The COVID-19 pandemic and obsessive-compulsive disorder in young people: Systematic review

BACKGROUND

The COVID-19 pandemic has impacted the world since the first cases were reported in China in January 2020. The secondary mental health impacts of the pandemic are thought to be significant. Obsessive-compulsive disorder is a condition defined by recurrent obsessions and compulsions. It has been hypothesised that the focus on hygiene and contamination during the pandemic could exacerbate obsessive-compulsive symptoms in young people.

METHOD

A systematic literature review was conducted. Papers were sought looking at the effect of the pandemic on obsessive-compulsive disorder in young people.

RESULTS

Six published cross-sectional and longitudinal studies were identified, of which four studies investigated clinic samples with a diagnosis of obsessive-compulsive disorder and two looked at community adolescent populations. Five out of the six studies found that obsessive-compulsive symptoms were exacerbated during the COVID-19 pandemic.

CONCLUSION

The COVID-19 pandemic appears to be associated with a worsening of obsessive-compulsive symptoms in young people. Being in treatment seems to have a protective effect. Maintaining mental health services during a pandemic is vital. It is important to be aware of the implications of pandemic on obsessive-compulsive symptoms in young people in order to allow them to access appropriate treatments. More research is needed in this area.

Cross-Disorder Genetic Analysis of Tic Disorders, Obsessive-Compulsive, and Hoarding Symptoms

Hoarding, obsessive-compulsive disorder (OCD), and Tourette's disorder (TD) are psychiatric disorders that share symptom overlap, which might partly be the result of shared genetic variation. Population-based twin studies have found significant genetic correlations between hoarding and OCD symptoms, with genetic correlations varying between 0.1 and 0.45. For tic disorders, studies examining these correlations are lacking. Other lines of research, including clinical samples and GWAS or CNV data to explore genetic relationships between tic disorders and OCD, have only found very modest if any shared genetic variation. Our aim was to extend current knowledge on the genetic structure underlying hoarding, OC symptoms (OCS), and lifetime tic symptoms and, in a trivariate analysis, assess the degree of common and unique genetic factors contributing to the etiology of these disorders. Data have been gathered from participants in the Netherlands Twin Register comprising a total of 5293 individuals from a sample of adult monozygotic (n = 2460) and dizygotic (n = 2833) twin pairs (mean age 33.61 years). The data on Hoarding, OCS, and tic symptoms were simultaneously analyzed in Mplus. A liability threshold model was fitted to the twin data, analyzing heritability of phenotypes and of their comorbidity. Following the criteria for a probable clinical diagnosis in all phenotypes, 6.8% of participants had a diagnosis of probable hoarding disorder (HD), 6.3% of OCS, and 12.8% of any probable lifetime tic disorder. Genetic factors explained 50.4, 70.1, and 61.1% of the phenotypic covariance between hoarding-OCS, hoarding-tics, and OCS-tics, respectively. Substantial genetic correlations were observed between hoarding and OCS (0.41), hoarding and tics (0.35), and between OCS and tics (0.37). These results support the contribution of genetic factors in the development of these disorders and their comorbidity. Furthermore, tics were mostly influenced by specific environmental factors unshared with OCS and HD.

Stressful Life Events and the Clinical Expression of Obsessive-Compulsive Disorder (OCD): An Exploratory Study

BACKGROUND

In obsessive-compulsive disorder (OCD), symptom content and severity appear to fluctuate over the course of the life cycle in accordance with stressful life events. The objective of this paper was to compare OCD patients with and without reported stressful life events (SLEs) in terms of the sociodemographics of patients and the clinical characteristics of OCD.

METHODS

This was a cross-sectional study involving 1001 patients with OCD. Data concerning SLEs were collected via the Yale OCD Natural History Questionnaire, while for OCD symptoms, the Dimensional Yale-Brown Obsessive-Compulsive Scale was used.

RESULTS

Of the 1001 OCD patients, 605 (60.5%) reported experiencing at least one SLE in their lifetime. Self-declared nonwhite skin color (odds ratio (OR) = 1.51), the presence of a sensory phenomenon (OR = 1.47), and comorbidity with post-traumatic stress disorder (PTSD) (OR = 2.38) were some of the logistic regression variables related to the reported SLEs with relevant statistical significance and risk (i.e., OR) values.

