Cryptogenic Stroke or Stroke of "Unknown Cause"
A Patient's Guide to Understanding Strokes of Unknown Cause
In most cases, a stroke is caused by a blood clot that blocks blood flow to the brain. But in some instances, despite testing, the cause can’t be determined. Strokes without a known cause are called “cryptogenic”.
Because approximately 1 in 4 stroke survivors will likely have another stroke event, finding the cause of the stroke will help your physician treat the cause of your stroke and lower the likelihood of another event. Having a cryptogenic stroke may be frustrating and overwhelming, but with a proper diagnostic work-up and collaboration with your healthcare team, you can take part in finding the cause of your stroke and help prevent another one from occurring.
Below, we have information and resources that can help you and your loved ones partner with your healthcare team and find answers around cryptogenic stroke.
