REVIEW
Patricia Tsui, Andrew Deptula, Derek Y Yuan
PURPOSE OF REVIEW: This paper examines the overlap of conversion disorder with chronic pain conditions, describes ways to assess for conversion disorder, and provides an overview of evidence-based treatments for conversion disorder and chronic pain, with a focus on conversion symptoms. RECENT FINDINGS: Conversion disorder is a significant problem that warrants further study, given that there are not many well-established guidelines. Accurate and timely assessment should help move treatment in a more fruitful direction and avoid unnecessary medical interventions...

OBJECTIVE: The Human Immunodeficiency Virus (HIV) has an impact on the brain, even when the infection is well-controlled with modern highly-active antiretroviral therapy (HAART). While dementia is rare in those on HAART, milder cognitive impairment is common. The causes, patterns, and evolution of brain dysfunction in people living with HIV remain uncertain. We evaluate whether electrophysiological methods provide informative measures of brain dysfunction in this population. METHODS: A systematic literature search identified studies that used EEG or MEG to evaluate persons living with HIV published between 1996 (when HAART became available) and 2016...

Mood disorders are wide spread with estimates that one in seven of the population are affected at some time in their life (Kessler et al., 2012). Many of those affected with severe depressive disorders have cognitive deficits which may progress to frank neurodegeneration. There are several peripheral markers shown by patients who have cognitive deficits that could represent causative factors and could potentially serve as guides to the prevention or even treatment of neurodegeneration. Circadian rhythm misalignment, immune dysfunction and oxidative stress and circadian rhythm misalignment are key pathologic processes implicated in neurodegeneration and cognitive dysfunction in depressive disorders...

The pathophysiological underpinnings of neuroprogressive processes in recurrent major depressive disorder (rMDD) are reviewed. A wide array of biochemical processes underlie MDD presentations and their shift to a recurrent, neuroprogressive course, including: increased immune-inflammation, tryptophan catabolites (TRYCATs), mitochondrial dysfunction, aryl hydrocarbonn receptor activation, and oxidative and nitrosative stress (O&NS), as well as decreased sirtuins and melatonergic pathway activity. These biochemical changes may have their roots in central, systemic and/or peripheral sites, including in the gut, as well as in developmental processes, such as prenatal stressors and breastfeeding consequences...

Overwhelming evidence indicates the involvement of immune-inflammatory processes in the pathophysiology of major depressive disorder (MDD). Peripheral cytokine alterations serve as one of most consistently reported indices of subthreshold inflammatory state observed in MDD. Although cytokines cannot pass directly through the blood-brain barrier, a number of transport mechanisms have been reported. In addition, peripheral cytokines may impact central nervous system via downstream effectors of their biological activity...

Kaylee Misener, Maya Libben
The current study used a semantic priming paradigm to investigate the presence of implicit interpretation biases for food and body shape words among 118 undergraduate females. Reaction times (RTs) were recorded while participants made lexical decisions (i.e., word vs. non-word judgments) to lexical targets that were preceded by negatively valenced eating disorder related (e.g., fat-PIZZA), eating disorder unrelated (e.g., party-PIZZA), or semantically unrelated (e.g., umbrella-PIZZA) prime words. Self-reported eating disorder traits were assessed using the Body Shape Questionnaire (BSQ-34), the Eating Attitudes Test (EAT-26), and the Eating Disorder Examination (EDE-Q 6...

REVIEW
T W Robbins
This Review advances the case that bidirectional, cross-species translation of findings from experimental animals to and from humans is an important strategy for drug discovery. Animal models of mental disorders require appropriate behavioural or cognitive outcome variables that can be generalized cross-species. One example is the treatment of impulsive behaviour in attention deficit hyperactivity disorder (ADHD) with stimulant drugs. Performance on the stop signal reaction task as an index of impulsivity is improved both in healthy human volunteers and in patients with adult ADHD by stimulant drugs and also by the selective noradrenergic reuptake blocker atomoxetine...

INTRODUCTION: Neurofibromatosis type 1 (NF1) is a common neurocutaneous syndrome often associated with specific cognitive deficits that are rarely monitored during follow-up of these patients. OBJECTIVE: The purpose of our study is two-fold. First, we aimed to describe the cognitive profile of patients with NF1 and detect disorders in higher brain functions associated with the disease. Second, we identified the reasons for consultation associated with school performance in these patients...

Sleep-disordered breathing (SDB) is highly prevalent in the general population and has been associated with cognitive impairment in older individuals. Delirium is an acute decline in cognitive function and attention that often occurs after surgery, especially in older individuals. Several recent studies suggest an association between SDB and postoperative delirium. The aim of this systematic review is to examine the current literature on SDB, postoperative delirium, and cognitive impairment and to discuss the pathophysiology and perioperative considerations...

Study Objectives: Idiopathic rapid eye movement sleep behavior disorder (iRBD) is considered as a prodromal stage of synucleinopathy. Although loss of functional connectivity is implicated in neurodegenerative diseases, network characteristics of electroencephalography (EEG) in iRBD are unknown. Therefore, we evaluated resting-state EEG functional connectivity to identify the brain network changes in patients with iRBD. Methods: We prospectively enrolled 20 patients with polysomnography-confirmed iRBD and 16 control subjects...

OBJECTIVE: Meta-analyses have documented the efficacy of cognitive-behavioral therapy (CBT) for reducing symptoms of eating disorders. However, it is not known whether CBT for eating disorders can also improve quality of life (QoL). This meta-analysis therefore examined the effects of CBT for eating disorders on subjective QoL and health-related quality of life (QoL). METHOD: Studies that assessed QoL before and after CBT for eating disorders were searched in the PsycInfo and Medline database...

REVIEW
Thomas Brandt, Marianne Dieterich
Vertigo and dizziness are among the most common complaints in neurology clinics, and they account for about 13% of the patients entering emergency units. In this Review, we focus on central vestibular disorders, which are mostly attributable to acute unilateral lesions of the bilateral vestibular circuitry in the brain. In a tertiary interdisciplinary outpatient dizziness unit, central vestibular disorders, including vestibular migraine, comprise about 25% of the established diagnoses. The signs and symptoms of these disorders can mimic those of peripheral vestibular disorders with sustained rotational vertigo...

BACKGROUND: Perinatal maternal depression is common and undertreated in many sub-Saharan African countries, including Nigeria. While culture shapes the social determinants and expression of depressive symptoms, there is a dearth of research investigating these processes in African contexts. METHODS: To address this gap, we conducted in-depth interviews with 14 women with perinatal depression, 14 of their family caregivers and 11 health providers, using the McGill Illness Narrative Interview as part of a larger trial of a stepped-care intervention...

Hada Fong-Ha Ieong, Zhen Yuan
Dependence to opiates, including illicit heroin and prescription pain killers, and treatment of the opioid use disorder (OUD) have been longstanding problems over the world. Despite intense efforts to scientific investigation and public health care, treatment outcomes have not significantly improved for the past 50 years. One reason behind the continuing use of heroin worldwide despite such efforts is its highly addictive nature. Brain imaging studies over the past two decades have made significant contribution to the understanding of the addictive properties as to be due in part to biological processes, specifically those in the brain structure and function...

Background and Purpose: Auditory processing disorders (APD), tinnitus and hearing loss (HL) are typical issues reported by patients in audiologic clinics. These auditory impairments can be concomitant or mutually excluding. APD are not necessarily accompanied by significant HL, whereas many adults exhibit peripheral HL and typical cognitive deficits often associated with APD. Since HL, tinnitus and APD affects to several parts of the ascending auditory pathway from the periphery to the auditory cortex, there could be some interrelationship between them...
