1. MSK
2. Integumentary
3. Pulmonary
4. Cardiovascular
- 5th leading cause of death
- Leading cause of long-term disability in adults in US
- Women lower risk until over 85 then assume higher risk than men
- Highest in African Americans, Mexican Americans, American Indians, Alaskan Natives
Epidemiology and etiology
Which type of stroke:
thrombosis, embolism, hypoperfusion
Ischemic
TIA, minor stroke, major stroke, deteriorating stroke, young stroke
Management categories
Which type of stroke:
Rupture, bleed
Hemorrhage
With this kind of stroke, the deficits are more severe.
Hemorrhagic
Name the management category:
Stable, severe impairments
Major stroke **
Name the management category:
Symptoms no greater than 24 hours **
Transient ischemic attack **
Name the management category:
Neuro status worsens after admission, not stable, (same as progressive stroke)
Deteriorating stroke **
Name the management category:
Stable, minimal impairments
Minor stroke ***
Name the management category:
Age less than 45
Young stroke
Name the type of pharmacological management:
Ischemic stroke management, clot buster, can be given within the first 2-3 hours after onset of symptoms
Thrombolytics -- Tissue plasminogen activator (tPA) **
Name the type of imaging:
Acute phase of stroke, most readily available; ischemia or hemorrhage rule out (tells you which one it is), first line of action when patient comes to ER
Computed tomography (CT)
Name the type of pharmacological management:
Thin blood to reduce clotting risk and prevent existing clots from expanding (EX: Heparin)
Anticoagulants **
Name the type of imaging:
Increased sensitive, contraindicated with pacemakers
Magnetic resonance imaging (MRI)
Name the type of pharmacological management:
Control HTN (EX: beta blocker)
Antihypertensive agents **
What does the FAST acronym stand for?
F - Face drooping
A - arm weakness
S - speech difficulty
T - time to call 911 ***
Managed BP, healthier diet, cholesterol, exercising, obesity, smoking
Modifiable risk factors
Possible deficits:
Contralateral hemiparesis and sensory loss with greater involvement of the LE than the UE because the somatotopic organization of the medial aspect of the cortex includes the functional area for the LE
Anterior cerebral artery syndrome
Name the type of pharmacological management:
Prevents clumping of platelets (EX: aspirin)
Antiplatelet therapy **
- ACA syndrome
- MCA syndrome
- Internal carotid artery syndrome
- PCA syndrome
- Lacunar stroke
- Vertebrobasilar artery syndrome
Vascular syndromes
What is the most common site of occlusion in stroke?
MCA
Possible deficits:
- Contralateral sensory loss or central poststroke thalamic pain
- Homonymous hemianopsia, visual agnosia, prosopagnosia, or if bilateral cortical blindness
- Amnesia
- Wide variety of effects in subthalamic structures involved
- Contralateral hemiplegia
Posterior cerebral artery syndrome
Possible deficits:
- Produces massive infarction in the region of the brain supplied by the MCA
- Supplies both the MCA and ACA. If collateral circulation to the ACA from the circle of willis is absent, extensive cerebral infarction in the areas of both the ACA and MCA can occur. Significant edema is common with possible uncal herniation, coma, and death
Internal carotid artery syndrome
Possible deficits:
- contralateral spastic hemiparesis and sensory loss of the face, UE, and LE with the face and UE more involved than the LE
- Aphasia
- Perceptual deficits (EX: unilateral neglect, anosognosia, apraxia, and spatial disorganization)
- Homonymous hemianopsia is also a common finding
Middle cerebral artery syndrome
