Dementia Paid Clinical Trials in Iowa

Ruptured cerebral aneurysms lead to subarachnoid hemorrhage (SAH),that has a high morbidity and mortality rate, the severity of which is predicted by the "Hunt-Hess grade" (HHG). SAH leads to iron (Fe) and hemoglobin (Hb) accumulation in the brain, which is toxic for neurons. Ferritin (iron reported in the brian) and iron overload leads to brain atrophy, specifically in the mesial temporal lobe (hippocampus, impairing patients' cognition. It is estimated that 50% of survivors have cognitive deficits. Most of the survivors of SAH could not return to work. Iron chelation therapy has been recently gaining ground as a therapeutic intervention in intraparenchymal hemorrhage and in SAH. However, there has not been any study that assess the iron deposition in the brain and the level of ferritin in the cerebrospinal fluid of SAH patients. The investigators propose to conduct a randomized trial using Deferiprone (oral chelating agent, "De") + standard of care versus standard of care in patient with SAH to: 1. assess the level of ferritin (Ft) in CSF (CSF withdrawn from ventriculostomy tube), 2. assess functional outcomes measured by the Montreal Cognitive Assessment (MoCA) score, a score used to assess the level of dementia, mainly in Alzheimer disease patients. 3. quantify the the total iron deposition in the brain based on MRI Read Less

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) Study has been to validate biomarkers for Alzheimer's disease (AD) clinical trials. ADNI4 continues the previously funded ADNI1, ADNI-GO, ADNI2, and ADNI3 studies that have combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of AD.

The overall goal of the DISCOVERY study is to better understand what factors contribute to changes in cognitive (i.e., thinking and memory) abilities in patients who experienced a stroke. The purpose of the study is to help doctors identify patients at risk for dementia (decline in memory, thinking and other mental abilities that significantly affects daily functioning) after their stroke so that future treatments may be developed to improve outcomes in stroke patients. For this study, a "stroke" is defined as either (1) an acute ischemic stroke (AIS, or blood clot in the brain), (2) an intracerebral hemorrhage (ICH, or bleeding in the brain), (3) or an aneurysmal subarachnoid hemorrhage (aSAH, or bleeding around the brain caused by an abnormal bulge in a blood vessel that bursts). The investigators hypothesize that: 1. The size, type and location of the stroke play an important role in recovery of thinking and memory abilities after stroke, and pre-existing indicators of brain health further determine the extent of this recovery. 2. Specific stroke events occurring in individuals with underlying genetic or biological risk factors can cause further declines in brain heath, leading to changes in thinking and memory abilities after stroke. 3. Studying thinking and memory alongside brain imaging and blood samples in patients who have had a stroke allows for earlier identification of declining brain health and development of individualized treatment plans to improve patient outcomes in the future.

PREVENTABLE is a multi-center, randomized, parallel group, placebo-controlled superiority study. Participants will be randomized 1:1 to atorvastatin 40 mg or placebo. This large study conducted in community-dwelling older adults without cardiovascular disease (CVD) or dementia will demonstrate the benefit of statins for reducing the primary composite of death, dementia, and persistent disability and secondary composites including mild cognitive impairment (MCI) and cardiovascular events.
