RST and psychopathology.

Abstract
BTB/POZ domain-containing 3 (BTBD3) was identified as a potential risk gene in the first genome-wide association study of obsessive-compulsive disorder (OCD). BTBD3 is a putative transcription factor implicated in dendritic pruning in developing primary sensory cortices. We assessed whether BTBD3 also regulates neural circuit formation within limbic cortico-striato-thalamo-cortical circuits and behaviors related to OCD in mice. Behavioral phenotypes associated with OCD that are measurable in animals include compulsive-like behaviors and reduced exploration. We tested Btbd3 wild-type, heterozygous, and knockout mice for compulsive-like behaviors including cage-mate barbering, excessive wheel-running, repetitive locomotor patterns, and reduced goal-directed behavior in the probabilistic learning task (PLT), and for exploratory behavior in the open field, digging, and marble-burying tests. Btbd3 heterozygous and knockout mice showed excessive barbering, wheel-running, impaired goal-directed behavior in the PLT, and reduced exploration. Further, chronic treatment with fluoxetine, but not desipramine, reduced barbering in Btbd3 wild-type and heterozygous, but not knockout mice. In contrast, Btbd3 expression did not alter anxiety-like, depression-like, or sensorimotor behaviors. We also quantified dendritic morphology within anterior cingulate cortex, mediodorsal thalamus, and hippocampus, regions of high Btbd3 expression. Surprisingly, Btbd3 knockout mice only showed modest increases in spine density in the anterior cingulate, while dendritic morphology was unaltered elsewhere. Finally, we virally knocked down Btbd3 expression in whole, or just dorsal, hippocampus during neonatal development and assessed behavior during adulthood. Whole, but not dorsal, hippocampal Btbd3 knockdown recapitulated Btbd3 knockout phenotypes. Our findings reveal that hippocampal Btbd3 expression selectively modulates compulsive-like and exploratory behavior.

Abstract
There is a lack of research on the relation between obsessive-compulsive disorder (OCD) and resilience. Dispositional resilience, as described and defined in literature on hardiness, consists of three facets, namely beliefs about having control in everyday living, having a sense of purpose or commitment, and a positive attitude toward challenges. This study explores associations between dispositional resilience (measured with the Dispositional Resilience Scale (DRS-15-R)), symptom severity, and treatment outcome in a sample of 89 patients treated with concentrated exposure therapy (cET), and compares the findings with scores from two reference groups (students and soldiers). The patient group had significantly lower resilience scores than the two reference groups. Weak correlations were observed between dispositional resilience and OCD symptoms. Differences in dispositional resilience were weakly related to remission status at follow-up (odds ratio of 1.11). Furthermore, resilience improved from pre- to post-treatment (Cohen's d of 0.65). Our results imply that patients' initial resilience score does not hinder nor facilitate treatment effects to a great extent in this format of ERP treatment.

Abstract
BACKGROUND Temperament and mental illness are thought to represent varying degrees along the same continuum of neurotransmitter imbalances. A taxonomy of temperament could provide the basis for a new taxonomy of mental illness. Most popular models of temperament, being based heavily on emotionality traits, show very poor ability to discriminate between mental disorders. The main goal of this study was to examine whether a temperament model based on modern neurophysiology and possessing an extensive set of non-emotionality traits provides better discrimination between Major Depression (MD), Generalized Anxiety (GAD) and Comorbid MD and GAD, in comparison to emotionality-based temperament models. METHODS Using the Structure of Temperament Questionnaire, the temperament profiles of 687 individuals (396 clients of private psychiatric and psychological practice, and 291 control subjects) were compared across four adult age groups (18-24, 25-45, 46-65, 66-84). RESULTS MD and GAD appear to be accurately distinguished by the traits of Motor Endurance and Motor Tempo (much lower values in depression), and Neuroticism (much higher value in anxiety). Comorbids can be distinguished based on a significant decrease in the traits of Plasticity, Intellectual Endurance, Sensitivity to Probabilities, and increased Impulsivity. These effects seemed independent of age and gender. CONCLUSIONS The results suggest the benefits of including non-emotionality-related traits and the usefulness of a functional approach to both taxonomy of temperament and classification of mental disorders.

Abstract
We describe the Temperament and Character Inventory personality traits, demographic features, physical and mental health variables associated with hoarding behaviour in a random community sample of midlife participants in New Zealand. A sample of 404 midlife participants was recruited to a study of ageing. To assess hoarding behaviours participants completed the Savings Inventory-Revised (SI-R), personality was assessed by the Temperament and Character Inventory and self-reported health was measured by the Short Form-36v2 (SF-36v2). Other measures were used to assess socio-demographic variables and current mental disorders. Participants were split into four groups by SI-R total score (scores: 0–4, 5–30, 31–41 and >41). Those who scored >41 on the SI-R were classified as having pathological hoarding. Trend tests were calculated across the four hoarding groups for socio-demographic, personality, mental and physical health variables. SI-R scores ranged from 0 to 58. The prevalence of pathological hoarding was 2.5% and a further 4% reported sub-clinical symptoms of hoarding. Higher hoarding behaviour scores were related to higher Temperament and Character Inventory scores for Harm Avoidance and lower scores for Self-directedness. Persistence and Cooperativeness scores were lower too but to a lesser extent. Trend analysis revealed that those with higher hoarding behaviour scores were more likely to be single, female, unemployed, receive income support, have a lower socio-economic status, lower household income and have poorer self-reported mental health scores. Current depression rates were considerably higher in the pathological hoarding group. Increasing SI-R hoarding behaviour scores were associated with higher scores of negative affect (Harm Avoidance) and lower scores of autonomy (Self-directedness). Those with pathological hoarding or sub-clinical symptoms of hoarding also reported widespread mental and socio-economic problems. In this study it is clear to see the physical, mental and socio-economic problems experienced by those achieving the highest hoarding scores. The prevalence of pathological hoarding was 2.5%, similar to the prevalence reported by other studies. The personality traits associated with hoarding behaviours are discussed.

