NCT ID: NCT01370954 Completed - Clinical trials for Mild Cognitive Impairment

NAC-003 P.L.U.S. Program (Progress Through Learning Understanding & Support)

Start date: May 2011
Phase: N/A
Study type: Observational

This study will be an observational study in which patients who have been prescribed CerefolinNAC® are invited to participate in surveys regarding their experiences with CerefolinNAC®. CerefolinNAC® is a medical food indicated for the distinct nutritional requirements of individuals under treatment for early memory loss with particular emphasis for those individuals diagnosed with or at risk for neurovascular oxidative stress and/or hyperhomocysteinemia; mild to moderate cognitive impairment with or without vitamin B12 deficiency, vascular dementia or Alzheimer's disease. The purpose of this study is to increase the understanding of the role of CerefolinNAC® in managing proper neuronal function in the brain, provide patients with personalized education and support, and contribute to the overall understanding of the needs and concerns of patients being treated for early memory loss.

NCT ID: NCT01354691 Completed - Dementia Clinical Trials

Safety and Efficacy Study of Ladostigil in Mild to Moderate Probable Alzheimer's Disease

Start date: February 2011
Phase: Phase 2
Study type: Interventional

For many, Alzheimer's disease is the number one medical issue facing our aging society. It is a late onset neurodegenerative disease, frequently under diagnosed, that impairs memory and cognitive performance. There are no known treatments that can either prevent or reverse its progression. Consequently, there still remains a need to evaluate treatments which can better stabilize the symptoms of this disease. These symptoms frequently include decreased functional capacity and negative psychological attributes (e,g, depression, anxiety) in association with the memory and cognition deficits. This current study is being done to assess an investigational compound that has been designed to not only improved the cognitive status of affected patients but to also better manage all symptoms. Hence, the ultimate goal is to provide patients with an improved quality of life by slowing the progression of this neurodegenerative disease

NCT ID: NCT00597376 Completed - Clinical trials for Subjective Memory Loss in Older Persons

Study of the Effects of Cerefolin NAC on Inflammation Blood Markers in Older Individuals With Memory Complaints

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

The purpose of this six-month research study is to determine if Cerefolin NAC reduces levels of substances in the blood that may be associated with thinking ability and the health of brain cells in subjects with memory concerns when compared to a standard multivitamin. Cerefolin NAC is available as a dietary supplement via a prescription from a physician. The multivitamin used in the study contains the Recommended Daily Intake recommended for older persons.

NCT ID: NCT00400790 Completed - Dementia Clinical Trials

Organ Protection for Coronary Artery Bypass Graft (CABG): Propofol Versus Desflurane

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

Background: Different anaesthetic agents have been shown to have different protective effects upon heart, brain and renal function under ischaemic conditions (oxygen starvation). Cardiopulmonary bypass takes over the work of the heart and the lungs during heart surgery, but oxygenation of vital organs such as the brain and heart may not be perfect, and can produce brain or heart damage as a consequence. Propofol and desflurane are commonly used anaesthetic agents, and there has been recent research to suggest that anaesthetic agents may provide some protection during periods where inadequate oxygenation occurs, with the potential to reduce the degree of organ damage. Both types of anaesthetics are used for cardiac surgery with anaesthetists choosing between them largely on the basis of personal preference. Aim: To determine whether the use of either propofol or desflurane as the primary anaesthetic agent, can lead to differences in postoperative brain function, total morbidity or cost, following coronary artery surgery with cardiopulmonary bypass. Methods: Patients will be recruited by professional research staff and will be randomised into one of two groups (90 in each group). They will receive a standardized technique for anaesthesia, cardiopulmonary bypass and postoperative ICU treatment. The only difference between the 2 groups will be as to which anaesthetic agent they receive during the surgical period, desflurane or propofol. Measurements will involve i) brain function testing before and 3 months after surgery ( a set of 10 verbal or manual tests), ii) incidence of delirium in the immediate postoperative period (a survey form), iii) incidence of total postoperative morbidity and iv) cost of hospital stay. Data collection will be by anaesthesia and research staff and a neuropsychologist will employed for performing the brain function testing. Anticipated timeline: Initial recruitment completed by 15-18 months following trial commencement. Follow up completed 3 month after the last enrolment. Data validation, statistical analysis and manuscript preparation completed by 24 months.

