Background: The hippocampus has recently been identified to play a key role in the pathophysiology of adult obsessive-compulsive disorder (OCD). Surprisingly, there is only limited evidence regarding the potential relationships with symptom dimensions. Due to the heterogeneity of symptoms in OCD, we aimed at further examining, whether hippocampal volume differences might be related to symptom profiles instead of single symptom dimensions. Methods: In order to find out more about the potential association between clinical symptom profiles and alterations in hippocampal volume we categorized a large sample of OCD patients (N = 66) into distinct symptom profile groups using K-means clustering...

Patients with major affective disorders (MAFD) with comorbid anxiety show a greater functional impairment than those without anxiety. The aim of this study is to delineate the associations between severity of anxiety in MAFD, namely bipolar disorder (BD) and major depression (MDD), and MAFD characteristics and serum high-density lipoprotein (HDL)-cholesterol levels. Recruited were 82 participants with anxiety disoders and 83 without anxiety disoders, including 101 MAFD patients and 51 healthy controls. We used the Hamilton Anxiety Rating Scale (HAM-A) to measure severity of anxiety and made the diagnoses of posttraumatic stress disorder (PTSD), obsessive compulsive disorder (OCD), panic disorder (PD), generalized anxiety disorder (GAD) and phobias...

Deep brain stimulation (DBS) is a well-established therapy for Parkinson's disease and other movement disorders. An accumulating body of evidence supports the extension of DBS application for the treatment of refractory psychiatric disorders. The ventral capsule/ventral striatum (VC/VS) is the most common anatomical target for obsessive-compulsive disorder (OCD), addiction, and depression. However, no specific electrode is available for the clinical targeting of these areas for DBS. According to the anatomical features of the VC/VS, a novel electrode was developed for simultaneous and independently programmed stimulation of the nucleus accumbens (NAc) and the anterior limb of the internal capsule (ALIC)...

These case reports focus on a rapid treatment for persistent complex bereavement disorder and posttraumatic stress disorder (PTSD), which appears to activate the mirror neuron network. Simulated reattachment is a technique which has been found to repair phantom limb pain in just a few sessions. The same neuroplasticity that accomplishes phantom pain relief has been found to occur in the treatment of complicated grief and PTSD using similar methods. The simulated reattachment for the client in Case one was found to significantly reduce the symptoms of both complicated grief and obsessive-compulsive disorder (OCD) within one session...

People with obsessive-compulsive disorder [OCD] frequently suffer from depression, a comorbidity associated with greater symptom severity and suicide risk. We examined the associations between OCD and depression symptoms in 87 adolescents with primary OCD. We computed an association network, a graphical LASSO, and a directed acyclic graph (DAG) to model symptom interactions. Models showed OCD and depression as separate syndromes linked by bridge symptoms. Bridges between the two disorders emerged between obsessional problems in the OCD syndrome, and guilt, concentration problems, and sadness in the depression syndrome...

BACKGROUND: Obsessive-compulsive disorder (OCD) symptoms within the context of a bipolar disorder (BD) have been described since the 19th century. Interestingly, the existence of a relevant overlap between the aforementioned psychiatric syndromes has been confirmed by a number of recent epidemiological and family studies. AIMS: The aim of the present paper is to review the clinical features and the therapeutic implications of the OCD-BD comorbidity. DISCUSSION: In the last two decades, the frequent association between OCD and BD has been earning a growing interest given its relevant nosological and therapeutic implications...

OBJECTIVE: Emotion regulation difficulties are implicated in psychological disorders but their role in obsessive-compulsive disorder (OCD) is unclear. Two studies examining these difficulties in OCD are presented. METHOD: A community sample (Study 1; n = 306) and a clinical OCD sample (Study 2; n = 59) completed the Difficulties in Emotion Regulation Scale (DERS) and measures of depression, anxiety, and OCD. In Study 2, the OCD sample was compared to a matched control group (n = 59, selected from Study 1)...

