Active clinical trials for "Cognitive Dysfunction"

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 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.

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.

The purpose of the programme is to facilitate the anticipation of dementia both in elderly patients suffering from this disease and in their carers and to diminish care burden in order to improve quality of life and daily functioning.

The purpose of this study is to identify cardiac patients' degree of unappreciated mild impairment in cognitive function patterns of cognitive function, and influencing factors related to cognitive functioning during hospitalization. The results from the study will contribute to tailoring the delivery of patient education to optimize patient understanding of information in future clinical practice. It is hypothesized that the study will demonstrate the following: The degree of cognitive function for patients hospitalized in a CICU will be below the scores for normal functioning adults. Patients with acute cardiovascular conditions will score differently in cognitive functioning at various times throughout their hospitalization. Relationships between cognitive function and following variables: Patients with greater sleep deprivation or fatigue will exhibit lower cognitive functioning. Patients with greater hunger will exhibit lower cognitive functioning. Patients who are experiencing greater anxiety will exhibit lower cognitive functioning. Patients who are experiencing depression will exhibit lower cognitive functioning. Patients who have undergone or will undergo shortly treatment or procedures will exhibit lower cognitive functioning.

The aim of this study is to quantify the incidence of postoperative cognitive dysfunction in the elderly patient (>60y) after total hip or knee replacement surgery. The hypothesis is that the fast-track methodology with a mean hospital stay less than 3 days will help to minimize this reduction in memory and concentration.

Many older adults have undetected health problems and lack basic prevention measures. Failure to identify and treat these conditions can lead to unnecessary morbidity and mortality and a decreased quality of life. Traditional screening and intervention programs, usually based in primary care providers' offices, have been insufficient, particularly in medically underserved populations. Alternate sites for screening and intervention have begun to receive attention and may hold promise. The emergency department (ED) is the entry point for access to medical and social services for many patients and has the potential to serve as a site to identify older adults with unmet needs. However, we do not know the prevalence of depression and cognitive impairment and how they differ by mode of arrival of the patient to the ED. Second, a question remains as to the validity of screening patients during an acute illness. Upon completion, this study will describe the epidemiology of the population of older adults presenting to the ED.

The objective of the present research is to evaluate the incidence and independent predictors of delirium observed among patients after cardiac surgery. Moreover, to asses the sensitivity and specificity of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria (DSM-IV) and International Statistical Classification of Diseases and Health Related Problems - Tenth Revision criteria (ICD-10), and the cut-off values of the Memorial Delirium Assessment Scale (MDAS) and Delirium Index (DI) in diagnosing postoperative delirium.

An increasing number of Veterans are anticipated to develop chronic kidney disease (CKD) and require hemodialysis (HD) treatments as the Veteran population ages. In 2003, approximately 290,000 US citizens were receiving HD and an estimated 19 million were affected by CKD. The annual growth rate is predicted to be 7% per year with 500,000 Americans receiving HD treatment by 2010. In 2005, approximately 2500 Veterans were receiving HD with growth expected to parallel that seen in the general population. Whereas Alzheimer's disease is the leading cause of dementia in the general population, growing evidence suggests that patients with advanced CKD experience cognitive deficits related to accelerated cerebrovascular disease. Patients with advanced CKD have been shown to have a high prevalence of sub-clinical cerebrovascular damage on imaging studies and a heavy burden of vascular risk factors such as diabetes, elevated cholesterol, and hypertension. Many of the cognitive deficits related to cerebrovascular disease may go unrecognized by routine measures of cognition. HD patients have increased number of hospitalizations, and several compliance issues ranging from congestive heart failure to dangerous electrolyte imbalances. Impaired cognition in this population is likely to have a significant impact on self-care and compliance with complex medical regimens. Currently, the severity and scope of cognitive impairment related to vascular disease is not well known in patients with advanced kidney disease. Additionally, the relationship between cognitive impairment and measures of self-care independence are not well known. Loss of independence and function secondary to impaired cognitive function is likely to be a significant problem for patients with advanced kidney disease. Early identification of functional impairment, particularly instrumental activities of daily living (IADL), will allow for rehabilitation intervention. Maintaining or improving functional independence through intensive rehabilitation could translate into better compliance and lower hospitalization rate among HD patients. Information obtained from this study is likely to heighten awareness of cognitive impairment and the functional consequences in Veterans with advanced kidney disease. Primary objectives are to determine: The range of cognitive deficits with emphasis on domains affected by vascular disease in patients with advanced CKD and those receiving hemodialysis. The associations between severity of cognitive impairment and severity of kidney disease. The prevalence of impaired IADLs and the level of health-related quality of life (HRQOL) in patients with advanced CKD and those requiring hemodialysis. The relationship or association of cognitive impairment with IADL and HRQOL. Secondary objective is to determine: 1. The relationships among cerebral and carotid blood flow, carotid artery stiffness, and renal specific metabolic abnormalities with cognitive impairment.

This study is collecting tissue specimens (blood, urine and saliva) from up to 1000 patients, with and without cognitive disorders, to store in the Bio Bank for future research. The specimens could be used in future research projects that could help improve the accuracy of diagnosis of a disease, predict who might develop a disease, help monitor the disease, or improve the understanding of the disease. Patients are only being recruited from Beaumont Hospitals Geriatric Clinic.
