Filter by:The purpose of this study is to understand the effect of age on language abilities. The investigators aim at investigating the cerebral modifications that take place in normal aging, at the functional an anatomical level.
The effect of supplementation using both protein and multiple micronutrients in preschool age children on cognitive performance and growth is unknown. The study will compare the effect of combination of protein and multiple micronutrients on indicators of cognitive performance and growth in preschool age children. Cognitive performance and anthropometric assessments will be measured at baseline and at 6 months.
The purpose of this study is to determine whether BRAND'S® Essence of Chicken are effective in the promotion of resilience and resistance to stress-associated cognitive inhibition.
The primary aim is to collect data to determine the correct effect size on the primary outcome to aid in the design of a larger study: The primary outcome is to determine if lipoic acid and omega-3 fatty acids can improve cognitive function in people with multiple sclerosis that have cognitive dysfunction.
This is a study of the effects of tDCS on smoking, craving for cigarettes, cognition, and psychiatric symptoms in schizophrenic patients who are current smokers or have a history of regular cigarette smoking. It assesses smoking with CO monitoring, nicotine and nicotine levels, and craving with QSU scale and response to craving slides. Cognition is measured by MCCB, symptoms are measured by PANSS and hallucination scale. This is a double-blind sham-controlled study with active tDCS 2ma or 20 minutes over 5 days, and sham tDCS for 40 seconds on each sham occasion.
The investigators propose to test whether curcumin nanoparticles will improve behavioral measures and biomarkers of cognition and neuroplasticity in patients with schizophrenia who are already receiving a stable dose of antipsychotic.
The present study will investigate the effects of aerobic exercise on cognition and growth factors including brain-derived neurotrophic factor (BDNF) in young adults aged 15-21 years. The included subjects will be randomized to three different groups including one control group and two exercise groups. Subjects randomized to the exercise groups will complete 30 minutes of aerobic exercise 3 times a week for 9 weeks incorporating low (group I) or high (group II) intensity aerobic exercise. The exercise will be conducted as running or indoor cycling (supervised). At baseline and 9-weeks follow-up all subjects will complete two cognitive tests (measures of concentration and sustained attention), a maximal cycling test (direct measures of VO2max), an intelligence quotient test, anthropometric measures, fasting blood samples and blood samples immediately following the cycling test. The blood samples will be analyzed for growth factors including BDNF and metabolic factors.
This study seeks to assess the effects of lisdexamfetamine (trademark name: Vyvanse; LDX) on executive function and prefrontal cortex activation in menopausal women ages 45-57, who report subjective cognitive difficulties. This protocol will recruit women from Dr. Epperson's ongoing study, Protocol #812470, to examine the impact of LDX on brain activation during performance of cognitive tasks specifically probing prefrontal cortex function.
Rationale: Abnormally low and high levels of insulin-like growth factor-I (IGF-I) are both associated with increased metabolic risk. Since (U-shaped) associations of IGF-I, within the normal range, have also been found with cardiovascular risk factors and disease in the general population, it would be interesting to investigate if this association can also be found in growth hormone deficient (GHD) adults treated with Growth Hormone (GH). This could be of interest for endocrinologists prescribing GH in clinical practice because strict dosing may become even more important. Next to that, scientific evidence for clinical practice is wanted. Objective: Next to cardiovascular risk factors (main objectives: body composition and lipid profile; secondary objectives: remainder) we investigate the effect on glucose metabolism, physical performance, and neuropsychological functioning of different levels of IGF-I in GH treated GHD men and women. Study design: Open-label randomized trial. Study population: At least 32 subjects, both childhood as adult onset GHD men and women, receiving GH treatment for at least one year, with an age between 20 and 65 years. Intervention: At entry subjects are already receiving GH treatment according to general clinical practice, and are expected to demonstrate an IGF-I concentration of 0 - 1 SD score (SDS) (normal dose). The group of men and group of women will be randomized to receive either a decrease of their regular dose of GH treatment (IGF-I target level of -2 - -1 SDS) (low dose), or an increase of their regular dose, (IGF-I target level of 1 - 2 SDS) (high dose) for at least 24 weeks.
Dopamine receptor occupancy and brain metabolism were measured using positron emission tomography after the administration of aripiprazole. Working memory performance was also measured using N-back task. The investigators explored the relationship between changes in brain metabolism and working memory performance.