Abstract
The current study investigates the effect of adolescent harm avoidance (HA) on maladaptive cognitive emotion regulation strategies (mCER) in early adulthood. The mediating role of inhibitory control and the moderating effect of gender on this link were also examined. Longitudinal data from 261 adolescents (147 female) were collected in three phases (T0, T1 and T2) over approximately 10 years. Results revealed that, after controlling for HA in adulthood (T2), female adolescents' HA (T0) significantly predicted mCER strategies after 10 years (T2), whereas male adolescents' HA only predicted catastrophizing. In addition, attentional impulsivity (T1) significantly mediated the relation between HA and mCER, though only among women. There was no significant indirect effect for emotional interference and stop-signal reaction time. Results revealed gender and measure specific associations between HA and inhibitory control and suggest that HA could induce inhibitory deficits leading to mCER.

Abstract
Studies of temperament profiles in patients with mental disorders mostly focus on emotionality-related traits, although mental illness symptoms include emotional and nonemotional aspects of behavioral regulation. This study investigates relationships between 12 temperament traits (9 nonemotionality and 3 emotionality related) measured by the Structure of Temperament Questionnaire and four groups of clinical symptoms (depression, anxiety, antisociality, and dominance-mania) measured by the Personality Assessment Inventory. The study further examines age differences in relationships among clinical symptoms and temperament traits. Intake records of 335 outpatients and clients divided into four age groups (18–25, 26–45, 46–65, and 66–85) showed no significant age differences on depression scales; however, the youngest group had significantly higher scores on Anxiety, Antisocial Behavior, Dominance, and Thought Disorders scales. Correlations between Personality Assessment Inventory and Structure of Temperament Questionnaire scales were consistent with Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, descriptors showing strong concurrent validity. Several age differences on temperament scales are also reported. Results show the benefits of differentiation between physical, social-verbal, and mental aspects of activities, as well as differentiation between dynamical, orientational, and energetic aspects in studying mental illness and temperament.

Abstract
Temperament traits and mental illness have been linked to varying degrees of imbalances in neurotransmitter systems of behavior regulation. If a temperament model has been carefully structured to reflect weak imbalances within systems of behavior regulation, then in the presence of mental illness, these profiles should exhibit distinct patterns consistent with symptoms of mental illness. In contrast to other temperament models used in studies of anxiety disorders, the Functional Ensemble of Temperament (FET) model differentiates not only between emotionality traits, but also between traits related to physical, social-verbal and mental aspects of behavior. This paper analyzed the predictions of the FET model, which maps 12 functional aspects of behavior to symptoms of generalized anxiety disorder (GAD) as described in the DSM/ICD. As an example, the paper describes a study of the coupling of sex, age and temperament traits with GAD using the FET framework. The intake records of 116 clients in treatment with confirmed diagnosis of GAD in a private psychological practice were compared using ANOVA against records of 146 healthy clients using their scores on the FET-based questionnaire, in age groups 17–24, 25–45, 46–65. Patients with GAD in all age groups reported significantly lower Social Endurance, Social Tempo, Probabilistic reasoning (but not in physical aspects of behavior) and higher Neuroticism than healthy individuals, however, no effects on the scales of Motor Endurance or Tempo were found. These findings show the benefits of differentiation between motor-physical and social-verbal aspects of behavior in psychological assessment of mental disorders.

Abstract
Even though obsessive-compulsive disorders (OCD) and anxiety disorders (AD) have been separated in the taxonomy adopted by the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, many issues remain concerning the physiopathological similarities and differences between those categories. Our objective was therefore to explore and compare their personality and emotional features, with the assumption that the distinction of two independent spectrums should imply the existence of two partially distinct temperamental profiles. We used the Temperament and Character Inventory (TCI-R) and the Positive and Negative Emotionality (PNE) scale to compare two groups of patients with OCD (n=227) or AD (n=827). The latter group included patients with social anxiety disorder, panic disorder, agoraphobia, and generalized anxiety disorder. Most temperament, character and emotionality measures showed no significant differences between both groups. In the personality measures results, only the self-directedness score (TCI-R) was significantly lower in OCD patients but this difference was not significant when the comparison was adjusted for the depressive scale score and age. Only lower PNE positive affects scores were obtained in OCD patients in the adjusted comparisons. These findings suggest that OCD and AD are not really distinguishable from the point of view of associated personality traits.

