BACKGROUND: Mental imagery has a more powerful impact on our emotions than thinking in words about the same material. Treating intrusive images with imagery rescripting (IR) has been reported for various disorders, including post-traumatic stress disorder, social anxiety disorder, and bipolar disorder. There has been less research about IR as a major depressive disorder (MDD). AIMS: We examined whether IR without focusing on early traumatic memories is effective in MDD...

We report on the magnetic field control of a bipolar resistive switching in Ag/TiO2/FTO based resistive random access memory device through I-V characteristics. Essentially, in the presence of magnetic field and in the low resistance state, an abrupt change in the resistance of the device demands higher voltage, hinting that residual Lorentz force plays a significant role in controlling the resistance state. Endurance characteristics of the device infer that there is no degradation of the device even after repeated cycling, which ensures that the switching of resistance between 'off' and 'on' states is reproducible, reversible and controllable...

Adult-onset adrenoleukodystrophy is a rare x-linked inborn error of metabolism occurring predominantly in males with onset in early 30s. Here, we report a 34-year-old male with first signs of disease in early 20s manifesting as a pure psychiatric disorder. Prior to onset of neurological symptoms, this patient demonstrated a schizophrenia and bipolar-like presentation. The disease progressed over the next 10-13 years and his memory and motor problems became evident around the age of 33 years. Subsequently, diagnostic testing showed the typical magnetic resonance imaging and lab findings for adult-onset adrenoleukodystrophy...

Prominent cognitive deficits have been documented in bipolar disorder, and multiple studies suggest that these deficits can be observed among non-affected first-degree relatives of those with bipolar disorder. Although there is variability in the degree of cognitive deficits, these deficits are robustly relevant for functional outcomes. A separate literature documents clear difficulties in emotionality, emotion regulation, and emotion-relevant impulsivity within bipolar disorder, and demonstrates that these emotion-relevant variables are also central to outcome...

OBJECTIVE: Anticholinergic medications are prescribed to treat extrapyramidal side effects (EPS) associated with antipsychotics. Anticholinergic medications cause several side effects and can often be withdrawn during the maintenance phase of antipsychotic treatment without EPS reemergence. The purpose of this quality improvement (QI) project was to reduce anticholinergic medication burden and improve quality of life in patients with severe mental illness. METHODS: Patients with DSM-IV-TR-diagnosed schizophrenia, schizoaffective disorder, and bipolar disorders in an outpatient psychiatric clinic who were prescribed benztropine were identified, screened for anticholinergic side effects by the treating psychiatrist, and referred to an on-site clinical pharmacist for a comprehensive medication review...

Bi0.8Pr0.2Fe0.95Mn0.05O₃/Bi3.96Gd0.04Ti2.95W0.05O12 (BPFMO/BGTWO) bilayer thin films with Multiferroic/Ferroelectric (MF/FE) structures were deposited onto Pt(111)/Ti/SiO₂/Si(100) substrates by using the sol-gel method with rapid thermal annealing. The BPFMO/BGTWO thin films exhibited well-saturated ferromagnetic and ferroelectric hysteresis loops because of the electro-magnetic coupling induced by the MF/FE structure. The remnant magnetization (2Mr) and remnant polarization (2Pr) were 4.6 emu/cm³ and 62 μC/cm², respectively...

There is a lack of consensual tools for evaluating the cognitive side-effects in patients with depression who are treated with electroconvulsive therapy (ECT). The objective of this study was to evaluate the usefulness of the Montreal Cognitive Assessment (MoCA) and of the Mini Mental State Examination (MMSE) to monitor cognitive changes in patients with depression receiving ECT. Cognitive functioning was assessed prospectively in 48 patients with unipolar or bipolar depression before and after an ECT course...

OBJECTIVES: Bipolar disorder (BD) carries the greatest risk of death by suicide of all psychiatric conditions as 25%-50% of those with BD will make one or more suicide attempt, and about 15% will intentionally end their lives. Among young adults with BD, substance misuse, medication non-adherence, age at onset, and comorbid psychiatric conditions each predict self-harm. It is currently unclear if these same factors or others predict suicide ideation among older adults with BD. METHODS: We recruited a global sample of 220 older adults with BD over 19 days using socio-demographically targeted, social media advertising and online data collection (Mean = 58...

Amorphous KNbO3 (KN) film containing KN nanocrystals was grown on TiN/SiO2/Si substrate at 350(o)C. This KN film showed a dielectric constant (εr) and piezoelectric strain constant (d33) of 43 and 80 pm/V at 10 V, respectively, owing to the existence of KN nanocrystals. Piezoelectric nanogenerators (PNGs) were fabricated using KN films grown on the TiN/Polyimide/PET substrates. PNG fabricated with the KN film grown at 350(o)C showed an open-circuit output voltage of 2.5 V and a short-circuit current of 70 nA...

