Genetic and Environmental Risk Factors for Hemorrhagic Stroke
The purpose of this study is to find risk factors for hemorrhagic stroke, specifically
intracerebral hemorrhage (ICH). ICH, a type of bleeding into brain tissue, is a type of
stroke that can result in death or disability in a large number of people. Our study hopes to
identify a specific genetic risk factor that will help identify at risk individuals and
target treatment strategies.

target treatment strategies.
Our case-control study will enroll subjects with a spontaneous ICH in the Greater Cincinnati
region. For each subject enrolled we will also enroll a healthy control subject(matched by
age , race and gender). Both the cases and control will undergo the same interview and have
blood drawn for genetic analysis. The cases will have a chart abstraction done on their event
medical record and be contacted for 3 and 6 month follow up(short interview). The genetic
sample will be genotyped using the Affymetrix 6.0 gene chip looking for SNPs of interest and
to identify genetic variants associated with ICH. The most promising SNPs identified through
this process will be replicated in the external cohort from Massachusetts General Hospital.

Inclusion Criteria:

- Resident (6 months or longer) within 100 miles of University of Cincinnati.
- Fulfillment of the criteria for spontaneous ICH
- No evidence of trauma, brain tumor/metastases, hemorrhagic transformation of ischemic
stroke or infectious processes as a cause of the hemorrhage.
- Ability of the patient or legal representative to provide consent for an interview,
