58 Why should we consider organizing stroke care regionally? Networking will improve use of limited resources We can share continuing education activities We can share continuing education activities We can share limited diagnostic and therapeutic resources (e.g., subspecialty cerebrovascular disease care for complicated cases) We can share limited diagnostic and therapeutic resources (e.g., subspecialty cerebrovascular disease care for complicated cases) Imagine a new revolutionary treatment becomes available Imagine a new revolutionary treatment becomes available Improved patient access to clinical studies We can learn from and be stimulated by each others’ experiences and enthusiasm

59 CASES

60 Case 1

61 A 49 yo male was evaluated because of sudden left-sided numbness and weakness. Two weeks prior to my evaluation, he developed sudden numbness of the left arm and leg and he had difficulty moving the arm but he was able to drive his truck a short distance. He was evaluated at a small community hospital and his symptoms improved over the next couple of days. He had an MRI and was told it was normal and was discharged with a diagnosis of “neurologic migraine or RIND”. This caused confusion because he still had a sense of numbness and heaviness in the left arm and he felt like his thought processes were slowed. On examination, I found that he had mild weakness of the left arm and leg and some psychomotor slowing.
