In medicine, general clinical practice moves in the direction of early detection and intervention for the prevention of progressive disease. In psychiatry, research in subjects with the risk syndrome for psychosis, has been conducted for the prevention of schizophrenia, known as a devastating chronic disease. The inclusion of 'attenuated psychosis syndrome', based on the results of early intervention studies, is one of the major issues in the upcoming DSM-V. Further investigations are needed to find biological markers and endophenotypes to supplement the diagnostic criteria. In the future, adoption of clinical staging is promising to overcome the shortcoming of current diagnosis of schizophrenia. In clinical practice, more concerns are needed about attenuated psychotic symptoms which might be risk signals for the transition to psychosis.

Prolonged disorders of consciousness comprise a spectrum of impaired consciousness where arousal is preserved with impaired awareness, which last more than 4 weeks. Vegetative state is a prototype of the prolonged disorders of consciousness. A patient in the vegetative state has no signs of awareness. The minimally conscious state is characterized by inconsistent but reproducible signs of awareness and is regarded as a transitional state of recovery of consciousness. Differentiating patients in minimally conscious state from those in vegetative state is still challenging. Utilizing standardized neurobehavioral assessment tools could improve diagnostic accuracy. Recent advances in neuroimaging and electrophysiologic tools may aid the diagnosis and prognostication. Treatment for recovery of consciousness is still limited. More research on the diagnosis and treatment of prolonged disorders of consciousness is needed not only for improved care of patients with prolonged disorders of consciousness but also a greater understanding of human consciousness.

In the present article, we provide a comprehensive review of the treatment strategies for obsessive-compulsive disorder (OCD), a common, chronic, and often debilitating disorder, characterized by overwhelming obsessions and compulsions.OCD typically starts in childhood or adolescence and persists throughout life, causing functional impairment across multiple domains. The article begins by describing the historical concepts of OCD from religious and guilt-based explanations to psychoanalytic perspectives, and then explores the changing understanding of OCD as a treatable condition. Recent advances include the development of evidence-based psychological treatments, such as exposure and response prevention, and pharmacological treatments, such as selective serotonin reuptake inhibitors. The latest version of the Diagnostic and Statistical Manual of Mental Disorders, and the International Classification of Diseases, has removed OCD from the anxiety disorder grouping and regrouped it into obsessive-compulsive and related disorders. We conclude by highlighting the current state of knowledge and development in the clinical management of OCD, including recommendations for first- and second-line treatments, alternative, or augmentative strategies for and novel agents under investigation for OCD. In future, the latest advances in neuroimaging, electrophysiology, digital technology, and data-driven analysis will help elucidate the pathophysiology of OCD and develop personalized intervention strategies.

The use of computers, especially for virtual reality (VR), to understand, assess, and treat various mental health problems has been developed for the last decade, including application for phobia, post-traumatic stress disorder, attention deficits, and schizophrenia. However, the number of VR tools addressing obsessive-compulsive disorder (OCD) is still lacking due to the heterogeneous symptoms of OCD and poor understanding of the relationship between VR and OCD. This article reviews the empirical literatures for VR tools in the future, which involve applications for both clinical work and experimental research in this area, including examining symptoms using VR according to OCD patients' individual symptoms, extending OCD research in the VR setting to also study behavioral and physiological correlations of the symptoms, and expanding the use of VR for OCD to cognitive-behavioral intervention.

OBJECTIVES: Previous studies have indicated that obsessive-compulsive disorder (OCD) is associated with high levels of impulsiveness. The aim of this study was to assess whether there are differences in clinical correlates with impulsiveness between OCD patients and healthy controls, and whether there is a significant relation between certain obsessive-compulsive symptomatic dimensions and impulsiveness. METHODS: A group of 45 OCD outpatients and 45 matched healthy controls were interviewed and diagnosed according to DSM-IV criteria. All subjects were assessed by means of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Barratt Impulsiveness Scale (BIS-11), the Hamilton Anxiety Scale (HAM-A), and the Montgomery-Asberg Depression Rating Scale (MADRS). RESULTS: Compared with healthy controls, OCD patients exhibited significantly higher BIS-11 scores except for with respect to non-planning impulsiveness. The MADRS scores and age at onset in patients with OCD were significantly correlated with BIS-11 total scores. Multiple regression analyses revealed that only age at onset showed an independent positive correlation with impulsiveness. Hoarding was the only dimension significantly associated with impulsiveness. CONCLUSION: These findings suggest that groups of patients with early onset OCD may show some association with impulsiveness, and that impulsiveness may be another distinct clinical feature of hoarding in OCD.

