Stroke - Diagnosis
Rapid diagnosis is essential in successful treatment of stroke. A doctor will first look for symptoms. He or she will then look at the patient's medical history for the presence of risk factors in the patient's background and a description of when and how symptoms appeared.
If stroke is suspected, more sophisticated tools are used for diagnosis. Imaging techniques will show whether the stroke was caused by a blood clot or a hemorrhage. This information is needed to begin the correct type of treatment. Blood and urine tests are also carried out. Other tests used to determine if a stroke has occurred include an electrocardiogram, angiography, or ultrasound tests.