Abstract
AIM The aim of this study is to evaluate the differences in obsessional beliefs between patients with major depressive disorder (MDD) and matched healthy controls using the obsessive-beliefs questionnaire (OBQ). METHODS The study sample included 74 outpatients with MDD and 74 healthy subjects. The two groups were matched for age, gender, and education level. The diagnoses were based on the Diagnostic and Statistical Manual of Mental Disorder (DSM-IV). The severity of depression was measured with the Hamilton Depression Rating Scale (HAM-D). All participants filled out the 44-item OBQ. RESULTS The total and subscale OBQ scores [Responsibility/Threat Estimation (RT), Perfectionism/Certainly (PC), and Importance/Control of Thoughts (ICT)], were significantly higher in patients with MDD than those of the control group. There was a positive correlation between HAM-D scores and the OBQ subscale scores (RT, PC, and ICT) in the patients. CONCLUSION Obsessional beliefs appear to be related to MDD.

Abstract
OBJECTIVE Not enough is known about which patients suffering from major depressive disorder benefit from antidepressant drug treatment. Individual temperament is relatively stable over a person's lifespan and is thought to be largely biologically predefined. We assessed how temperament profiles are related to depression and predict the efficacy of antidepressant treatment. METHODS We recruited one hundred Finnish outpatients (aged 19 to 72) suffering from major depressive disorder, of whom 86 completed the 6-week study. We assessed their temperament features with the Temperament and Character Inventory and used cluster analysis to determine the patient's temperament profile. We also categorized the patients according to the vegetative symptoms of major depressive disorder. RESULTS There was an association between skewed temperament profile and severity of major depressive disorder, but the temperament profiles alone did not predict antidepressant treatment response. Those with higher baseline vegetative symptoms score had modest treatment response. Our model with baseline Montgomery Åsberg Depression Rating Scale (MADRS) vegetative symptoms, age and temperament clusters as explanatory variables explained 20% of the variance in the endpoint MADRS scores. CONCLUSION The temperament clusters were associated both with severity of depression and antidepressive treatment response of depression. The effect of the temperament profile alone was modest but, combined with vegetative symptoms of depression, their explanatory power was more marked suggesting that there could be an association of these two in the biological basis of MDD.

Abstract
OBJECTIVES To evaluate temperament and character traits using the Junior Temperament and Character Inventory (JTCI) in children and adolescents with major depressive disorder (MDD) in comparison with healthy control subjects (HC), and to verify if comorbidity with disruptive behavioral disorders and being currently depressed influence JTCI scores. METHODS A case-control study comprising 41 MDD children/adolescents matched to 40 HC by gender and age (8-17years). All participants were assessed diagnostically with the Kiddie Schedule for Affective Disorders and Schizophrenia - Present and Lifetime (K-SADS-PL). Temperament and character traits were measured with the parent and child versions of JTCI, and depression was evaluated with the Children's Depression Rating Scale (CDRS). RESULTS According to child and parent data, MDD subjects had significantly higher scores on harm avoidance and novelty seeking, and lower scores on reward dependence, persistence, self-directedness and cooperativeness compared with HC. According to parent data only, MDD subjects significantly differed from HC on self-transcendence (lower spirituality scores and higher fantasy scores). Comorbidity with disruptive behavioral disorders exerted influence on almost all dimensions, in general increasing the mean differences between MDD and HC subjects. Also, being currently depressed did not influence the results, except for reward dependence according to parent data. LIMITATIONS The cross-sectional nature of the study and its limited sample size. CONCLUSIONS MDD children/adolescents have a different temperament and character profile compared to HC subjects. This study supports previous findings of trait-like characteristics of harm avoidance and self-directedness.

Abstract
BACKGROUND An increasingly growing area of empirical research has found consistent links between anger, depression, and temperament and character domains of personality, separately. However, precise nature of these relationships remains still unclear, and little is known about its underlying processes. OBJECTIVES The aim of our explorative research was to conduct a more detailed investigation into the relationships among depression, anger trait, and personality characteristics based on Cloninger's 7-factor personality theory in healthy individuals. METHOD In this preliminary study, 230 Italian undergraduates were investigated by using the Temperament and Character Inventory-Revised, the State-Trait Anger Expression Inventory-2, and the Beck Depression Inventory-II. Depression and cooperativeness were expected to have a negative and significant relationship and separate relationships with the trait-anger. Theoretically, a new hypothesis was that the trait-anger would mediate the relationship between depression and cooperativeness. RESULTS Zero-order and partial correlations and a path analysis based on Baron and Kenny's method (J Pers Soc Psychol.1986;51:1173-1182) for calculating multiple regression analyses were calculated. Consistent with the hypotheses, cooperativeness and depression were strongly associated; the trait-anger was significantly associated with both cooperativeness and depression, and the mediation model fit the data. CONCLUSIONS Behaviors related to the trait-anger could help to explain how depression and reduced cooperativeness are related each other.

Abstract
This article reports on a meta-analysis of Cloninger's temperament dimensions (novelty seeking, harm avoidance, reward dependence, and persistence) in individuals with lifetime psychiatric disorders compared with controls and on interdisorder comparisons between these disorders. Nine disorders from 75 studies were included in the meta-analyses. The most consistent feature was elevated harm avoidance: compared with the controls, harm avoidance was higher in all diagnostic groups studied except for those with alcohol use disorders. The increase in effect sizes in harm avoidance scores varied from a very large (d = 2.66) in social phobia to a small effect (effect size, d = 0.29) in alcohol use disorders. In other dimensions, differences between cases and controls were relatively small. However, in pairwise comparisons, notable differences also in other dimensions emerged: in novelty seeking, the lowest scores were in social phobia (d = -0.87) and the highest in bulimia nervosa (d = 0.33); in reward dependence, the lowest scores were in schizophrenia (d = -0.36) and the highest in social phobia (d = 0.12); and in persistence, the lowest scores were in social phobia (d = -0.30) and the highest in anorexia nervosa (d = 0.49). The provided data should be taken into account in the future studies on suggestive vulnerability markers for psychiatric morbidity.