Obsessive-compulsive disorder (OCD) is a distressing and often debilitating disorder characterized by obsessions, compulsions, or both that are time-consuming and cause impairment in social, occupational, or other areas of functioning. There are many published studies reporting higher risk of suicidality in OCD patients, as well as studies describing increased risk of suicidality in OCD patients with other comorbid psychiatric conditions such as major depressive disorder (MDD) and posttraumatic stress disorder (PTSD)...

Despite various lines of evidence implicating impaired decision-making ability in individuals with obsessive-compulsive disorder (OCD), neuropsychological investigation has generated inconsistent findings. Although the cortico-striato-thalamo-cortical (CSTC) circuitry has been suggested, the involvement of the cortex has not yet been fully demonstrated. Moreover, it is unknown whether surgical intervention on the CSTC circuitry results in a predicted improvement of decision-making ability of OCD. Here we present a study of decision making based on the Iowa Gambling Task (IGT) to investigate decision making in a large sample of individuals with treatment-resistant OCD with and without anterior capsulotomy (AC)...

Obsessive-compulsive disorder (OCD) commonly co-occurs with depression, resulting in heightened severity and poorer treatment response. Research on the associations between specific obsessive-compulsive symptoms (OCS) and depressive symptoms has utilized measures that have not fully considered the relationship across OCS dimensions. Little is known about which factors explain the overlap between OCS and depressive symptoms. OCS and depressive symptoms may be related via depressive cognitive styles, such as rumination or dampening (i...

Tourette's Syndrome (TS) is a complex disorder characterized by repetitive, sudden, and involuntary movements or vocalizations, called tics. Tics usually appear in childhood, and their severity varies over time. In addition to frequent tics, people with TS are at risk for associated problems including attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety, depression, and problems with sleep. TS occurs in most populations and ethnic groups worldwide, and it is more common in males than in females...

Depression is a commonly-occurring symptom in obsessive-compulsive disorder (OCD), and is associated with worse functional impairment, poorer quality of life, and poorer treatment response. Understanding the underlying neurochemical and connectivity-based brain mechanisms of this important symptom domain in OCD is necessary for development of novel, more globally effective treatments. To investigate biopsychological mechanisms of comorbid depression in OCD, we examined effective connectivity and neurochemical signatures in the pregenual anterior cingulate cortex (pACC), a structure known to be involved in both OCD and depression...

REVIEW
Umberto Albert, Alessandra Baffa, Giuseppe Maina
The term accommodation has been used to refer to family responses specifically related to obsessive-compulsive (OC) symptoms: it encompasses behaviors such as directly participating in compulsions, assisting a relative with obsessive-compulsive disorder (OCD) when he/she is performing a ritual, or helping him/her to avoid triggers that may precipitate obsessions and compulsions. At the opposite side, family responses to OCD may also include interfering with the rituals or actively opposing them; stopping accommodating OC symptoms or actively interfering with their performance is usually associated with greater distress and sometimes even with aggressive behaviors from the patients...

BACKGROUND: Pediatric obsessive-compulsive disorder (OCD) is associated with deleterious familial effects; caregivers are often enmeshed in the disorder and can experience considerable burden and decreased quality of life (QoL). Consequently, this study examined burden and QoL in caregivers of youth with OCD enrolled in an intensive outpatient or partial hospitalization program. METHOD: The relationships between caregiver QoL and burden and the following variables were investigated: OCD symptom severity, functioning (youth functional impairment, general family functioning), family (family accommodation, parental relationship satisfaction, positive aspects of caregiving), and comorbid psychopathology (caregiver anxiety and depressive symptoms, youth internalizing and externalizing behaviors)...

BACKGROUND: In 2010, we published an often-cited case report describing smoking cessation and substantial weight loss after deep brain stimulation (DBS) for obsessive-compulsive disorder (OCD) in an obese patient. To test whether this single observation was also observed in the treated population at large, the weight changes of a larger cohort of patients who underwent DBS for OCD or major depressive disorder (MDD) were studied. RESULTS: Data were available for 46 patients (30 OCD and 16 MDD patients; mean age 46...
