What does stroke of the middle cerebral artery cause?

-Contralateral paralysis & sensory deficits in head, arm and upper body (upper body homunculus - motor and somatosensory cortex)
-Motor speech deficit = Broca's area

2

What does stroke of the anterior cerebral artery cause?

Contralateral paralysis & sensory deficits in lower body and extremity (lower body homunculus - motor and somatosensory cortex)

3

What does stroke of the posterior cerebral artery produce?

Blindness in the contralateral visual field.

4

What does occlusion of the Posterior Inferior Cerebellar Artery (PICA) cause?

Lateral Medullary Syndrome/Wallenburg Syndrome -Clinical symptoms include swallowing difficulty, or dysphagia,[1] slurred speech, ataxia, facial pain, vertigo, nystagmus, Horner's syndrome, diplopia, and possibly palatal myoclonus.

What are the two main types of stroke?

1. Occlusion of a vessel by a thrombus or embolus --> Ischemia --> Infarction and/or necrosis
2. Hemorrhage from a vessel (often associated with hypertension)
-Intracerebral (perforating vessels)
-Aneurysm

6

What is the calcarine artery a branch of? What does a stroke here cause?
