Conversation: The conversation between human and AI assistant.
[|Human|] I have two questions for you, if you are able and willing t answer I will truly appreciate it. I m really scared of having a stroke, and my question is: Can you have a stroke with normal blood pressure? The second question is: Can the docs see a blood clot or anything irregularity with the brain and their vessels with a CT Scan with out contrast? Went to the ER with tingling in my head and burning in my thigh, and the doc said that the CT Scan came out normal. It still has me worried that I might have a clot, my blood pressure was normal a 120 over 70.
[|AI|]  Hi, Yes, there are instances when one can have a stroke with normal blood pressure like in patients who are normotensive with heartbeat irregularities (like Atrial Fibrillation), as well those with blood vessel abnormalities like amyloid antipathy. CT scan of the brain may show signs of either bleeding or infarction, but there are instances when it may be normal especially when done very early in those with infarcts (caused by clots) which may be more evident when done in a few more hours. But the importance of doing an early CT scan is to rule out hemorrhage in those who present clinically with stroke. I would suggest that a consult be done if your symptoms are persistent for further work-up and appropriate treatment.  Hope I have answered your query. Let me know if I can assist you further.
