BACKGROUND: Schizophrenia (SZ) and bipolar disorder (BD) are characterized by different clinical symptoms, and have previously been considered as categorically separate. However, several lines of evidence controversially suggest that these two disorders may run on a continuum. While it is therefore important to evaluate the subtle differences between SZ and BD, few studies have investigated the difference of brain functioning between the two by focusing on the common symptoms of cognitive functioning and impulsivity, rather than positive/negative and mood symptoms...

Since many years a correlation between neuropsychiatric disorders and eating disorders resulting in obesity is well established. According to different studies, 1.2 - 4 % of patients scheduled for bariatric surgery are taking lithium as a mood stabilizer treatment for bipolar disorder. We are presenting a case of lithium toxicity after vertical sleeve gastrectomy surgery in a 40 years-old female. The patient developed severe neurological and renal signs needing an intensive care unit admission and continuous veno-venous hemodiafiltration...

Mitochondria play a crucial role in neuronal function, especially in energy production, the generation of reactive oxygen species, and calcium signaling. Multiple lines of evidence have suggested the possible involvement of mitochondrial deficits in major psychiatric disorders, such as schizophrenia and bipolar disorder. This review will outline the current understanding of the physiological role of mitochondria and their dysfunction under pathological conditions, particularly in psychiatric disorders. The current knowledge about mitochondrial deficits in these disorders is somewhat limited because of the lack of effective methods to dissect dynamic changes in functional deficits that are directly associated with psychiatric conditions...

The present study describes a new mixed program of psychoeducational and psychological interventions for bipolar patients, applicable during everyday practice. Thirty-two bipolar patients recruited at a psychiatric day-hospital service have been admitted to a program consisting of 30 meetings and 2 follow-ups at 6 and 12 months. The psychoeducational support determined a general improvement of all included patients. At baseline, patients with residual depression had higher Hamilton Depression Rating Scale (HDRS) scores than euthymic patients (mean score ± SD: 21...

INTRODUCTION: High frequency oscillations (HFOs) embedded within the somatosensory evoked potential (SEP) are not routinely recorded/measured as part of standard clinical SEPs. However, HFOs could provide important additional diagnostic/prognostic information in various patient groups in whom SEPs are tested routinely. One area is the management of patients with hypoxic ischaemic encephalopathy (HIE) in the intensive care unit (ICU). However, the sensitivity of standard clinical SEP recording techniques for detecting HFOs is unknown...

Schizophrenia and bipolar disorder are common, severe, and disabling psychotic disorders, which are difficult to research. We argue that the genetically determined neurodevelopmental disorder Prader-Willi syndrome (PWS), which is associated with a high risk of affective psychotic illness, can provide a window into genetic mechanisms and associated neural pathways. People with PWS can all show non-psychotic psychopathology and problem behaviours, but the prevalence of psychotic illness differs markedly by genetic subtype; people with PWS due to chromosome 15 maternal uniparental disomy have higher prevalence of psychotic illness compared with patients with PWS due to 15q11-13 deletions of paternal origin...

Bipolar disorder (BD) is a major health problem. It causes significant morbidity and imposes a burden on the society. Available treatments help a substantial proportion of patients but are not beneficial for an estimated 40-50%. Thus, there is a great need to further our understanding the pathophysiology of BD to identify new therapeutic avenues. The preponderance of evidence pointed towards a role of protein kinase C (PKC) in BD. We reviewed the literature pertinent to the role of PKC in BD. We present recent advances from preclinical and clinical studies that further support the role of PKC...

Diogenes syndrome (DS) is not a specific disease but a real neurobehavioral syndrome, characterized by severe domestic squalor, pathological hoarding, lack of insight into the condition, and no need for help. DS can be secondary when associated to psychosis or bipolar disorder, or primary when it occurs as a single entity, usually in the elderly. DS is a clinically complex transnosographic syndrome for which multidimensional approaches need to be considered: medical, psychiatric, neurological, social, scientific, and ethical...

The concept of the bipolar-spectrum and of mixed features being a bridge between major depressive disorders and bipolar disorders (BDs) has become increasingly important in mood-disorder diagnoses. Under these circumstances, antidepressants (ADs) and mood stabilizers (MSs) should be used with caution in the treatment of major depressive episodes (MDEs) and to obtain long-term stability in BDs. Before treating MDEs, screening tools, specific symptom evaluation and medical history should be used to distinguish between bipolarity and mixed features in patients for whom AD monotherapy may present a risk...

BACKGROUND: People with long-term serious mental illness live with severe and debilitating symptoms that can negatively influence their health and quality of life, leading to outcomes such as premature mortality, morbidity and obesity. An interplay of social, behavioural, biological and psychological factors is likely to contribute to their poor physical health. Participating in regular physical activity could bring symptomatic improvements, weight loss benefits, enhanced wellbeing and when undertaken in a community-based group setting can yield additional, important social support benefits...