Abstract
Objective. To examine the effects of temperament and character profiles on state and trait depression and anxiety in a Japanese youth population. Method. Japanese university students were solicited for participation in a two-wave study, with assessments performed at Time 1 (T1) and Time 2 (T2), separated by a five-month interval. A total of 184 students completed the Japanese version of the temperament and character inventory (TCI) at T1 and the Hospital Anxiety and Depression Scale (HADS) at T1 and T2. We posited two latent variables, trait depression and anxiety, composed of the T1 and T2 HADS depression and anxiety scores, respectively. We also posited that temperament domain traits would predict character domain traits, and that all the personality traits would be linked to trait depression and anxiety and also predict T2 depression and anxiety. Results. Structural regression modeling showed that (1) only high Novelty Seeking predicted T2 Anxiety score, (2) trait depression and anxiety were linked to high harm avoidance and low self-directedness, and (3) trait depression was linked to high self-transcendence whereas trait anxiety was linked to low reward dependence, persistence, and cooperativeness. Conclusion. The characteristic associations between TCI subscales and depression and anxiety were limited to the trait rather than state aspects of depression and anxiety.

Abstract
BACKGROUND Very few longitudinal studies have evaluated prospective neurodevelopmental and psychosocial risk factors for obsessive-compulsive disorder (OCD). Furthermore, despite the heterogeneous nature of OCD, no research has examined risk factors for its primary symptom dimensions, such as contamination/washing. METHOD Potential risk factors for symptoms or diagnosis of OCD in adulthood and for specific adult obsessive-compulsive (OC) symptom dimensions were examined in the Dunedin Study birth cohort. The presence of obsessions and compulsions and psychological disorders was assessed using the Diagnostic Interview Schedule (DIS) at ages 26 and 32 years. Individuals with a diagnosis of OCD at either age (n=36) were compared to both a healthy control group (n=613) and an anxious control group (n=310) to determine whether associations between a risk factor and an OCD diagnosis were specific. RESULTS Childhood neurodevelopmental, behavioral, personality and environmental risk factors were associated with a diagnosis of OCD and with OC symptoms at ages 26 and 32. Social isolation, retrospectively reported physical abuse and negative emotionality were specific predictors of an adult OCD diagnosis. Of note, most risk factors were associated with OC symptoms in adulthood and several risk factors predicted specific OCD dimensions. Perinatal insults were linked to increased risk for symmetry/ordering and shameful thoughts dimensions, whereas poor childhood motor skills predicted the harm/checking dimension. Difficult temperament, internalizing symptoms and conduct problems in childhood also predicted specific symptom dimensions and lower IQ non-specifically predicted increased risk for most dimensions. CONCLUSIONS The current findings underscore the need for a dimensional approach in evaluating childhood risk factors for obsessions and compulsions.

Abstract
BACKGROUND Whether temperament and character differ between bipolar disorder (BD) and major depressive disorder (MDD) patients and general population subjects, or between BD I and BD II patients, remains unclear. METHOD BD patients (n=191) from the Jorvi Bipolar Study and MDD patients (n=266) from the Vantaa Depression Study (VDS) and the Vantaa Primary Care Depression Study were interviewed at baseline, at 6 and 18 months, and in the VDS at 5 years. A general population comparison group (n=264) was surveyed by mail. BD patients' scores on the Temperament and Character Inventory-Revised were compared at an index interview, when levels of depression and mania were lowest, with scores of MDD patients and controls. BD I (n=99) and BD II (n=92) patients were compared. RESULTS Compared with controls, both BD and MDD patients had higher harm avoidance [odds ratio (OR) 1.027, p<0.001 and OR 1.047, p<0.001, respectively] and lower persistence (OR 0.983, p=0.006 and OR 0.968, p<0.001, respectively) scores. Moreover, BD patients had lower self-directedness (OR 0.979, p=0.003), MDD patients lower reward dependence (OR 0.976, p=0.002) and self-transcendence (OR 0.966, p<0.001) scores. BD patients scored lower in harm avoidance (OR 0.980, p=0.002) and higher in novelty seeking (OR 1.027, p<0.001) and self-transcendence (OR 1.028, p<0.001) than MDD patients. No differences existed between BD I and II patients. CONCLUSIONS The patterns of temperament and character dimensions differed less between BD and MDD patients, than patients from their controls. The most pronounced difference was higher novelty seeking in BD than MDD patients. The dimensions investigated are unlikely to differ between BD I and BD II patients.

