Hypochondriasis (HYPO), an obsessive-compulsive spectrum disorder, is frequent in patients with schizophrenia (SCH) (20%), especially among those treated with clozapine (36.7%). Treatment options for OCS/OCD in patients under clozapine (CLZ) include combining clozapine with amisulpride/aripiprazole or a mood stabilizer, augmenting clozapine with a serotoninergic reuptake inhibitor, adding cognitive behavioural therapy, and gradually reducing dosage. No treatments have been proposed for HYPO in patients using clozapine so we examine these options in 2 cases and report the results...

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...

Background: Accumulating evidence suggests that neuroinflammation plays a critical role in early brain injury after subarachnoid hemorrhage (SAH). Pannexin-1 channels, as a member of gap junction proteins located on the plasma membrane, releases ATP, ions, second messengers, neurotransmitters, and molecules up to 1 kD into the extracellular space, when activated. Previous studies identified that the opening of Pannexin-1 channels is essential for cellular migration, apoptosis and especially inflammation, but its effects on inflammatory response in SAH model have not been explored yet...

Mϕs of patients with Alzheimer's disease and mild cognitive impairment (MCI) are defective in amyloid-β1-42 (Aβ) phagocytosis and have low resistance to apoptosis by Aβ. ω-3 in vitro and in vivo and the ω-3 mediator, resolvin D1, in vitro increase Aβ phagocytosis by Mϕs of patients with MCI. We have investigated the unfolded protein response (UPR) to endoplasmic reticulum (ER) stress by Mϕs in a longitudinal study of fish-derived, ω-3-supplemented patients with MCI. Patients in the apolipoprotein E (ApoE)e3/e3 subgroup over time exhibited an increase of protein kinase RNA-like ER kinase (PERK) expression, Aβ phagocytosis, intermediate M1-M2 Mϕ type, and a Mini-Mental State Examination (MMSE) rate of change of +1...

Imbalance in neural excitation and inhibition is associated with behavioral dysfunction in individuals with schizophrenia and at risk for this illness. We examined whether targeting increased neural activity with the antiepileptic agent, levetiracetam, would benefit memory performance in a preclinical model of schizophrenia that has been shown to exhibit hyperactivity in the hippocampus. Adult rats exposed to ketamine subchronically during late adolescence showed impaired hippocampal-dependent memory performance...

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...

Treatment of patients with Treatment-resistant Schizophrenia (TRS), who fail to respond to multiple antipsychotic trials, including clozapine (CLZ), is challenging. Several alternative strategies are reported in studies, one of which includes augmenting antipsychotics (AP) with Electroconvulsive therapy (ECT). We discuss a case of an acutely psychotic patient with TRS who responded effectively and sustained remission to this strategy which was ECT combined with two AP, CLZ and aripiprazole. Notable improvement in clinical and cognitive outcomes was seen with just five right unilateral ECT sessions, CLZ titrated up to 62...

BACKGROUND: Exposure therapy is an established learning-based intervention for the treatment of anxiety disorders with an average response rate of nearly 50%, leaving room for improvement. Emerging strategies to enhance exposure therapy in humans and fear extinction retention in animal models are primarily pharmacological. These approaches are limited as many patients report preferring non-pharmacological approaches in therapy. With general cognitive enhancement effects, exercise has emerged as a plausible non-pharmacological augmentation strategy...

Panic disorder is a common mental disease with high psychiatric comorbidity. It is considered that a combination of genetic predisposition and a special psychic vulnerability plays a key role in the occurrence of panic disorder. Clinically proven efficacy in the treatment of panic disorder have benzodiazepines, tricyclic antidepressants, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors and selective serotonin and norepinephrine reuptake inhibitors; antidepressants from other pharmaceutical groups are also used...

