question: I think my son may have had a mini stroke about a month ago that was not diagnosed because of other health concerns at the time. He is only 10 years old. His sypmptoms were extreme, sudden headache- he was screaming and holding his head, slurred speach, confusion, his blood pressure was extremely high,and his platelet count ws also very elevated at the time because of the other health issues I mentioned.  This happened 2 times within a couple of days and left him very ill. WOuld it still show on an mri? Is it important to diagnose at this point if it were a stroke?