Abstract
Objective. To examine the relations between personality traits and syndromes of depression in a nonclinical Chinese population. Method. We recruited 469 nonclinical participants in China. They completed the Chinese version temperament and character inventory (TCI) and self-rating depression scale (SDS). A structural equation model was used to rate the relation between seven TCI scales and the three SDS subscale scores (based on Shafer's meta-analysis of the SDS items factor analyses). This was based on the assumption that the three depression subscales would be predicted by the temperament and character subscales, whereas the character subscales would be predicted by the temperament subscales. Results. The positive symptoms scores were predicted by low self-directedness (SD), cooperativeness (C), reward dependence (RD), and persistence (P) as well as older age. The negative symptoms scores were predicted only by an older age. The somatic symptoms scores were predicted by high SD. Conclusion. Syndromes of depression are differentially associated with temperament and character patterns. It was mainly the positive symptoms scores that were predicted by the TCI scores. The effects of harm avoidance (HA) on the positive symptoms scores could be mediated by low SD and C.

Abstract
BACKGROUND The aims of this study were to evaluate the differences between personality traits of patients with obsessive-compulsive disorder (OCD) and normal controls using the Temperament and Character Inventory (TCI) and to examine the relationship of personality traits and the severity of obsessive-compulsive (OC) symptoms. We also aimed to examine the influence a particular personality trait might have on the 5 factor-analyzed symptom dimension scores of OCD. METHOD We recruited 130 patients with OCD and 185 age- and sex-matched normal controls. All subjects completed the TCI. Patients with OCD were assessed with the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Hamilton Depression Rating Scale, and the factor-analyzed symptom dimension scores from the Y-BOCS checklist. RESULTS Patients with OCD had higher harm avoidance scores and lower self-directedness (SD), reward dependence (RD), and cooperativeness (C) scores than the controls. Lower SD scores and lower C scores were associated with OC symptom severity measured by the Y-BOCS after adjusting for age and depression severity. Hoarding dimension of OC symptoms was associated with lower SD scores and higher persistence (P) scores after adjusting for age, OC symptom severity, and depression severity. CONCLUSIONS There were significant differences in TCI subscales between patients with OCD and controls. Particular personality traits may have an influence on the severity and the dimensions of OC symptoms.

Abstract
OBJECTIVE Personality dimension is considered as a risk factor of depression. This study was to compare aggression, impulsivity, hopelessness, and TCI (temperament and character dimensions) between patients with major depressive disorder (MDD) and normal controls. METHODS A total of 56 MDD patients and the same number of normal controls who were matched for age, gender, and education were recruited. All subjects completed the following questionnaires; Aggression Questionnaire (AQ), Beck Hopelessness Scale (BHS), Barratt Impulsiveness Scale, 11th Version (BIS-11), and Temperament and Character Inventory (TCI). RESULTS MDD patients were significantly higher scores in anger, hostility of AQ, BHS, motor impulsivity of BIS-11, and Harm Avoidances (HA) of TCI with all subscales of HA than normal controls, whereas novelty seeking 1 (NS1) (Exploratory of NS), Reward Dependence (RD) with RD3 (Attachment) . RD4 (Dependence), Self-Directedness (SD) with most subscales of SD, Cooperativeness (CO), and ST3 (Spiritual Acceptance) showed lower scores than normal controls. Moreover, BHS and HA, BIS and NS showed moderate positive correlation in MDD patients, while BHS and SD, HA and SD were negatively correlated. CONCLUSION The present study showed unique clinical features, especially personality dimensions of patients with MDD. Our results could be applicable to suggest treatment process and to predict one's prognosis for depression in that psychological properties are important for drug compliance and treatment response.

Abstract
With recent advances in understanding of the neuroscience of risk taking, attention is now turning to genetic factors that may contribute to individual heterogeneity in risk attitudes. In this paper we test for genetic associations with risk attitude measures derived from both the psychology and economics literature. To develop a long-term prospective study, we first evaluate both types of risk attitudes and find that the economic and psychological measures are poorly correlated, suggesting that different genetic factors may underlie human response to risk faced in different behavioral domains. We then examine polymorphisms in a spectrum of candidate genes that affect neurotransmitter systems influencing dopamine regulation or are thought to be associated with risk attitudes or impulsive disorders. Analysis of the genotyping data identified two single nucleotide polymorphisms (SNPs) in the gene encoding the alpha 4 nicotine receptor (CHRNA4, rs4603829 and rs4522666) that are significantly associated with harm avoidance, a risk attitude measurement drawn from the psychology literature. Novelty seeking, another risk attitude measure from the psychology literature, is associated with several COMT (catechol-O-methyl transferase) SNPs while economic risk attitude measures are associated with several VMAT2 (vesicular monoamine transporter) SNPs, but the significance of these associations did not withstand statistical adjustment for multiple testing and requires larger cohorts. These exploratory results provide a starting point for understanding the genetic basis of risk attitudes by considering the range of methods available for measuring risk attitudes and by searching beyond the traditional direct focus on dopamine and serotonin receptor and transporter genes.