CONCLUSIONS

Our results indicate that SLEs may make Brazilian OCD patients vulnerable to the onset or exacerbation of obsessive-compulsive symptoms. The positive association of the occurrence of SLEs and sensory phenomena in this population could corroborate that environmental influences impact the neurobiology associated with OCD, and likely with other psychiatric disorders as well.

Hand Washing: When Ritual Behavior Protects! Obsessive-Compulsive Symptoms in Young People during the COVID-19 Pandemic: A Narrative Review

The Coronavirus Disease 2019 (COVID-19) pandemic had a profound impact on the lifestyles and mental health of young people. It has been hypothesized that the focus on hygiene and the fear of contamination/infection during the pandemic may have exacerbated obsessive–compulsive (OC) symptoms in this population. OC symptoms are widespread in the general population, with varying degrees of intensity. At their most extreme, they manifest in obsessive–compulsive disorder (OCD), which is characterized by obsessive thoughts and compulsive behaviors. The present narrative review aimed at evaluating the relationship between the COVID-19 pandemic and OCD and OC symptoms in young people, especially children and adolescents with and without OCD, focusing on vulnerability and risk factors and the impact of lockdown measures. Of the six studies identified, four examined clinical samples diagnosed with OCD and two looked at community-based adolescent samples. Five of the six studies found that OC symptoms increased during the pandemic. Additionally, vulnerability to anxiety may constitute a risk condition and the lockdown measures and personal stressful life events can constitute potential triggers of OC symptoms, while ongoing treatment for OCD had a protective effect. The results suggest that, during the COVID-19 pandemic, obsessive and compulsive behavior (e.g., hand washing) in young people at the greatest risk should be monitored, and the intervention of mental health services should be maintained. More research is needed in this area.

Obsessive compulsive symptoms are related to lower quality of life in patients with Schizophrenia

BACKGROUND

The aim of this study is to investigate the effects of obsessive-compulsive symptoms (OCS) on quality of life (QoL) and to identify the OCS with a particular effect on QoL, and whether there are any such symptoms for patients with schizophrenia.

METHODS

We studied three groups of patients with schizophrenia. One group of patients (n = 45) without OCS or obsessive-compulsive disorder (OCD), one group with OCS, not fulfilling the diagnostic criteria for OCD (n = 31), and one group with OCD as a comorbid condition (n = 24). Severity of clinical symptoms was evaluated with the Positive and Negative Symptom Scale and OCS was examined using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) Symptom Checklist. We also administered the Y-BOCS. The patients' QoL was assessed using the Quality of Life Scale (QLS).

RESULTS

QLS interpersonal relationships subscale scores of those with OCS were lower than those without OCS. There was no difference among OCS, non-OCS, and OCD groups in terms of QoL. There was no relationship between QLS scores and symmetry, contamination and causing harm obsessions, but those with cleaning and repeating compulsions had lower QoL.

CONCLUSIONS

Questioning of comorbid OCS and treatment with specific medication in schizophrenia patients may increase QoL.

Obsessive-compulsive symptoms in schizophrenia: prevalence and associated factors in a Nigerian population

OBJECTIVES

The objectives of this study were to determine the prevalence of obsessive-compulsive symptoms (OCS) among subjects with schizophrenia and also to determine their associated factors.

METHODS

A cross-sectional study involving 232 patients with schizophrenia were recruited from a teaching hospital in Nigeria. Socio-demographic questionnaire, Obsessive-Compulsive Inventory, Positive and Negative Syndrome Scale and Suicidality module of the MINI International Neuropsychiatric Inventory were administered.

RESULTS

The prevalence of OCS was 54.3% among patients with schizophrenia, and washing symptom was the most common (51.7%). Patients with schizophrenia that had OCS had more severe psychopathologies and higher levels of suicidality. OCS among patients with schizophrenia were also associated with the use of second-generation antipsychotic medications.

CONCLUSIONS

OCS are common in schizophrenia. Hence, there is a need for routine screening of patients with schizophrenia for OCS and then, manage them appropriately.

