Active clinical trials for "Cognitive Dysfunction"

The objective of this study is to determine whether horticultural therapy would improve the psychological well-being older adults who are at risk of memory (cognitive) decline. 100 elderly subjects who are at risk of cognitive decline will be randomized into the active horticultural therapy or to the waitlist control group. Sessions will be conducted weekly for 9 months, and participants will be assessed at 3 time-points: at the start of the study, at 3 months and at 9 months. It is hypothesized that participants who undergo horticultural therapy will perform better on neuropsychological tests when compared to control, and that they will have improved psychological well-being and functional outcomes.

This study will use systems biology techniques, especially RNA-seq, to understand cognitive impairment after sepsis requiring an intensive care unit (ICU) admission.

PRIME aims to demonstrate through neurocognitive assessment that BICU patients will have a degree of neurocognitive dysfunction following a major burn, that this neurocognitive dysfunction is due to an underlying neuroinflammatory process by fMRI neuroimaging techniques, and that the neurocognitive deficit is associated with a reduced quality of life.

To study the correlation of POCD with olfactory function. To explore whether enhanced olfactory stimuli can reduce the risk of POCD as a preventive strategy.

A prospective observational multicenter study aiming to describe incidence, and identify predictors for development of poststroke dementia (PSD) and mild cognitive impairment (MCI) after stroke

The purpose of this study is to explore the relationship between diabetes and cognitive impairment by olfactory function assessment and functional MRI.

The primary purpose of this study is to apply state-of-the-art Magnetic Resonance Imaging (MRI) and Magnetic Resonance Spectroscopic Imaging (MRSI) techniques to measure changes over time in the brain.

Patients with the APOE-ε4 genotype are at increased risk of both vascular dementia and peripheral vascular disease. Patients undergoing major vascular surgery are at particularly high risk of delirium and other, more subtle, changes in cognitive function following surgery. The hypothesis of this trial is that the APOE-ε4 genotype is associated with both delirium and postoperative cognitive dysfunction (POCD).

Probands with MCI are at high risk to develop Alzheimer´s dementia (AD). Simvastatin may lower the production of Amyloid, a hallmark of AD in the brain. The primary hypothesis of the study is that 60 mg Simvastatin significantly reduces the Clinical Dementia Rating -Sum of boxes (CDR-SOB) in individuals with MCI as compared to MCI receiving placebo or 20 mg Simvastatin

This is a sequential mixed study to test the hypothesized models with seven hypotheses of the relationship between cognitive deficit (subject and objective) and neuropsychiatric symptoms (NPS) among persons with mild cognitive impairment (PwMCI). The study will also examine the psychometric properties of the Chinese version of Mild Behavioural Impairment -Checklist (MBI-C).
