A 67 years old man presents with rapid onset of right-sided weakness and a subjective feeling of decreased sensation on his right side. His family reported that he seemed to have difficulty forming sentences. Symptoms were maximal within a minute and began to spontaneously abate 5 minutes later. On arrival, 30 minutes after onset, his clinical deficits had largely resolved with the exception of a subtle weakness of his right hand. His history is significant for hypertension, diabetes, hyperlipidemia, and a 50 pack-year smoking habit. What are the most important differential diagnoses?

Of the relevant differential diagnoses, it is important to rule out stroke, brain tumor, aneurysm, intracerebral hemorrhage, and hyperensive and encephalopathy.