Changes in Sensory Phenomena, Tics, Obsessive-Compulsive Symptoms, and Global Functioning of Tourette Syndrome: A Follow-Up After Four Years

Sensory phenomena and related features of Tourette syndrome are related to poorer quality of life. Therefore, sensory phenomena might also have a negative impact on global functioning. However, the influence of sensory phenomena, tics, and obsessive-compulsive symptoms (OCS) on global functioning after several years of usual treatment has not been investigated. Twenty out of 45 Japanese patients with Tourette syndrome who had previously undergone an evaluation of these clinical features were assessed again after an average of four years. We conducted a panel of assessments for premonitory urges, broader sensory phenomena, tic severity, OCS, and global functioning. Based on Pearson's correlation coefficient, current global functioning was significantly negatively correlated with previous tics and marginally negatively correlated with previous broader sensory phenomena. Current global functioning was marginally correlated with change in tics. Change in global functioning was significantly correlated with change in OCS and marginally correlated with change in premonitory urges. Due to the small sample size, it was not possible to use a multiple regression analysis to conclude that sensory phenomena, tics, and OCS predict global functioning in adolescents and adults with TS. However, it was suggested that further investigation of this relationship would be meaningful.

Obsessive-compulsive symptoms in patient with schizophrenia: The influence of disorganized symptoms, duration of schizophrenia, and drug resistance

BACKGROUND

Schizophrenia is a chronic mental disorder with a many-faced clinical presentation. Obsessive-compulsive symptoms are often part of it. The characteristics of the clinical picture and the course of schizophrenia are factors related to both the resistance and the manifestation of obsessive-compulsive symptoms. Our study aims to establish the relationship between the peculiarities of the schizophrenia process and the influence of resistance on the expression of obsessive-compulsive symptoms.

METHODS

A study was conducted on 105 patients with schizophrenia. Of them, 39 are men and 66 are women. The evaluation of the effectiveness of the treatment showed that 45 were resistant to the applied therapy, while the remaining 60 responded. Clinical assessment of patients was performed using the Positive and Negative Syndrome Scale (PANSS) and Brief Psychiatric Rating Scale (BPRS). Assessment of obsessive-compulsive symptoms (OCS) was conducted with the Dimensional obsessive-compulsive symptoms scale (DOCS).

RESULTS

In 34% of all patients, we found clinically expressed obsessive-compulsive symptoms. In 40% of the patients with resistance, we found clinically expressed obsessive-compulsive symptoms, which are within the range of moderately expressed. In 30% of the patients in clinical remission, we found obsessive-compulsive symptoms, but mildly expressed. We found a statistically significant relationship between the severity of OCS and the disorganized symptoms and the duration of the schizophrenia process. No differences were found in the expression of OCS in patients of both sexes.

CONCLUSION

We registered both an increased frequency and an increased expression of obsessive-compulsive symptoms in patients with resistant schizophrenia. These symptoms were positively associated with disorganized symptoms and duration of schizophrenia. No relationship was established with the positive, negative symptoms, as well as with the gender distribution.

Aripiprazole-induced obsessive-compulsive symptoms

Aripiprazole is a novel antipsychotic with a unique pharmacological profile as a dopamine partial agonist. It is indicated for treatment of schizophrenia and bipolar disorder. This new antipsychotic has low rate of extrapyramidal side effects, metabolic changes and no significant adverse effect on serum prolactin concentration. In addition,it is not associated with significant weight gain like other atypical antipsychotics. As a reason, when other antipsychotics cause these adverse events, it's not uncommon to switch to Aripiprazole. Obsessive compulsive symptoms have been untoward sequel of a few second-generation antipsychotics. Among the second generation antipsychotics Clozapine, Olanzapine, and Risperidone are the most prominent agents associated with these sequelae, according to case reports. More recently, a handful of case reports indicated development of Obsessive-compulsive symptoms with Aripiprazole. We report a case that exhibited similar unexpected adverse effects after administration of Aripiprazole. Keywords: Aripiprazole, Second generation antipsychotics, Obsessive-compulsive symptoms (OCS).

The Relevance of Mindfulness and Thought Suppression to Scrupulosity

The purpose of this study was to examine the relevance of the mindfulness and thought suppression to scrupulosity, or religious obsessions. It was hypothesized that scrupulosity would be negatively associated trait mindfulness and positively associated with thought suppression. It was also hypothesized that thought suppression and mindfulness would mediate the association between scrupulosity and symptoms of obsessive-compulsive disorder (OCD). A survey-based study was conducted to test these hypotheses in a large, nonreferred sample. In particular, undergraduate university students completed a number of self-report measures, including the Pennsylvania Inventory of Scrupulosity (PIOS), the Five Facet Mindfulness Questionnaire- Short Form (FFMQ-SF), and the White Bear Suppression Inventory (WBSI) in exchange for extra credit. As anticipated, mindfulness was significantly associated with scrupulosity, with a particularly strong and negative association found between the PIOS and the nonjudging subscale of the FFMQ-SF. Further, thought suppression was found to be significantly and positively associated scores on the PIOS, with correlations in the moderate to strong range. Further, as anticipated, mindfulness and thought suppression mediated the relation between scrupulosity and thought suppression. Overall, the findings provide insight into the cognitive processes related to persistent and disruptive levels of scrupulosity.

