The purpose of this research study is to determine if an already FDA approved drug called atorvastatin can help adults, age 75 or older, live well for longer by preventing dementia, disability, or heart disease. Participants will be assigned by chance to receive either atorvastatin (study drug) or a matching placebo (a tablet that looks like atorvastatin but does not contain any medicine). Study engagement may last up to five years and involves in clinic and/or remote visits, survey questions, potential blood draws, in addition to memory and physical tests. After the first 1-2 visits performed in clinic or remote, the study team will follow-up via phone on a yearly basis to see how participants are doing. Participants will be compensated for their time and participation in this research study.

The purpose of this study is to develop and test if upper limb task practice and muscle activity training improve upper limb function in stroke survivors. Participants will be asked to come to the laboratory 3 times a week for 6 weeks to receive upper limb task practice and/or muscle activity training. Participants will also come to the laboratory for additional 3 visits for assessments of upper extremity function. The total duration of the study will be 2.5 months.

Over 2400 people who have sickle cell disease and are between the ages of 15 and 45 have been enrolled into the National Registry (SCDIC-I) of patients with Sickle Cell Disease (SCD). A rich resource of natural history data, the SCDIC-I Registry has longitudinal data collected yearly since 2016 from patient surveys (e.g. self reported pain incidences, sleep, barriers to care, experiences during and after pregnancy), medical record abstraction (e.g. medications, transfusion history, co-morbidities) and laboratory results. The 150 patients (or 1200 among the 8 sites) will be selected from both MUSC adult and pediatric SCD clinics starting at 12 years of age; those not previously enrolled in the SCDIC National Registry will be offered the possibility to enroll in SCDIC-II.
We will look at the following:
1- Compare the effect of new SCD medications – crizanlizumab, voxelotor, and L-glutamine – on clinical outcomes in individuals with SCD.
2 - Identify genetic and genomic predictors of response to crizanlizumab, voxelotor, and L-glutamine
3 - Integrate study data into the CureSCi metadata catalog (MDC) to enhance future cross-study analyses.

Approximately 50% of people who have had a stroke report feelings of tiredness and/or a lack of energy that is not reduced with rest and sleep. This phenomenon is known as post-stroke fatigue. Post-stroke fatigue negatively affects an individual's quality of life and participation in rehabilitation, social, and physical activities. There are currently no known effective treatment options for people with post-stroke fatigue. This study will investigate the use of a non-invasive brain stimulation technique called transcranial magnetic stimulation (TMS) to treat post-stroke fatigue. This method has proven useful in other conditions such as depression and we will measure the effects of TMS on reducing fatigue in individuals more than six months post-stroke.

The purpose of this study is to identify domains in which stroke suvivors may have struggled since experiencing a stroke. These include things like emotional, family and work function. This study entails an interview and questionnaires that ask about functioning in these areas.

The longer-term goal of this work is to identify areas these areas so that we can develop a psychotherapy that could be helpful for individuals recovering from and living with the aftermath of stroke.

Sensory stimulation has been shown to enhance rehabilitation outcomes. However, most sensory stimulation devices interfere with natural hand tasks. Thus, a new wearable stimulation device has been developed to deliver imperceptible vibration to wrist skin. This study is to evaluate the community use of the device for patients with neurologic movement disorders. Participation will include wearing the provided device and charging the device every night. The knowledge regarding community use of the device may contribute to improving the device functionality and usability for future users of the device.

People who experience a stroke often have problems performing many different tasks during daily life. Most studies investigating stroke recovery and rehabilitation focus only on one type of task. The purpose of this research study is to measure individuals' function in many areas that can be affected by a stroke, such as their balance, mood, memory, reaching, and speech. This study will also track changes that can occur with task performance over time.

VERIFY will validate biomarkers of upper extremity (UE) motor outcome in the acute ischemic stroke window for immediate use in clinical trials, and explore these biomarkers in acute intracerebral hemorrhage. The central hypothesis is that patients have different UE outcomes depending on corticomotor system (CMS) function, measured as motor evoked potential (MEP) status with TMS, and on CMS structure, measured as acute lesion load with MRI. VERIFY will create the first multicenter, large-scale, prospective dataset of clinical, TMS, and MRI measures in the acute stroke time window.

The study team is recruiting 25 adults with spasticity due to chronic stroke for a 4 day study. In people with chronic stroke, one of the most common and disabling problems is spasticity (increased muscle tone or muscle stiffness). The purpose of this research study is to examine effects of dry needling on the nervous system (pathways between the muscle, spinal cord, and brain) in people with spasticity due to chronic stroke. Dry needling is a procedure in which a thin, stainless steel needle is inserted into the skin to produce a muscle twitch response. It is intended to release a knot in a person's muscle and relieve pain.

The total study duration is 3 visits over 4 days. The first visit will last about 3 hours, and the second and third visits will last about 1.5 hours. Dry needling will take place on the first visit only. During each visit the participant will be asked to participate in examinations of reflexes (muscle responses to non-invasive nerve stimulation) and leg function.

To assess comparable efficacy of aphasia therapy administered via telerehab (aphasia remote therapy; ART) to aphasia therapy administered in clinic (in-clinic therapy; I-CT).