Objective: The hot flash is a common vasomotor disorder that causes distress in menopausal women and that can be debilitating in men with prostate cancer who are treated with androgen deprivation therapy (ADT). The utility of auricular electroacupuncture (AEA) was tested exclusively for a small cohort of men with ADT-induced vasomotor symptoms while the men underwent a course of curative radiotherapy. Materials and Methods: Prior to and during radiotherapy treatment, men with vasomotor symptoms were given repeated questionnaires regarding severity and frequency of hot flashes, quality of life (QoL), and sleep over a 6-week span of an AEA protocol...

Bipolar disorder is characterized by recurrent manic and depressive episodes. Patients suffering from this disorder experience dramatic mood swings with a wide variety of typical behavioral facets, affecting overall activity, energy, sexual behavior, sense of self, self-esteem, circadian rhythm, cognition, and increased risk for suicide. Effective treatment options are limited and diagnosis can be complicated. To overcome these obstacles, a better understanding of the neurobiology underlying bipolar disorder is needed...

BACKGROUND: The mechanisms underlying self-perpetuation of persistent atrial fibrillation (AF) are not well understood. To gain insight into these mechanisms, we conducted a study comparing left atrial (LA) electroanatomic maps obtained during sinus rhythm between patients with paroxysmal AF (PAF) and patients with persistent AF (PerAF). METHODS: The study included 23 men with PAF (age, 56.3±12.1 years) and 13 men with PerAF (age, 54.3±13.4 years). LA voltage mapping was performed during sinus rhythm...

OBJECTIVE: To examine the impact of coercive interventions (CI) on patients' evaluations of psychiatric hospitals as adversaries versus allies. METHODS: Self-constructed interviews were conducted relating to quantitative and subjective aspects of coercion and the attitude towards psychiatry of 79 patients with psychotic and bipolar disorders. The Coercion Experience Scale (CES) and the Admission Experience Survey (AES) were used to establish the subjective impact of CI...

The current card sort exercise described by Agius et al. in 2006 provides a tool for patients and their families to characterise the temporal pattern of occurrence of both stereotyped and idiosyncratic prodromal symptoms that serve as early warning signs predicting a relapse. This 'individual relapse signature' is highly specific for bipolar relapse, and aids identification of a relapse such that patients can be channeled into appropriate early intervention pathways. This review examines the role of the card sort exercise in the treatment of bipolar disorder, and evaluates the evidence for its efficacy...

Psychiatric disorders represent a great medical and social challenge and people suffering from these conditions face many impairments regarding personal and professional life. In addition, a mental disorder will manifest itself in approximately one quarter of the world's population at some period of their life. Dysfunction in energy metabolism is one of the most consistent scientific findings associated with these disorders. With this is mind, this review compiled data on disturbances in energy metabolism found by proteomic analyses of postmortem brains collected from patients affected by the most prevalent psychiatric disorders: schizophrenia (SCZ), bipolar disorder (BPD), and major depressive disorder (MDD)...

PURPOSE: It is unknown which retinal cells are involved in the retina-to-sclera signaling cascade causing myopia. As inherited retinal dystrophies (IRD) are characterized by dysfunction of a single retinal cell type and have a high risk of refractive errors, a study investigating the affected cell type, causal gene, and refractive error in IRDs may provide insight herein. DESIGN: Case-control study. METHODS: Study Population: Total of 302 patients with IRD from 2 ophthalmogenetic centers in the Netherlands...

INTRODUCTION: The right atrium (RA) is readily accessible; however, it is unclear whether changes in the RA are representative of the LA. We performed detailed biatrial electroanatomic mapping to determine the electrophysiological relationship between the atria. METHODS AND RESULTS: Consecutive patients with persistent AF underwent biatrial electroanatomical mapping with a contact force catheter acquiring points with a CF >10 g prior to ablation. Points were analyzed for tissue voltage, complex electrograms, low voltage (<0...

Machine learning techniques provide new methods to predict diagnosis and clinical outcomes at an individual level. We aim to review the existing literature on the use of machine learning techniques in the assessment of subjects with bipolar disorder. We systematically searched PubMed, Embase and Web of Science for articles published in any language up to January 2017. We found 757 abstracts and included 51 studies in our review. Most of the included studies used multiple levels of biological data to distinguish the diagnosis of bipolar disorder from other psychiatric disorders or healthy controls...

Recurrent shoulder instability in young contact athletes has been well established. The importance of bipolar bone loss in instability has come to the forefront in terms of proper management of this condition. It remains controversial, however, which patients would be better served with an arthroscopic versus open procedure and when additional procedures may reduce the risk of failure (i.e., remplissage). We present our arthroscopic technique of a panlabral repair with concomitant remplissage using the double-pulley technique...