Domperidone Use as a Galactagogue and Infanticide Ideation: A Case Report

Objectives: Domperidone is an antiemetic that is commonly used as an off-label prescription to induce lactation. Neuropsychiatric adverse effects of domperidone such as akathisia and depression are previously described. It has never been reported to be associated with infanticide ideation. The aim of this article is to discuss the occurrence of infanticide ideation following domperidone usage in an adoptive mother and the potential mechanisms by which these may occur. Methods: With Institutional Review Board approval, we herein report a nulliparous adoptive mother who developed infanticide ideation after 3 months of exposure to domperidone. The infanticide ideation was intrusive, recurrent, ego-dystonic, causing significant depressive symptoms and affecting the patient's functions. Physical examination and relevant biological investigations were unremarkable. Results: The patient is treated as domperidone-induced obsessional thought with adjustment disorder. The domperidone was stopped immediately. Serotonin and norepinephrine reuptake inhibitors was started. The infanticide ideation gradually resolved and patient achieved complete remission after 10 months of treatment. Conclusion: The infanticide ideation following consumption of domperidone is a potential neuropsychiatric adverse event that warrants further examination into the safety of domperidone as an "off-labeled" galactagogue. Comprehensive psychological assessment of mother who wishes to use domperidone as galactagogue is recommended.

Unraveling the Boundaries, Overlaps, and Connections between Schizophrenia and Obsessive-Compulsive Disorder (OCD)

Schizophrenia (SCZ) and obsessive-compulsive disorder (OCD) typically have distinct diagnostic criteria and treatment approaches. SCZ is characterized by delusions, hallucinations, disorganized speech, and cognitive impairments, while OCD involves persistent, intrusive thoughts (obsessions) and repetitive behaviors (compulsions). The co-occurrence of these disorders increases clinical complexity and poses significant challenges for diagnosis and treatment. Epidemiological studies indicate a significant overlap, with prevalence rates of comorbid OCD in SCZ patients ranging from 12% to 25%, which is higher than in the general population. Etiological hypotheses suggest shared genetic, neurobiological, and environmental factors, with genetic studies identifying common loci and pathways, such as glutamatergic and dopaminergic systems. Neuroimaging studies reveal both overlapping and distinct neural abnormalities, indicating shared and unique neurobiological substrates. Environmental factors, like early life stressors and urbanicity, also contribute to the comorbidity. The overlapping clinical features of both disorders complicate diagnosis. Treatment approaches include combining SSRIs with antipsychotics and cognitive behavioral therapy (CBT). The complexity of SCZ and OCD comorbidity underscores the need for a dimensional, spectrum-based perspective on psychiatric disorders, alongside traditional categorical approaches, to improve diagnosis and treatment outcomes.

An Analysis of Drinking Motives in the Maintenance of Co-Occurring Obsessive-Compulsive Symptoms and Alcohol Misuse

Objective: Despite the commonly observed co-occurrence of obsessive-compulsive symptoms (OCS) and substance use in clinical populations, few researchers have examined potential mechanisms which contribute to this relationship. This study assessed the mediating role of drinking motives in the relationship between OCS, alcohol consumption, and its resulting health risks among U.S. adults. Methods: Adult participants (n = 1966; Mage = 47.72, SD = 17.91; 76.30% female; 86.10% non-Hispanic White) sourced from Research Match answered an online questionnaire containing measures related to substance use and anxiety-related symptoms. Results: As hypothesized, there was a significant positive indirect path between OCS and both alcohol consumption and risky alcohol use through coping motives. However, there were also small indirect effects of OCS through social motivations for consumption and conformity motivations for risky alcohol use. Conclusions: These results add evidence that coping motives play a role in OCS and alcohol misuse and highlights the need to also consider drinking motives related to social facilitation and conformity in those with co-occurring OCS and alcohol misuse.

