Incidental learning of appropriate stimulus-response associations is crucial for optimal functioning within our complex environment. Positive and negative prediction errors (PEs) serve as neural teaching signals within distinct ('direct'/'indirect') dopaminergic pathways to update associations and optimize subsequent behavior. Using a computational reinforcement learning model, we assessed learning from positive and negative PEs on a probabilistic task (Weather Prediction Task - WPT) in three populations that allow different inferences on the role of dopamine (DA) signals: (1) Healthy volunteers that repeatedly underwent [(11)C]raclopride Positron Emission Tomography (PET), allowing for assessment of striatal DA release during learning, (2) Parkinson's disease (PD) patients tested both on and off L-DOPA medication, (3) early Huntington's disease (HD) patients, a disease that is associated with hyper-activation of the 'direct' pathway...

: Background/Study Context: Depression is a common psychiatric disorder in the elderly that leads to a decrease in quality of life and functional impairment, among other health problems. The study of depressive symptoms in institutionalized elderly is scarce in Latin America and can contribute to plan prevention and treatment actions in order to improve health conditions for the residents as well as quality of life. Therefore, the aim of this study is to determine the prevalence of depressive symptoms and identify its associated factors in institutionalized elderly...

BACKGROUND: Risks prediction models of 30-day all-cause hospital readmissions are multi-factorial. Severity of illness (SOI) and risk of mortality (ROM) categorized by All Patient Refined Diagnosis Related Groups (APR-DRG) seem to predict hospital readmission but lack large sample validation. Effects of risk reduction interventions including providing post-discharge outpatient visits remain uncertain. We aim to determine the accuracy of using SOI and ROM to predict readmission and further investigate the role of outpatient visits in association with hospital readmission...

OBJECTIVE: It has been widely acknowledged that the community and health professionals hold negative attitudes toward patients with impaired mental health. This constitutes a majör obstacle for those patients in coping with their disease, managing their care, and hence regulating their lives. Although studies carried out in Turkey document the presence of stigma, they provide limited information about the ways for solving this problem. Drawing on the litrature, the present study investigated the effect of medical education on stigmatization...

Anxiety is a common yet frequently overlooked psychiatric symptom in patients with ESRD treated with hemodialysis (HD). Anxiety is characterized by disruptive feelings of uncertainty, dread, and fearfulness. A variety of common medical complaints may be manifestations of an anxiety disorder, including palpitations, tremors, indigestion, numbness/tingling, nervousness, shortness of breath, diaphoresis, and fear. It is essential for the clinician to rule out specific medical conditions, including cardiovascular, pulmonary, and neurologic diseases, before ascribing these symptoms to an anxiety disorder...

The concept that fevers can improve the condition of patients with certain medical and psychiatric diseases dates back to Hippocrates. Over the centuries, it has been observed that fevers and infectious agents have been beneficial for a broad spectrum of diseases, including neurologic conditions such as epilepsy and psychiatric illnesses including melancholy and psychosis. Interest in the concept of fever as a treatment for disease, termed pyrotherapy or pyretotherapy, peaked in the late 1800s and early 1900s thanks to the Nobel Prize winning work of Julius Wagner-Jauregg for his studies with malaria therapy for general paralysis of the insane, now more commonly referred to as neurosyphilis...

OBJECTIVE: To evaluate associations between binge-eating disorder (BED) and somatic illnesses and determine whether medical comorbidities are more common in individuals who present with BED and comorbid obesity. METHOD: Cases (n = 850) were individuals with a BED diagnosis in the Swedish eating disorders quality registers. Ten community controls were matched to each case on sex, and year, month, and county of birth. Associations of BED status with neurologic, immune, respiratory, gastrointestinal, skin, musculoskeletal, genitourinary, circulatory, and endocrine system diseases were evaluated using conditional logistic regression models...

