Summary: Hoarding disorder (HD) is a mental disorder characterized by difficulty parting with possessions and impairing life functioning. Research shows that individuals with HD have poor sleep quality, higher levels of insomnia symptoms, and comorbid sleep disorders. Sleep may be a new target for treatment in improving outcomes for individuals with HD.

Summary: This study investigated the deterioration of symptoms of obsessive-compulsive and related disorders (OCRDs) during the COVID-19 pandemic, finding that factors such as being female, experiencing more COVID-19 related stressful events, and having higher compulsivity traits predicted worsened symptoms during the pandemic. Identifying a pre-pandemic profile of individuals most at risk of symptom deterioration may be valuable for future preventative initiatives related to COVID-19 or other communicable diseases. Future studies should follow up on these findings longitudinally.

Summary: Research has found a high frequency of hoarding symptoms in patients with ADHD, with inattention being a significant predictor of hoarding severity. Despite the potential impact on everyday functioning, individuals with ADHD do not typically disclose associated difficulties, highlighting the importance of routine assessment for HD in this population. Further research on HD in younger adults with ADHD is needed, as they differ in demographics from typical HD samples.

Summary: This study investigated the association between attention-deficit/hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD) in adult patients.

Summary: People reporting compulsive hoarding symptoms (CHS) have lower mindfulness skills, which can act as a protective buffer against stress. The quarantine during COVID-19 had a negative impact on daily habits and behaviors, potentially leading to increased attachment to objects such as hoarding tendencies. This preliminary investigation found a higher prevalence of CHS during quarantine, indicating a need for further research and monitoring of this pattern.

Summary: This study expanded the OCD and related disorders dimensional scales to include the four major symptom dimensions of OCD, and found that the expanded scale showed excellent psychometric properties and correlations with well-being and mental health. The results indicate that the expanded OCRD-D may serve as a unified way to assess symptoms across the major symptom dimensions of OCD and related disorders.

Summary: Hoarding behavior can improve people's ability to resist risks, but excessive hoarding reduces quality of life. The COVID-19 pandemic leads to hoarding behavior and economic problems. Educational background and social status have different effects on hoarding behavior, and negative emotions mediate this relationship.

Summary: Tourette syndrome (TS) is characterized by vocal and motor tics, often accompanied by psychiatric comorbidities. Differential diagnosis between tics and OCD-related phenomena can be challenging, as some symptoms may overlap. "Just right" phenomena are common in patients with TS, showing similarities with both tics and OCD. Treatment strategies for tics and OCD in TS patients should take into consideration these complexities.

Summary: Obsessive Compulsive Disorder (OCD) is a common mental disorder that causes great suffering and affects social functioning and quality of life. However, it is often not adequately diagnosed or diagnosed with delay, leading to a long delay in receiving proper treatment. Various factors contribute to the complexity of OCD, making it important for clinicians to evaluate all aspects of the disorder.

Summary: This study conducted a systematic review on the relationships between childhood trauma and obsessive-compulsive symptoms (OCS) severity. The results showed a significant relationship between exposure to childhood trauma and OCS severity in both clinical and non-clinical populations. It was also found that a range of childhood trauma types, rather than a single type, was associated with OCD.

Summary: Obsessive-compulsive disorder (OCD) is a heritable, polygenic disorder with contributions from both common and rare genetic variants. Genetics play an important role in the susceptibility to OCD, with discrete OCD symptom dimensions having both shared and unique genetic risks. Genome-wide studies show that OCD shares genetic risk with its comorbid conditions.

Summary: The study found that hoarding, obsessing, and depression symptoms were positively linked to Internet use disorder severity, with hoarding having the greatest diagnostic power and accuracy. Individuals with mild to moderate Internet use disorder were characterized by a network of strong and positive associations of affective and obsessive-compulsive symptoms. These findings may encourage future longitudinal studies to identify potential clinical criteria for diagnosing Internet use disorder and treatment targets.

Summary: This study found that childhood maltreatment has both direct and indirect effects on obsessive-compulsive symptoms, with the indirect effect mediated by the behavioral inhibition system. The findings highlight the role of the behavioral inhibition system in linking childhood maltreatment to obsessive-compulsive symptomology.
