INTRODUCTION: This study investigated the effects of a marine oil extract (PCSO-524®) on inattention, hyperactivity, mood and cognition in children and adolescents. PCSO-524® is a standardised lipid extract of the New Zealand green-lipped mussel and is an inflammatory modulator that inhibits the 5'-lipoxygenase and cyclooxygenase pathways and decreases concentrations of the pro-inflammatory arachidonic acid (AA). METHODS: PCSO-524® or a matched placebo was administered for 14 weeks to 144 participants (123 males/21 females; mean age 8...

Exposure to general anesthetic agents during development has been associated with neurotoxicity and long-term behavioral impairments in rodents and non-human primates. The phenotype of anesthetic-induced cognitive impairment has a robust learning and memory component, however less is known about other psychological domains. Data from retrospective human patient studies suggest that children undergoing multiple procedures requiring general anesthesia are at increased risk of attention deficit hyperactivity disorder...

The adolescent period in mammals is a critical period of brain maturation and thus represents a time of susceptibility to environmental insult, e.g. psychosocial stress and/or drugs of abuse, which may cause lasting impairments in brain function and behavior and even precipitate symptoms in at-risk individuals. One likely effect of these environmental insults is to increase oxidative stress in the developing adolescent brain. Indeed, there is increasing evidence that redox dysregulation plays an important role in the development of schizophrenia and other neuropsychiatric disorders and that GABA interneurons are particularly susceptible to alterations in oxidative stress...

A large body of evidence has been brought forward connecting developmental immune activation to abnormal fear and anxiety levels. Anxiety disorders have extremely high lifetime prevalence, yet susceptibility factors that contribute to their emergence are poorly understood. In this research we investigated whether an inflammatory insult early in life can alter the response to fear conditioning in adulthood. Fear learning and extinction are important and adaptive behaviors, mediated largely by the amygdala and its interconnectivity with cortico-limbic circuits...

Individuals with internet gaming disorder (IGD) often have impaired risky decision-making abilities, and IGD-related functional changes have been observed during neuroimaging studies of decision-making tasks. However, it is still unclear how feedback (outcomes of decision-making) affects the subsequent risky decision-making in individuals with IGD. In this study, twenty-four adolescents with IGD and 24 healthy controls (HCs) were recruited and underwent functional magnetic resonance imaging while performing the balloon analog risk task (BART) to evaluate the effects of prior outcomes on brain activity during subsequent risky decision-making in adolescents with IGD...

BACKGROUND: Schizophrenia (SZ) and bipolar disorder (BD) are considered neurobiological disorders which share some clinical, cognitive and neuroimaging characteristics. Studying child and adolescent offspring of patients diagnosed with bipolar disorder (BDoff) or schizophrenia (SZoff) is regarded as a reliable method for investigating early alterations and vulnerability factors for these disorders. This study compares the neuropsychological characteristics of SZoff, BDoff and a community control offspring group (CC) with the aim of examining shared and differential cognitive characteristics among groups...

BACKGROUND: Few studies have examined the link between air pollution exposure and behavioural problems and learning disorders during late childhood and adolescence. OBJECTIVES: To determine whether traffic-related air pollution exposure is associated with hyperactivity/inattention, dyslexia and dyscalculia up to age 15years using the German GINIplus and LISAplus birth cohorts (recruitment 1995-1999). METHODS: Hyperactivity/inattention was assessed using the German parent-completed (10years) and self-completed (15years) Strengths and Difficulties Questionnaire...

Neurofibromatosis Type 1 (NF1) is a progressive genetic disorder characterized by physical findings such as café-au-lait macules, Lisch nodules, and neurofibromas in addition to other medical complications. Learning and social problems are more prevalent among individuals affected with NF1. It has been reported that people with NF1 have lower self-esteem (SE) when compared to the general population. Additionally, a study published over 20 years ago found that overall knowledge of NF1 was lacking in individuals affected with the condition...

