: Background: Cognitive dysfunction is a core transdiagnostic domain of Major Depressive Disorder (MDD) and is a principal determinant of functional recovery. However, it has been insufficiently targeted within the current therapeutic framework for MDD. OBJECTIVE: To highlight these unmet cognitive needs in MDD. METHODS: An article search was conducted using PubMed from inception to November 2016: Major Depressive Disorder (and/or variant) was cross-referenced with the following terms: antidepressants, augmentation, cognition, cognitive deficits, cognitive dysfunction, functional outcomes, mechanism of action, and treatment...

BACKGROUND: Computerized cognitive behaviour therapy (CCBT) programs can provide a useful self-help approach to the treatment of psychological problems. Previous studies have shown that CCBT has moderate effects on depression, insomnia, and anxiety. The present study investigated whether a supplement drink that includes L-carnosine enhances the effect of CCBT on psychological well-being. METHODS: Eighty-seven participants were randomly allocated to a control group, CCBT, or CCBT with supplement drink...

Suicide is the second leading cause of death among undergraduate students, with an annual rate of 7.5 per 100,000. Suicidal behavior (SB) is complex and heterogeneous, which might be explained by there being multiple etiologies of SB. Data-driven identification of distinct at-risk subgroups among undergraduates would bolster this argument. We conducted a latent class analysis (LCA) on survey data from a large convenience sample of undergraduates to identify subgroups, and validated the resulting latent class model on a sample of graduate students...

Acute exposure to light within the blue wavelengths has been shown to enhance alertness and vigilance, and lead to improved speed on reaction time tasks, possibly due to activation of the noradrenergic system. It remains unclear, however, whether the effects of blue light extend beyond simple alertness processes to also enhance other aspects of cognition, such as memory performance. The aim of this study was to investigate the effects of a thirty minute pulse of blue light versus placebo (amber light) exposure in healthy normally rested individuals in the morning during verbal memory consolidation (i...

Differential brain structural abnormalities between bipolar disorder (BD) and major depressive disorder (MDD) may reflect different pathological mechanisms underlying these two brain disorders. However, few studies have directly compared the brain structural properties, especially in white matter (WM) tracts, between BD and MDD. Using automated fiber-tract quantification (AFQ), we utilized diffusion tensor images (DTI) from 67 unmedicated depressed patients, including 31 BD and 36 MDD, and 45 healthy controls (HC) to create fractional anisotropy (FA) tract profiles along 20 major WM tracts...

Preclinical studies have demonstrated exercise improves various types of behaviours such as anxiety-like, depression-like, and cognition-like behaviours. However, these findings were largely conducted in studies utilising short-term exercise protocols, and the effects of lifetime exercise on these behaviours remain unknown. This study investigates the behavioural effects of lifetime exercise in normal healthy aging C57BL/6 mice over the adult lifespan. 12 week-old C57BL/6 mice were randomly assigned to voluntary wheel running or non-exercise (control) groups...

Electroconvulsive therapy (ECT) is an effective treatment for depression, but can have negative side effects including amnesia. The mechanisms of action underlying both the antidepressant and side effects of ECT are not well understood. An equivalent manipulation that is conducted in experimental animals is electroconvulsive seizure (ECS). Rodent studies have provided valuable insights into potential mechanisms underlying the antidepressant and side effects of ECT. However, relatively few studies have investigated the effects of ECS in animal models with a depression-relevant manipulation such as chronic stress...

The regulated transport of AMPA-type glutamate receptors (AMPARs) to the synaptic membrane is a key mechanism to determine the strength of excitatory synaptic transmission in the brain. In this work, we uncovered a new role for the microtubule-associated protein MAP1B, in modulating the access of AMPARs to the postsynaptic membrane. Using mice and rats of either sex, we show that MAP1B light chain (LC) accumulates in the somatodendritic compartment of hippocampal neurons, where it forms immobile complexes on microtubules that limit vesicular transport...

Arsenic exposure through drinking water can impair the learning and memory ability of children in China and other countries. Synaptic plasticity plays a key role in the process of learning and memory. Alterations in the expression of presynaptic and postsynaptic proteins can be used to evaluate synaptic plasticity, and further to evaluate impairment in learning and memory ability. Thereby, the aim of this study was to explore the mechanisms underlying arsenic neurotoxicity by focusing on alterations in the hippocampal synapses of mouse offspring induced by developmental arsenite exposure...

Neuroactive steroids (NASs) are naturally occurring steroids, which are synthesized centrally as de novo from cholesterol and are classified as pregnane, androstane, and sulfated neurosteroids (NSs). NASs modulate many processes via interacting with gamma-aminobutyric acid (GABA), N-methyl-d-aspartate, serotonin, voltage-gated calcium channels, voltage-dependent anion channels, α-adrenoreceptors, X-receptors of the liver, transient receptor potential channels, microtubule-associated protein 2, neurotrophin nerve growth factor, and σ1 receptors...