Children's and parents' attachment patterns have been linked with the presence of pediatric anxiety disorders. The present study examined the role of attachment in predicting cognitive behavior therapy (CBT) treatment outcomes. A total of 69 children aged 7-13 years were assessed using a semi-structured interview, and treated with CBT. Differences between responders and nonresponders with regard to pretreatment characteristics were explored, and the predictive power of factors significantly different between groups was assessed using binominal logistic regression...

Purpose: Augmentative and alternative communication (AAC) promotes communicative participation and language development for young children with complex communication needs. However, the motor, linguistic, and cognitive demands of many AAC technologies restrict young children's operational use of and influence over these technologies. The purpose of the current study is to better understand young children's participation in programming vocabulary "just in time" on an AAC application with minimized demands...

Genetic rescue, outcrossing with individuals from a related population, is used to augment genetic diversity in populations threatened by severe inbreeding and extinction. The endangered Norwegian Lundehund dog underwent at least two severe bottlenecks in the 1940s and 1960s that each left only five inbred dogs, and the approximately 1500 dogs remaining world-wide today appear to descend from only two individuals. The Lundehund has a high prevalence of a gastrointestinal disease, to which all remaining dogs may be predisposed...

REVIEW
Adam B Weinberger, Adam E Green, Evangelia G Chrysikou
Creative cognition is frequently described as involving two primary processes, idea generation and idea selection. A growing body of research has used transcranial direct current stimulation (tDCS) to examine the neural mechanisms implicated in each of these processes. This literature has yielded a diverse set of findings that vary depending on the location and type (anodal, cathodal, or both) of electrical stimulation employed, as well as the task's reliance on idea generation or idea selection. As a result, understanding the interactions between stimulation site, polarity and task demands is required to evaluate the potential of tDCS to enhance creative performance...

Physiological effects of different types, of continuous and interval aerobic training, have been largely described and studied in the adult man. It was previously indicated that interval training plays an important role in maximizing both peripheral muscle and central cardiorespiratory adaptations, permitting significant functional improvement even in healthy sedentary subjects. Since the outcome of different aerobic training trials on cognitive processes had never been evaluated, we compared, on an experimental mouse model, the effects of four training exercise protocols, named respectively C100, I100, C50 and I50 depending on the volume and on the type of training proposed, continuous or interval method...

Nutritional ketosis may enhance cerebral energy metabolism and has received increased interest as a way to improve or preserve performance and resilience. Most studies to date have focused on metabolic or neurological disorders while anecdotal evidence suggests that ketosis may enhance performance in the absence of underlying dysfunction. Moreover, decreased availability of glucose in the brain following stressful events is associated with impaired cognition, suggesting the need for more efficient energy sources...

Studies have shown that the removal of the cholinergic innervation to the hippocampus induces dysfunction of the hypothalamic-pituitary-adrenocortical axis and decreases the number of glucocorticoid receptors (GRs). Subsequent studies have revealed that the loss of cholinergic input to the hippocampus reduces the expression of GRs and activates nuclear factor-kappa B (NF-κB) signaling through interactions with the cytoplasmic catalytic subunit of protein kinase A (PKAc). We examined the effects of chronic stress on cognitive status and GR-PKAc-NF-κB signaling in rats with a loss of cholinergic input to the hippocampus and cortex...

OBJECTIVE: Several single-center studies have found raloxifene, an estrogen agonist, to be effective in ameliorating symptoms of schizophrenia in stable patients as augmentation of antipsychotics. This multicenter study assessed whether raloxifene plus antipsychotic treatment, in comparison to placebo plus antipsychotics, improves symptoms or cognition in severely ill decompensated schizophrenia patients. METHODS: In this 16-week, double-blind, randomized, placebo-controlled study, 200 severely ill, decompensated postmenopausal women who met DSM-IV-TR criteria for schizophrenia or schizoaffective disorder were recruited from January 2011 to December 2012 and were randomized to receive either raloxifene 120 mg/d plus antipsychotics or placebo plus antipsychotics...
