we want to learn more about seizure activity while a patient with epilepsy is not seizing or is at "rest" using data from resting state intracranial EEG (rs-iEEG) and resting state functional MRI (rs-fMRI).

The purpose of the study is to establish a Clinical Cohort (group) of research participants to examine normal cognition, mild cognitive impairment and Alzheimer's disease and related disorders (ADRD) as people get older. We will be measuring changes in your memory and the way you process information as you age. As part of the study, you will be asked to participate in yearly evaluations of your memory and health. You will have brain imagining done by Magnetic Resonance Imaging (MRI), a lumbar puncture and blood will be drawn at some visits. Also, as part of this research you must designate a "project partner." This should be someone who is familiar with your health and will be able to provide information about your health and wellbeing as appropriate.

The ASPIRE trial aims to study anticoagulant medications in patients who have had an intracerebral hemorrhage (bleeding in the brain) who also have atrial fibrillation (irregular heartbeats). Participants who agree to study participation will receive either Aspirin or Apixaban and followed for 12-36 months to see if they have any other strokes, and follow their general recovery after stroke.

The purpose of this project is to create and distribute a survey with the intent to collect data about the amount and quality of training critical care physicians receive regarding brain death (i.e., death by neurologic criteria). We are doing because teaching physicians about brain death is not standardized and the subject is complex.

This study will gather information about patients who are taking new medicines for Alzheimer's disease. We'll keep an eye on how these patients are doing in the long run, tracking things like how they're responding to treatment, what their overall health outcomes are like, and how safe these new treatments really are when used in the real world. The goal of this study is to get a better understanding of how these therapies actually work for a diverse group of people, not just the people who usually participate in clinical trials.

The objective of the registry is to create a cohort of patients with NMOSD. This registry will be used for future research, as well as improvements to the diagnosis, treatment, and understanding of NMOSD.

This study compares two dose strengths of a new epilepsy medicine to placebo for treatment of refractory focal onset epilepsy as measured by the change in 28-day average seizure frequency.

This clinical trial aims to understand how well ALXN-C5IT works over a long time. We want to see if it can prevent relapses and help with disability, walking, and vision. We also want to know how patients feel about their health while using ALXN-C5IT.

The purpose of this study is to characterize the natural history of DRPLA patients using a variety of clinical and biomarker modalities and to identify genetic factors, biomarkers, and clinical measures that could predict disease progression.

We are collecting cerebral spinal fluid (CSF) from Normal Pressure Hydrocephaly (NPH) patients to generate a biosample research repository. This repository will be used to research CSF biomarkers for Alzheimer's disease that may enhance our ability to detect and monitor Alzheimer's disease diagnoses and progression.