Resistively switching devices are promising candidates for the next generation of non-volatile data memories. Such devices are up to now fabricated mainly by means of top-down approaches that apply thin films sandwiched between electrodes. Recent works have demonstrated that resistive switching (RS) is also feasible on chemically synthesized nanoparticles (NPs) in the 50 nm range. Following this concept, we developed this approach further to the sub-10 nm range. In this work, we report RS of sub-10 nm TiO₂ NPs that were self-assembled into monolayers and transferred onto metallic substrates...

Improvement or at least control of variability is one of the key challenges for Redox based resistive switching memory technology. In this paper, we investigate the impact of a serial resistor as a voltage divider on the SET variability in Pt/Ta2O5/Ta/Pt nano crossbar devices. A partial RESET in a competing complementary switching (CS) mode is identified as a possible failure mechanism of bipolar switching SET in our devices. Due to a voltage divider effect, serial resistance value shows unequal impact on switching voltages of both modes which allows for a selective suppression of the CS mode...

There are conflicting findings about prospective memory (PM) performance in bipolar disorder. This meta-analysis systematically examined PM in patients with bipolar disorders. Articles were systematically searched in both English and Chinese databases, from their inception to Nov 15, 2016. Only case-control studies on PM in bipolar patients were included for analyses. The random effect model was used in all meta-analytic outcomes. Four studies (n = 390) comparing PM performance between patients with bipolar disorder (n = 208) and healthy controls (n = 182) were included...

BACKGROUND: Psychosis in bipolar I disorder (BDI) has been associated with increased cognitive dysfunction, which may relate to poorer functional outcomes. However, it is not known whether cognition differs between BDI patients with (BDP+) or without (BDP-) history of psychosis early in the disease course, or if it is impacted by the presence of mood congruent (MCP) versus incongruent (MIC) psychotic features. We compare cognition between these groups in BDI patients recently recovered from first episode of mania...

BackgroundThe relationship between residual depressive symptoms, cognition and functioning in patients with euthymic bipolar disorder is a subject of debate.AimsTo assess whether cognition mediates the association between residual depressive symptoms and functioning in patients with bipolar disorder who were euthymic.MethodWe included 241 adults with euthymic bipolar disorder in a multicentre cross-sectional study. We used a battery of tests to assess six cognition domains. A path analysis was then used to perform a mediation analysis of the relationship between residual depressive symptoms, cognitive components and functioning...

OBJECTIVE: Cognitive dysfunction is a core symptom dimension in bipolar disorder and a strong predictor of functional outcomes. Cognitive remediation (CR) produces moderate, durable effects on cognition in patients with schizophrenia; however, studies of CR in patients with bipolar disorder are sparse and findings have been mixed. Thus, the aim of this study was to evaluate the effects of CR versus active control in patients with bipolar disorder with psychosis. METHODS: Patients with a DSM-IV diagnosis of bipolar disorder with psychosis (n = 75) were randomized to a 70-hour computerized CR program or a dose-matched computer control using a parallel design with 1:1 allocation between July 2011 and November 2015...

BACKGROUND: Deep brain stimulation (DBS) of the human entorhinal area using 50 Hz pulses has revealed conflicting results regarding memory performance. Moreover, its impact on memory-related hippocampal potentials has not yet been investigated. METHODS: We recorded data from seven epilepsy patients implanted with depth electrodes in the entorhinal cortex, hippocampus, amygdala and parahippocampal cortex. Entorhinal DBS (bipolar, biphasic 50 Hz pulses, on- and off-cycles of 15 s) was applied with low amplitude (0...

INTRODUCTION: Bipolar disorder is associated with cognitive dysfunction in several domains. Medication effect is a potential confounder that can only be statistically controlled in many studies. The cognitive profile in bipolar disorder during remission on maintenance antipsychotics or mood stabilizers medication has not been compared before. METHODS: We compared the cognitive profile of bipolar disorder patients euthymic for 2 month or more on monotherapy with novel antipsychotics (AP) (n=16), lithium carbonate (Li) (n=25) or valproic acid (VPA; n=26)...

Nonpolar resistive switching (RS), a combination of bipolar and unipolar RS, is demonstrated for the first time in a single nanowire (NW) system. Exploiting Ag@TiO2 core-shell (CS) NWs synthesized by postgrowth shell formation, the switching mode is controlled by adjusting the current compliance effectively, tailoring the electrical polarity response. We demonstrate ON/OFF ratios of 10(5) and 10(7) for bipolar and unipolar modes, respectively. In the bipolar regime, retention times could be controlled up to 10(3) s, and in the unipolar mode, >10(6) s was recorded...
