View clinical trials related to Cognitive Function.
Filter by:Through prospective registration and follow-up, this study will collect data of patients with intracranial/carotid stenosis, including clinical information, neuropsychological scales, multimodal magnetic resonance images. The investigators aim to analyze clinical and imaging characteristics of patients with cognitive impairment related to intracranial/carotid stenosis, in order to achieve early identification of cognitive impairment.
The current study is a five-arm, single bout program aiming to assess the effects of training volume and intensity of acute resistance exercise on inhibitory control on neurocognitive function with respect to event-related potential in adults aged 20 - 26 years.
A randomized controlled trial will be conducted. Patients with asymptomatic intracranial / carotid stenosis will be randomized into two arms (1:1): an intervention arm and a control arm. Patients in the intervention arm will be treated with standard medical treatment combined with Natto Products V, whereas Patient in the control arm will be treated with only standard medical treatment . And the impact of Natto Products V on improving cerebral blood flow and cognitive function in patients with asymptomatic intracranial / carotid stenosis will be assessed by neuropsychological scale and multimode magnetic resonance imaging.
We aim to clarify the relationship between sleep hygiene and the onset of sarcopenia or cognitive dysfunction using sleep time, arousal, and sleep quality as indicators in COPD or IPF patients, and clarify the effects of sleep hygiene on disease progression and life prognosis.
Regular exercise during pregnancy and postpartum leads to health benefits for mother and child. Inactivity during pregnancy and after delivery is now treated as risky behavior. Physically active pregnant women significantly less often suffer from, among others, gestational diabetes, excessive weight gain, lipids disorders, hypertension, preeclampsia, depressive symptoms, functional and structural disorders, including stress urinary incontinence, back pain or diastasis recti abdominis (DRA). Prenatal physical activity reduces the risk of premature delivery and miscarriage, fetal macrosomia, complications in labor or the risk of metabolic disorders in children. High-intensity interval training (HIIT) has become one of the most popular trends in the fitness sector. The effectiveness of HIIT on a number of health indicators has been proven in various populations but limited data are available on HIIT during pregnancy. The first hypothesis is that the HIIT, implemented during pregnancy and after childbirth, as a stronger exercise stimulus, will have a better impact on selected biological and psychological parameters of mothers, as well as on selected health parameters of their children, compared to the MICT (moderate intensity continuous training). Therefore, it promises better preventive effects on pregnancy complications and ailments as well as non-communicable diseases occurring in these populations. In the second hypothesis, it was assumed that HIIT and MICT implemented during pregnancy and after childbirth, tailored to the specific needs of the perinatal period, will not differ in the effectiveness of maintaining normal functional parameters in women, including prevention of urinary incontinence, back pain, DRA, etc. Pregnant women who apply for the study will be divided into three groups: those attending the HIIT, MICT or educational programs. During the study, the participants will be under standard obstetric care. As comparative groups, non-pregnant women will be also recruited. The investigators will collect data on selected biological, functional and psychological parameters in the study women at each trimester of pregnancy, during the puerperium and one year after childbirth. The data from the medical documentation on the course of childbirth and the assessment of the new-born, as well as the results of preventive examinations in the study women's children aged one, two, four and six years will be also analyzed.
This study is a postmarketing requirement jointly carried out by four NDA holders (Bayer AG, Bracco, GE Healthcare and Guerbet) and the CRO IQVIA. The study aims to create detailed images of the organs and tissue of the human body during x-ray, CT-scan or MRI investigations, doctors are using contrast media (a kind of dye) which can be given to patients by injection into a blood vessel or by mouth. In this study researchers want to find out whether so called gadolinium-based contrast agents (GBCAs) have an effect on body movement and mental skills when given to participants multiple times within 5 years. The study plans to enroll about 2076 participants suffering from a condition for which they are likely to have at least annually a MRI or another imaging examinations. Only adults up to 65 years will be considered to join this study. During the study duration of 5 years participants will receive annually a MRI or other imaging tests (such as CT-scan, x-ray) and will visit the study doctor at least 7 times for physical examinations, laboratory investigations and tests on body movement and mental skills.
This study will determine whether acute ingestion of a high fat "Bulletproof Coffee" will lead to changes in plasma triglycerides, immune cell function, as well as cognitive function when compared to a black coffee.
Endocrine therapy (ET) is widely used to treat hormone receptor positive breast cancer and prevent recurrence by downregulating estrogen function. However, ETs readily cross the blood brain barrier and interfere with the action of estrogen in the brain. Estrogen supports cognition and menopausal status is closely linked to cognitive health in women. This has raised concern that anti-estrogen ETs may affect cognition and brain health in breast cancer survivors. However, evidence across existing studies is inconsistent and these effects remain poorly understood. The incomplete understanding of the effects of ET are likely due to limitations of earlier studies - namely, the under-appreciation of the role of menopausal status and insensitivity of standard cognitive measures. This research project will address these earlier limitations by specifically comparing ET effects by menopausal status, and using highly sensitive, task-related functional magnetic resonance imaging (fMRI) measures to assess the effects of ET on brain function.
This study aims to study the relationship between diet and cognitive function among 4-5-year-olds.
While it is well established that physical inactivity is a modifiable risk factor for vascular disease and cognitive decline, the mechanism by which exercise exerts its protective effect on the cerebral circulation and cognition is unknown. This knowledge gap was recognized recently in the Centers for Disease Control & Prevention and the Alzheimer's Association document "National Public Health Road Map to Maintaining Cognitive Health". Our rationale for these studies is that the identification of physical exercise as a lifestyle factor able to improve cerebrovascular reserve and cognition would establish a strong scientific framework justifying design of a randomized clinical trial that could evaluate the role of physical activity in cerebrovascular health and function. This research is based on data we obtained from a cross-sectional study that showed significant relations between physical fitness, vascular regulation and cognition. Cerebrovascular reserve and cognition were better maintained in women who were physically active but reduced in women who were sedentary. Our central hypothesis is that regular aerobic exercise mitigates age-related decreases in cerebrovascular reserve, which in turn imparts benefits in cognition. Further, we believe that these effects will persist after the structured aerobic exercise program is terminated. Our 18 month study began with a 6-month baseline period, followed by a 6-month exercise intervention, and a 6-month follow-up period. In addition, there are 5-year and 10-year follow-up periods. Volunteers (men and women aged ≥ 55 years) from the community were recruited using a variety of recruitment methods including media and distribution lists. After the baseline (pre-training) measurements, participants underwent a six-month aerobic training program, following guidelines previously used by us and according to the new exercise guidelines for older adults established by American College of Sports Medicine and the American Heart Association. The study involves comprehensive assessments of physical fitness, cerebrovascular responses to carbon dioxide at rest and during sub-maximal exercise, and an extensive battery of cognitive function tests.
