BRAIN INFARCTS

Question 1

Left MCA superior division

Answer 1

Righ face and arm weakness of UMN type and nonfluent or Broca’s aphasia (may also be some right face and arm cortical-type sensory loss)

Question 2

Left MCA inferior divisoin

Answer 2

Fluent, or Wernicke’s, aphasia and R visual field deficits. (may have R face and arm cortical type sensory loss) Motor findings are absent and pt may seem confused or crazy. Mild Right sided weakness

Question 3

Left MCA deep division

Answer 3

Rigt pure motor hemiparesis of UMN type. large infarcts may produce cortical deficits and aphasia as well

Question 4

Left MCA stem

Answer 4

Right pure motor hemiparesis of UMN type. Right hemiplegia, right hemianesthesia, right homonymous hemianopia, global aphasia. Often left gaze preference

Question 5

Right MCA superior division

Answer 5

Left face and arm weakness of UMN type, left hemineglect to a variable extent. May also be some left face and arm cortical type sensory loss

Question 6

Right MCA inferior division

Answer 6

Profound left hemineglect. Left visual field and somatosensory deficits. Motor neglect w/ decreased voluntary or spontaneous initation of movements on left side. Pt usually have normal motor strength on left side (occasional spontaneous movements on left side or withdrawl from pain). mild left sided weakness, Right gaze preference

Question 7

Right MCA deep territory

Answer 7

Left pure motor hemiparesis of UMN type. larger infarcts = cortical deficits such a left hemineglect

Question 8

Right MCA stem

Answer 8

Left pure motor hemiparesis of UMN type. Left hemianesthesia, left homonymous hemianopia, profound left hemineglect. right gaze preference

Question 9

Left ACA

Answer 9

Right leg weakness of UMN type and Right leg cortical type sensory loss. Grasp reflex, frontal lobe behavior abnormalities and transcortical aphasia. RIght hemineglect large infarcts can also cause R hemiplegia

Question 10

Right ACA

Answer 10

Left leg weakness of UMN typeand and left leg cortical type sensory loss. Grasp reflex, frontal lobe behavior abnormalities and transcortical aphasia. left hemineglect large infarcts can also cause left hemiplegia

Question 11

Left PCA

Answer 11

Right homonymous hemianopia, extension of to the splenium can cause alexia w/o araphia. Larger infarcts including thalamus, internal capsule may cause aphasia, right hemisensory loss and right hemiparesis

Question 12

Right PCA

Answer 12

Left homonymous hemianopia. Larger infarcts include thalamus and internal capsule may cause left hemisensory loss and left hemiparesis.
