Kluver - Bucy syndrome
Gerstmann syndrome results from a lesion in
dominant parieto temporal cortex
s/sx of Wernicke encephalopathy
CAN
Confusion
Ataxia
Nystagmus
hemiballismus results from a lesion in
contralateral subthalamic nucleus
(lacunar stroke)
lesion at the amygdala (bilateral) results in
Kluver - bucy syndrome
lesion at the hippocampus (bilateral) results in
anterograde amnesia
inability to create new memories
common iatrogenic cause of central pontine myelinolysis
overly rapid correction of hyponatremia
bilateral occlusion of ACA can result in
behavioral change (abulia) urinary incontinence
artery involved in medial medullary syndrome

and vertebral artery
artery involved in wallenberg syndrome
PICA
especially affecting the nucleus ambiguus
locked - in syndrome results from a stroke in
basilar artery
lateral pontine syndrome results from a stroke in
AICA
PCOM aneurysm results in
CN III palsy
- eyes down and out
- ptosis
- mydriasis
risk of vasospasm in SAH occurs in