Fragile X syndrome (FXS) is a neurodevelopmental disorder caused by mutations in the FMR1 gene that inactivate expression of the gene product, the fragile X mental retardation 1 protein (FMRP). In this study, we used clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) technology to generate Fmr1 knockout (KO) rats by disruption of the fourth exon of the Fmr1 gene. Western blotting analysis confirmed that the FMRP was absent from the brains of the Fmr1 KO rats (Fmr1(exon4-KO) )...

Memory formation relies on experience-dependent changes in synaptic strength such as long-term potentiation (LTP) or long-term depression (LTD) of synaptic activity, that in turn depend on previous learning experiences through metaplasticity. Novelty detection is a particularly important cognitive stimulus in this respect, and mismatch novelty has been associated with the activation of the hippocampal CA1 area in human studies. A single exposure a new location of known objects in a familiar environment, a behavioural mismatch novelty paradigm, is known to favour the expression of LTD in hippocampal CA3 to CA1 synaptic transmission in vivo, through short-term metaplasticity...

Various studies reported beneficial effects of dehydroepiandrosterone (DHEA) and its sulphate (DHEAS), the neurosteroids involved in various brain functions, on synaptic plasticity, neuronal survival, memory, learning and behavior. This study aimed to investigate the behavioral profile of acute DHEA treatment by using active avoidance (AA) task, primarily predictive of the effects on the retrieval-based learning, and by applying forced swim test (FST), for assessment of antidepressant-like potential. Adult male Wistar rats received intraperitoneal injections of either DHEA (2, 10, 20mg/kg) or solvent, 30min prior to testing...

BACKGROUND: The placebo effect is usually studied in clinical settings for decreasing negative symptoms such as pain, depression and anxiety. There is interest in exploring the placebo effect also outside the clinic, for enhancing positive aspects of performance or cognition. Several studies indicate that placebo can enhance cognitive abilities including memory, implicit learning and general knowledge. Here, we ask whether placebo can enhance creativity, an important aspect of human cognition...

Sickness behaviors, adaptive responses to infections, include lethargy, depression, reduced eating and grooming, and concentration problems resulting from interactions between the immune and neuroendocrine systems. Detecting these responses is especially critical in the elderly, as the infections that cause them can lead to cognitive impairment. While deficits in spatial learning, a hippocampal-dependent form of learning, are part of the sickness response, directional heading errors (DHEs; an indicator of spatial-learning deficits) and their time trajectories need further examination...

A dynamic treatment regime is a sequence of decision rules, each of which recommends treatment based on features of patient medical history such as past treatments and outcomes. Existing methods for estimating optimal dynamic treatment regimes from data optimize the mean of a response variable. However, the mean may not always be the most appropriate summary of performance. We derive estimators of decision rules for optimizing probabilities and quantiles computed with respect to the response distribution for two-stage, binary treatment settings...

REVIEW
Ruth E Carmichael, Jeremy M Henley
One of the most interesting features of Arc-dependent synaptic plasticity is how multiple types of synaptic activity can converge to alter Arc transcription and then diverge to induce different plasticity outcomes, ranging from AMPA receptor internalisation that promotes long-term depression (LTD), to actin stabilisation that promotes long-term potentiation (LTP). This diversity suggests that there must be numerous levels of control to ensure the temporal profile, abundance, localisation and function of Arc are appropriately regulated to effect learning and memory in the correct contexts...

Cognitive impairment (CI) is common and debilitating in patients with multiple sclerosis. However, little is known about how different disease courses affect CI, impeding prognosis and disease management. Here, we contrasted the magnitude and profile of CI measured with standardized neuropsychological tests in patients with primary progressive multiple sclerosis (PPMS) against relapsing-remitting multiple sclerosis (RRMS) while considering potentially confounding demographic and clinical differences. Systematic literature review and meta-analysis was performed finding 47 eligible studies (N=4460 patients)...

Jessica Santana, María-Paz Marzolo
Reelin is a large extracellular matrix protein with relevant roles in mammalian central nervous system including neurogenesis, neuronal polarization and migration during development; and synaptic plasticity with its implications in learning and memory, in the adult. Dysfunctions in reelin signaling are associated with brain lamination defects such as lissencephaly, but also with neuropsychiatric diseases like autism, schizophrenia and depression as well with neurodegeneration. Reelin signaling involves a core pathway that activates upon reelin binding to its receptors, particularly ApoER2 (apolipoprotein E receptor 2)/LRP8 (low-density lipoprotein receptor-related protein 8) and very low-density lipoprotein receptor, followed by Src/Fyn-mediated phosphorylation of the adaptor protein Dab1 (Disabled-1)...
