The caudate nucleus has been thought to be involved in the control of motor commands by the cerebrum, and recent studies suggest that it may play a role in the control of attachment behavior, cognition, emotion, and mental functions. Implied by the basal ganglia's involvement in the execution, planning and control of movement, the caudate nucleus functions in a situation-dependent manner where processing of external stimuli is important on the basis of learning and memory. Sensory processing, which determines the response to external stimuli, has been shown to be related to various brain regions but it remains unknown how sensory processing is associated with the structure of the caudate nucleus and white matter microstructures of the caudate.

Unlabelled: Few studies have compared the effectiveness of internet-based cognitive behavior therapy (ICBT) for obsessive-compulsive disorder (OCD) with treatment as usual (TAU). We investigated the effectiveness of guided ICBT for patients with OCD. This prospective, randomized, controlled, assessor-blinded, multicenter clinical trial was conducted at three facilities in Japan from January 2020 to March 2021.

Individuals with autism spectrum disorders (ASDs) exhibit atypical sensory characteristics, impaired social skills, deficits in verbal and nonverbal communication, and restricted and repetitive behaviors. The relationship between sensory characteristics and brain morphological changes in ASD remains unclear. In this study, we investigated the association between brain morphological changes and sensory characteristics in individuals with ASD using brain image analysis and a sensory profile test.

Background: Liver resection for hepatocellular carcinoma beyond the Barcelona Clinic Liver Cancer criteria remains controversial. Strict candidate selection is crucial to achieve optimal results in this population. This study explored postoperative outcomes and developed a preoperative predictive formula to identify patients most likely to benefit from liver resection.

Sensory processing and behaviors are altered during the development of connectivity between the sensory cortices and multiple brain regions in an experience-dependent manner. To reveal the relationship between sensory processing and brain white matter, we investigated the association between the Adolescent/Adult Sensory Profile (AASP) and neural connectivity in the white matter tracts of 84 healthy young adults using diffusion tensor imaging (DTI). We observed a positive relationship between AASP scores (i.

Background: Laparoscopic liver resection (LLR) has evolved as a safe and effective alternative to conventional open liver resection (OLR) for malignant lesions. However, LLR in cirrhotic patients remains challenging. This study analyzed the perioperative and oncological outcomes of LLR for hepatocellular carcinoma (HCC) with cirrhosis compared with OLR using propensity score matching.

Purpose: The number of elderly patients with colorectal cancer (CRC) treated with surgery has gradually increased. The aim of this study was to evaluate the short-term outcomes in patients ≥80 years of age who underwent laparoscopic or open surgery for CRC using a propensity score-matched analysis to make uniform the patient background characteristics affecting the postoperative morbidity and mortality.

Methods: We compared the short-term outcomes of open vs.

Background: People who suffer from severe mental disorder experience high rates of unemployment. Supported employment is an approach to vocational rehabilitation that involves trying to place clients in competitive jobs without any extended preparation. The Individual placement and support (IPS) model is a carefully specified form of supported employment.

Background: Although pharmacological and psychological interventions are both effective for major depression, in primary and secondary care settings antidepressant drugs remain the mainstay of treatment. Amongst antidepressants many different agents are available. Duloxetine hydrochloride is a dual reuptake inhibitor of serotonin and norepinephrine and has been licensed by the Food and Drug Administration in the US for major depressive disorder (MDD), generalised anxiety disorder, diabetic peripheral neuropathic pain, fibromyalgia and chronic musculoskeletal pain.

Background: Mirtazapine has a unique mechanism of antidepressive action and is one of the commonly used antidepressants in clinical practice.

Objectives: The aim of the present review was to assess the evidence on the efficacy and acceptability of mirtazapine compared with other antidepressive agents in the acute-phase treatment of major depression in adults.

Search Methods: We searched the Cochrane Collaboration Depression, Anxiety and Neurosis review group's specialised register (CCDANCTR), which includes relevant randomised controlled trials from the following bibliographic databases: The Cochrane Library (all years to April 2011), EMBASE, (1980 to July 2011) MEDLINE (1950 to July 2011) and PsycINFO (1974 to July 2011).

Recent neuroimaging studies have suggested that different symptom dimensions are mediated by partially distinct neural systems in obsessive-compulsive disorder (OCD). However, the correlations between neuropsychological profiles and symptom dimensions in OCD are unknown. The aim of this study was to examine the extent to which OCD symptom dimensions were associated with episodic memory and attention and executive functions.

Background: Fluvoxamine, one of the oldest selective serotonin reuptake inhibitors (SSRIs), is prescribed to patients with major depression in many countries. Several studies have previously reviewed the efficacy and tolerability of fluvoxamine for the treatment of major depression. However, these reviews are now outdated.

Background: Sulpiride may be used in combination with other antipsychotic drugs in the hope of augmenting effectiveness - especially for those whose schizophrenia has proved resistant to treatment.

Objectives: To evaluate the effects of sulpiride augmentation versus monotherapy for people with schizophrenia.

Search Strategy: We searched the Cochrane Schizophrenia Group Trials Register (July 2009) which is based on regular searches of CINAHL, EMBASE, MEDLINE and PsycINFO.

This is the protocol for a review and there is no abstract. The objectives are as follows: To review the effectiveness of supported employment compared to other approached to vocational rehabilitation and treatment as usual.Secondary objectives are to establish how far: fidelity to the IPS model affects the effectiveness of supported employment,the effectiveness of supported employment can be augmented by the addition of other interventions.

Background: Mirtazapine has a unique mechanism of antidepressant action, and thus is thought to have a different profile of adverse events from that of other antidepressants.

Objective: To present a methodologically rigorous systematic review of the adverse event profile of mirtazapine and point to possible problems with safety reporting in randomized controlled trials (RCTs) of the acute-phase treatment of major depression in adults with mirtazapine in comparison with other types of antidepressant.

Methods: The Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Register was electronically searched using the following search terms: 'depress*', 'dysthymi*', 'adjustment disorder*', 'mood disorder*', 'affective disorder', 'affective symptoms' and 'mirtazapine'.

Background: Although pharmacological and psychological interventions are both effective for major depression, antidepressant drugs are frequently used as first-line treatment in primary and secondary care settings. Milnacipran, a dual serotonin-norepinephrine reuptake inhibitor (SNRI), is one of the antidepressant drugs that clinicians use for routine depression care.

Objectives: To assess the evidence for the efficacy, acceptability and tolerability of milnacipran in comparison with tricyclic antidepressants (TCAs), heterocyclics, SSRIs and other newer antidepressive agents in the acute-phase treatment of major depression.

Neuroimaging studies have suggested that behavior therapy (BT) might change abnormal activity in the frontal-subcortical circuits of the brain in patients with obsessive-compulsive disorder (OCD). However, the results of these studies have been rather inconsistent. The aim of the present study was to use statistical parametric mapping (SPM) analysis to explore the effects of successful BT on regional cerebral blood flow (rCBF) in patients with OCD.
