Active clinical trials for "Cognition Disorders"

ADHD is often associated with sleep difficulties. Attention-deficit/hyperactivity disorder (ADHD) is the most common problem presented to children mental health services. The disorder affects approximately 5 % of school-age children. The core symptoms of this disorder include varying degrees of inattention, impulsiveness and restlessness. In addition to the core symptoms, ADHD is associated with other problems (e.g. academic underachievement, poor social relations and sleep disturbances). Despite clinical observations of sleep problems in children with ADHD, there is little empirical research on this topic. The prevalence, type of sleep problems, and significance of these sleep disturbances in children with ADHD remain undocumented. The objective is to determine the relationship of sleep problems to attention deficit/hyperactive disorder, comorbid disorders, and the effect of stimulant treatment.

The aim of our study is the analysis of sleep phases and quality as well as the detection of respiratory pauses in subjects with cognitive disorder. To assess whether sleep quality is associated with the blood-brain barrier and Alzheimer's disease, which may be indicative of an early, non-invasively measurable change in brain activity in the early stages of Alzheimer's disease.

The purpose is to investigate the COVID-19 prevalence, associated morbidity and long-term cognitive deficits in consecutive patients presenting with acute neurological symptoms

Background: - The amount of blood flowing in brain areas goes up when those areas are being used for activities, such as movement or seeing. Functional magnetic resonance imaging (fMRI) is a common way of measuring blood flow in the brain. Near infrared spectroscopy (NIRS) can also be used to study blood flow in the brain. However, NIRS has not been used as often as fMRI. Researchers want to compare fMRI and NIRS to see whether they give similar results. These studies will be used to look at people who have had a traumatic brain injury. Objectives: - To test how well NIRS measure changes in blood flow in the brain after a traumatic brain injury. Eligibility: Individuals between 18 and 60 years of age who have had a traumatic brain injury. Healthy volunteers at least 18 years of age. Design: Participants will be screened with a physical exam and medical history. Researchers may ask to see brain images during from previous MRI scans. Participants will have a NIRS scan of the brain. They will be asked to do certain tasks while inside the scanner. These tasks will involve responding to images that appear on a screen. Treatment will not be provided as part of this study.

We aim to make clear the impact with the mechanisms of variant pathological injuries on the outcomes of CSVD, to find independent imaging markers and establish prediction model of it.

HYPOTHESIS: The Spanish version of the Everyday Cognition Battery Scale (ECB) is valid and reliable in the Spanish population. OBJECTIVES: • Providing a validated scale in Spanish to evaluate daily cognition in older adults. SPECIFIC OBJECTIVES: Translating the original English version of the ECB into Spanish. Adapting the scale to the sociocultural context of Spain. Checking the psychometric characteristics (reliability and validity) of the translated version . STUDY DESIGN: Cross-sectional descriptive study. Permission to use the ECB scale will be requested to the author, Allaire JC. Translation and adaptation of the scale. Administration of the four tests of the ECB to the individuals participating in the study. Administration of the Rapid Evaluation of Cognitive Functions (RECF) and Lawton and Brody scales. Analysis of the psychometric characteristics of the translated version. The protocol has been authorized by the Ethics Committee of the Salamanca health area to make the project possible.

There is little accurate data in the literature at present on oral problems of hyperactive children, especially regarding care needs that would justify an assumption oral specific. The purpose of this study is therefore to have accurate data regarding the risk of caries, other oral diseases like periodontal disease, trauma, and assess the needs dental care and problems in cooperation for dental care in a population of children and adolescents with hyperactivity disorder with attention deficit. Finally, it has recently been described as the sleep disordered breathing was not uncommon in disorder attention deficit/hyperactivity disorder, whether snoring and/or apnea. But it is now accepted that some features of facial morphology favoring pharyngeal congestion occur in individuals with obstructive sleep apnea (hyperdivergent typology with increased anterior facial height and decreased posterior facial height, becoming the facial retrognathia, pharyngeal congestion, elongation and thickening of the soft palate, low position of the hyoid bone). A cephalometric analysis of craniofacial architecture and relationships with the soft tissue surrounding skeletal structures will detect if any of these specific characteristics that could promote sleep disordered breathing are found in disorder attention deficit/hyperactivity disorder prevalence with a particular.