Abstract
OBJECTIVE Comorbidity with personality disorders in obsessive-compulsive patients has been widely reported. About 40% of obsessive-compulsive patients do not respond to first line treatments. Nevertheless, there are no direct comparisons of personality traits between treatment-responsive and non-responsive patients. This study investigates differences in personality traits based on Cloninger's Temperament and Character Inventory scores between two groups of obsessive-compulsive patients classified according to treatment outcome: responders and non-responders. METHOD Forty-four responsive and forty-five non-responsive obsessive-compulsive patients were selected. Subjects were considered treatment-responsive (responder group) if, after having received treatment with any conventional therapy, they had presented at least a 40% decrease in the initial Yale-Brown Obsessive Compulsive Scale score, had rated "better" or "much better" on the Clinical Global Impressions scale; and had maintained improvement for at least one year. Non-responders were patients who did not achieve at least a 25% reduction in Yale-Brown Obsessive Compulsive Scale scores and had less than minimal improvement on the Clinical Global Impressions scale after having received treatment with at least three selective serotonin reuptake inhibitors (including clomipramine), and at least 20 hours of cognitive behavioral therapy. Personality traits were assessed using Temperament and Character Inventory. RESULTS Non-responders scored lower in self-directedness and showed a trend to score higher in persistence than responders did. CONCLUSION This study suggests that personality traits, especially self-directedness, are associated with poor treatment response in obsessive-compulsive patients.

Abstract
The present study evaluated whether different patterns of temperament may predict a different threshold of acceptability of obsessive-compulsive (OC) symptoms in adolescents. OC symptomatology was detected with the Leyton Obsessional Inventory-Child Version (LOI-CV) and temperament was assessed using the tridimensional personality questionnaire in 2,775 high-school students. According to the LOI-CV scores, the adolescents were classified as high interference (interfering, ego-dystonic symptoms) (HI), supernormal (noninterfering, ego-syntonic symptoms) (Sn) and controls (C) HI were 119 (4.3%), Sn 85 (3.1%) and C 2,571 (92.6%). The best predictor of belonging to HI or Sn groups was the temperament configuration of high Harm Avoidance (HA) and high Persistence (P). The feature that mainly distinguishes the two symptomatic groups were Novelty Seeking (NS) levels. Our data suggest that people characterized by pessimistic worry in anticipation of future problems, passive avoidant behaviour, rapid fatigability (high HA) and irresoluteness, ambitiousness, perseverance, perfectionism, enduring feelings of frustration (high P) might develop OC symptoms. Whether OC symptoms become ego-syntonic or ego-dystonic seems to mainly depend on NS levels: low NS might protect people (with the prevention of "exploratory and active behaviours" that may elicit loss of control on symptoms) from the development of interfering OC symptoms.

Abstract
Research on the relationship between personality factors and obsessive-compulsive disorder (OCD) has proved difficult to interpret due to conceptual problems including a lack of consensus on the model of personality employed as a framework as well as a failure to consider the clinical heterogeneity of the disorder. The aim of this study was to examine the dimensional personality profile associated with OCD and to determine whether any relationship exists between personality factors and clinical variables in a sample of 60 OCD outpatients who were administered Cloninger's Temperament and Character Inventory (TCI). The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Hamilton Depression Rating Scale (HDRS) and the Y-BOCS symptom checklist were used to assess the severity of obsessive-compulsive and depressive symptoms and the presence of the main OCD symptom dimensions. OCD patients showed significantly higher scores in harm avoidance and lower scores in novelty-seeking, self-directedness and cooperativeness than healthy subjects. These results remained unchanged when only pure OCD patients without comorbid psychiatric conditions were considered. Comorbid depressive symptoms and hoarding obsessions and compulsions were significantly associated with high harm avoidance scores. These results support the existence of a dimensional personality profile associated with OCD and characterized by high harm avoidance and low novelty-seeking, self-directedness and cooperativeness scores, but also emphasize the importance of considering the influence of comorbid clinical conditions or symptom subtypes in addressing the role of personality factors in OCD.

Abstract
Although the organic and psychosocial consequences of seizure disorders are thought to affect temperament and character patterns, these patterns in children with seizure disorders have not yet been investigated. We therefore investigated temperament and character patterns in Korean children with seizure disorders and their associations with seizure-related variables. The Korean version of the Junior Temperament and Character Inventory was used to assess temperament and character factors of 65 children with seizure disorders (32 boys, 33 girls; mean age, 10.6 +/- 1.8 years) and 65 healthy controls matched for age and sex. Children with seizure disorders showed higher harm avoidance, and lower persistence, self-directedness, and cooperativeness than controls. In children with seizure disorders, character factors such as self-directedness, cooperativeness, and self-transcendence were significantly associated with seizure type, and cooperativeness was correlated with seizure severity. Novelty seeking and self-directedness were correlated with paternal educational level and parental economic status, respectively. These findings suggest that children with seizure disorders have distinctive temperament and character patterns, with seizure type being the most influential factor modulating character patterns.

Abstract
BACKGROUND The personality dimensions of harm avoidance (HA) and self-directedness (SD), as measured by the Temperament and Character Inventory (TCI), have been widely associated with depression and there is preliminary evidence that they may represent trait markers for depression. However, many studies in this area are limited by the use of heterogeneous samples of depressed patients and by the confounding effect of depressed mood during personality testing. The current study compares TCI personality dimension scores in a group of euthymic young adults with recurrent early-onset major depressive disorder (RE-MDD) to well-matched euthymic controls. METHODS Fifty-two young adults with a past history of RE-MDD were recruited from consecutive referrals to a psychiatric clinic at a university health service. Eighty nine controls were also recruited. Euthymia was established in patients by a score of less than 9 on the Hamilton Rating Scale for Depression (HRSD) and in controls by a Becks Depression Inventory (BDI) score of less than 10. All participants completed the TCI-125. RESULTS Patients and controls were well matched in terms of sociodemographic profile. Euthymic RE-MDD patients scored significantly higher than controls on the temperament dimension of harm avoidance (HA; mean score 14.5 versus 7.8, p<0.0001) and significantly lower than controls on the character dimension of self-directedness (SD; mean score 14.1 versus 19.9, p<0.0001). Covariance analysis suggested that both HA and SD contributed independently to the familial risk of depression. LIMITATIONS Subjects and controls all came from relatively affluent social backgrounds-these findings may not generalise to more socioeconomically diverse populations. The possibility of a 'scarring effect' of depressive episodes on self-reported personality dimension scores cannot be excluded. CONCLUSIONS High HA and low SD represent trait markers for liability to recurrent major depressive disorder in young adults. Further research is needed to replicate these findings and to assess the contribution that the experience of depressive episodes makes to self-reported personality dimension scores.