NCT ID: NCT00329758 Completed - Head Injury Clinical Trials

Effect of Rosuvastatin on Amnesia and Orientation Through Galveston Outcome Amnesia Test in Moderate Head Injury

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

The purpose of this study is to determine whether rosuvastatin is effective in the management of moderate head injury by improving amnesia and orientation.

NCT ID: NCT00293176 Completed - Memory Loss Clinical Trials

The Evaluation of the Efficacy and Safety of Donepezil Hydrochloride in Subjects With Mild Cognitive Impairment (MCI)

Start date: December 2003
Phase: Phase 4
Study type: Interventional

To investigate the efficacy and safety of donepezil in individuals with mild cognitive impairment on measures of cognition, global function and behavior.

NCT ID: NCT00288314 Completed - Anxiety Clinical Trials

fMRI in Posttraumatic Stress Disorder (PTSD) During Working Memory Updating

METRAPI
Start date: January 2007
Phase: N/A
Study type: Observational

Neuropsychological studies investigating trauma-exposed and posttraumatic stress disorder (PTSD) subjects have generally underlined the significantly poorer performance of tasks that require attention, concentration, and verbal memory, and difficulty in regulating memories surrounding the traumatic event. A previous study (El Hage et al. Cognitive Neuropsychiatry, 2006) revealed that the trauma-exposed subjects scored higher on anxiety/depression scales, and lower on processing speed tests. Moreover, the study showed significant impairment in working memory partially mediated by speed processing, but not by anxiety or depression. These results suggest that processing speed makes a major contribution to trauma-related working memory decline, and needs to be investigated in further studies.The aim of the present study is to explore correlation between hippocampus volume, frontal dysfunction and cognitive slowing in trauma-exposed subjects, while examining brain activation during performance of working memory tasks using functional magnetic resonance.

NCT ID: NCT00142493 Completed - Memory Losses Clinical Trials

Effect of Affective Content on Drug Induced Amnesia of Episodic Memory

Start date: September 2004
Phase: Phase 1
Study type: Interventional

The purpose of this research is to understand how some of the drugs commonly used in anesthesia impair memory. We are particularly interested in whether the emotion associated with a memory influences how well these drugs are able to block memory. We are studying four commonly used drugs—propofol, thiopental, midazolam, and dexmedetomidine, all of which may have slightly differing effects. We will also study an inactive substance, called a placebo, that should have no effect. The results of this study will provide information that will be useful in understanding how memory works, how these drugs affect memory, and possibly why some people don't have their memory blocked as easily as others.

NCT ID: NCT00051402 Completed - Postmenopause Clinical Trials

Phytoestrogens and Memory Decline in Menopause

Start date: December 2002
Phase: Phase 2
Study type: Interventional

The purpose of this study is to investigate whether soy-derived phytoestrogens taken as dietary supplements improve memory function in postmenopausal women who have experienced early memory decline.

NCT ID: NCT00001362 Completed - Healthy Clinical Trials

Magnetic Resonance Imaging for the Study of Patients With Neurological Disorders

Start date: December 1992
Phase: N/A
Study type: Observational

This study is divided into two parts. The first part of the study will use MRI technology to view the brain structure of patients with neurological disorders and normal volunteers. This portion of the study will attempt to detect specific areas of damage in the brains of patients with amnesia and dementia. It will also try to correlate the amount of brain damage with performance on tests used to measure memory. In the second part of the study, researchers plan to use MRI technology to study brain function of patients with neurological disorders and normal volunteers when they perform tasks. MRI signals during task performance will be used to record areas of the brain receiving more blood flow indicating increased activity. Researchers believe this study will help improve existing methods of evaluating patients with neurological disorders. In addition, this study may contribute information about areas of the brain involved in thought processing and motor and sensory function.