Antipsychotics polypharmacy is a common practice in clinical settings despite the opposition of most guidelines for treatment of schizophrenia. This article reviews the evidence of antipsychotics polypharmacy and summarizes advantages and disadvantages shown in clinical trials. Clinicians choose antipsychotics polypharmacy to control the positive and negative symptoms more effectively especially in treatment resistant patients or to reduce adverse effects. There are some theoretical possibilities that antipsychotics polypharmacy affects a broader range of receptors, enhances D2-receptor blockade and optimizes pharmacokinetic effects. Clinical evidence suggests that clozapine co-administered with risperidone, sulpiride, or amisulpride reduces psychotic symptoms in treatment-resistant patients and that aripiprazole with other antipsychotics reduces metabolic side effects. On the other hand, antipsychotics polypharmacy is associated with problems such as dose-dependent side effects, metabolic problems, increased mortality and treatment cost. Considering pros and cons, antipsychotics polypharmacy must be started after close scrutiny of the patient's medication history not just by clinical judgment. Also, changing the regimen from polypharmacy to monotherapy should be considered as a reasonable option to schizophrenic patients in stationary status.

Adherence to treatment in mental health is generally regarded as central for optimizing recovery. However, poor adherence of patients with psychiatric disorders can have devastating consequences such as relapse, rehospitalization and poor quality of life. Adherence problems are likely to be multi-determined and related to different factors in different individuals. Combining subjective and objective quantitative assessment with a more qualitative interview might help assess adherence better in patients with mental illness to determine the presence of adherence problems and investigate their cause. The therapeutic relationship between patient and clinician has been found to be important for treatment adherence. Adherence problems should be regarded not as the result but as the process of the treatments to facilitate the therapeutic alliance. Clinicians and patients need to cooperate with each other in a model of shared decision-making to choose the best treatment option for the specific individual. Psychoeducation might provide information about the risk and benefit of the medication to patients and their family. The collaborative approach is helpful for the clinicians to have an open dialogue about what patients think and perceive about the treatment.

Similar to substance use disorder, patients with Internet addiction disorder (IAD) show excessive use, tolerance and withdrawal symptoms. We report a case of a patient with withdrawal psychosis who showed persecutory delusion and disorganized behaviors in addition to common withdrawal symptoms such as agitation and irritability. A 25-year-old male developed a full-blown psychotic episode within one day after discontinuing an Internet game that he had been playing for at least eight hours a day for two years. Upon admission, he had no abnormal brain imaging findings and laboratory tests. With antipsychotic medication (quetiapine up to 800 mg), his psychotic symptoms rapidly subsided and after four days of treatment, he no longer showed any signs of psychosis. This case report suggests that brief psychosis can develop during withdrawal from long-term excessive use of an Internet and the central pathology beneath the IAD is more likely a form of addiction than impulse control.

OBJECTIVE: Although various clinical factors that affect medication adherence in schizophrenia have been studied, the role of the therapeutic alliance has not been studied in detail. Accordingly, we investigated the association between medication adherence and therapeutic alliance in patients with schizophrenia treated in a community outpatient clinic in Korea. METHODS: In this cross-sectional study, 81 outpatients who met the DSM-IV-TR criteria for schizophrenia were analyzed. Therapeutic alliance was measured via patient-self-report questionnaires consisting of 12 questions, which evaluate both “affective bond” and “collaborative bond” of alliance. We investigated the relationship between medication adherence and therapeutic alliance through correlation and regression analyses. RESULTS: Overall therapeutic alliance was weakly associated with medication adherence (r=0.268, p<0.05). Among two factors of therapeutic alliance, “affective bond” was associated with adherence (r=0.302, p<0.05), but collaborative was not. Regression analysis showed that therapeutic alliance significantly predicted medication adherence even after adjustment for duration of treatment, insight, and symptom severity. CONCLUSION: Maintaining a favorable therapeutic alliance is associated with medication adherence in schizophrenia. Further, treating patients in a frank and genuine manner might be important to improve adherence.
