How Obsessive-Compulsive Symptoms Correlate with other Symptoms and Quality of Life in Schizophrenia? A Cross-Sectional Study

Background

Early psychiatrists inferred that obsessive-compulsive symptoms (OCS) represent a defense against psychosis and prevent the progression of schizophrenia. However, recent clinical research has yielded inconsistent results across studies regarding the link between OCS and the symptom domains of schizophrenia and the influence OCS have on a patient's functioning and quality of life (QOL).This study aimed to determine whether OCS has any association with the symptom severity, functioning, and QOL of schizophrenia patients.

Methods

This cross-sectional study done in a tertiary care hospital consecutively recruited 85 outpatients of schizophrenia in clinical remission over one year. Positive and Negative Syndrome Scale (PANSS), Yale-Brown Obsessive Compulsive Scale (Y-BOCS), WHO Quality of Life Brief Version (WHO QOL-BREF), and Global Assessment of Functioning (GAF) scales were applied.

Results

Eighteen patients (21.2%) had OCS (Y-BOCS score of ≥8). Patients with OCS had higher PANSS scores (mean±SD of total score 77.16± 16.4, P < 0.001), suggestive of more severe psychosis, poor functioning overall (mean GAF score 37.35 ± 15.62, P < 0.001), and poor QOL in the psychological domain (P < 0.001). In addition, significant associations were present between the Y-BOCS score and the PANSS (r = 0.65), GAF (r = -0.61), and WHO QOL BREF scores in the physical (r = -0.39), and psychological domains (r = -0.41) (P < 0.001 on all of the above).

Conclusions

Patients with OCS have more severe symptoms and a lower QOL. A significant association exists between the intensity of OCS and schizophrenia symptoms, global functioning, and QOL.

Blasphemous thoughts in obsessive-compulsive disorder: A case series

Obsessive-compulsive disorders (OCDs) are one of the top 10 contributors of debilitating medical illnesses and are the fourth most common psychiatric disorder. Blasphemous thoughts, also known as scrupulosity, as an obsessional theme has piqued curiosities long before it was considered a neurosis. Such obsessions may or may not have an accompanying compulsion and comprise 5% of the patients of OCD. The case series is of three patients suffering from repetitive, intrusive, ego-dystonic, and distressing blasphemous thoughts, which are extremely distressing to them, rendering them unable to perform any other activity. The symptoms also indicate the presence of comorbid depressive and anxiety disorders, developing secondary to the blasphemous thoughts. Inadequate knowledge in this subtype of OCD mandates the need for more studying and research, especially with new texts suggesting the implementation of faith-assisted psychotherapy in addition to the conventional psychotherapy and pharmacotherapy.

Concordance of assessment of insight by different measures in obsessive-compulsive disorder: An outpatient-based study from India

AIMS

This study aimed to examine the (a) prevalence of various levels of insight among patients with obsessive-compulsive disorder (OCD) and (b) correlation of insight specifier (Diagnostic and Statistical Manual [DSM]-5) and other established measures of insight in OCD.

METHODS

One hundred and twenty-five outpatients with a diagnosis of OCD were assessed by Brown Assessment of Beliefs Scale (BABS) and DSM-IV's insight specifier. The insight specifier of DSM-5 was determined by item one ("conviction") of BABS. Dimensional Yale-Brown Obsessive-Compulsive Severity Scale was used to assess the frequency and severity of dimensional obsessive-compulsive (OC) symptoms.

RESULTS

The mean age of the participants was 31.2 (±11) years. Seventy-seven (61.6%) of the participants were men. There was a high correlation (r = 0.73) between the insight specifiers of DSM-5 and DSM-IV. Insight categories of DSM-5 had modest correlations with BABS total score and BABS-based insight categories. Significant associations were observed between the level of insight and comorbid psychotic illness, hoarding and symmetry dimensions of OC symptoms, severity of depressive, and OC symptoms. The first two associations were consistent across group comparisons (insight-groups based on DSM-IV and BABS) and correlation (with total BABS score).

CONCLUSIONS

Majority of the patients with OCD have good insight and application of different tools influence the assessment of insight in OCD. The DSM-5 insight specifier has strong and significant correlation with the DSM-IV's insight classification and categorization of insight by BABS.

Robotic Guided Bilateral Anterior Cingulate Radiofrequency Ablation for Obsessive-Compulsive Disorder

Background

Bilateral anterior cingulotomy (BAC) constitutes the most commonly performed procedure for treatment of refractory OCD. Evolution of stereotactic procedures has rekindled the interest in the effective management of refractory psychiatric disorders, especially OCD with utmost safety and excellent outcomes.

Objective

The aim of this study was to demonstrate the technique of performing BAC under robotic guidance using radiofrequency ablation with an operative video.

