Efavirenz is among the preferred antiretroviral drugs for HIV-infected children. Increasing evidence shows that central nervous system side-effects in adults are more common than previously thought. Still, reliable data in children are lacking. As HIV-infected children nowadays have a prospect of reaching adulthood, there is an urgent need to identify potential long-term central nervous system side-effects, interfering with neurodevelopment and psychosocial maturation. Using validated tools, we assessed (1) competence (social/activities/school) and psychopathology (internalizing/externalizing problems), (2) cognitive performance (intelligence and working memory), and (3) adherence in Tanzanian children on an efavirenz or non-efavirenz based regimen In this cross-sectional observational study the investigators will examine neuropsychiatric and neurocognitive functioning in 126 children (aged 6-11 years) on long-term combination antiretroviral therapy (cART) with or without efavirenz.
This study evaluates the effect of using comprehensive geriatric assessment in combination with case conferences on the prevalence of neuropsychiatric symptoms (also known as behavioral and psychological symptoms of dementia) in Norwegian nursing homes
The study will be conducted over 18 months. The main objective of this study is to explore the relationships between autobiographical memory and specific cognitive measures, as well as emotional and behavioural measures in patients who have suffered a moderate to severe TBI. Secondary objectives are to assess the psychometric properties of a self-defining memories questionnaire and to characterize autobiographical memory in the TBI population.
Background: Adolescence is an important period for brain development as a result of increased synaptic plasticity. Omega-3 polyunsaturated fatty acids (n-3 PUFAs) are essential nutrients for brain development and protection against oxidative stress. Walnuts have the highest n-3 PUFA concentrations of all edible plants. Objective: The investigators hypothesize that walnut intake will increase n-3 PUFA availability in the body to a level that enhances the development of the brain during adolescence. The technicians will conduct a long-term (6 months) population-based randomized controlled trial in teenagers (n=400 in each arm), and determine the effectiveness of the intervention (30 g of walnut kernels per day, ~1.5g of n-3 PUFA) in enhancing brain development. Methods: Fieldwork team will contact teenagers and families in collaboration with 20 high schools. Families will receive a basic guide on following a healthy diet in order to ensure implementation and adherence. Brain development outcomes will be measured at baseline and after the intervention. The use of computerized neuropsychological tests will provide the precision required to detect even subtle changes in brain development resulting from the nutritional intervention. Behavioral (socio-emotional) development will be assessed in order to cover a wider picture of brain development. Blood samples will be collected to measure n-3 PUFA levels before and after the intervention in a randomized subsample from both groups (control/ intervention). Linear regression models adjusted for baseline neuropsychological scores will be used to analyze the intervention effect. Implications: The outcomes of this Project are expected to be a greater understanding of the role of n-3 PUFA intake (walnut) in brain development. A major goal in public health research is to develop cost-effective health recommendations to teenagers.
Each year, ~85.3 million pregnant women are at risk of becoming infected with Plasmodium falciparum(1). Among women in sub-Saharan Africa, most of whom have some degree of clinical immunity to malaria, malaria infection in pregnancy leads to placental malaria (PM), often without clinical symptoms in the mother. The systemic and placental changes that occur with malaria in pregnancy can adversely affect the developing fetal brain, an fetal brain injury strongly affects long-term childhood neurodevelopmental (ND) and behavior but there are no published studies to date on the impact of malaria in pregnancy on childhood ND. This study, conducted in Uganda, will address the effects of malaria in pregnancy and childhood ND and define mechanisms by which malaria may lead to ND impairment including micronutrient deficiencies. ND outcomes will be measured by the following neuropsychological and behavioral tests: Mullen Scales of Early Learning, the Color Object Association Test, the Early Childhood Vigilance Test, the Behavior Rating Scales, the Behavior Related inventory of Executive Function and the Child Behavior Checklist. These tests will be given at 12, 24, 36, and 60 months of age. This study will be nested in an ongoing Ugandan IRB approved interventional trial (PROMOTE-II) (NCT02163447). Blood sampling is being conducted in the PROMOTE-II protocol for research purposes. Some of that blood will be used to test for micronutrient deficiencies as well as other immune responses to malaria.
The purpose of the study is to determine the effectiveness of the helmet-less tackling training (the HuTT Technique) intervention to reduce head impacts in high school football players and to gain an understanding of the neurocognitive effects of repetitive head impacts in football. The investigators hypothesis is that the HuTT Technique will result in a reduced frequency and magnitude of helmet impacts than the control group measured by a head impact measurement system. Also, the investigators hypothesize the HuTT Technique group will demonstrate less changes in neurocognitive scores in the mid and post season evaluations compared to the control group. Head impacts will be measured using the SIM-G impact monitor made by Triax Technology. The SIM-G impact monitor measures the location, magnitude, and direction of every head impact in real time and is stored on a protected cloud-based system. The sensor is worn by each athlete in a headband or skullcap. Neurocognitive function will be measured using the Immediate Post-concussion Assessment and Cognitive Testing (ImPACT) test. The test is used as a tool to determine baseline neurocognitive function and is used in comparison if an athlete was to be injured to ensure he/she returns to baseline. ImPACT measures memory (verbal, visual, working), processing speed and reaction time using a variety of tests. Subjects will be recruited from local high school football teams and will include freshman, sophomores and juniors. Since the study is expected to run for 2 years, seniors will not be eligible for participation. The target is to recruit at least 150 total subjects. All subjects will be equipped with a new helmet that is fitted to their head and a headband that will be used to hold the head impact telemetry sensor. In addition, all subjects will take an ImPACT test preseason, midseason and postseason. At the conclusion of each season, all of the impacts from the SIM-G impact monitor system and ImPACT test scores will be analyzed. The relevant outcome measures to be analyzed include head impact frequency, location, magnitude, symptom scores, memory, visual motor speed and reaction time composite scores. Statistical analysis will be used to determine if the HuTT intervention minimized head impacts and neurocognitive decline compared to the control group.
The purpose of the study is to describe the association/correlation between change in patient-reported cognitive symptoms and work productivity in gainfully employed patients receiving vortioxetine for a Major Depressive Episode (MDE).
Randomized, double-blind clinical trial of tocilizumab vs. placebo as add-on treatment for residual positive, negative, and cognitive symptoms in schizophrenia. The primary study hypothesis is that individuals receiving tocilizumab will show greater improvements in their PANSS total scores than those taking placebo.
Up to 50% of patients undergoing surgical aortic valve operation suffer from some level of post-operative cognitive dysfunction (POCD). Frontal lobes of the brain, where executive functions are located, are highly susceptible to trauma caused by possible blood malperfusion to these areas of the brain during surgery. Conventional and established neuropsychological test methods are poor in distinguishing these kinds of trauma, as they are isolated, structured tests that do not require multitasking and processing of multiple stimuli at the same time. The phase 1 goal of this study is to employ an experimental Executive reaction time (RT) test to see if this method could improve objective detection of subtle brain dysfunction assumed to underlie persistent cognitive, somatic, and affective complaints reported by patients who have undergone electic aortic valve replacement (AVR) surgery. Phase 2 of the study will concentrate on patients undergoing transcatheter aortic valve implantation (TAVI).
