Active clinical trials for "Cognitive Dysfunction"

The purpose of the PRIME Study is to examine the current management and outcomes of patients with mild cognitive impairment or dementia. Approximately 4500 patients will be enrolled in this disease registry across 12 sites in Australia. Clinical, treatment, health status and economic data will be acquired over 3 years. The study will identify the relationships among demographic variables, prognostic features, geographic setting, treatment options and clinical, economic and health status (activities of daily living and caregiver impact) outcomes.

The purpose of this study is to see whether anti-HIV drugs that reduce HIV in the blood also reduce HIV in the cerebrospinal fluid (CSF). CSF is the fluid found around the brain and spinal cord. This study also looks at whether reducing HIV in the CSF can help protect brain function. HIV can be detected in the brain and CSF early in HIV disease. Anti-HIV drugs probably reduce HIV in the CSF. This may be important because other studies have suggested high CSF HIV levels may lead to some loss of brain function.

The purpose of this study is to determine what percentage of patients have cognitive problems (for example, memory or concentration difficulties) after surgery and anesthesia, what the characteristics of these problems are, and whether they persist over time. In particular, the investigators want to study this in the French-speaking Quebec population with cognitive evaluation tools adapted for this population.

A substantial portion of people covered by Medicare will develop Alzheimer's disease and other forms of dementia that together devastate the lives of millions of people in the United States, and cost us a total of over $200 billion every year. Getting a brain scan with a PET scanner to look for abnormal brain metabolism patterns is recognized as "reasonable and necessary" for some patients with "a recently established diagnosis of dementia" (Centers for Medicare and Medicaid Services (CMS), Decision Memo CAG-00088R), but the evidence is considered less clear for patients having less severe cognitive problems, and/or for patients getting a brain scan with a PET scanner to look for abnormal proteins in the brain (CMS Decision Memo CAG-00431N). This project employs a scientifically rigorous design (prospective, multi-centered, randomized controlled trial) to determine whether such PET scanning can help distinguish more accurately than is being done in current clinical practice those patients with early molecular changes in their brains who will benefit from Alzheimer related treatments from those patients who will not, as proven by measuring to what extent the PET scans actually lead to earlier appropriate therapy, and in fact result in improved outcomes for Medicare beneficiaries and for the health care system in which they obtain care.

PLUG Dementia Trial: Patients will be screened at Intermountain Medical Center and at Intermountain affiliated anticoagulation clinics in the Salt Lake City region. Patients with atrial fibrillation that undergo a standard of care, clinically approved, left atrial appendage closure will be considered for study. All patients will be followed for 24 months, and will be assessed at the 3-, 6-, 12-, 18- and 24-months post-left atrial appendage closure as well as other visits deemed necessary for clinical care. All subjects will undergo protocol-specified laboratory tests and will complete 6 standard, validated questionnaires at each follow-up visit, except at the 3-month visit when only one questionnaire will be administered. A subset of patients (n=20), will receive a cranial MRI at baseline and 24-month visit. MRI PLUG Dementia Sub-Study: In addition to the above, 20 of the 60 subjects who are selected for participation in this sub-study will receive a cranial MRI at baseline and at the 2-year (24 months) follow-up visit.

To determine if the usage of EEG Entropy helps to reduces the incidence of POCD in elderly patients after general anesthesia.

To investigate long term affects of multiple concussions on the cognition, balance, proprioception, and biomarkers in retired National Hockey League players

The purpose of this prospective monocenter observational study is to assess the impact of the first introduction of formal home help (personalized autonomy allowance for seniors) on the quality of life of home caregivers of elderly patients with neurocognitive impairment.

This is a pilot study assessing fMRI changes and neurocognitive function in women with pre-eclampsia and healthy controls. Neurocognitive testing will be done during pregnancy and after delivery up to 2-6 weeks postpartum. fMRI will be done after delivery up to 2-6 weeks postpartum. The aims of this pilot study are therefore to 1) Determine the frequency and nature of co-morbid DTI white matter patency and fMRI functional connectivity changes in women with pre-eclampsia/eclampsia and 2) Determine the relationship between DTI white matter patency and fMRI functional connectivity changes to measurable alterations in cognitive function in this patient population. The aims of this pilot study are therefore to 1) Determine the frequency and nature of co-morbid DTI white matter patency and fMRI functional connectivity changes in women with pre-eclampsia/eclampsia and 2) Determine the relationship between DTI white matter patency and fMRI functional connectivity changes to measurable alterations in cognitive function in this patient population.

The primary objectives are to develop and validate a classifier using multimodal passive sensor data and metrics derived from normal iPhone and Apple Watch usage to distinguish individuals with normal cognition from those with mild cognitive impairment (MCI) and to develop and validate a cognitive wellness score that tracks fluctuations in cognitive performance over time using multimodal passive sensor data and metrics derived from normal iPhone and Apple Watch usage.
