Vasculature Flashcards
Clinical Syndromes
What are the deficits
location of Infarct:
Left MCA Superior Division
Right face and arm weakness (upper motor neuron type)
Broca’s aphasia
Possible right face and arm sensory loss
What are the deficits
location of Infarct:
Left MCA Inferior Division
Fluent or Wernickes aphasia
RIght visual field deficit (Homonymous hemianopsia)
RIght face/arm sensory loss
At the onset patients may seem confused and have some right sided weakness
What are the deficits
location of Infarct:
Left MCA Deep Infarct
Right pure motor hemiparesis (upper motor neuron type) (causes weakness on one side of the body, affecting the face, arm, and leg, without other sensory or cortical symptoms)
other possible cotical deficits such as aphasias
a type of lacunar stroke that’s usually caused by an ischemic lesion in the internal capsule or pons
What are the deficits
location of Infarct:
Left MCA Stem
Right Hemiplegia (paralysis or weakness on one side of the body)
Right Hemianesthesia
Right Homonymous Hemianopsia (loss of half of a visual field)
Global Aphasia
Left gaze prefence, cant look right
What are the deficits
location of Infarct:
Right MCA superior division
Left face and arm weakness (upper motor neuron type)
Some left hemineglect
Some left face and arm sensory loss
What are the deficits
location of Infarct:
Right MCA inferior division
Left Hemineglect
Left Visual Field deficit
Left somatasensory deficit
Some left motor neglect , mild left side weakenss
Right gaze preference, difficulty looking left
What are the deficits
location of Infarct:
Right MCA deep territory
Left pure motor hemiparesis (upper motot neuron type): Paralysis of the face, arm, and leg on one side, without sensory signs or visual field defect
Some “cortical deficits” (such as left hemineglect)
What are the deficits
location of Infarct:
Right MCA stem
Left Hemiplegia (paralysis or weakness on one side of the body, typically affecting the arm, leg, and face)
Left Hemianesthesia ( loss of sensation in either half of the body)
Left Homonymous Hemianopia ( vision loss on the same side — left or right — in both eyes)
Profound Left Hemineglect
Right Gaze preference, cant look left
What are the deficits
location of Infarct:
Left ACA
Right leg weakness (upper motor neuron type)
Right leg sensory loss
Grasp Reflex
Frontal Lobe Behaviorl Abnormalities
Possible Transcortical Aphasia
Biggr infarcts can cause right hemiplegia (paralysis or weakness on one side of the body)
What are the deficits
location of Infarct:
Right ACA
Right Leg Weakness (upper motor neuron type)
Left leg sensory loss
Grasp Relfex
Frontal lobe behavioral abnormalities
Left hemineglect
Larger infarcts may cause left hemiplegia.
What are the deficits
location of Infarct:
Left PCA
Alexia withou Agraphia
Right Homonymous Hemianopia
Larger infarcts (including the Thalamus & Internal Capsule) can cause aphasia and R. Hemisensory loss and R. Hemiparesis … (remember these can kinds mimic MCA’s).
Common Symptoms of an ACA stroke
Contralateral Leg Weakness
Contralateral Lower Sensory Loss
Abulia
Anterograde Amnesia
Common Symptoms of a PCA stroke
Can look like MCA symptoms
Supplies the mid brain and THALAMUS
Contralateral Hemi-sensory Loss
Contralateral Hemianopia
Rarely neglect- improves quickly (which is how you can differentiate from MCA)
Trans cortical aphasia and global cog issues (behavior, memory)
