Monitoring of Delayed Ischemia After Subarachnoid Hemorrhage (MODISH)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

The goal in this research is to develop better ways to detect and treat the damage caused by bleeding in the brain.
Condition or disease
Patients who suffer from a bleeding in the brain (stroke or hemorrhage) often experience secondary complications that can occur up to 2 weeks after the initial bleeding. Complications can include decrease of consciousness, weakness or paralysis, difficulty with speech and language, and worsening of brain damage. These decrease a patient's chances for a good recovery. A brain scan will be used to determine the damage caused by the bleeding, and the brain's electrical activity will be monitored to detect abnormal activity. These measures will be analyzed together with routine medical information to better understand and diagnose complications.
