Safety-seeking behaviours are responses employed to protect against perceived threat. In relation to anxiety disorders, safety-seeking behaviours have been implicated in both the formation and maintenance of distress. Several studies have highlighted similar findings in relation to psychosis; however, this literature has not yet been synthesized. This review is, therefore, being conducted in order to synthesize the literature on safety seeking in people with psychosis to increase the understanding of this relationship...

Disturbances of gait and postural stability are characteristic of the chronic progressive vascular lesion of the brain observed in moderate to severe stages of cerebrovascular disease. Disconnections between the prefrontal cortex, basal ganglia and cerebellum due to the damage of the white matter (vascular leukoencephalopathy) underlie disturbances of gait and postural stability (shorter stride length, wider gait). There are difficulties in starting with possible stoppings during the walking, waiting in front of small barriers as well as difficulties in concentration (e...

BACKGROUND: A functional polymorphism in the catechol-O-methyltransferase (COMT) gene (Val158Met) appears to influence cognition in people with alcohol/substance use disorders (AUD/SUD) and in those with psychosis. METHODS: To explore the potential moderating effect of these factors, a cross-sectional study was conducted, randomly recruiting subjects with DSM-IV diagnosis of schizophrenia. AUD/SUD was rigorously assessed, as well as COMT Val158Met polymorphism. Executive control functioning was measured using the Intra-Extra Dimensional Set Shift (IED)...

BACKGROUND: Alcohol use disorders adversely affect individual and societal health. These disorders are a chronic brain disease, and protective factors against relapse should be studied. Prefrontal cortex (PFC) dysfunction is evident in alcohol use disorders, and research that explores recovery of the PFC in alcohol use disorders is needed, specifically in regard to how psychological and behavioral factors can augment medicalized treatments and protect against relapse. For example, hope or a belief that recovery is possible is an important cognitive construct-thought to precede behavioral action-that has been associated with relapse...

This study aimed to determine: i) the correlation between objective and subjective cognition, ii) the correlates of objective and subjective cognition and iii) the predictors of discrepancy between objective and subjective cognition. Participants were non-elderly patients with major depressive disorder (MDD). We assessed subjective cognition using the Perceived Deficit Questionnaire for Depression (PDQ-D) and objective cognition using Face I and Face II tests of the Wechsler Memory Scale, 3rd edition and Digit Span and Matrix Reasoning tests of the Wechsler Intelligence Scale for Adults, 3rd edition...

BACKGROUND: Mutations in the nuclear-encoded mitochondrial DNA polymerase gamma (POLG) can result in a wide spectrum of neurological deficits. A common presentation is progressive ataxia (POLG-A) which includes impaired speech and swallowing. The nature, severity and impact of these deficits in POLG-A is not known. A comprehensive quantitative and qualitative characterization of dysarthria and dysphagia in this recurrent ataxia disorder will assist in diagnostics, provide insights into the underlying pathology, and establish the foundation for future therapy trials...

BACKGROUND: An overlap of clinical symptoms between major depressive disorder (MDD) and social anxiety disorder (SAD) suggests that the two disorders exhibit similar brain mechanisms. However, few studies have directly compared the brain structures of the two disorders. The aim of this study was to assess the gray matter volume (GMV) and cortical thickness alterations between non-comorbid medication-naive MDD patients and SAD patients. METHODS: High-resolution T1-weighted images were acquired from 37 non-comorbid MDD patients, 24 non-comorbid SAD patients and 41 healthy controls (HCs)...

Brain dysfunction, especially cognitive impairment, is one of the main complications in Alzheimer's disease (AD), which threatens the health of 46.8 million people worldwide. At present, the pathogenesis of cognitive dysfunction is only partially understood, and effective therapies for memory loss in AD remain elusive. Tetramethylpyrazine (TMP) is one of the major bioactive compounds purified from Chuanxiong, a Chinese herb used for the treatment of neurovascular and cardiovascular diseases. The neuroprotective properties of TMP are evident in some neurodegenerative diseases, including Parkinson's disease...

