Active clinical trials for "Cognitive Dysfunction"

To study on the Postoperative Cognitive Dysfunction: Correlations With the Gene Polymorphism and the Concentrations of Plasma Homocysteine, Folic Acid and Vitamin B12. To explore whether the gene polymorphism and the concentrations of plasma homocysteine, folic acid and vitamin B12 could be used as predictor(s) of POCD and to provide reference for POCD prevention, early detection and timely diagnosis and treatment.

This protocol describes a study to validate Neurotrack's visual paired comparison task, aimed at early detection and monitoring of memory impairment. The investigators will determine whether the novel task developed by Neurotrack is associated with markers of brain pathology associated with very early Alzheimer's disease. The elderly subjects studied will be cognitively normal (CN) or have amnestic mild cognitive impairment (aMCI). For the current study, the primary brain pathology parameters will be derived from MRI scans. Data from this study will be correlated with data from a parallel study designed to validate a larger group of new cognitive tasks by correlating test performance with a broader array of biomarkers of Alzheimer's disease.

The purpose of this study is to evaluate the psychometric properties of a Self-administered Memory Screening Test with Automated Reporting (SAMSTAR) adapted from the Rey Auditory Verbal Learning Test (RAVLT) in normal control (NC) participants and participants with Mild Cognitive Impairment (MCI) against a standard version of the RAVLT test, administered by an examiner under the same conditions.

Pseudohypoparathyroidism type 1a (PHP1a) is a rare disease that causes childhood obesity and learning difficulties. This study will investigate eating behaviors and perform cognitive testing on children with PHP1a. The investigators will compare their results to those of healthy siblings and other obese children.

The Virtual Physiological Human: DementiA Research Enabled by IT (VPH-DARE@IT) is a four-year IT-project funded through the European Union (EU). The project consortium involves a total of 21 universities and industrial partners from 10 European countries. The project delivers the first patient-specific predictive models for early differential diagnosis of dementia and their evolution. An integrated clinical decision support platform will be validated / tested by access to a dozen databases of international cross-sectional and longitudinal studies. As a part of the VPH-DARE@IT project, a new prospective cohort will be collected in Kuopio. This prospective cohort will be used to test further the modeling approaches and tools developed by using the retrospective databases.

One important issue in older adults with cognitive problems is the higher risk of fall due to decreased motor function and balance. The objective of this study is to evaluate the repercussions of mild cognitive impairment in balance in elderly.

The purpose of this study is to determine whether simple, evidence-based clinical screening be quickly and feasibly implemented (>85% of patients in an average of <6 minutes) in large-volume urgent transient ischemic attack (TIA)/stroke clinics to identify individuals at high risk for the three most common and devastating post-stroke co-morbidities (depression, obstructive sleep apnea and cognitive disorders).

The purpose of this study is to study the impact of blood pressure on cognitive performance.

Cognitive impairment, commonly reported as difficulty with memory and executive function, is a widely recognized clinical challenge for older persons with heart failure (HF). Little is known about the relationship between brain MRI and cognitive impairment in older persons with HF. A limited number of studies have investigated brain MRI in adults with HF and produced conflicting results. Previous findings are limited by use of lower resolution scanners (1.5 Tesla), lack of MRI techniques (i.e. combining structural sequences with perfusion sequences) and recruitment of mixed age samples. Based on these limitations, the purpose of this research plan is to explore the relationship between brain MRI and cognitive impairment in older persons with HF using high resolution structural and perfusion scans. To accomplish this goal, investigators will compare 40 adults with HF who are age > 65 years old with 40 healthy, gender, age, and education matched controls. Investigators will obtain neuropsychological measures of multiple domains, as well as MRI measurements of the temporal lobe and prefrontal cortex at baseline and 12-months.

The study was designed to employ MOCA to screen mild cognitive impairment (MCI) in military retirees and to analyze the associated risk factors. As such, MOCA was revised to be validated for the Chinese context.
