Stroke Basics
This types of stroke accounts for ~87% of all strokes
What os ischemic stroke
The lobe responsible for movement and executive function.
What is the frontal lobe?
Loss of speech due to left MCA stroke.
What is aphasia?
The most common type of TBI, often called a “mild brain injury.”
What is a concussion?
ICP above this level is considered dangerous.
What is >20 mmHg?
The “golden window” for giving tPA in an ischemic stroke is within how many hours?
3-4.5 hours
The ACA stroke primarily affects this body region.
What is the contralateral lower extremity?
Ignoring one side of the body/environment due to right MCA stroke.
What is neglect?
A bruise on the brain caused by coup-contrecoup injury.
What is a contusion?
Abnormal bone formation in soft tissues after TBI.
What is heterotopic ossification (HO)?
A mini-stroke with symptoms that resolve within 24 hours is called this.
What is a transient ischemic attack (TIA)?
This artery supplies the visual cortex.
What is the posterior cerebral artery (PCA)?
Inability to recognize body parts or denial of deficit.
What is anosognosia or asomatognosia?
Arterial bleed between the skull and dura, often with a lucid interval.
What is an epidural hematoma?
Seizures after TBI may be treated with these two common medications.
What are Phenytoin (Dilantin) and Phenobarbital (Luminal)?
The most important modifiable risk factor for stroke
What is hypertension?
An occlusion of this artery is most common in ischemic strokes.
What is the middle cerebral artery (MCA)?
Burning, painful sensation after a thalamic lesion.
What is thalamic pain syndrome?
Damage caused by high-speed rotational forces shearing axons.
What is diffuse axonal injury (DAI)?
Sympathetic nervous system overdrive after TBI, also called “brain storming.
What is paroxysmal sympathetic hyperactivity (PSH)?
This imaging test is faster in the ER and helps rule out hemorrhage before giving tPA.
What is a CT scan?
Locked-in syndrome results from occlusion of this artery system.
What is the vertebrobasilar artery?
Pushing toward the weak side and resisting correction.
What is Pusher Syndrome?
This rare syndrome leaves a patient fully conscious but unable to move except eye muscles.
What is Locked-in Syndrome?
Clear drainage from the nose or ear after TBI may indicate this dangerous complication.
What is a CSF leak?