Multidimensional Assessment of Orthorexia Nervosa: A Case-Control Study Comparing Eating Behavior, Adherence to the Mediterranean Diet, Body Mass Index, Psychological Symptoms, and Autonomic Arousal

Background: The research on orthorexia nervosa (ON) has thoroughly outlined the connection between it and various mental disorders, including obsessive-compulsive disorders and eating disorders, in addition to stress. However, research has not considered psychophysical stress and other measures of psychophysical health, such as adherence to the Mediterranean diet. Methods: This cross-sectional and case-control research involved 63 students from the University of Parma, aged between 18 and 49 years. The ORTO-15 questionnaire was utilized to categorize the entire sample into two groups: one without orthorexia (score > 35) and another with orthorexia (score < 35). All subjects were assessed with the Psychophysiological Stress Profile (PSP) and completed the Eating Disorder Inventory-3 (EDI-3) and the Symptom Checklist-90-Revised (SCL-90-R). In addition, they were interviewed using the PREDIMED questionnaire to assess adherence to the Mediterranean Diet, and their body mass index (BMI) was calculated. Results: Subjects with orthorexia represented 38.10% of the total sample and reported a higher BMI than controls, although the PREDIMED score did not show a difference in adherence to the Mediterranean diet. The EDI-3 highlighted emotional dysregulation and hypercontrol in students with orthorexia, and a dissociation between subjective and objective measures of stress emerged. Particularly, the psychophysiological parameters of skin conductance, heart rate, and heart rate variability showed greater reactivity to stressful stimuli, but no difference was noted in psychological symptoms. Conclusions: These findings confirmed the presence of alterations in eating behavior in people with orthorexia as well as a higher BMI. It was hypothesized that hypercontrol might favor the perception of psychological well-being at a subjective level, although inadequate management of stress emerged at an objective psychophysiological level. Further studies are needed to highlight the causality between ON, hypercontrol, diet, and psychophysical stress, given that students with orthorexia present a dysregulation of emotions associated with greater autonomic arousal.

Explaining Interaction of Guilt and Obsessive-Compulsive Symptoms in Not Just Right Experiences

Objective

"Not Just Right Experiences" (NJREs) are currently considered a characteristic of Obsessive-Compulsive Disorder (OCD). Significant associations have been found between NJREs and Obsessive-Compulsive (OC) symptoms in nonclinical and clinical populations. Literature support a significant relationship between NJREs, feelings of guilt and OC features. This study aims to clarify the role of the potential interplay between guilt and OC symptomatology in NJREs and verify if high levels of guilt will predict NJREs and OC symptoms and trait guilt levels will positively interact in their prediction of NJREs.

Method

One hundred and eighty-nine adults recruited from normal population were assessed with questionnaires of NJREs and OC symptoms and proneness to experience guilt.

Results

All the variables involved in the study (NJREs severity, guilt and OCI-R scores) were positively and significantly correlated and showed that guilt and OCI-R scores significantly and positively interact in the prediction of NJREs levels. Guilt predicted NJREs only when levels of OCI-R were high.

Conclusions

These results support the association between guilt sensitivity or OC symptoms and NJREs in clinical and nonclinical participants and that a disposition toward high levels of guilt and OC symptoms have a particular sensitivity to NJREs corroborating centrality of guilt in OC symptoms.

Predictors of psychotic experiences among adolescents with obsessive-compulsive symptoms: A data-driven machine learning approach

Aim

Prediction of future psychosis in individuals with obsessive and compulsive (OC) symptoms is crucial for treatment choice, but only a few predictors have been revealed. Although OC symptoms and psychotic experiences (PEs) are common in adolescence, no studies have revealed the predictors of subsequent PEs in adolescents with OC symptoms. We aimed to explore the predictors for subsequent PEs among adolescents with OC symptoms, using a data-driven machine-learning approach on an adolescent cohort.

Methods

We used data from a cohort study on the general population of adolescents in Tokyo (n = 3171 at age 10). Data were collected at age 10, 12, 14, and 16. We focused on a subgroup of participants who had OC symptoms at age 12. Participants who had PEs at age 10 were excluded. A machine learning method was utilized to explore over 600 potential predictors at baseline, distinguishing between those who had an onset of PEs after age 14 (n = 45) and those who never had PEs (n = 99).

Results

The predicting model demonstrated a good performance (test area under the curve = 0.80 ± 0.05). Other than known risk factors for PEs, novel predictors of subsequent PEs among adolescents with OC symptoms included: lack of interaction with people of different ages, desire to be like their father in the future, and nonworking of primary caregiver when they were 5 years old. Not sharing their belongings readily with other children was a strong predictor of having no PEs.

Conclusion

Close-knit family bonds and limited social connections outside the family predict the later PEs among adolescents with OC symptoms.
