Aura and Head pain: relationship and gaps in the translational models.

Migraine is a complex brain disorder and initiating events for acute attacks still remain unclear. It seems difficult to explain the development of migraine headache with one mechanism and/or a single anatomical location. Cortical spreading depression (CSD) is recognized as the biological substrate of migraine aura and experimental animal studies have provided mechanisms that possibly link CSD to the activation of trigeminal neurons mediating lateralized head pain.

Widespread higher fractional anisotropy associates to better cognitive functions in individuals at ultra-high risk for psychosis.

In schizophrenia patients, cognitive functions appear linked to widespread alterations in cerebral white matter microstructure. Here we examine patterns of associations between regional white matter and cognitive functions in individuals at ultra-high risk for psychosis. One hundred and sixteen individuals at ultra-high risk for psychosis and 49 matched healthy controls underwent 3 T magnetic resonance diffusion-weighted imaging and cognitive assessments.

HNRNPDL-related muscular dystrophy: expanding the clinical, morphological and MRI phenotypes.

Autosomal dominant limb girdle muscular dystrophy D3 HNRNPDL-related is a rare dominant myopathy caused by mutations in HNRNPDL. Only three unrelated families have been described worldwide, a Brazilian and a Chinese carrying the mutation c.1132G>A p.

Nfat5 is involved in the hyperosmotic regulation of Tmem184b: a putative modulator of ibuprofen transport in renal MDCK I cells.

Nuclear factor of activated T cells 5 (NFAT5) is a transcription factor involved in the regulation of several genes involved in the response to extracellular hyperosmolality. Recently, the uptake of ibuprofen by an as yet unknown carrier was suggested in Madin-Darby canine kidney (MDCK) I cells exposed to hyperosmolality. We therefore speculated that Nfat5 could be involved in the regulation of this ibuprofen carrier.

Brain network disintegration as a final common pathway for delirium: a systematic review and qualitative meta-analysis.

Delirium is an acute neuropsychiatric syndrome characterized by altered levels of attention and awareness with cognitive deficits. It is most prevalent in elderly hospitalized patients and related to poor outcomes. Predisposing risk factors, such as older age, determine the baseline vulnerability for delirium, while precipitating factors, such as use of sedatives, trigger the syndrome.

Neuroimaging clues of migraine aura.

While migraine headaches can be provoked, or predicted by the presence of an aura or premonitory symptoms, the prediction or elicitation of the aura itself is more problematic. Therefore, imaging studies directly examining the aura phenomenon are sparse. There are however interictal imaging studies that can shed light on the pathophysiology of the migraine with aura (MWA) cascade.

Brain-derived neurotrophic factor DNA methylation mediates the association between neighborhood disadvantage and adolescent brain structure.

Prior research indicates that socioeconomic disadvantage is associated with prefrontal cortical (PFC) development in childhood and adolescence, however the mechanisms of this link are unclear. This study investigated whether DNA methylation of the brain-derived neurotrophic factor (BDNF, which plays a key role in synaptic plasticity), mediated the association between neighborhood disadvantage and thickness of the PFC in adolescents. Neighborhood disadvantage was measured in 33 adolescents aged 12-13 years using the Socio-Economic Indexes for Areas.

Behavioral and cognitive animal models in headache research.

Animal models have provided a growing body of information about the pathophysiology of headaches and novel therapeutic targets. In recent years, experiments in awake animals have gained attention as more relevant headache models. Pain can be assessed in animals using behavioral alterations, which includes sensory-discriminative, affective-emotional and cognitive aspects.

Cognitive dysfunction and migraine.

Cognitive dysfunction has recently gained attention as a significant problem among migraine sufferers. All of the clinical studies show poor cognitive performance during migraine attacks, though, the interictal data are conflicting. Migraineurs show impaired cognitive function interictally in most of the clinic-based studies.

ESSENCE-Q: Slavic language versions for developmental screening in young children.

Purpose: The Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations - Questionnaire (ESSENCE-Q) was developed as a brief screener to identify children with developmental concerns who might have neurodevelopmental disorders (NDDs). This study aimed to translate the ESSENCE-Q into south Slavic languages, namely, Bosnian, Bulgarian, Croatian, Macedonian, Montenegrin, Serbian, and Slovenian, and to evaluate its psychometric properties for screening purposes in clinical settings.

Patients And Methods: In the study, the ESSENCE-Q was completed for 251 "typically developing" children and 200 children with 1 or more diagnosed NDDs, all aged 1-6 years.

Effect of visual stimuli of pain on empathy brain network in people with and without Autism Spectrum Disorder.

The extent to which affective empathy is impaired in Autism Spectrum Disorder (ASD) remains unclear, as some-but not all-previous neuroimaging studies investigating empathy for pain in ASD have shown similar activation levels to those of neurotypicals individuals. These inconsistent results could be due to the use of different empathy-eliciting stimuli. While some studies used pictures of faces exhibiting a painful expression, others used pictures of limbs in painful situations.