Abstract
Recent factor-analytic studies involving over 2000 patients have reduced the symptoms of obsessive-compulsive disorder (OCD) into a few dimensions or potentially overlapping syndromes. Hoarding consistently emerged as a separate factor in all these studies. This study investigated the relationship between OCD symptom dimensions and normal personality traits in a sample of 56 OCD patients. They were administered the Sensitivity to Punishment and Sensitivity to Reward Questionnaire and the Eysenck Personality Questionnaire, derived from Gray's and Eysenck's personality models, respectively. The personality scores were correlated with previously identified symptom dimensions from the Yale-Brown Obsessive-Compulsive Scale Symptom Checklist (Y-BOCS-SC), controlling for overall illness severity. High scores on the hoarding dimension of the Y-BOCS-SC were positively correlated with scores on the Sensitivity to Punishment scale and negatively with Eysenck's Psychoticism scale. While high sensitivity to punishment is a personality feature common to many OCD patients, it is more strongly pronounced in patients with hoarding symptoms. These patients also appear to be less impulsive or novelty seeking as reflected by low scores on Eysenck's Psychoticism scale. High sensitivity to punishment and low novelty seeking in OCD hoarders might explain their poor compliance and response to conventional treatments, but this question needs to be explored further in a prospective treatment study.

Abstract
OBJECTIVE The present study examined the psychobiological Temperament and Character model of personality on obsessive-compulsive disorder (OCD) patients, as well as the relation of temperament and/or character dimensions on the severity of obsessive-compulsive symptoms. METHODS Fifty-four subjects diagnosed with OCD, were assessed with the Temperament and Character Inventory, the Yale-Brown Obsessive-Compulsive scale and the Hamilton Rating Scales for depression and anxiety. RESULTS Compared with controls, OCD subjects displayed increased harm avoidance and lower self-directedness and cooperativeness. Low self-directedness and high Hamilton depression scores were associated with increased severity of obsessive-compulsive symptoms. CONCLUSION The Temperament and Character profile of OCD patients characterized in the present study was in agreement with previous reports using the same personality model and can be linked to some of their behavioral features. Furthermore, our data provides support of the influence that some personality traits may have on the severity of OCD symptoms.

Abstract
In recent years a number of studies of personality have been performed in subjects with Eating Disorders (EDs) to investigate the clinical differences between controls and ED patients and among EDs subtypes, and its role in the development and course of symptoms. The Tridimensional Personality Questionnaire (TPQ) and the Temperament and Character Inventory (TCI) have been widely used at this purpose, allowing the description of specific temperament and character profiles for EDs. High Harm Avoidance (HA) and low Self-Directedness (SD) are shared by all EDs. Slight differences on some facets have been found among ED subgroups. Nevertheless, HA is influenced by mood and both high HA and low SD are personality traits shared by many mental disorders, whose specificity is rather low. Restrictor anorectics are characterized by high Persistence (P) and a relatively higher SD, and bulimics by higher Novelty Seeking (NS) and the lowest SD, while binge/purging and purging anorectics share some traits with anorexia and some with bulimia. Though current data justify the discrimination among anorexia subtypes, they are not in contrast with the thesis of a continuum in ED personality traits. Since some personality traits display a prognostic value with regard to therapy and clinical outcome, further studies are needed on treatments and prognostic factors in EDs. Moreover, studies attempting to define the neurobiological and genetic correlates of temperament should be supported by clinical pharmacological trials.

Abstract
The association among life events, personality factors, and anxiety disorders in children and adolescents was assessed in 28 children with obsessive-compulsive disorder (OCD), 28 children with other anxiety disorders (AD), and 24 normal controls using the Life Events Checklist (LEC) and the Junior Temperament and Character Inventory (JTCI). No significant differences were found among the groups for demographic and clinical characteristics. Children with OCD had significantly more total life events and more negative life events in the year before onset than normal controls, and they perceived the life events as having more impact. Scores for children with other AD fell between the other two groups for most of the life event parameters. The only specific life event that distinguished children with AD from normal controls was major illness or injury of a relative. High anxiety levels and older age--but not depression level--predicted a greater perceived impact of life events. Children with OCD and other AD both scored higher than normal controls on the harm avoidance parameter of the JTCI. Harm avoidance scores correlated positively and significantly with the reported occurrence of negative life events and their perceived impact. Thus, quantity, quality, and specificity of life events may be associated with AD in young people, especially OCD. This association may be related to the personality characteristic of harm avoidance.

