Above the necklace-Anterior Circulation= - Answer- Unilateral deficits
Below the necklace-Posterior circulation= - Answer- Bilateral deficits
Circle of Willis-Collateral circulation= - Answer- Aneurysm
Cerebrum - Answer- largest part of the brain
Cerebrum: Frontal Lobe - Answer- Motor function, personality, Brocca speech
Brocca's aphasia-frontal lobe - Answer- problem with the production and grammar
speech syntax, people know what they want to say but they cant produce the words.
temporal lobe - Answer- Seizure, Wernicke speech, hearing
Wernicke's aphasia (receptive aphasia)-temporal lobe - Answer- impaired auditory
reception; speech may be fluent but is often meaningless or nonsensical
parietal lobe - Answer- sensory input for touch and body position-neglect
-teach patient to scan the room
occipital lobe - Answer- vision
basal ganglia - Answer- Hypertensive bleed
Thalamus - Answer- sensory switchboard, located on top of the brainstem;
-Patient waxing and waning
-Patient asleep/awake
-Thalamic pain syndrome
thalamic pain syndrome - Answer- a condition caused by damage to the thalamus
resulting in burning or tingling sensations and possibly hypersensitivity to things that
would not normally be painful such as light touch or temperature change
,Cerebellum - Answer- Balance and coordination
Left (Dominant) Hemisphere Stroke - Answer- -Left gaze preference (looks toward
stroke area)
-Right hononomous hemianopia
-Right hemiparesis
-Right hemisensory loss
-Aphasia
Right (Nondominant) Hemisphere Stroke - Answer- -Right gaze preference
-Left hononomous hemianopia
-Left hemiparesis, plegia
-Left hemisensory loss
*Neglect-left
*Agnosia (failure to recognize objects)
Posterior circulating stroke syndromes= - Answer- Wallenburg (Medulla)
Horner's Syndrome
Wallenberg syndrome - Answer- Nystagmus, Vertigo
Horner's syndrome - Answer- ipsilateral ptosis
miosis
anhidrosis
Ipsilateral - Answer- on the same side of the body
Contralateral - Answer- on the opposite side of the body
Miosis - Answer- constricted pupils
anhidrosis - Answer- absence of sweating
Locked-in syndrome - Answer- PONS
How do you communicate with someone with locked-in syndrome? - Answer- Blinking
eye movement
Cerebral Venous Thrombosis - Answer- Hypercoagulopathy state
Post-partum/PREGNANCY
Carotid or Vertebral dissection-TRAUMA - Answer- Trauma most common cause
TX: anticoagulation
Arterio-venous Fistula - Answer- Ptosis-eyeball pops out
,Hears swishing
Carotid Cavernous Fistula - Answer- Arterial venous connection between carotid artery
and cavernous sinus---"the bulging red eye"
-can be high-flow or low-flow
-high flow results in patients with atherosclerosis and HTN with carotid aneurysms that
rupture within sinus or secondary to closed head trauma (*basal skull fracture*)
-S&S of high-flow: headache and confusion; *orbital bruit
Carotid cavernous fistula (CCF) - Answer- Type A-High pressure
Type B-Low pressure
Type C-Low pressure
Type D-Low pressure
Moyamoya disease - Answer- "Puff of Smoke"
Japanese, young female, genetic
Small, thin walled torturous arteries
Spontaneous stenosis, eventual occlusion
TX: antiplatelet, CCB, surgery
Moyamoya - Answer- Small, thin walled torturous arteries
TX: surgery-re-establish blood flow to ischemic area
SYNANGIOSIS- creation of new vessels
Vasculitis- - Answer- Inflammation of blood vessels
Answer: Steriod
cavernous angioma - Answer- "less common than AVM. Similar to cavernous angioma
elsewhere (liver). Formed by large irregular thin-walled vascular channels. Most are
asymptomatic, may cause bleeding, epilepsy, or focal neuro problems"
CT Scan=PURPLE LESION
Dural arteriovenous fistula - Answer- Abnormal arteriovenous shunts that occur in the
POSTERIOR DURA
Usually acquired from trauma and associated with obstruction of venous sinus
Stroke mimics - Answer- -Todd's Paralysis (postictal)
-migraine with aura
-Bell's Palsy
-Hypoglycemia
-MS
-Hypertensive encephalopathy
-Wernicke's
-Central venous sinus thrombosus
-ICH - SAH/SDH/EDH
-Brain tumor
, -Conversion disorder
-Meningitis/Encephalitis/Abscess
TIA - Answer- transient ischemic attack.... mini stroke, no dead tissue.
Warning sign of potential or future stroke
Symptoms resolve in minutes to hours
No permanent neurological deficits
Visual difficulties
Carotid stenosis
Carotid endarectomy
Ischemic stroke - Answer- a type of stroke that occurs when the flow of blood to the
brain is blocked
Neuroplasticity - Answer- is remodeling process of the brain
-creating new pathways via PT, OT, Speech
-Neuroplasticity of penumbra is continuous repetition of the deficit-ROBOTIC repetition.
Neuroplasticity & Stroke Recovery - Answer- Begins 1-3 days post stroke
-Regains lost function after injury
-Success of recovery depends on DESIRE of individual to gain functional ability
The BE FAST acronym stands for: - Answer- Balance
Eyes
Face
Arms
Speech
Time
7 D's of stroke care - Answer- Detection-Facial droop, arm weakness
Dispatch-Ambulance gets PT
Delivery-Pt deliver to ER
Door-Pt arrives