Background: the diagnosis of cerebral small vessel disease, a leading cause of vascular dementia (VaD), relies solely on neuroimaging studies. Circulating microRNAs (miRNAs) have been proposed as diagnostic biomarkers in various disorders. Our aim was to identify differentially expressed, circulating miRNAs in small vessel VaD which could serve as diagnostic biomarkers for this disease. Method: we performed plasma miRNA profiling by quantitative polymerase chain reaction (qPCR) array in small vessel VaD patients and age- and gender-matched, cognitively normal and healthy controls...

Huntington's disease (HD) is an inherited, dominant neurodegenerative disorder caused by an abnormal expansion of CAG triplets in the huntingtin gene (htt). Despite extensive efforts to modify the progression of HD thus far only symptomatic treatment is available. Recent work suggests that treating invertebrate and mice HD models with metformin, a well-known AMPK activator which is used worldwide to treat type 2-diabetes, reduces mutant huntingtin from cells and alleviates many of the phenotypes associated to HD...

Behavioral variant frontotemporal dementia, the most common form of frontotemporal dementia, is characterized by executive dysfunction and changes in personality and behavior, sometimes with associated psychiatric disorders. We report a man who suddenly developed a gambling disorder when he was 55 years old. A year later he developed personality changes of agitation, euphoria, and disinhibition, along with binge eating and dysthymia. He did not improve on paroxetine 40 mg/day. Two years after the onset of his symptoms, he came to our clinic for evaluation...

PURPOSE OF REVIEW: To provide an overview of a selection of largely neglected psychological risk factors for nonadherence, and to offer new approaches to improve medication adherence. RECENT FINDINGS: Current adherence research and intervention programs focus on a few risk factors for nonadherence, such as complexity of the drug regimen. In addition, other important risk factors of nonadherence are neglected or insufficiently addressed. There is good evidence for the significant role of the quality of the patient-healthcare provider relationship...

BACKGROUND: The comorbidity of depression, posttraumatic stress disorder (PTSD), and substance use disorder (SUD) is common among veterans. Some research indicates that poor expectancies for negative mood regulation (NMR) may be associated with depression, trauma symptoms, and substance abuse. However, little is known about whether NMR expectancies can be changed through psychotherapy and if so, whether changes in NMR expectancies are related to changes in depression, PTSD, and SUD. METHODS: Therefore, this study examined 1) whether negative mood regulation (NMR) expectancies correlate with depression, PTSD, and SUD symptoms, 2) whether NMR expectancies improve after group integrated cognitive behavioral therapy (ICBT) and 3) whether these changes were associated with improvements in depression, PTSD, and SUD symptoms in a sample of 123 veterans (89% male, 64% non-Hispanic Caucasian) recruited from a Department of Veteran Affairs (VA) Healthcare System...

Prolyl oligopeptidase (POP), also called prolyl endopeptidase, is a cytosolic enzyme investigated by several research groups. It has been proposed to play an important role in physiological processes such as modulation of the levels of several neuronal peptides and hormones containing a proline residue. Due to its proteolytic activity and physiological role in cell signaling pathways, inhibition of POP offers an emerging approach for the treatment of Alzheimer's and Parkinson's diseases as well as other diseases related to cognitive impairment...

Pediatric feeding disorders affect up to 5% of children, causing severe food intake problems that can result in serious medical and developmental outcomes. Behavioral intervention (BI) is effective in extinguishing feeding aversions, and also expert-dependent, time/labor-intensive and not well understood at a neurobiological level. Here we first conducted a double-blind, placebo-controlled trial comparing BI with BI plus d-cycloserine (DCS). DCS is a partial N-methyl-d-aspartate (NMDA) receptor agonist shown to augment extinction therapies in multiple anxiety disorders...

Incidental memory may reflect a form of learning in everyday life, although it is not consistently evaluated during standard neuropsychological evaluations. Further validation of a recently created measure of verbal Incidental Learning (IL) from the Wechsler Adult Intelligence Scale-IV is necessary to understand the utility of such a measure in clinical settings. Sixty-eight adults aged 50 to 89 were recruited from a Cognitive Disorders Clinic while receiving a standard neuropsychological assessment, along with two additional measures of IL...
