NCT ID: NCT00561678 Completed - Clinical trials for Postoperative Delirium

Perioperative Cognitive Function - Dexmedetomidine and Cognitive Reserve

Start date: February 2008
Phase: Phase 4
Study type: Interventional

Elderly patients who undergo anesthesia and non-cardiac surgery are subject to deterioration of brain function including the development of postoperative delirium (PD) and postoperative cognitive dysfunction (POCD). These disorders cause disability, distress for both patients and their families, are associated with other medical complications and account for significant additional health care costs. We currently use relatively primitive approaches to preventing and treating PD and POCD. Dexmedetomidine is a drug used for sedation in critically ill patients that provides some pain relief and controls the bodies response to stress. The sedation produced by dexmedetomidine appears more similar to natural sleep than any other drug used for anesthesia and postoperative sedation. Data suggesting that dexmedetomidine can prevent delirium following cardiac surgery and the developing understanding of the causes of PD and POCD suggest that dexmedetomidine will be particularly effective.

NCT ID: NCT00469482 Completed - Clinical trials for Cognitive Impairment

The SOMNUS Study: Sedative Optimization Via Monitoring Neurological Status

SOMNUS
Start date: June 2007
Phase: N/A
Study type: Interventional

A combined strategy of Richmond Agitation and Sedation Scale (RASS) clinical targeting plus bispectral index (BIS) guided sedation in mechanically ventilated, critically ill patients will decrease time on mechanical ventilation, decrease the duration of intensive care unit (ICU) delirium and coma, and will improve subacute neurocognitive function when compared to sedation guided by RASS targeting alone.

NCT ID: NCT00446485 Completed - Clinical trials for Mild Cognitive Impairment

Efficacy and Safety of Ginkgo Biloba Extract in Mild Cognitive Impairment and Cerebrovascular Insufficiency

Start date: May 2007
Phase: Phase 4
Study type: Interventional

The purpose of the study is to determine weather Ginkgo biloba standardized extract (24% ginkoflavonoglicozides and 6% terpenes) is effective in treatment of cognitive and concentration impairment

NCT ID: NCT00321971 Completed - Depression Clinical Trials

Prevention of Depression in Spouses of People With Cognitive Impairment

Start date: February 2007
Phase: N/A
Study type: Interventional

This study evaluates the effectiveness of a problem-solving training program in preventing depression in the spouses or family caregivers of persons with mild cognitive impairment or early dementia.

NCT ID: NCT00300716 Completed - Multiple Sclerosis Clinical Trials

Trial of Memantine for Cognitive Impairment in Multiple Sclerosis

Start date: April 2004
Phase: Phase 2/Phase 3
Study type: Interventional

This study is designed to determine whether memantine is an effective treatment for memory and cognitive problems associated with multiple sclerosis when compared to placebo.

NCT ID: NCT00294307 Completed - Alzheimer Disease Clinical Trials

Enhancing Care Coordination: Hospital to Home for Cognitively Impaired Older Adults and Their Caregivers

Start date: February 2006
Phase:
Study type: Observational

Aim 1. To compare across three hospital sites the effects on health and cost outcomes observed by the following three interventions, each designed to enhance adaptation and improve outcomes of hospitalized cognitively impaired elders and their caregivers: 1. augmented standard care (ASC) - standard hospital and, if referred, home care plus early identification of CI during the patients' hospitalization by trained registered nurses (RNs) with immediate feedback to patients' primary nurses, attending physicians and discharge planners; 2. resource nurse care (RNC) - standard hospital and, if referred, home care plus early identification of CI during the patient's hospitalization by trained RNs and hospital care by RNs trained in the use of expert clinical guidelines developed to enhance the care management of hospitalized cognitively impaired elders and to facilitate their transition from hospital to home; or, 3. advanced practice nurse care (APNC) - standard hospital care plus transitional (hospital to home) care substituting for standard home care and provided by APNs with advanced training in the management of CI patients using an evidence-based protocol designed specifically for this patient group and their caregivers. [H1] We hypothesize that health and cost outcomes with APNC, a comprehensive intervention designed to meet the unique needs of cognitively impaired older adults hospitalized for an acute medical or surgical event and their caregivers will be associated, relative to health and cost outcomes with ASC and RNC, with improvement in patient, caregiver and cost outcomes. [H2] We hypothesize that improvements in patient, caregiver and cost outcomes observed for the RNC group will be greater than those observed for the ASC group. Aim 2. To compare within each site and over time, health and cost outcomes (identified in Aim 1) from patients treated with either ASC or RNC, both relatively lower intensity interventions, with the outcomes of patients at the same site observed after switching to APNC, a high intensity intervention. [H3] We hypothesize that compared to patients receiving the ASC or the RNC interventions, patients at the same site will have improved patient, caregiver and cost outcomes after the site switches to APNC. [H4] We hypothesize that patient, caregiver and cost outcomes achieved by the groups receiving APNC interventions at T1 and T2 will be similar.

NCT ID: NCT00276341 Completed - Clinical trials for Multiple Sclerosis, Relapsing-Remitting

Study on the Effectiveness of EGb 761® vs Placebo Used for Cognitive Impairment in Patients With Multiple Sclerosis

Start date: August 26, 2003
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine whether the use of EGb 761 by patients with Relapsing-Remitting Multiple Sclerosis is effective in improving cognition, when compared to placebo.

NCT ID: NCT00270647 Completed - Prostate Cancer Clinical Trials

Physicians' Health Study II

PHS II
Start date: July 1997
Phase: N/A
Study type: Interventional

The use of vitamin E, vitamin C, beta carotene, and/or multivitamins may keep cancer, cardiovascular disease, eye diseases, or cognitive decline from occurring. This randomized clinical trial studied vitamin E, vitamin C, beta carotene, and/or multivitamins to see how well they work compared with placebos in preventing cancer, cardiovascular disease, eye disease, and cognitive decline in male doctors aged 50 years and older.

NCT ID: NCT00257712 Completed - Aging Clinical Trials

SMART: Somatotrophics, Memory, and Aging Research Trial

Start date: February 2006
Phase: Phase 2
Study type: Interventional

The purpose of the SMART study was to better understand whether the body's own production of growth hormone (GH) would improve memory and problem solving ability, or cognitive function. The study was a double blind, placebo-controlled study of the cognitive effects of growth hormone releasing hormone (GHRH) in healthy older men and women and in those with mild cognitive impairment (MCI).

NCT ID: NCT00231894 Completed - Schizophrenia Clinical Trials

Pioglitazone as a Treatment for Lipid and Glucose Abnormalities In Patients With Schizophrenia

Start date: May 2005
Phase: Phase 4
Study type: Interventional

This is a study with an approved drug for treating type 2 diabetes, for its effects on treating glucose and lipid abnormalities in patients being treated with first or second-generation antipsychotics, and comparison of effects of this drug with another treatment lifestyle modification. Patients who meet inclusion criteria will be treated with pioglitazone for 12 weeks. They will be evaluated for fasting glucose and lipids, glucose-tolerance tests, and neurocognitive battery and tests of verbal memory at baseline and during treatment with pioglitazone.