Abstract
OBJECTIVE The purpose of this study was to assess changes in the temperament and character patterns in subjects with obsessive-compulsive disorder (OCD) following the treatment for obsessive/compulsive and accompanying depressive symptoms. METHOD Study subjects were 35 patients who met the DSM-IV criteria for OCD. All subjects were assessed with the Temperament and Character Inventory (TCI), the Yale-Brown Obsessive-Compulsive Scale, the Beck Depression Inventory, and the Beck Anxiety Inventory before and after a 4-month treatment. RESULTS Harm Avoidance (HA) scores in OCD subjects before treatment significantly decreased after treatment. However, the Self-Directedness scores, which were significantly lower than healthy comparison subjects before treatment, did not change. In addition, Reward Dependence scores in OCD subjects, which were not significantly different from healthy comparison subjects before treatment, significantly increased after treatment. CONCLUSION The TCI pattern of untreated OCD subjects (high HA and low Self-Directedness, relative to healthy comparison subjects) and the decrease of HA scores and no change in Self-Directedness scores following a successful treatment suggest that temperaments are more amenable to treatment than characters.

Abstract
BACKGROUND The numerous reports on research involving the clinical assessment of personality in axis I disorders highlight the importance of temperament features in the current approach to all mental disorders. However, the available instruments of personality assessment have many limits. Self-administered questionnaires depend on the patient's insight, and projective instruments (i.e. the Rorschach test) often lack objectivity. This study compared the results of personality assessment with the Temperament and Character Inventory (TCI) and the Rorschach test to verify their validity. PATIENTS AND METHODS TCI and Rorschach tests were administered to a wide sample of patients (n = 180) in a short period. The most common Rorschach siglatures were correlated with the TCI raw scores using the Pearson correlation test. RESULTS All TCI temperament dimensions and facets displayed at least two correlations with Rorschach siglatures. The description of each dimension and facet of the TCI obtained with the interpretation of Rorschach siglatures was consistent with its original meaning. CONCLUSIONS The TCI and Rorschach tests adequately validated each other. In the future, the administration and integration of these tests will overcome the biases of both. Further, the theoretical bases of the TCI could facilitate the study of psychological functions, whereas the psychodynamic bases of the Rorschach test provide an in-depth insight into temperament traits.

Abstract
A distinctive personality type, characterized by introversion, inflexibility, and low novelty seeking, has been suggested to be associated with Parkinson's disease. To test the hypothesis that Parkinson's disease is associated with a specific dopamine-related personality type, the personality structures of 61 unmedicated Parkinson's disease patients and 45 healthy controls were examined. Additionally, in 47 Parkinson's disease patients, the dopaminergic function in the brain was directly measured with 6-[(18)F]fluoro-l-dopa ((18)F-dopa) positron emission tomography (PET) with MRI coregistration. The novelty-seeking personality score, supposedly associated with the parkinsonian personality, was slightly lower in the Parkinson's disease group compared with controls, but it did not have a significant relationship with (18)F-dopa uptake in any of the brain regions studied (r = -0.12 to 0.11, P > 0.15). The harm-avoidance personality score, associated with anxiety and depression, was clearly increased in patients with Parkinson's disease and it had a paradoxical, highly significant positive correlation with the (18)F-dopa uptake in the right caudate nucleus (r = 0.53, P = 0.04, Bonferroni corrected for 220 comparisons). Although the results of this study are not in disagreement with the concept of low-novelty-seeking personality type in Parkinson's disease, the personality type does not seem to be dopamine dependent. The correlation between the personality trait of harm avoidance and (18)F-dopa may reflect a specific feedback circuitry of neurotransmitters that is associated with negative emotionality in Parkinson's disease.

Abstract
Obsessive-compulsive disorder (OCD) is a brain disorder with recognizable periods of onset, course, familial occurrence, epidemiology, phenomenology, and treatment response. Several manifestations of pathophysiology are beginning to be defined, although they may represent intermediate pathophysiology rather than primary etiology. Positron emission tomography studies have consistently identified hypermetabolism in the orbitofrontal cortex, caudate nucleus, and, sometimes, anterior cingulate cortex. Neuropsychologic testing frequently identifies abnormalities in visuospatial function. Abnormal levels of cerebrospinal fluid neurotransmitters and neuromodulators are identifiable in untreated patients with OCD and return toward normal levels after effective treatment. The most consistent pathophysiologic finding in OCD points toward an abnormality in serotonin neurotransmission. Therapeutic response to selective serotonin reuptake inhibitors and the absence of improvement with norepinephrine reuptake inhibitors and dopamine antagonists argue strongly for a role of serotonin in the pathophysiology and treatment of OCD. Despite this clear indication from treatment trials, probes and manipulations of the serotonin system and its specific receptors have not provided a useful understanding of specific abnormalities. Clomipramine or potent selective serotonin reuptake inhibitors are the pharmacotherapy of choice for OCD, with a more limited role reserved for monoamine oxidase inhibitors. If one selective serotonin reuptake inhibitor is ineffective, others may be beneficial, in addition to the different proserotonergic and nonserotonergic augmentation strategies that could be useful in treatment of resistant OCD patients. Nondrug therapies are also important in OCD: behavioral therapy is frequently helpful and neurosurgery is sometimes helpful when other treatments fail.