Procedure

A 23-year-old gentleman diagnosed with symptoms of OCD for a duration of 8 years and was refractory to conventional therapy. The trajectories for BAC were planned on the robotic platform (ROSA, Zimmer-Biomet, Warsaw, Indiana, USA). The target point was selected on the anterior cingulate, approximately 2 cms posterior to the anterior most point of the frontal horn, 2-3 mm above the corpus callosum and 7 mm lateral to the midline. Pre coronal (1 cm anterior and 3 cms lateral to midline) holes of 2.5 mm diameter were made using pneumatic handheld drill. Radiofrequency (RF) thermocoagulation of the anterior cingulum was performed using an RF probe of 2.2 mm diameter and 4 mm uninsulated tip under robotic guidance after confirming the position with intraoperative O-arm imaging bilaterally.

Results

The surgery was uneventful and the patient had a significant improvement following surgery, with the Yale Brown Obsessive Compulsive Scale of 18 at 1 year follow-up compared to the preoperative score of 36.

Conclusion

Robotic-guided BAC is a safe and effective technique for the treatment of drug-refractory OCD. Intraoperative O arm CT augments the precision of the lesions created.

Cross-sectional study of internalised stigma and medication adherence in patients with obsessive compulsive disorder

Background

Patients suffering from psychiatric disorders tend to stigmatise themselves which had been linked to poor adherence to treatment.

Aims

The aim of the present study was to study internalised stigma and medication adherence and to assess the relationship between them in patients with obsessive compulsive disorder (OCD).

Methods

A cross-sectional study was conducted on 112 patients diagnosed with OCD who were attending the Out-patient's department at Department of Psychiatry of a tertiary care hospital in North India. Internalised stigma and current medication adherence were assessed with Internalized Stigma of Mental Illness Scale (ISMI) and Medication Adherence Rating Scale, respectively. Yale-Brown Obsessive Compulsive Scale was used to assess the current severity of OCD symptoms. Sociodemographic and clinical details were also obtained from the patients by using a semistructured sociodemographic proforma.

Results

Most of the patients reported moderate level of internalised stigma with a mean ISMI score of 77.98 (10.82). Most of the patients were compliant while 41.96% reported poor medication adherence. Internalised stigma was negatively correlated with the current medication adherence. Current severity of OCD symptoms also showed a significant positive correlation with internalised stigma and a significant negative correlation with medication adherence.

Conclusion

High levels of internalised stigma were associated with lower adherence to treatment which suggests that internalised stigma may be a very important factor influencing medication adherence in patients with OCD.

Clinical profile of obsessive-compulsive disorder in children and adolescents: A multicentric study from India

CONTEXT

Data from the Western countries suggest that obsessive-compulsive disorder (OCD) in children and adolescents is associated with male preponderance, comorbid neurodevelopmental disorders, and high family loading. However, data are limited from the developing countries with respect to the demographic and clinical characteristics of OCD in children and adolescents.

AIMS

To study the demographic and clinical characteristics of children and adolescents (age ≤18 years) with OCD.

SETTING AND DESIGN

This was a cross-sectional study, conducted in outpatient treatment setting, across six centers in India.

MATERIALS AND METHODS

Participants were assessed using a semi-structured pro forma for sociodemographic information, clinical characteristics, the Children's Yale Brown Obsessive Compulsive Scale (CYBOCS), Structured Clinical Interview for Diagnostic and Statistical Manual, 5^th Edition Research Version, Children's Depression Rating Scale, and Family Interview for Genetic Studies.

RESULTS

The sample was largely male with a moderate illness severity. Nearly 75% of the sample had illness onset before the age of 14 years. Aggressive, contamination-related obsessions and washing, checking, and repeating compulsions were the most common symptoms. CYBOCS assessment revealed that >2/3^rd of children and adolescents endorsed avoidance, pathological doubting, overvalued sense of responsibility, pervasive slowness, and indecisiveness. Family history and comorbidity rates were low. OC-related disorders were present in about 10% of the sample.

CONCLUSIONS

This study suggests that the clinical characteristics of OCD in children and adolescents in developing countries differ on certain aspects as reported from developed countries.

Early intervention for obsessive compulsive disorder: An expert consensus statement

Obsessive-compulsive disorder (OCD) is common, emerges early in life and tends to run a chronic, impairing course. Despite the availability of effective treatments, the duration of untreated illness (DUI) is high (up to around 10 years in adults) and is associated with considerable suffering for the individual and their families. This consensus statement represents the views of an international group of expert clinicians, including child and adult psychiatrists, psychologists and neuroscientists, working both in high and low and middle income countries, as well as those with the experience of living with OCD. The statement draws together evidence from epidemiological, clinical, health economic and brain imaging studies documenting the negative impact associated with treatment delay on clinical outcomes, and supporting the importance of early clinical intervention. It draws parallels between OCD and other disorders for which early intervention is recognized as beneficial, such as psychotic disorders and impulsive-compulsive disorders associated with problematic usage of the Internet, for which early intervention may prevent the development of later addictive disorders. It also generates new heuristics for exploring the brain-based mechanisms moderating the 'toxic' effect of an extended DUI in OCD. The statement concludes that there is a global unmet need for early intervention services for OC related disorders to reduce the unnecessary suffering and costly disability associated with under-treatment. New clinical staging models for OCD that may be used to facilitate primary, secondary and tertiary prevention within this context are proposed.