Influence of anxiety and alexithymia on brain activations associated with the perception of others' pain in autism.

The circumstances under which empathy is altered in ASD remain unclear, as previous studies did not systematically find differences in brain activation between ASD and controls in empathy-eliciting paradigms, and did not always monitor whether differences were primarily due to ASD "per se", or to conditions overlapping with ASD, such as alexithymia and anxiety. Here, we collected fMRI data from 47 participants (22 ASD) viewing pictures depicting hands and feet of unknown others in painful, disgusting, or neutral situations. We computed brain activity for painful and disgusting stimuli (vs.

Methodological factors as a potential source of discordance between self-report and behavioral measures of impulsivity and related constructs.

There is a consistent but poorly understood finding that self-report and behavioral measures of impulsivity are weakly correlated or uncorrelated. There are many possible explanations for this observation, including differences in how these instruments are administered and scored. The present study examined the utility of alternative scoring algorithms for self-report measures that aim to identify participants' peak impulsivity (or self-control), informed by estimates of item difficulty from Item Response Theory (IRT) analyses.

AbobotulinumtoxinA Efficacy and Safety in Children With Equinus Foot Previously Treated With Botulinum Toxin.

Background: The effects of botulinum toxin are transient, and repeat injections are required in children with lower-limb spasticity. However, the efficacy of botulinum toxin in patients who have received previous injections has remained largely unexplored.

Methods: We present subgroup analyses of a phase III study conducted in ambulatory children (aged two to 17) with spastic equinus foot.

Dietary dopamine depletion blunts reward network sensitivity to face trustworthiness.

Research demonstrating responsiveness of the neural reward network to face trustworthiness has not assessed whether the effects are mediated by dopaminergic function. We filled this gap in the literature by investigating whether dietary dopamine depletion would blunt the sensitivity of neural activation to faces varying in trustworthiness across reward regions as well as the sensitivity of behavioral responses to those faces. As prolactin release is negatively regulated by dopamine, peripheral prolactin levels confirmed the efficacy of our manipulation.

Bumetanide for autism: more eye contact, less amygdala activation.

We recently showed that constraining eye contact leads to exaggerated increase of amygdala activation in autism. Here, in a proof of concept pilot study, we demonstrate that administration of bumetanide (a NKCC1 chloride importer antagonist that restores GABAergic inhibition) normalizes the level of amygdala activation during constrained eye contact with dynamic emotional face stimuli in autism. In addition, eye-tracking data reveal that bumetanide administration increases the time spent in spontaneous eye gaze during in a free-viewing mode of the same face stimuli.

Struggling with one's own parenting after an upbringing with substance abusing parents.

Aim: To add to our knowledge concerning the key elements involved in the individual's experience of growing up with substance abusing parents and the resulting challenges this involved for their own parenthood.

Methods: In-depth interviews were conducted with 19 parents who had participated in a mental health intervention programme. All had experienced substance abusing parents in their family of origin.

The effect of high-dose atorvastatin on neural activity and cognitive function.

Background: Functional magnetic resonance imaging (fMRI) has not been used to assess the effects of statins on the brain. We assessed the effect of statins on cognition using standard neuropsychological assessments and brain neural activation with fMRI on two tasks.

Methods: Healthy statin-naïve men and women (48±15 years) were randomized to 80 mg/day atorvastatin (n=66; 27 men) or placebo (n=84; 48 men) for 6 months.

Relative short-term efficacy and acceptability of agomelatine versus vortioxetine in adult patients suffering from major depressive disorder.

Agomelatine and vortioxetine are antidepressants with different mechanisms of action compared to other pharmaceutical treatment options. The objective of this present analysis is to determine the relative efficacy and acceptability of agomelatine (25-50 mg) compared to vortioxetine (10-15-20 mg) in adult patients with major depressive disorder. We performed an adjusted indirect comparison using placebo as a common control.

Long-term behavioural outcomes after paediatric convulsive status epilepticus: a population-based cohort study.

Aim: To describe behavioural and psychiatric outcomes of children within 10 years of convulsive status epilepticus (CSE).

Method: Children originally identified by the population-based North London Convulsive Status Epilepticus in Childhood Surveillance Study were followed-up between July 2009 and February 2013. They were grouped into epilepsy- and non-epilepsy-related CSE, and compared with population norms and healthy controls using the Strengths and Difficulties Questionnaire; the Autism Spectrum Screening Questionnaire; and the Swanson, Nolan, and Pelham questionnaire.

Korsakoff's syndrome: a critical review.

In this review, we present a survey on Korsakoff's syndrome (KS), a residual syndrome in patients who suffered from a Wernicke encephalopathy (WE) that is predominantly characterized by global amnesia, and in more severe cases also by cognitive and behavioral dysfunction. We describe the history of KS and its definition, its epidemiology, and the lack of consensus criteria for its diagnosis. The cognitive and behavioral symptoms of KS, which include anterograde and retrograde amnesia, executive dysfunction, confabulation, apathy, as well as affective and social-cognitive impairments, are discussed.
