Term

|
Term
|
Definition
| contralateral face and arm paralysis and sensory loss, aphasia (dominant sphere), L sided neglect |
|
|
Term

|
|
Term
| anterior communicating artery |
|
Definition
| most common site of circle of Willis aneurysm; lesions --> visual field defects |
|
|
Term
| posterior communicating artery |
|
Definition
| common area of aneurysm; CN 3 palsy |
|
|
Term
|
Definition

|
|
Term
|
Definition
| infarct causes "locked in syndrome"; CN 3 is typically intact |