Neurocognitive deficits in obsessive-compulsive disorder: A selective review

Obsessive-compulsive disorder (OCD) is a debilitating mental illness characterized by an early onset and chronic course. Evidence from several lines of research suggests significant neuropsychological deficits in patients with OCD; executive dysfunction and nonverbal memory deficits have been reported consistently in OCD. These deficits persist despite controlling potential confounders such as comorbidity, severity of illness, and medications. Neuropsychological impairments are independent of illness severity, thus suggesting that the neuropsychological deficits are trait markers of the disease. In addition, these deficits are seen in first-degree relatives of individuals with OCD. These reports suggest that neuropsychological deficits are potential endophenotype markers in OCD. Neuropsychological studies in pediatric OCD are limited; they show impairments of small effect size across multiple domains but with doubtful clinical significance. Preliminary evidence shows that different symptom dimensions of OCD may have unique neuropsychological deficits suggestive of discrete but overlapping neuroanatomical regions for individual symptom dimensions. Overall, neuropsychological deficits further support the role of frontostriatal circuits in the neurobiology of OCD. In addition, emerging literature also suggests the important role of other areas, in particular parietal cortex. Preliminary evidence suggests the possible role of neuropsychological deficits to be markers of treatment response but needs to be examined in future. Longitudinal studies with examination of patients at different time points and examination of their potential utility as predictors of treatment response are needed in future.

Relationships between neuropsychological variables and factor-analysed symptom dimensions in obsessive compulsive disorder

Despite mounting evidence for the distinctiveness of symptom dimensions in obsessive-compulsive disorder, neuropsychological studies have been few, focused on small samples, and relying on classification of participants based on mutually exclusive symptom categories, resulting in lack of concordance across neuropsychological and imaging studies. Neuropsychological assessment was undertaken with 150 individuals with DSM IV OCD, and neuropsychological variables were analysed in relation to symptom dimension scores derived from factor analysis. Five dimensions were derived from principal components analysis with varimax rotation - contamination/washing, doubts/checking, symmetry/ordering, forbidden thoughts, and hoarding. After controlling for severity of depression and OCD, antipsychotic and benzodiazepine use, and all other symptom dimensions, washing was associated with poorer attention/working memory, visuo-spatial construction and better planning time; checking was related to poorer alternation learning; symmetry linked with poorer verbal fluency; forbidden thoughts with better visuospatial scanning and working memory; hoarding with poorer immediate verbal recall and better visuospatial working memory. The neuropsychological associations are explained in the context of existing neuroimaging evidence, and the clinical picture of each symptom dimension. The use of factor-analysed symptom dimensions and a large sample of individuals with OCD are strengths of the study.

The prevalence of psychopathology in siblings of children with mental health problems: a 20-year systematic review

While the importance of looking at the entire family system in the context of child and adolescent mental health is well recognised, siblings of children with mental health problems (MHPs) are often overlooked. The existing literature on the mental health of these siblings needs to be reviewed. A systematic search located publications from 1990 to 2011 in four electronic databases. Thirty-nine relevant studies reported data on the prevalence of psychopathology in siblings of target children with MHPs. Siblings of target children had higher rates of at least one type of psychopathology than comparison children. Risk of psychopathology varied across the type of MHP in the target child. Other covariates included sibling age and gender and parental psychopathology. Significant variations and limitations in methodology were found in the existing literature. Methodological guidelines for future studies are outlined. Implications for clinicians, parents, and for future research are discussed.

Pathogenetic and therapeutic perspectives on neurocognitive models in psychiatry: A synthesis of behavioral, brain imaging, and biological studies

Neurocognitive assessments are useful to determine the locus of insult as well as functional capacities of patients on treatment. In psychiatry, neurocognitive assessment is useful in the identification of brain lesions, evaluation of cognitive deterioration over time, and advancement of theories regarding the neuroanatomical localization of symptoms. Neurocognitive models provide a bridging link between brain pathology and phenomenology. They provide a useful framework to understand the pathogenesis of psychiatric disorders, bringing together isolated findings in behavioral, neuroimaging, and other neurobiological studies. This review will discuss neurocognitive model of three disorders - schizophrenia, bipolar disorder, and obsessive compulsive disorder - by incorporating findings from neurocognitive, neuroimaging, and other biological studies.

Antidepressant-induced mania in obsessive compulsive disorder

Serotonin-reuptake inhibitors have come forth to become the mainstay of treatment in obsessive compulsive disorder (OCD), predominantly as a result of evidence from clinical psychopharmacological response studies. Comorbid psychiatric disorders frequent OCD patients, most often depression. Although selective serotonin reuptake inhibitors are effective in the treatment of both OCD and depressive disorder, all antidepressants are associated with treatment-emergent affective switch. We present a 48-year-old patient with OCD, on antidepressants, initially for OCD and later for depression as well. She switched to mania after 20 years of treatment, which responded to olanzapine and divalproex sodium.
