<s>[INST] What do I do if I think I’m having a stroke? [/INST] It is imperative that you call 9-1-1 immediately. “Time is brain” and every second that passes causes more brain injury. Studies have been done that show that after 12 minutes without treatment a pea-sized piece of brain tissue dies. It is also important that you remember and record the time the stroke symptoms started. The time of symptom onset will be an important piece of information that will affect your treatment options once you are in the hospital. Source: STROKE SUPPORT ASSOCIATION.
