The PARIS study is a prospective study following recovery of patients with first ischemic stroke or intracerebral hemorrhage. The goal of this study is to understand the variability of stroke recovery. Strokes significantly differ in terms of etiology, location, clinical deficit, and prognosis. We collect information on subjects' previous medical problems, level of deficit after the stroke, magnetic resonance imaging findings, functional imaging characteristics, and hospital complications such as pneumonia or urinary tract infection. We then follow these subjects over a course of two years with serial questionnaires, neurological examinations, and some more sophisticated, noninvasive motor testing and imaging studies. With this information, we will be able to better predict recovery after stroke and hopefully enhance recovery based on the knowledge we gain.

Eligible Participants:

1. 18 years of age and older
2. Patient is hospitalized on the Columbia Neurovascular service
3. First clinical stroke evaluated within 72 hours of stroke onset (infarct or hematoma)
4. Deficits: hemiparesis, aphasia, or hemineglect
5. English or Spanish speaking
6. DWI positive lesion
7. Do not have dementia, major psychiatric illness at time of entry, other neurological condition (e.g., epilepsy, tumor, AVM, SAH), inability to sign consent, medical condition with life expectancy <2 years, prior clinical stroke, prior incidental/silent stroke on imaging
