A systematic review of misdiagnosis in those with obsessive-compulsive disorder

Comparison of retrospective and prospective memory in subtypes of obsessive-compulsive disorder

Retrospective and prospective memory deficits play a role in maintaining and perpetuating the symptoms of obsessive-compulsive disorder (OCD), but less is known about these deficits in different subtypes of OCD. The aim of the present study was to evaluate the retrospective and prospective memory in patients suffering from cleaning, checking, symmetry, and religious obsessions. In a comparative causal method, 60 participants aged 28 to 55, in 2023, were selected by convenience sampling and placed in five groups of individuals with cleaning, checking, symmetry, religious obsessions, and a healthy group. Participants completed self-report questionnaires and neurocognitive tools. Results showed that defects in retrospective memory were significant in all types of obsessions (p<0.05) except religious obsessions. Also, this defect was more severe in checking obsession disorder compared to other types of OCD. Also, the finding indicated that the defect in prospective memory was significant only in checking obsession disorder (p<0.05). Retrospective and prospective memory impairments and their relationship with deficits in executive functions can be different depending on the type of OCD. Based on the findings, impairment of executive function indirectly by impacting the impairment of other cognitive mechanisms diminishes confidence in retrospective and prospective memory which leads to compulsive behaviors in individuals with contamination and checking obsessions. Also, the impairment of retrospective memory in symmetry obsessions might have a relationship with information encoding, which in turn leads to difficulty recalling information from memory.

Obsessive-compulsive disorder among individuals of Hispanic and Latin American ancestry: Cultural considerations for assessment and psychotherapy

Research specific to obsessive-compulsive disorder (OCD) among individuals of Hispanic and Latin American (H/L) ancestry is limited, as are culturally relevant assessment and treatment recommendations. This article discusses the implications of underrepresentation of H/L populations in OCD research and emphasizes the need to consider issues related to assessment, treatment, and structural barriers that hinder delivery of culturally appropriate first-line psychotherapy. Recommendations for assessment and treatment are provided to aid clinicians in distinguishing culturally normative thoughts and behaviors from OCD, as well as to inform the implementation of psychotherapeutic interventions with cultural humility. This manuscript offers recommendations for future research to tackle health equity concerns with respect to assessment and treatment and structural factors limiting access to culturally appropriate psychotherapy. Wide-scale efforts are needed to comprehensively understand how H/L cultures intersect with various OCD presentations and to further disseminate treatments to populations that have historically lacked access to mental health care.

The Role of Alpha Oscillations among the Main Neuropsychiatric Disorders in the Adult and Developing Human Brain: Evidence from the Last 10 Years of Research

Alpha oscillations (7-13 Hz) are the dominant rhythm in both the resting and active brain. Accordingly, translational research has provided evidence for the involvement of aberrant alpha activity in the onset of symptomatological features underlying syndromes such as autism, schizophrenia, major depression, and Attention Deficit and Hyperactivity Disorder (ADHD). However, findings on the matter are difficult to reconcile due to the variety of paradigms, analyses, and clinical phenotypes at play, not to mention recent technical and methodological advances in this domain. Herein, we seek to address this issue by reviewing the literature gathered on this topic over the last ten years. For each neuropsychiatric disorder, a dedicated section will be provided, containing a concise account of the current models proposing characteristic alterations of alpha rhythms as a core mechanism to trigger the associated symptomatology, as well as a summary of the most relevant studies and scientific contributions issued throughout the last decade. We conclude with some advice and recommendations that might improve future inquiries within this field.

Sense of happiness and other aspects of quality of life in patients with obsessive-compulsive disorder

INTRODUCTION

Quality of life (QoL) is the intellectual and emotional wellbeing of an individual, which is determined by many factors. The most measurable are the sense of happiness, occupational satisfaction, quality of interpersonal relationships and sex life. Obsessive-compulsive disorder (OCD) is a chronic mental disorder diagnosed by the presence of obsessions and compulsions that disrupt normal psychosocial functioning. Despite early onset, treatment is delayed (OCD-DTI) and unsatisfactory.

OBJECTIVES

The primary objective of this study is to assess selected correlates of the sense of happiness among patients with OCD. The secondary objective is to compare the sense of happiness with healthy people.

METHODS

Seventyfive OCD patients and equal number of healthy subjects were compared using a Polish adaptation of the Oxford Happiness Questionnaire (OHQ-23).

RESULTS

We found a significant negative correlation between sense of happiness and the severity of OCD (r = -0.479), the number of obsessive-compulsive personality traits (r = -0.323), the number of other comorbid mental disorders (r = -0.272), the level of aggression (r = -0.448), impulsivity (r = -0.301), depressiveness (r = -0.357), and the sexual dysfunctions (r = -0.279). The latter were much more common in individuals with OCD compared to healthy subjects (66.67 vs. 12%). The level of loneliness was over two times higher in the study group compared to controls (27 vs. 12%). The mean delay in treatment onset was 13 years. Conclusions. Assessment of aspects of QoL should be an integral part of the diagnostic and therapeutic process in OCD.