OBJECTIVE: To assess the functioning of mesolimbic and fronto-striatal areas involved in reward-based spatial learning in teenaged girls with bulimia nervosa (BN) that might be involved in the development and maintenance of maladaptive behaviors characteristic of the disorder. METHOD: We compared functional magnetic resonance imaging blood oxygen level-dependent response in 27 adolescent girls with BN to that of 27 healthy, age-matched control participants during a reward-based learning task that required learning to use extra-maze cues to navigate a virtual 8-arm radial maze to find hidden rewards...

The orphan nuclear receptor Tlx (Nr2e1) is a key regulator of both embryonic and adult hippocampal neurogenesis. Several different mouse models have been developed which target Tlx in vivo including spontaneous deletion models (from birth) and targeted and conditional knockouts. Although some conflicting findings have been reported, for the most part studies have demonstrated that Tlx is important in regulating the processes that underlie neurogenesis, spatial learning, anxiety-like behaviour and interestingly, aggression...

A number of chronic disease conditions tend to cluster in families with an increased risk in first-degree relatives, but also an increased risk in second-degree relatives. This fact is most often referred to as the heritability (heredity) of these diseases and explained by the influence of genetic factors, or shared environment, even if the more specific details or mechanism leading to disease are not known. New methods have to be explored in screening studies and register linkage studies to define and measure consequences of a positive family history of disease...

BACKGROUND: Bleeding disorders (BD) occur in up to 50% of adolescents with heavy menstrual bleeding (HMB). This presents unique challenges to healthcare providers given the complexity of treating the condition and such complexity can result in difficulty with patients understanding basic information about their condition, limit communication with medical providers, and patient compliance. SPECIFIC AIMS: To use an electronic approach to enhance patient compliance with medications used to treat their HMB...

Using a sample of 228 females with and without childhood attention-deficit/hyperactivity disorder followed prospectively across 16 years, we measured childhood neurocognitive vulnerability via executive dysfunction using teacher-reported cognitive and learning problems. We then ascertained relations between dimensionally measured internalizing and externalizing psychopathology during adulthood and showed that childhood neurocognitive vulnerability reliably predicted such associated psychopathology. We identified six serial mediation pathways from childhood neurocognitive vulnerability to adult psychopathology through three early- and late-adolescent domains: individual (self-control and delay of gratification), peer (rejection/conflict and acceptance/friendship), and school (academic performance and school failure)...

Prenatal viral infection has been identified as a potential risk factor for the development of neurodevelopmental disorders such as schizophrenia and autism. Additionally, dysfunction in gamma-aminobutyric acid, Reelin, and fragile X mental retardation protein (FMRP)-metabotropic glutamate receptor 5 signaling systems has also been demonstrated in these two disorders. In the current report, we have characterized the developmental profiles of selected markers for these systems in cerebella of mice born to pregnant mice infected with human influenza (H1N1) virus on embryonic day 16 or sham-infected controls using SDS-PAGE and Western blotting techniques and evaluated the presence of abnormalities in the above-mentioned markers during brain development...

Brain-derived neurotrophic factor (BDNF) is a growth factor that is dynamically expressed in the brain across postnatal development, regulating neuronal differentiation and synaptic plasticity. The neurotrophic hypothesis of psychiatric mood disorders postulates that in the adult brain, decreased BDNF levels leads to altered neural plasticity, contributing to disease. Although BDNF has been established as a key factor regulating the critical period plasticity in the developing visual system, it has recently been shown to also play a role in fear circuitry maturation, which has implications for the emergence of fear-related mood disorders...

Many patients who visit a centre for hereditary metabolic diseases remarkably also suffer from a child psychiatric disorder. Those child psychiatric disorders may be the first sign or manifestation of an underlying metabolic disorder. Lack of knowledge of metabolic disorders in child psychiatry may lead to diagnoses being missed. Patients therefore are also at risk for not accessing efficacious treatment and proper counselling. To search the literature for the co-occurrence of child psychiatric disorders, such as ADHD, autism, psychosis, learning disorders and eating disorders and metabolic disorders...
