| A | B |
|---|
| left MCA superior division | right face and arm weakness of the upper motor neuron type, and nonfluent or Broca's aphasiaa |
| Left MCA inferior division | Fluent or Wernicke's aphasia and right visual field defect; there may also be some right face and arm cortical-type sensory loss |
| Left MCA deep territory | right pure motor hemiparesis of the upper motor neuron type. Larger infarcts may produce cortical deficits as well, such as aphasia |
| Left MCA stem | ight pure motor hemiparesis of the upper motor neuron type,with right hemiplegia, right hemianesthesia, right homonymous hemianopia and global aphasia. |
| Right MCA superior division | left face and arm weakness of UMN type. Left hemineglect as well as left face and arm cortical type sensory loss to variable extent |
| Right MCA inferior division | profound hemineglect |
| Right MCA deep territory | left pure motor hemiparesis of the UMN type |
| Right MCA stem | left pure motor hemiparesis of UMN type and left: hemiplegia,hemianesthesia, homonymous hemianopia and profound left hemineglect, usually right gaze preference |
| Left ACA | Right leg weakness UMN type; right leg cortical sensory loss, grasp reflex, frontal lobe behavior abnormalities transcortical aphasia |
| Right ACA | Left leg weakness UMN type; left leg cortical sensory loss, grasp reflex, frontal lobe behavior abnormalities and left hemi neglect |
| Left PCA | right homonymous hemianopia |
| extension of PCA infarct to splenium of corpus callosum | alexia without agraphia |
| larger infarcts of left PCA including thatlamus and internal capsule | aphasia, right hemisensory loss and right hemiparesis |
| larger infarcts of left PCA including thatlamus and internal capsule | right hemisensory loss and right hemiparesis |
| Right PCA | left homonymous hemianopia |