In monosymptomatic hypochondriacal psychosis (MHP), such as delusional infestation (DI), the patient has a fixed, false, encapsulated belief associated with tactile hallucinations (TH), most commonly formication, which is defined as cutaneous sensations of crawling, stinging, biting, etc., without evidence of infestation. Drug-induced TH should be considered in patients with suspected MHP. Although recreational drugs such as cocaine, amphetamines, and narcotics are well known to induce TH, many busy practicing dermatologists may not be familiar with other types of medications that can induce TH...

BACKGROUND: Niemann-Pick type C (NP-C) is a rare autosomal recessive progressive neurodegenerative disorder caused by mutations in the NP-C 1 or 2 gene. Besides visceral symptoms, presentation in adolescent and adult onset variants is often with neurological symptoms. The most frequently reported presenting symptoms of NP-C in adulthood are psychiatric symptoms (38 %), cognitive decline (23 %) and ataxia (20 %). Myoclonus can be present, but its value in early diagnosis and the evolving clinical phenotype in NP-C is unclear...

INTRODUCTION: The refugee crisis is a great challenge to the social and healthcare system in European countries, especially in Germany. An abundance of data has been published on the refugees' health problems (infections as well as physical diseases and psychiatric problems) and their prevention (i.e., sanitary and vaccination programs). However, data on prevalences of multidrug-resistant organisms (MDRO) in refugees are scarce, although it is known that most refugees are from or travelled through countries with high prevalences of MDRO...

BACKGROUND: Mood disorders are managed predominantly in primary care. However, general practitioners' (GPs) ability to detect and diagnose patients with mood disorders is still considered unsatisfactory. The aim of the present study was to identify predictors for the early recognition of depressive disorder (DD) and bipolar disorder (BD) in general practice. METHODS: A cohort of 1,144,622 patients (605,285 women, 539,337 men) was investigated, using the Health Search IMS Health Longitudinal Patient Database...

Alpers-Huttenlocher syndrome (AHS) is a mitochondrial DNA-depletion syndrome. Age of onset is bimodal: early onset at 2-4 years and later adolescent onset at 17-24 years of age. Early development is usually normal, with epilepsy heralding the disorder in ~50% of patients. The onset of seizures is coupled with progressive cognitive decline. Hepatopathy is variable, and when present is a progressive dysfunction leading to liver failure in many cases. These features of seizures, cognitive degeneration, and hepatopathy represent the "classic triad" of AHS...

BACKGROUND: Sudden cardiac death (SCD) occurs three times more often in psychiatric patients than in the general population. QRS fragmentation (QRSfr) and signal-averaged electrocardiography (SAECG) are simple, inexpensive, readily available tools for detecting the presence of abnormal depolarization and late potentials (LPs) in these patients, a result of either the underlying disease or treatment. METHODS: Frequency of LP detection by SAECG and QRSfr was studied in 52 psychiatric patients and compared with 30 healthy (without known structural heart disease or occurrence of ventricular arrhythmia) controls...

Background Cushing's Syndrome (CS) is associated with a specific spectrum of dementia-like symptoms, including psychiatric disorders, such as major depression, anxiety and mania, and neurocognitive alterations, like impairment of memory and concentration. This pattern of clinical complications, which significantly impair the health-related quality of life of CS patients, is sometimes referred to as "steroid dementia syndrome" (SDS). The SDS is the result of anatomical and functional anomalies in brain areas involved in the processing of emotion and cognition, which are only partially restored after the biochemical remission of the disease...

BACKGROUND: Visual hallucinations (VHs) are frequent non-motor complication of Parkinson's disease (PD), associated to a negative prognosis. Previous studies showed an association between dopamine receptor (DR) gene (DR) variants and psychosis in Alzheimer's disease, addictions, schizophrenia, and bipolar disorder. However, there are only a few studies on DR variants and VHs in PD, which did not provide conclusive results. OBJECTIVES: The present study aimed to determine whether genetic differences of DR are associated with visual hallucinations (VHs) in a cohort of Parkinson's disease (PD) patients...
