Hoarding disorder studies are primarily based on persons who seek treatment and demonstrate good insight. The aim of the present study is to evaluate whether there are differences between community and treatment-seeking samples of individuals with hoarding disorder (HD).

Fourteen people with HD from the community and twenty treatment-seeking people with HD were assessed by a battery of instruments to evaluate HD features and other associated characteristics.

Compared to the treatment-seeking sample, the HD community sample was older, had poorer insight, and had a lower prevalence of comorbid obsessive-compulsive disorder (OCD). There were no differences in gender, education, presence of psychiatric comorbidities, quality of life, and hoarding behavior characteristics between the samples. The final logistic regression model with the Dimensional Obsessive-Compulsive Scale (DOCS) as the single predictor of treatment-seeking status was statistically significant, indicating that it was able to distinguish between the two samples. The model explained between 20.7% and 27.9% of the variance of subjects, and correctly classified 67.6% of cases.

Our results indicate that there appear to be few differences between the treatment-seeking and community samples of individuals with HD. The presence of comorbid OCD in treatment-seeking groups seems to be more frequent than in HD community samples.

Obsessive phenomena, when present, are usually seen in the depressive phase of bipolar disorder.

The peculiar case with aggravation in ruminative and obsessive thinking with simultaneous hypomania may widen our understanding of the phenomenology of antidepressant induced hypomanic symptoms.

We present a case of ruminative hypomania induced by high dose venlafaxine. Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HAM-D) and Yale Brown Obsessive Compulsive Scale (YBOCS) were used for symptom ratings.

The patient was 30 years old and she had treatment history of depression for 3 months. She had two consecutive suicide attempts with drugs in the week before she was hospitalized for suicidal risk. She was using venlafaxine 300 mg/day and olanzapin 2,5 mg/day; continuous ruminative thinking about the past and imaginary sexual affairs with former friends were apparent with an unremitting pattern, leading to intense psychomotor agitation and suicide attempts. Irritable mood, and increased energy was observed with continuous ruminations. She was diagnosed with bipolar-II-disorder, with mixed features and anxious distress (YMRS:17, HAM-D:22, YBOCS:34). After discontinuing venlafaxine and starting anti-manic treatment with haloperidol 10 mg/day in the first week, both affective symptoms and ruminations were improved (YMRS:2, HAM-D:4, YBOCS:8). Aripiprazol 20 mg/day and quetiapine 100 mg/day which were given for continuation treatment were also effective for preserving full remission.

When prescribing high dose venlafaxine for treatment resistant depression, it should be remembered that this may induce hypomanic symptoms and prominent ruminative thinking which can be ameliorated with anti-manic treatment.

No significant relationships.

The aim of this study is to examine the effects of quetiapine as an adjuvant treatment for obsessive–compulsive (OC) symptoms in patients with bipolar disorder (BD) type I.

In this 8-week double-blind placebo-controlled randomized clinical trial, 47 patients with BD in euthymic phase that had OC symptoms were randomly allocated to receive either quetiapine or placebo plus their routine medications (lithium + clonazepam). Yale–Brown Obsessive–Compulsive Scale (YBOCS) was used to assess the outcomes. Adverse effects were also recorded.

Of 47 BD patients with OC symptoms that were randomly allocated in two groups of quetiapine (n = 24) and placebo group (n = 23), 40 patients (20 in quetiapine group and 20 in placebo group) completed the trial. Throughout the trial, the mean score of YBOCS in the quetiapine group dropped from 24.37 ± 1.51 to 15.26 ± 1.16 (P < .001) and in the placebo group decreased from 24.21 ± 1.33 to 23.94 ± 1.66 (P = 1.97). At the end of the study, 12 (60%) patients in the quetiapine group and 1 (5%) patient in the placebo group had more than 34% decline in YBOCS score (P < .001). No serious adverse effects were reported in two groups.

Our double-blind placebo-controlled clinical trial showed that quetiapine may be an effective adjuvant agent for reducing OC symptoms in BD patients.

Obsessive-Compulsive Disorder (OCD) is a mental disorder characterized by obsessions and/or compulsions. Although some epidemiological studies take part in literature, which claim that traumatic life events in childhood ages are observed more in patients with OCD compared to healthy population, the number of these studies is limited. In this study, it is aimed to compare OCD patients with healthy volunteers in terms of traumatic life events in childhood ages.

With 25 consecutive patients who are diagnosed as OCD and whose treatment continues, 25 healthy controls equivalent in terms of sociodemographic features are included in the study. Sociodemographic Data Form, Childhood Age Trauma Quarter (CTQ) and Maudley Obsessive Compulsive Question List (MOCQL) are applied to the participants. Significance Value in statistical level is accepted as P < 0.05.

In OCD patient group, CTQ scores are found high in statistical level compared to healthy controls. It has been determined that there is a significant relationship between total score of MOCQL slowness subscale scores, subscale scores of sexual and emotional abuse, MOCQL rumination subscale scores and CTQ sexual abuse scores.

Compared to healthy controls, more findings of traumatic life event in childhood age are observed within OCD patients.

Obsession and delusion are theoretically distinct from each other in terms of reality testing. Despite such phenomenological distinction, no extant studies have examined the identification of common and distinct neural correlates of obsession and delusion by employing biologically grounded methods. Here, we investigated dimensional effects of obsession and delusion spanning across the traditional diagnostic boundaries reflected upon the resting-state functional connectivity (RSFC) using connectome-wide association studies (CWAS).

Our study sample comprised of 96 patients with obsessive–compulsive disorder, 75 patients with schizophrenia, and 65 healthy controls. A connectome-wide analysis was conducted to examine the relationship between obsession and delusion severity and RFSC using multivariate distance-based matrix regression.

Obsession was associated with the supplementary motor area, precentral gyrus, and superior parietal lobule, while delusion was associated with the precuneus. Follow-up seed-based RSFC and modularity analyses revealed that obsession was related to aberrant inter-network connectivity strength. Additional inter-network analyses demonstrated the association between obsession severity and inter-network connectivity between the frontoparietal control network and the dorsal attention network.

Our CWAS study based on the Research Domain Criteria (RDoC) provides novel evidence for the circuit-level functional dysconnectivity associated with obsession and delusion severity across diagnostic boundaries. Further refinement and accumulation of biomarkers from studies embedded within the RDoC framework would provide useful information in treating individuals who have some obsession or delusion symptoms but cannot be identified by the category of clinical symptoms alone.
