People who have had any type of stroke recover best if they get treatment immediately. If you suspect a stroke based on the symptoms, have someone take you immediately to the emergency room, or call 911 to get help.
Doctors typically take a medical history and do a physical exam. Family and friends can describe the symptoms they saw, especially if the person who had the stroke is unconscious. The final diagnosis, however, is usually made based on how the blood is flowing in the brain. Imaging tests show areas of blood flow. These tests may be used to diagnose venous sinus thrombosis:
MRI scan
CT scan
Venography
Angiography
Ultrasound
Blood tests
